Modernization of 50-year-old compressor station produces savings for NGPL  

Science Conference Proceedings (OSTI)

Modernization of Natural Gas Pipeline Co. of America's 50-year-old compressor Station 108 at Truro, Iowa, will save NGPL about $450,000/year in fuel costs and reduce maintenance expenses. Station modernization, which began in 1983 and was completed the following summer, was part of a longterm construction program designed to increase the efficiency of NGPL's mainline system from Beatrice, Neb., to Chicago, Truro's 10 horizontal engines - half of them more than 50 years old - were replaced with 3 highly efficient, fuel-saving 5,500-hp Cooper-Bessemer vertical engines. Five of the old horizontals were 1,750-hp Worthingtons which had accumulated 1.6 million operating hr since installation in 1931. The other five units replaced were 1.750-hp Cooper-Bessemers installed in 1948. The new supervisory control and data acquisition (SCADA) system at Station 108, designed by NGPL with Digital Equipment computer and Texas Instruments programmable logic controller (PLC), is as advanced as the engines it monitors.

Hydride compressor  

DOE Patents (OSTI)

Method of producing high energy pressurized gas working fluid power from a low energy, low temperature heat source, wherein the compression energy is gained by using the low energy heat source to desorb hydrogen gas from a metal hydride bed and the desorbed hydrogen for producing power is recycled to the bed, where it is re-adsorbed, with the recycling being powered by the low energy heat source. In one embodiment, the adsorption-desorption cycle provides a chemical compressor that is powered by the low energy heat source, and the compressor is connected to a regenerative gas turbine having a high energy, high temperature heat source with the recycling being powered by the low energy heat source.

Supersonic compressor  

DOE Patents (OSTI)

A gas compressor based on the use of a driven rotor having an axially oriented compression ramp traveling at a local supersonic inlet velocity (based on the combination of inlet gas velocity and tangential speed of the ramp) which forms a supersonic shockwave axially, between adjacent strakes. In using this method to compress inlet gas, the supersonic compressor efficiently achieves high compression ratios while utilizing a compact, stabilized gasdynamic flow path. Operated at supersonic speeds, the inlet stabilizes an oblique/normal shock system in the gasdyanamic flow path formed between the gas compression ramp on a strake, the shock capture lip on the adjacent strake, and captures the resultant pressure within the stationary external housing while providing a diffuser downstream of the compression ramp.

Recirculating rotary gas compressor  

DOE Patents (OSTI)

A positive displacement, recirculating Roots-type rotary gas compressor is described which operates on the basis of flow work compression. The compressor includes a pair of large diameter recirculation conduits which return compressed discharge gas to the compressor housing, where it is mixed with low pressure inlet gas, thereby minimizing adiabatic heating of the gas. The compressor includes a pair of involutely lobed impellers and an associated port configuration which together result in uninterrupted flow of recirculation gas. The large diameter recirculation conduits equalize gas flow velocities within the compressor and minimize gas flow losses. The compressor is particularly suited to applications requiring sustained operation at higher gas compression ratios than have previously been feasible with rotary pumps, and is particularly applicable to refrigeration or other applications requiring condensation of a vapor. 12 figs.

Supersonic gas compressor  

Science Conference Proceedings (OSTI)

A gas compressor based on the use of a driven rotor having a compression ramp traveling at a local supersonic inlet velocity (based on the combination of inlet gas velocity and tangential speed of the ramp) which compresses inlet gas against a stationary sidewall. In using this method to compress inlet gas, the supersonic compressor efficiently achieves high compression ratios while utilizing a compact, stabilized gasdynamic flow path. Operated at supersonic speeds, the inlet stabilizes an oblique/normal shock system in the gasdyanamic flow path formed between the rim of the rotor, the strakes, and a stationary external housing. Part load efficiency is enhanced by the use of a pre-swirl compressor, and using a bypass stream to bleed a portion of the intermediate pressure gas after passing through the pre-swirl compressor back to the inlet of the pre-swirl compressor. Inlet guide vanes to the compression ramp enhance overall efficiency.

Standing wave compressor  

DOE Green Energy (OSTI)

A compressor for compression-evaporation cooling systems, which requires no moving parts. A gaseous refrigerant inside a chamber is acoustically compressed and conveyed by means of a standing acoustic wave which is set up in the gaseous refrigerant. This standing acoustic wave can be driven either by a transducer, or by direct exposure of the gas to microwave and infrared sources, including solar energy. Input and output ports arranged along the chamber provide for the intake and discharge of the gaseous refrigerant. These ports can be provided with optional valve arrangements, so as to increase the compressor's pressure differential. The performance of the compressor in either of its transducer or electromagnetically driven configurations, can be optimized by a controlling circuit. This controlling circuit holds the wavelength of the standing acoustical wave constant, by changing the driving frequency in response to varying operating conditions.

Compressor surge counter  

DOE Patents (OSTI)

A surge counter for a rotating compressor is provided which detects surging by monitoring the vibration signal from an accelerometer mounted on the shaft bearing of the compressor. The circuit detects a rapid increase in the amplitude envelope of the vibration signal, e.g., 4 dB or greater in less than one second, which is associated with a surge onset and increments a counter. The circuit is rendered non-responsive for a period of about 5 seconds following the detection which corresponds to the duration of the surge condition. This prevents multiple registration of counts during the surge period due to rapid swings in vibration amplitude during the period.

Light intensity compressor  

DOE Patents (OSTI)

In a system for recording images having vastly differing light intensities over the face of the image, a light intensity compressor is provided that utilizes the properties of twisted nematic liquid crystals to compress the image intensity. A photoconductor or photodiode material that is responsive to the wavelength of radiation being recorded is placed adjacent a layer of twisted nematic liquid crystal material. An electric potential applied to a pair of electrodes that are disposed outside of the liquid crystal/photoconductor arrangement to provide an electric field in the vicinity of the liquid crystal material. The electrodes are substantially transparent to the form of radiation being recorded. A pair of crossed polarizers are provided on opposite sides of the liquid crystal. The front polarizer linearly polarizes the light, while the back polarizer cooperates with the front polarizer and the liquid crystal material to compress the intensity of a viewed scene. Light incident upon the intensity compressor activates the photoconductor in proportion to the intensity of the light, thereby varying the field applied to the liquid crystal. The increased field causes the liquid crystal to have less of a twisting effect on the incident linearly polarized light, which will cause an increased percentage of the light to be absorbed by the back polarizer. The intensity of an image may be compressed by forming an image on the light intensity compressor.

Heat-actuated metal hydride hydrogen compressor testing  

SciTech Connect

Electric utilities use hydrogen for cooling turbine generators. The majority of the utilities purchase the gas from industrial gas markets. On-site electrolytic hydrogen production may prove advantageous both logistically and economically. In order to demonstrate this concept, Public Service Electric and Gas Co. (PSE and G) and EPRI installed an electrolyzer at the Sewaren (NJ) station. To compress the gas, PSE and G purchased a heat-activated metal hydride compressor from Ergenics, Inc. This report describes closed- and open-cycle tests conducted on this metal hydride hydrogen compressor. Test systems, plans, methodologies, and results are presented. A brief discussion evaluates these performance results, addresses some of the practical problems involved with electrolyzer-compressor interface, and compares the costs and benefits of metal hydride versus mechanical hydrogen compression for utility generator cooling.

Energy Savings for Centrifugal Compressors  

E-Print Network (OSTI)

Current design improvements of both the rotating and stationary aerodynamic components of centrifugal compressors can greatly increase the efficiency of vintage machines. A centrifugal compressor built in the 1970's or 1980's might have an external polytropic efficiency in the high 70's, whereas a newer compressor might have an efficiency over 85 percent. Centrifugal compressors are designed to operate at a best efficiency point (BEP) shown on its performance map. Whether a centrifugal compressor is operating at its BEP, near choke, near the surge point, or in recycle, the operator may be able to significantly reduce the total energy consumption by rerating the installed machine with new, higher efficiency aero components. Whether the compressor is driven by an electric motor, steam turbine or gas turbine, costs for operating these drivers is ever increasing and how much it may go up in the future is uncertain. With a greater worldwide focus on protecting the environment by reducing greenhouse gases, improving the efficiency of an installed centrifugal compressor by rerating can go a long way toward that goal. This paper will explain the reasons for rerating a compressor and provide details of the rerate process.

Free piston inertia compressor  

DOE Patents (OSTI)

A free piston inertia compressor comprises a piston assembly including a connecting rod having pistons on both ends, the cylinder being split into two substantially identical portions by a seal through which the connecting rod passes. Vents in the cylinder wall are provided near the seal to permit gas to excape the cylinder until the piston covers the vent whereupon the remaining gas in the cylinder functions as a gas spring and cushions the piston against impact on the seal. The connecting rod has a central portion of relatively small diameter providing free play of the connecting rod through the seal and end portions of relatively large diameter providing a limited tolerance between the connecting rod and the seal. Finally, the seal comprises a seal ring assembly consisting of a dampener plate, a free floating seal at the center of the dampener plate and a seal retainer plate in one face of the dampener plate.

NGPL Louisiana station nears completion  

Science Conference Proceedings (OSTI)

Construction on a 3,600-hp compressor station on the Louisiana line of Natural Gas Pipeline Co. of America near Henry, La., was scheduled for completion later this month. The Louisiana line extends some 205 miles along the Gulf Coast between New Caney, Tex., and the Henry hub area. The new compressor station will be located about 44 miles west of the Henry hub. Work began on the $5.1 million expansion project in Cameron Parish, La., in May following Federal Energy Regulatory Commission (FERC) certification. By mid-September, the compressor building, service building, and meter house has been erected, final compressor inspections were under way, and gas piping tie-ins had been completed, according to NGPL. Powered by three 1,200-hp Solar Saturn gas-fired centrifugal engines, the station is designed to increase the capacity of the Louisiana line east of the Stingray pipeline system by up to 220 MMcfd. Current capacity for east bound flows is approximately 900 MMcfd.

Semi-active compressor valve  

SciTech Connect

A method and system for fine-tuning the motion of suction or discharge valves associated with cylinders of a reciprocating gas compressor, such as the large compressors used for natural gas transmission. The valve's primary driving force is conventional, but the valve also uses an electromagnetic coil to sense position of the plate (or other plugging element) and to provide an opposing force prior to impact.

Centrifugal compressor surge and speed control  

E-Print Network (OSTI)

AbstractPrevious work on stabilization of compressor surge is extended to include control of the angular velocity of the compressor. First a low-order centrifugal compressor model is presented where the states are mass flow, pressure rise, and rotational speed of the spool. Energy transfer considerations are used to develop a compressor characteristic. In order to stabilize equilibria to the left of the surge line, a close coupled valve is used in series with the compressor. Controllers for the valve pressure drop and spool speed are derived. Semiglobal exponential stability is proved using a Lyapunov argument. Index Terms Compressors, Lyapunov methods, modeling, surge control.

Multiple volume compressor for hot gas engine  

DOE Patents (OSTI)

A multiple volume compressor for use in a hot gas (Stirling) engine having a plurality of different volume chambers arranged to pump down the engine when decreased power is called for and return the working gas to a storage tank or reservoir. A valve actuated bypass loop is placed over each chamber which can be opened to return gas discharged from the chamber back to the inlet thereto. By selectively actuating the bypass valves, a number of different compressor capacities can be attained without changing compressor speed whereby the capacity of the compressor can be matched to the power available from the engine which is used to drive the compressor.

High efficiency compressor uses direct drive  

Science Conference Proceedings (OSTI)

This article focuses on the high efficiency of a compressor which uses only direct drive. This compressor was evaluated by judges and won Top Honors in the 1982 Chemical Processing magazine Vaaler Awards category of compressors, blowers and fans. Applications for the compressor include combustion air, process air and gas booster, incineration, fermentation, and vacuum filtration systems. In addition to a 50% reduction in power comsumption, the use of the compressor eliminated the need for a water seal, thus saving 200 gpm of water. And, since the elimination of the water seal reduced the necessary downtime for seal maintenance, on stream time was increased by 5%.

Optimization of compression and storage requirements at hydrogen refueling stations.  

SciTech Connect

The transition to hydrogen-powered vehicles requires detailed technical and economic analyses of all aspects of hydrogen infrastructure, including refueling stations. The cost of such stations is a major contributor to the delivered cost of hydrogen. Hydrogen refueling stations require not only dispensers to transfer fuel onto a vehicle, but also an array of such ancillary equipment as a cascade charging system, storage vessels, compressors and/or pumps/evaporators. This paper provides detailed information on design requirements for gaseous and liquid hydrogen refueling stations and their associated capital and operating costs, which in turn impact hydrogen selling price at various levels of hydrogen demand. It summarizes an engineering economics approach which captures the effect of variations in station size, seasonal, daily and hourly demand, and alternative dispensing rates and pressures on station cost. Tradeoffs in the capacity of refueling station compressors, storage vessels, and the cascade charging system result in many possible configurations for the station. Total costs can be minimized by optimizing that configuration. Using a methodology to iterate among the costs of compression, storage and cascade charging, it was found that the optimum hourly capacity of the compressor is approximately twice the station's average hourly demand, and the optimum capacity of the cascade charging system is approximately 15% of the station's average daily demand. Further, for an hourly demand profile typical of today's gasoline stations, onsite hydrogen storage equivalent to at least 1/3 of the station's average daily demand is needed to accommodate peak demand.

Oil cooled, hermetic refrigerant compressor  

DOE Patents (OSTI)

A hermetic refrigerant compressor having an electric motor and compressor assembly in a hermetic shell is cooled by oil which is first cooled in an external cooler and is then delivered through the shell to the top of the motor rotor where most of it is flung radially outwardly within the confined space provided by the cap which channels the flow of most of the oil around the top of the stator and then out to a multiplicity of holes to flow down to the sump and provide further cooling of the motor and compressor. Part of the oil descends internally of the motor to the annular chamber to provide oil cooling of the lower part of the motor, with this oil exiting through vent hole also to the sump. Suction gas with entrained oil and liquid refrigerant therein is delivered to an oil separator from which the suction gas passes by a confined path in pipe to the suction plenum and the separated oil drops from the separator to the sump. By providing the oil cooling of the parts, the suction gas is not used for cooling purposes and accordingly increase in superheat is substantially avoided in the passage of the suction gas through the shell to the suction plenum. 3 figs.

XMill: an Efficient Compressor for XML Data  

E-Print Network (OSTI)

We describe a tool for compressing XML data, with applications in data exchange and archiving, which usually achieves about twice the compression ratio of gzip at roughly the same speed. The compressor, called XMill, incorporates and combines existing compressors in order to apply them to heterogeneous XML data: it uses zlib, the library function for gzip, a collection of datatype specific compressors for simple data types, and, possibly, user defined compressors for application specific data types. 1 Introduction We have implemented a compressor/decompressor for XML data, to be used in data exchange and archiving, that achieves about twice the compression rate of general-purpose compressors (gzip), at about the same speed. The tool can be downloaded from www.research.att.com/sw/tools/xmill/.

SCREW COMPRESSOR CHARACTERISTICS FOR HELIUM REFRIGERATION SYSTEMS  

SciTech Connect

The oil injected screw compressors have practically replaced all other types of compressors in modern helium refrigeration systems due to their large displacement capacity, minimal vibration, reliability and capability of handling helium's high heat of compression.At the present state of compressor system designs for helium systems, typically two-thirds of the lost input power is due to the compression system. Therefore it is important to understand the isothermal and volumetric efficiencies of these machines to help properly design these compression systems to match the refrigeration process. This presentation summarizes separate tests that have been conducted on Sullair compressors at the Superconducting Super-Collider Laboratory (SSCL) in 1993, Howden compressors at Jefferson Lab (JLab) in 2006 and Howden compressors at the Spallation Neutron Source (SNS) in 2006. This work is part of an ongoing study at JLab to understand the theoretical basis for these efficiencies and their loss

Economics of Electric Compressors for Gas Transmission  

E-Print Network (OSTI)

Three new factors are coming together to motivate gas pipeline firms to consider electric motors for replacement of older reciprocating gas engines for compressor systems, and for new compressor installations. These factors are environmental regulations, economics, and new compressor technology. In ozone Non-Attainment regions, it is necessary to bring gas compressors into compliance with NOx regulations, and replacement with new electric systems represents a Lowest Achievable Emission Rate (LAER) option. Outside of these regions, new electric drives as well as gas fueled reciprocating engines and turbines are being considered for replacement of older reciprocating gas engines and compressor units, based on improved operating efficiency. We review here the impacts of the Clean Air Act Amendments of 1990 and economics on the selection process for considering electric drives versus alternatives for both ozone Non-Attainment areas and Attainment areas.

Refrigeration system having standing wave compressor  

DOE Patents (OSTI)

A compression-evaporation refrigeration system, wherein gaseous compression of the refrigerant is provided by a standing wave compressor. The standing wave compressor is modified so as to provide a separate subcooling system for the refrigerant, so that efficiency losses due to flashing are reduced. Subcooling occurs when heat exchange is provided between the refrigerant and a heat pumping surface, which is exposed to the standing acoustic wave within the standing wave compressor. A variable capacity and variable discharge pressure for the standing wave compressor is provided. A control circuit simultaneously varies the capacity and discharge pressure in response to changing operating conditions, thereby maintaining the minimum discharge pressure needed for condensation to occur at any time. Thus, the power consumption of the standing wave compressor is reduced and system efficiency is improved.

Compressor ported shroud for foil bearing cooling  

DOE Patents (OSTI)

A compressor ported shroud takes compressed air from the shroud of the compressor before it is completely compressed and delivers it to foil bearings. The compressed air has a lower pressure and temperature than compressed outlet air. The lower temperature of the air means that less air needs to be bled off from the compressor to cool the foil bearings. This increases the overall system efficiency due to the reduced mass flow requirements of the lower temperature air. By taking the air at a lower pressure, less work is lost compressing the bearing cooling air.

A supersonic gas compressor with bleed gas collectors, and a method of starting the compressor. The compressor includes aerodynamic duct(s) situated for rotary movement in a casing. The aerodynamic duct(s) generate a plurality of oblique shock waves for efficiently compressing a gas at supersonic conditions. A convergent inlet is provided adjacent to a bleed gas collector, and during startup of the compressor, bypass gas is removed from the convergent inlet via the bleed gas collector, to enable supersonic shock stabilization. Once the oblique shocks are stabilized at a selected inlet relative Mach number and pressure ratio, the bleed of bypass gas from the convergent inlet via the bypass gas collectors is effectively eliminated.

Surge and Choke Capable Compressor Model  

E-Print Network (OSTI)

Abstract: A compressor model is developed. It is capable of representing mass flow and pressure characteristic for three different regions: surge, normal operation as well as for when the compressor acts as a restriction, i.e. having a pressure ratio of less than unity. Different submodels are discussed and methods to parametrize the given model structure are given. Both the parametrization and validation are supported extensively by measured data. Dynamic data sets include measurements from engine and surge test stands. The compressor model is further validated against a database of stationary compressor maps. The proposed model is shown to have good agreement with measured data for all regions, without the need for extensive geometric information or data.

Hydrogen pipeline compressors annual progress report.  

DOE Green Energy (OSTI)

The objectives are: (1) develop advanced materials and coatings for hydrogen pipeline compressors; (2) achieve greater reliability, greater efficiency, and lower capital in vestment and maintenance costs in hydrogen pipeline compressors; and (3) research existing and novel hydrogen compression technologies that can improve reliability, eliminate contamination, and reduce cost. Compressors are critical components used in the production and delivery of hydrogen. Current reciprocating compressors used for pipeline delivery of hydrogen are costly, are subject to excessive wear, have poor reliability, and often require the use of lubricants that can contaminate the hydrogen (used in fuel cells). Duplicate compressors may be required to assure availability. The primary objective of this project is to identify, and develop as required, advanced materials and coatings that can achieve the friction, wear, and reliability requirements for dynamically loaded components (seal and bearings) in high-temperature, high-pressure hydrogen environments prototypical of pipeline and forecourt compressor systems. The DOE Strategic Directions for Hydrogen Delivery Workshop identified critical needs in the development of advanced hydrogen compressors - notably, the need to minimize moving parts and to address wear through new designs (centrifugal, linear, guided rotor, and electrochemical) and improved compressor materials. The DOE is supporting several compressor design studies on hydrogen pipeline compression specifically addressing oil-free designs that demonstrate compression in the 0-500 psig to 800-1200 psig range with significant improvements in efficiency, contamination, and reliability/durability. One of the designs by Mohawk Innovative Technologies Inc. (MiTi{reg_sign}) involves using oil-free foil bearings and seals in a centrifual compressor, and MiTi{reg_sign} identified the development of bearings, seals, and oil-free tribological coatings as crucial to the successful development of an advanced compressor. MiTi{reg_sign} and ANL have developed potential coatings for these rigorous applications; however, the performance of these coatings (as well as the nickel-alloy substrates) in high-temperature, high-speed hydrogen environments is unknown at this point.

RELAP5-3D Compressor Model  

SciTech Connect

A compressor model has been implemented in the RELAP5-3D code. The model is similar to that of the existing pump model, and performs the same function on a gas as the pump performs on a single-phase or two-phase fluid. The compressor component consists of an inlet junction and a control volume, and optionally, an outlet junction. This feature permits cascading compressor components in series. The equations describing the physics of the compressor are derived from first principles. These equations are used to obtain the head, the torque, and the energy dissipation. Compressor performance is specified using a map, specific to the design of the machine, in terms of the ratio of outlet-to-inlet total (or stagnation) pressure and adiabatic efficiency as functions of rotational velocity and flow rate. The input quantities are specified in terms of dimensionless variables, which are corrected to stagnation density and stagnation sound speed. A small correction was formulated for the input of efficiency to account for the error introduced by assumption of constant density when integrating the momentum equation. Comparison of the results of steady-state operation of the compressor model to those of the MIT design calculation showed excellent agreement for both pressure ratio and power.

The State of the Industrial Compressor Market  

E-Print Network (OSTI)

The industrial compressor industry in the United States has been operating in a textbook example of a mature market. No truly new compressor technology has been introduced in the past thirty years and there is none on the horizon. Competitive pressures have pushed manufacturers to increase per-employee productivity and implement strict inventory and purchasing procedures to maintain profitability. Many major players that were in the rotary screw industry ten to fifteen years ago (Joy, Chicago Pneumatic, Worthington and Kellogg, to name a few) are gone. With Ingersoll-Rand's recent departure, Gardner Denver is the only U.S. company that manufactures an industrial, double-acting, reciprocating compressor. The dynamic compressor manufacturers face a similar situation. When inflation, small as it is, is factored in, industrial compressor prices have held steady or fallen in each of the past five years. With these market conditions, it is likely that the number of companies that manufacture industrial compressors will continue to decline. The companies that survive and grow will be the ones that offer solutions instead of just equipment.

Alternatives to compressor cooling in California climates  

SciTech Connect

This review and discussion has been prepared for the California Institute for Energy Efficiency (CIEE) to examine research on alternatives to compressor cooling. The report focuses on strategies for eliminating compressors in California's transition climates -- moderately warm areas located between the cool coastal regions and the hot central regions. Many of these strategies could also help reduce compressor use in hotter climates. Compressor-driven cooling of residences in California's transition climate regions is an undesirable load for California's electric utilities because load factor is poor and usage is typically high during periods of system peak demand. We review a number of alternatives to compressors, including low-energy strategies: evaporative cooling, natural and induced ventilation, reflective coatings, shading with vegetation and improved glazing, thermal storage, and radiative cooling. Also included are two energy-intensive strategies: absorption cooling and desiccant cooling. Our literature survey leads us to conclude that many of these strategies, used either singly or in combination, are technically and economically feasible alternatives to compressor-driven cooling. 78 refs., 8 figs.

Cycling Losses During Screw Air Compressor Operation  

E-Print Network (OSTI)

Air compressors use 10-13 % of a typical industrial facilities' total electricity. Because they often operate at part load, their part load efficiency significantly affects plant energy cost. An intensive study of screw air compressor part load efficiency confirmed that modulation only controls are accurately portrayed by traditional part load models under most conditions. It also confirmed that load-unload type controls are accurately modeled when cycle times are longer than 5 minutes. However, the study revealed compressors with cycling controls require as much as 10-25 % more power than is normally assumed when cycle times decrease below 2 minutes. This short cycle time is common in industrial environments. The study also found that combined modulating and unloading controls operate the compressor as much as 20% more efficiently than previously predicted. Several measures are recommended for improving part load efficiency by up to 25 %: Increase receiver capacity Install load-unload controls Maintain compressor controls Set higher low-unloading setpoints.

Assessment of Gas Turbine Compressor Health Monitoring Technologies: Interim Report  

Science Conference Proceedings (OSTI)

A major risk item in gas turbine machinery is compressor rotor/stator blade failure, which can lead to the downstream propagation of components through the compressor. Several events of this nature have occurred over the last few years, in some cases causing catastrophic damage to the entire compressor. In response to these issues, a number of compressor monitoring approaches have been proposed, with different degrees of commercial penetration and technological readiness. The simplest approach is to ...

The use of this method for adjustment of the grating compressor of a PEARL subpetawatt laser complex made it possible to align the diffraction gratings with a second accuracy in all three angular degrees of freedom, including alignment of the grooves, and to adjust the angles of beam incidence on the grating with a high accuracy. A simple method for measuring the difference in the groove densities of gratings with accuracy better than 0.005 lines mm{sup -1} is proposed and tested. (control of laser radiation parameters)

IMPROVEMENTS IN OR RELATING TO COMPRESSORS  

SciTech Connect

A compressor for fluids is designed with a rotary driving shaft and a labyrinth sealing gland. The gland incorporates a bleed pipe with a filtering device; any leakage in the gland results in a flow of fluid in the bleed pipe, and any filterable contaminants, e.g., oil or oil vapor, are removed. Easy access is provided to the motors (one of which is auxiliary) for maintenance and overhaul. This compressor design is especially applicable to gas-cooled reactors where coolant contamination must be avoided. (D.L.C.)

Method and apparatus for starting supersonic compressors  

DOE Patents (OSTI)

A supersonic gas compressor. The compressor includes aerodynamic duct(s) situated on a rotor journaled in a casing. The aerodynamic duct(s) generate a plurality of oblique shock waves for efficiently compressing a gas at supersonic conditions. The convergent inlet is adjacent to a bleed air collector, and during acceleration of the rotor, bypass gas is removed from the convergent inlet via a collector to enable supersonic shock stabilization. Once the oblique shocks are stabilized at a selected inlet relative Mach number and pressure ratio, the bleed of bypass gas from the convergent inlet via the bypass gas collectors is eliminated.

Market Opportunities for Electric Drive Compressors for Gas Transmission, Storage, and Processing  

E-Print Network (OSTI)

There is great interest in the large potential market for electric drives in the gas transmission, gas storage, and gas processing industries. Progressive electric utilities and astute vendors are moving to meet the needs of these industries as they confront rapid changes and new realities. New policy and economic considerations, brought on by changes in environmental and business regulations and new compressor/driver technology, are causing these gas industry companies to consider electric motors for replacement of older gas engines and for new compressor installations. In ozone nonattainment regions, bringing gas compressor stations into compliance with NOx emission regulations is a must. Outside those regions, new electric drives are being considered because of their improved operating efficiencies and lower costs. The Electric Power Research Institute (EPRI), working through the EPRI Chemicals and Petroleum Office, is providing leadership in the efforts to further dialogue among gas companies, electric utilities, and vendors. EN strategists is working closely with EPRI, the electric utilities, and the gas transmission companies to promote consideration of The Electric Option.

Compression station key to Texas pipeline project  

SciTech Connect

This was probably the largest pipeline project in the US last year, and the largest in Texas in the last decade. The new compressor station is a key element in this project. TECO, its servicing dealer, and compression packager worked closely throughout the planning and installation stages of the project. To handle the amount of gas required, TECO selected the GEMINI F604-1 compressor, a four-throw, single-stage unit with a six-inch stroke manufactured by Weatherford Enterra Compression Co. (WECC) in Corpus Christi, TX. TECO also chose WECC to package the compressors. Responsibility for ongoing support of the units will be shared among TECO, the service dealer and the packager. TECO is sending people to be trained by WECC, and because the G3600 family of engines is still relatively new, both the Caterpillar dealer and WECC sent people for advanced training at Caterpillar facilities in Peoria, IL. As part of its service commitment to TECO, the servicing dealer drew up a detailed product support plan, encompassing these five concerns: Training, tooling; parts support; service support; and commissioning.

Considerations in Dealing with the Risk of a Compressor Failure  

E-Print Network (OSTI)

Many plants do not have sufficient backup compressor capacity and risk having production outages due to compressor failures. Today, system designs are available that can eliminate this risk; however, there is a cost associated with doing so. In this article, we first point out why not every plant needs backup capacity and why those that do, do not always need to store sufficient air to carry the system through the start up of the backup compressor. Second, we discuss how personnel may be able to provide backup compressor capacity without installing another compressor and third, we discuss how to configure the system to reduce operating costs. Finally, we discuss how to reduce the required storage capacity needed to carry the system through the start up of the backup compressor.

IEMDC - In-Line Electric Motor Driven Compressor  

Science Conference Proceedings (OSTI)

This report covers the fifth quarter (01/01/04 to 03/31/04) of the In-Line Electric Motor Driven Compressor (IEMDC) project. Design efforts on the IEMDC continued with compressor efforts focused on performing aerodynamic analyses. These analyses were conducted using computational fluid dynamics. Compressor efforts also entailed developing mechanical designs of components through the use of solid models and working on project deliverables. Electric motor efforts focused on the design of the magnetic bearing system, motor pressure housing, and the motor-compressor interface. The mechanical evaluation of the main interface from both the perspective of the compressor manufacturer and electric motor manufacturer indicates that an acceptable design has been achieved. All mechanical and aerodynamic design efforts have resulted in considerable progress being made towards the completion of the compressor and electric motor design and towards the successful completion of the IEMDC unit.

Analysis and developpment of a Turbivo compressor for MRV applications  

E-Print Network (OSTI)

The mechanical vapor recompression is an efficient process to decrease energy consumption of drying processes. In order to use the mechanical vapor recompression (MVR) in residential clothe dryers, the volumetric Turbivo technology is used to design a dry water vapor compressor. The Turbivo volumetric machine is composed mainly of a rotor with one blade, a stator, and a mobile oscillating thrust. The advantages of Turbivo(R) technology are the absence of contact between rotor and stator as well as the oil-free operation. A model of the Turbivo compressor, including kinematic, dynamic, and thermodynamic analysis is presented. The compressor internal tightness is ensured by a surface treatment of the compressor components. Using the model, a water vapor Turbivo compressor of 12m3/h and compression ratio of 5 has been sized and realized. The compressor prototype will be tested on a dedicated test bench to characterize its volumetric and isentropic efficiencies.

An electric power generating plant includes at least two compressors having matched operating characteristics, alternators and turbines and boilers having combustion chambers connected to the turbines. The compressors, alternators and turbines are operatively interconnected such that during no power demand periods the compressors are driven in a series arrangement by the alternators, functioning as electric motors, to store a supply of pressurized air in an air storage tank, and during normal and peak power demand periods the turbines, supplied by the combustion chambers of the boilers, drive the compressors, functioning in parallel relationship, which feed respective ones of the boilers with enriched air and a gas recycled after expansion by one of the turbines. During the normal and peak power demand periods pressurized air previously stored in the air storage tank by the compressors is fed to the combustion chamber of one of the boilers.

Compressor & Steam Turbine Efficiency Improvements & Revamping Opportunities  

E-Print Network (OSTI)

Fossil fuels remain the dominant source for primary energy production worldwide. In relation to this trend, energy consumption in turbomachinery has been increasing due to the scale up of both the machinery itself as well as the processing plants in which they operate. This energy growth requires high efficiency improvements for machine design and operation to minimize life cycle cost. This paper will focus on the mechanical drive steam turbines which power the main process equipment in the heart of the plant and introduce the history of efficiency improvements for compressors and steam turbines in the Petrochemical Industry. Since heat balance configurations affect the plant's steam consumption, the authors will explain several cases of heat balance configurations and applications / selections of steam turbines. According to the change in output demand, in some cases the original plants are modified by increasing capacity and consequently the turbines and compressors are revamped internally or replaced totally. The authors will introduce several case studies on revamping to increase efficiency and reliability as per the following cases: a) Replacement of High Pressure Section Internals b) Replacement of Low Pressure Section Internals c) Replacement of All Internals d) Internals and Casing Replacement e) Efficiency Recovery Technique Modification Finally, life cycle cost (LCC) evaluation and sensitivity due to turbomachinery performance are explained as a case study of a mega ethylene plant.

Development of Inexpensive Turbo Compressor/Expanders for Industrial Use  

E-Print Network (OSTI)

Use of Turbo Compressor/ Expanders (TCEs) as industrial reversed Brayton Cycle Heat Pumps offers many technical and energy saving advantages. Until recently, such devices have been far too expensive in both capital cost and inefficiency mainly because the compressor and expander stages were built for forward Brayton Cycle operation in unmatched compressor/expander efficiencies. A few years ago, NUCON initiated a program to locate sources of TCEs and to engineer cost effective modifications to these standard TCEs for use in reverse Brayton Cycle condensation based pollution control and solvent recovery, material recycle applications. The NUCON program is continuing to further improve the matched compressor/expander efficiency, the availability and cost effectiveness of these uses. This program has resulted in major advances in availability and significant improvements in efficiency.

Natural Gas Compressor for Residential Use ---- Inventor Robert Cutler Natural Gas Compressor for Residential Use ---- Inventor Robert Cutler This invention disclosure describes a system for gas compression to ultra-high pressures, which is required in many industrial and automotive processes. Gas compression, to pressures above about 100 psig, generally requires cooling to remove heat of compression and may require many stages of compression for efficient operation. Also most piston-type compressors require lubrication between the piston and cylinder, and lubricant may be entrained in the compressed gas, thereby requiring efficient oil removal means downstream of the compressor. This invention describes a system that addresses these requirements in a cost effective system suitable for residential and light industrial applications.

Development of a high-specific-speed centrifugal compressor  

SciTech Connect

This paper describes the development of a subscale single-stage centrifugal compressor with a dimensionless specific speed (Ns) of 1.8, originally designed for full-size application as a high volume flow, low pressure ratio, gas booster compressor. The specific stage is noteworthy in that it provides a benchmark representing the performance potential of very high-specific-speed compressors, of which limited information is found in the open literature. Stage and component test performance characteristics are presented together with traverse results at the impeller exit. Traverse test results were compared with recent CFD computational predictions for an exploratory analytical calibration of a very high-specific-speed impeller geometry. The tested subscale (0.583) compressor essentially satisfied design performance expectations with an overall stage efficiency of 74% including, excessive exit casing losses. It was estimated that stage efficiency could be increased to 81% with exit casing losses halved.

Hyper dispersion pulse compressor for chirped pulse amplification systems  

Science Conference Proceedings (OSTI)

A grating pulse compressor configuration is introduced for increasing the optical dispersion for a given footprint and to make practical the application for chirped pulse amplification (CPA) to quasi-narrow bandwidth materials, such as Nd:YAG. The grating configurations often use cascaded pairs of gratings to increase angular dispersion an order of magnitude or more. Increased angular dispersion allows for decreased grating separation and a smaller compressor footprint.

Axial inlet conversion to a centrifugal compressor with magnetic bearings  

Science Conference Proceedings (OSTI)

NOVA's Alberta Gas Transmission Division transports natural gas via pipeline throughout the province of Alberta, Canada, exporting it to eastern Canada, US, and British Columbia. There is a continuing effort to operate the facilities and pipeline at the highest possible efficiency. One area being addressed to improve efficiency is compression of the gas. By improving compressor efficiency, fuel consumption and hence operating costs can be reduced. One method of improving compressor efficiency is by converting the compressor to an axial inlet configuration, a conversion that has been carried out more frequently in the past years. Concurrently, conventional hydrodynamic bearings have been replaced with magnetic bearings on many centrifugal compressors. This paper discusses the design and installation for converting a radial overhung unit to an axial inlet configuration, having both magnetic bearings and a thrust reducer. The thrust reducer is required to reduce axial compressor shaft loads, to a level that allows the practical installation of magnetic bearings within the space limitations of the compressor (Bear and Gibson, 1992).

Conserve Energy by Optimizing Air Compressor System  

E-Print Network (OSTI)

There are many opportunities to conserve energy within an Industrial Plant without adversely impacting the operation or production. Many of these represent only relatively small savings, when compared to the overall utility bill; however, one major benefit of energy conservation is that the resultant savings in dollars goes directly to the bottom line as increased profits. To generate the same amount of profit dollars as an effective energy conservation project can generate, in cost avoidance, the plant would have to substantially increase the product shipments. This is not always possible; however, conserving energy is nearly always possible. How should one begin an energy conservation program within a major Industrial Plant? The same as any other taskone step at a time. This paper addresses one of the many small projects available within many industriesthe plant air compressing systems. It outlines how one industrial plant was able to reduce the utility bill by approximately $50,000 per year just within the compressor plant alone.

Downhole steam generator having a downhole oxidant compressor  

SciTech Connect

Apparatus and method for generation of steam in a borehole for penetration into an earth formation wherein a downhole oxidant compressor is used to compress relatively low pressure (atmospheric) oxidant, such as air, to a relatively high pressure prior to mixing with fuel for combustion. The multi-stage compressor receives motive power through a shaft driven by a gas turbine powered by the hot expanding combustion gases. The main flow of compressed oxidant passes through a velocity increasing nozzle formed by a reduced central section of the compressor housing. An oxidant bypass feedpipe leading to peripheral oxidant injection nozzles of the combustion chamber are also provided. The downhole compressor allows effective steam generation in deep wells without need for high pressure surface compressors. Feedback preheater means are provided for preheating fuel in a preheat chamber. Preheating of the water occurs in both a water feed line running from aboveground and in a countercurrent water flow channel surrounding the combustor assembly. The countercurrent water flow channels advantageously serve to cool the combustion chamber wall. The water is injected through slotted inlets along the combustion chamber wall to provide an unstable boundary layer and stripping of the water from the wall for efficient steam generation. Pressure responsive doors are provided at the steam outlet for closing and sealing the combustion chamber from entry of reservoir fluids in the event of a flameout.

Metering Air Compressor Systems for Efficiency: A Progress Report  

E-Print Network (OSTI)

Air compressors have energy efficiency quantified as SCFM/BHP. However, this efficiency fluctuates over a broad range based on the loading of the compressor. When multiple compressors operate with varying loads, as in a central plant, the overall system efficiency is totally unknown. With funding from California Energy Commission under the PIER Program, we spent considerable effort over the past few years to develop system efficiency for air compressor central plants. The system efficiency was termed CASE Index, which varies from 0 to about 320, and has the units of SCF/KWH. The procedure we developed, involved metering of input (KWH) and output (SCFM), in and out of the central plant. After the initial beta testing of the procedure, as more and more compressor professionals started to use the procedure and as more metering equipments entered the picture, some metering complications were encountered. These problems were dealt with and the procedure developed under this project can produce reliable data. This paper also presents the system efficiencies we have recorded so far and the opportunities they indicate. The data shows a wide range, from a low 82 to about 250 on a 0 to 320 scale. This confirms our expectations of large energy efficiency improvement potential in compressed air systems.

Development of an Electrochemical Separator and Compressor  

DOE Green Energy (OSTI)

Global conversion to sustainable energy is likely to result in a hydrogen-based economy that supports U.S. energy security objectives while simultaneously avoiding harmful carbon emissions. A key hurdle to successful implementation of a hydrogen economy is the low-cost generation, storage, and distribution of hydrogen. One of the most difficult requirements of this transformation is achieving economical, high density hydrogen storage in passenger vehicles. Transportation applications may require compression and storage of high purity hydrogen up to 12,000 psi. Hydrogen production choices range from centralized low-pressure generation of relatively impure gas in large quantities from steam-methane reformer plants to distributed generation of hydrogen under moderate pressure using water electrolysis. The Electrochemical Hydrogen Separator + Compressor (EHS+C) technology separates hydrogen from impurities and then compresses it to high pressure without any moving parts. The Phase I effort resulted in the construction and demonstration of a laboratory-scale hardware that can separate and compress hydrogen from reformate streams. The completion of Phase I has demonstrated at the laboratory scale the efficient separation and compression of hydrogen in a cost effective manner. This was achieved by optimizing the design of the Electrochemical Hydrogen Compression (EHC) cell hardware and verified by parametric testing in single cell hardware. A broad range of commercial applications exist for reclamation of hydrogen. One use this technology would be in combination with commercial fuel cells resulting in a source of clean power, heat, and compressed hydrogen. Other applications include the reclamation of hydrogen from power plants and other industrial equipment where it is used for cooling, recovery of process hydrogen from heat treating processes, and semiconductor fabrication lines. Hydrogen can also be recovered from reformate streams and cryogenic boil-offs using this technology.

IEMDC -IN-LINE ELECTRIC MOTOR DRIVEN COMPRESSOR  

SciTech Connect

Dresser-Rand completed the preliminary aerodynamic flowpath of the volute and inlet design for the compressor section. This has resulted in considerable progress being made on the development of the compressor section and ultimately towards the successful integration of the IEMDC System design. Significant effort was put forth in the design of aerodynamic components which resulted in a design that meets the limits of aerodynamically induced radial forces previously established. Substantial effort has begun on the mechanical design of the compressor pressure containing case and other internal components. These efforts show progression towards the successful integration of a centrifugal compressor and variable speed electric motor ventilated by the process gas. All efforts continue to confirm the feasibility of the IEMDC system design. During the third quarter reporting period, the focus was to further refine the motor design and to ensure that the IEMDC rotor system supported on magnetic bearing is in compliance with the critical speed and vibration requirements of the API standards 617 and 541. Consequently specification to design magnetic bearings was developed and an RFQ to three magnetic bearing suppliers was issued. Considerable work was also performed to complete preliminary reports on some of the deliverable tasks under phase 1.0. These include specification for the VFD, RFQ for the magnetic bearings, and preliminary write-up for motor instrumentation and control schematic. In order to estimate motor efficiency at various operating points, plots of calculated motor losses, and motor cooling gas flow rates were also prepared. Preliminary evaluations of motor support concepts were performed via FEA to determine modal frequencies. Presentation was made at DOE Morgantown on August 12, 2003 to provide project status update. Preparations for the IEMDC motor-compressor presentation, at the GMRC conference in Salt Lake City to be held on October 5, 2003, were also started. Detailed calculations of cooling gas flow requirements for the motor and magnetic bearings, per several new operating points designated by DR, confirmed that the required gas flow was within the compressor design guidelines. Previous thrust load calculations had confirmed that the magnetic thrust bearing design load capacity of 6,000 lb. was sufficient to handle the net thrust load produced by the motor and compressor pressure loading. Thus the design data that has been generated, for the variable speed 10 MW 12,000 rpm motor, during the last three quarters, continue to confirm the feasibility of an efficient and robust motor design.

High Technology Centrifugal Compressor for Commercial Air Conditioning Systems  

Science Conference Proceedings (OSTI)

R&D Dynamics, Bloomfield, CT in partnership with the State of Connecticut has been developing a high technology, oil-free, energy-efficient centrifugal compressor called CENVA for commercial air conditioning systems under a program funded by the US Department of Energy. The CENVA compressor applies the foil bearing technology used in all modern aircraft, civil and military, air conditioning systems. The CENVA compressor will enhance the efficiency of water and air cooled chillers, packaged roof top units, and other air conditioning systems by providing an 18% reduction in energy consumption in the unit capacity range of 25 to 350 tons of refrigeration The technical approach for CENVA involved the design and development of a high-speed, oil-free foil gas bearing-supported two-stage centrifugal compressor, CENVA encompassed the following high technologies, which are not currently utilized in commercial air conditioning systems: Foil gas bearings operating in HFC-134a; Efficient centrifugal impellers and diffusers; High speed motors and drives; and System integration of above technologies. Extensive design, development and testing efforts were carried out. Significant accomplishments achieved under this program are: (1) A total of 26 builds and over 200 tests were successfully completed with successively improved designs; (2) Use of foil gas bearings in refrigerant R134a was successfully proven; (3) A high speed, high power permanent magnet motor was developed; (4) An encoder was used for signal feedback between motor and controller. Due to temperature limitations of the encoder, the compressor could not operate at higher speed and in turn at higher pressure. In order to alleviate this problem a unique sensorless controller was developed; (5) This controller has successfully been tested as stand alone; however, it has not yet been integrated and tested as a system; (6) The compressor successfully operated at water cooled condensing temperatures Due to temperature limitations of the encoder, it could not be operated at air cooled condensing temperatures. (7) The two-stage impellers/diffusers worked well separately but combined did not match well.

IEMDC IN-LINE ELECTRIC MOTOR DRIVEN COMPRESSOR  

SciTech Connect

This report contains the final project summary and deliverables required by the award for the development of an In-line Electric Motor Driven Compressor (IEMDC). Extensive work was undertaken during the course of the project to develop the motor and the compressor section of the IEMDC unit. Multiple design iterations were performed to design an electric motor for operation in a natural gas environment and to successfully integrate the motor with a compressor. During the project execution, many challenges were successfully overcome in order to achieve the project goals and to maintain the system design integrity. Some of the challenges included limiting the magnitude of the compressor aerodynamic loading for appropriate sizing of the magnetic bearings, achieving a compact motor rotor size to meet the rotor dynamic requirements of API standards, devising a motor cooling scheme using high pressure natural gas, minimizing the impact of cooling on system efficiency, and balancing the system thrust loads for the magnetic thrust bearing. Design methods that were used on the project included validated state-of-the-art techniques such as finite element analysis and computational fluid dynamics along with the combined expertise of both Curtiss-Wright Electro-Mechanical Corporation and Dresser-Rand Company. One of the most significant areas of work undertaken on the project was the development of the unit configuration for the system. Determining the configuration of the unit was a significant step in achieving integration of the electric motor into a totally enclosed compression system. Product review of the IEMDC unit configuration was performed during the course of the development process; this led to an alternate design configuration. The alternate configuration is a modular design with the electric motor and compressor section each being primarily contained in its own pressure containing case. This new concept resolved the previous conflict between the aerodynamic flow passage requirements and electric motor requirements for support and utilities by bounding the flowpath within the compressor section. However most importantly, the benefits delivered by the new design remained the same as those proposed by the goals of the project. In addition, this alternate configuration resulted in the achievement of a few additional advantages over the original concept such as easier maintenance, operation, and installation. Interaction and feedback solicited from target clients regarding the unit configuration supports the fact that the design addresses industry issues regarding accessibility, maintainability, preferred operating practice, and increased reliability.

Turbine inter-disk cavity cooling air compressor  

DOE Patents (OSTI)

A combustion turbine may have a cooling circuit for directing a cooling medium through the combustion turbine to cool various components of the combustion turbine. This cooling circuit may include a compressor, a combustor shell and a component of the combustion turbine to be cooled. This component may be a rotating blade of the combustion turbine. A pressure changing mechanism is disposed in the combustion turbine between the component to be cooled and the combustor shell. The cooling medium preferably flows from the compressor to the combustor shell, through a cooler, the component to the cooled and the pressure changing mechanism. After flowing through the pressure changing mechanism, the cooling medium is returned to the combustor shell. The pressure changing mechanism preferably changes the pressure of the cooling medium from a pressure at which it is exhausted from the component to be cooled to approximately that of the combustor shell.

Personnel in the Instrumentation and Controls Division at the Oak Ridge National Laboratory, in association with the United States Enrichment corporation (USEC), the Navy, and various Department of Energy sponsors, have been involved in the development and application of motor-current signature analysis (CSA) for several years. In that time CSA has proven to not only be useful for manually applied periodic monitoring of electrically driven equipment but it has also been demonstrated to be well suited for dedicated monitoring systems in industrial settings. Recent work has resulted in the development and installation of a system that can monitor up to 640 motor and compressor stages for various aerodynamic conditions in the gas compressors and electrical problems in the drive motors. This report describes a demonstration of that technology installed on 80 stages at each of the two USEC uranium enrichment plants.

A helium cryogenic compressor was developed and tested in real conditions in 1996. The achieved objective was to compress 0.018 kg/s Helium at 4 K @ 1000 Pa (10 mbar) up to 3000 Pa (30 mbar). This project was an opportunity to develop and test an interesting new concept in view of future needs. The main features of this new specific technology are described. Particular attention is paid to the gas bearing supported rotor and to the pneumatic driver. Trade off between existing technologies and the present work are presented with special stress on the bearing system and the driver. The advantages are discussed, essentially focused on life time and high reliability without maintenance as well as non pollution characteristic. Practical operational modes are also described together with the experimental performances of the compressor. The article concludes with a brief outlook of future work.

Constructions of fault tolerant linear compressors and linear decompressors  

E-Print Network (OSTI)

Abstract The constructions of optical buffers is one of the most critically sought after optical technologies in all-optical packet-switched networks, and constructing optical buffers directly via optical Switches and fiber Delay Lines (SDL) has received a lot of attention recently in the literature. A practical and challenging issue of the constructions of optical buffers that has not been addressed before is on the fault tolerant capability of such constructions. In this paper, we focus on the constructions of fault tolerant linear compressors and linear decompressors. The basic network element for our constructions is scaled optical memory cell, which is constructed by a 2 2 optical crossbar switch and a fiber delay line. We give a multistage construction of a self-routing linear compressor by a concatenation of scaled optical memory cells. We also show that if the delays, say d1, d2,..., dM, of the fibers in the scaled optical memory cells satisfy a certain condition (specifically, the condition in (A2) given in Section I), then our multistage construction can be operated as a self-routing linear compressor with maximum delay ? M?F even after up to F of the M scaled optical memory cells fail to function properly, where 0 ? F ? M ? 1. Furthermore, we prove that our multistage construction with the fiber delays d1, d2,..., dM given by the generalized Fibonacci series of order F is the best among all constructions of a linear compressor that can tolerate up to F faulty scaled optical memory cells by using M scaled optical memory cells.

Turbine inter-disk cavity cooling air compressor  

DOE Patents (OSTI)

The inter-disk cavity between turbine rotor disks is used to pressurize cooling air. A plurality of ridges extend radially outwardly over the face of the rotor disks. When the rotor disks are rotated, the ridges cause the inter-disk cavity to compress air coolant flowing through the inter-disk cavity en route to the rotor blades. The ridges eliminate the need for an external compressor to pressurize the air coolant.

Dual capacity compressor with reversible motor and controls arrangement therefor  

DOE Patents (OSTI)

A hermetic reciprocating compressor such as may be used in heat pump applications is provided for dual capacity operation by providing the crankpin of the crankshaft with an eccentric ring rotatably mounted thereon, and with the end of the connecting rod opposite the piston encompassing the outer circumference of the eccentric ring, with means limiting the rotation of the eccentric ring upon the crankpin between one end point and an opposite angularly displaced end point to provide different values of eccentricity depending upon which end point the eccentric ring is rotated to upon the crankpin, and a reversible motor in the hermetic shell of the compressor for rotating the crankshaft, the motor operating in one direction effecting the angular displacement of the eccentric ring relative to the crankpin to the one end point, and in the opposite direction effecting the angular displacement of the eccentric ring relative to the crankpin to the opposite end point, this arrangement automatically giving different stroke lengths depending upon the direction of motor rotation. The mechanical structure of the arrangement may take various forms including at least one in which any impact of reversal is reduced by utilizing lubricant passages and chambers at the interface area of the crankpin and eccentric ring to provide a dashpot effect. In the main intended application of the arrangement according to the invention, that is, in a refrigerating or air conditioning system, it is desirable to insure a delay during reversal of the direction of compressor operation. A control arrangement is provided in which the control system controls the direction of motor operation in accordance with temperature conditions, the system including control means for effecting operation in a low capacity direction or alternatively in a high capacity direction in response to one set, and another set, respectively, of temperature conditions and with timer means delaying a restart of the compressor motor for at least a predetermined time in response to a condition of the control means operative to initiate a change in the operating direction of the compressor when it restarts.

IMPROVEMENT TO PIPELINE COMPRESSOR ENGINE RELIABILITY THROUGH RETROFIT MICRO-PILOT IGNITION SYSTEM -- PHASE III  

Science Conference Proceedings (OSTI)

This report documents the third year's effort towards a 3-year program conducted by the Engines & Energy Conversion Laboratory (EECL) at Colorado State University (CSU) to develop micropilot ignition systems for existing pipeline compressor engines. Research activities for the overall program were conducted with the understanding that the efforts are to result in a commercial product to capture and disseminate the efficiency and environmental benefits of this new technology. Commercially-available fuel injection products were identified and applied to the program where appropriate. This approach will minimize the overall time-to-market requirements, while meeting performance and cost criteria. Two earlier phases of development precede this report. The objective for Phase I was to demonstrate the feasibility of retrofit micropilot ignition (RMI) systems for large bore, slow speed engines operating at low compression ratios under laboratory conditions at the EECL. The objective for Phase II was to further develop and optimize the micropilot ignition system at the EECL for large bore, slow speed engines operating at low compression ratios. These laboratory results were enhanced, then verified via a field demonstration project during Phase III of the Micropilot Ignition program. An Implementation Team of qualified engine retrofit service providers was assembled to install the retrofit micropilot ignition system for an engine operated by El Paso Pipeline Group at a compressor station near Window Rock, Arizona. Testing of this demonstration unit showed that the same benefits identified by laboratory testing at CSU, i.e., reduced fuel consumption and exhaust emissions (NOx, THC, CO, and CH2O). Installation efforts at Window Rock were completed towards the end of the budget period, which did not leave sufficient time to complete the durability testing. These efforts are ongoing, with funding provided by El Paso Pipeline Group, and the results will be documented in a report. Commercialization of the retrofit micropilot ignition (RMI) technology is awaiting a ''market pull'', which is expected to materialize as the results of the field demonstration become known and accepted. The Implementation Team, comprised of Woodward Governor Company, Enginuity LLC, Hoerbiger Corporation of America, and DigiCon Inc., has direct experience with the technology development and implementation, and stands ready to promote and commercialize the RMI system.

Arbitrary surface flank milling of fan, compressor, and impeller blades  

SciTech Connect

It is generally conceived that a blade surface is flank millable if it can be closely approximated by a ruled surface; otherwise the slow machining process of point milling has to be employed. However, the authors have now demonstrated that the ruled surface criterion for flank milling is neither necessary nor sufficient. Furthermore, many complex arbitrary surfaces typical of the blades in fans, axial compressors, and centrifugal impellers in aviation gas turbines are actually closely flank millable and can be rendered exactly flank millable with one or more passes per surface often without sacrificing, indeed usually with gain, in performance.

Observations of internal relaxation oscillations in the adiabatic toroidal compressor  

SciTech Connect

The soft x ray signal from the Adiabatic Toroidal compressor (ATC) sometimes exhibits a 10 percent modulation with a frequency between 1 and 2 Kilohertz. The radial profile of the soft x ray signal and the electron temperature determined by laser scattering indicate that these fluctuations are associated with a limitation of the central electron temperature and a broadening of the temperature profile. By observing changes in the radial dependence of the relaxation oscillation during neutral injection, an increase of thirty to fifty percent in the radius where q = 1 was measured. (auth)

Experiments and modelling of surge in small centrifugal compressor for automotive engines  

SciTech Connect

In this paper the surge phenomenon in small centrifugal compressors used for turbocharging internal combustion engines is analyzed. The experimental work was focused on the measurement of compressor behaviour within the surge zone by means of a specifically designed facility. The presented model is based on the introduction of a fluid inertia term that accounts for the non quasi steady effects and the use of a compressor map extended to the surge and negative flows zone obtained from experimental tests. The compressor model was implemented in a one-dimensional gas-dynamic model. The comparison of the modelled and measured evolution of instantaneous pressure during deep surge operation shows good agreement. Furthermore, the model is also able to predict the amplitude and frequency of pressure pulses when the compressor operates in surge with different outlet duct lengths. (author)

Hydrogen Filling Station  

SciTech Connect

Hydrogen is an environmentally attractive transportation fuel that has the potential to displace fossil fuels. The Freedom CAR and Freedom FUEL initiatives emphasize the importance of hydrogen as a future transportation fuel. Presently, Las Vegas has one hydrogen fueling station powered by natural gas. However, the use of traditional sources of energy to produce hydrogen does not maximize the benefit. The hydrogen fueling station developed under this grant used electrolysis units and solar energy to produce hydrogen fuel. Water and electricity are furnished to the unit and the output is hydrogen and oxygen. Three vehicles were converted to utilize the hydrogen produced at the station. The vehicles were all equipped with different types of technologies. The vehicles were used in the day-to-day operation of the Las Vegas Valley Water District and monitoring was performed on efficiency, reliability and maintenance requirements. The research and demonstration utilized for the reconfiguration of these vehicles could lead to new technologies in vehicle development that could make hydrogen-fueled vehicles more cost effective, economical, efficient and more widely used. In order to advance the development of a hydrogen future in Southern Nevada, project partners recognized a need to bring various entities involved in hydrogen development and deployment together as a means of sharing knowledge and eliminating duplication of efforts. A road-mapping session was held in Las Vegas in June 2006. The Nevada State Energy Office, representatives from DOE, DOE contractors and LANL, NETL, NREL were present. Leadership from the National hydrogen Association Board of Directors also attended. As a result of this session, a roadmap for hydrogen development was created. This roadmap has the ability to become a tool for use by other road-mapping efforts in the hydrogen community. It could also become a standard template for other states or even countries to approach planning for a hydrogen future. Project partners also conducted a workshop on hydrogen safety and permitting. This provided an opportunity for the various permitting agencies and end users to gather to share experiences and knowledge. As a result of this workshop, the permitting process for the hydrogen filling station on the Las Vegas Valley Water Districts land was done more efficiently and those who would be responsible for the operation were better educated on the safety and reliability of hydrogen production and storage. The lessons learned in permitting the filling station and conducting this workshop provided a basis for future hydrogen projects in the region. Continuing efforts to increase the working pressure of electrolysis and efficiency have been pursued. Research was also performed on improving the cost, efficiency and durability of Proton Exchange Membrane (PEM) hydrogen technology. Research elements focused upon PEM membranes, electrodes/catalysts, membrane-electrode assemblies, seals, bipolar plates, utilization of renewable power, reliability issues, scale, and advanced conversion topics. Additionally, direct solar-to-hydrogen conversion research to demonstrate stable and efficient photoelectrochemistry (PEC) hydrogen production systems based on a number of optional concepts was performed. Candidate PEC concepts included technical obstacles such as inefficient photocatalysis, inadequate photocurrent due to non-optimal material band gap energies, rapid electron-hole recombination, reduced hole mobility and diminished operational lifetimes of surface materials exposed to electrolytes. Project Objective 1: Design, build, operate hydrogen filling station Project Objective 2: Perform research and development for utilizing solar technologies on the hydrogen filling station and convert two utility vehicles for use by the station operators Project Objective 3: Increase capacity of hydrogen filling station; add additional vehicle; conduct safety workshop; develop a roadmap for hydrogen development; accelerate the development of photovoltaic components Project Objective 4:

Numerical simulation of the impeller tip clearance effect on centrifugal compressor performance  

E-Print Network (OSTI)

This thesis presents the numerical simulation of flow in centrifugal compressors. A three-dimensional Navier-Stokes solver was employed to simulate flow through two centrifugal compressors. The first compressor simulated was the NASA low speed centrifugal compressor (LSCC). The LSCC was selected as a test compressor because of the experimental data available. The numerically simulated data was compared to the experimental data to validate the flow solver. The numerical results were in good agreement with the experimental. The second compressor simulated was a Honeywell turbopump centrifugal compressor (HCC). The HCC was simulated for three tip clearances at six wheel speeds. Six operating conditions were investigated at each tip clearance and wheel speed. The data obtained from the HCC simulations was used to investigate the effect of tip clearance on compressor performance. Specifically, the total-total pressure ratio, mass flow rate and adiabatic efficiencies were tracked to see how each were affected by an increasing tip clearance. The results show that as the tip clearance was increased, the total-total pressure ratio, mass flow rate and adiabatic efficiencies all decreased for the same static-total pressure ratio. The pressure differences and temperature differences, from the pressure side to the suction side of the blade, and the vorticity were all explored as possible causes of this reduced performance. The pressure proved to be the biggest impactor on performance. The increased tip clearance let more flow leak across the blade tip. The leakage flow tried to homogenize the pressure difference across the blade. The overall effect resulted in a much lower pressure difference. The temperature remained nearly the same as the tip clearance increased. The vorticity increased, but this was also a result of the increased tip leakage flow. To aid in total-total pressure ratio predictions, the results for the HCC were put into compressor maps.

Hydraulic accumulator-compressor for geopressured enhanced oil recovery  

DOE Patents (OSTI)

A hydraulic accumulator-compressor vessel using geothermal brine under pressure as a piston to compress waste (CO.sub.2 rich) gas is used in a system having a plurality of gas separators in tandem to recover pipeline quality gas from geothermal brine. A first high pressure separator feeds gas to a membrance separator which separates low pressure waste gas from high pressure quality gas. A second separator produces low pressure waste gas. Waste gas from both separators is combined and fed into the vessel through a port at the top as the vessel is drained for another compression cycle. High pressure brine is then admitted into the vessel through a port at the bottom of the vessel. Check valves control the flow of low pressure waste gas into the vessel and high pressure waste gas out of the vessel.

Detailed stress tensor measurements in a centrifugal compressor vaneless diffuser  

Science Conference Proceedings (OSTI)

Detailed flow measurements have been made in the vaneless diffuser of a large low-speed centrifugal compressor using hot-wire anemometry. The three time mean velocity components and full stress tensor distributions have been determined on eight measurement plans within the diffuser. High levels of Reynolds stress result in the rapid mixing out of the blade wake. Although high levels of turbulent kinetic energy are found in the passage wake, they are not associated with strong Reynolds stresses and hence the passage wake mixes out only slowly. Low-frequency meandering of the wake position is therefore likely to be responsible for the high kinetic energy levels. The anisotropic nature of the turbulence suggests that Reynolds stress turbulence models are required for CFD modeling of diffuser flows.

Refrigeration system with a compressor-pump unit and a liquid-injection desuperheating line  

DOE Patents (OSTI)

The refrigeration system includes a compressor-pump unit and/or a liquid-injection assembly. The refrigeration system is a vapor-compression refrigeration system that includes an expansion device, an evaporator, a compressor, a condenser, and a liquid pump between the condenser and the expansion device. The liquid pump improves efficiency of the refrigeration system by increasing the pressure of, thus subcooling, the liquid refrigerant delivered from the condenser to the expansion device. The liquid pump and the compressor are driven by a single driving device and, in this regard, are coupled to a single shaft of a driving device, such as a belt-drive, an engine, or an electric motor. While the driving device may be separately contained, in a preferred embodiment, the liquid pump, the compressor, and the driving device (i.e., an electric motor) are contained within a single sealable housing having pump and driving device cooling paths to subcool liquid refrigerant discharged from the liquid pump and to control the operating temperature of the driving device. In another aspect of the present invention, a liquid injection assembly is included in a refrigeration system to divert liquid refrigerant from the discharge of a liquid pressure amplification pump to a compressor discharge pathway within a compressor housing to desuperheat refrigerant vapor to the saturation point within the compressor housing. The liquid injection assembly includes a liquid injection pipe with a control valve to meter the volume of diverted liquid refrigerant. The liquid injection assembly may also include a feedback controller with a microprocessor responsive to a pressure sensor and a temperature sensor both positioned between the compressor to operate the control valve to maintain the refrigerant at or near saturation.

Compressor and Turbine Models of Brayton Units for Space Nuclear Power Systems  

SciTech Connect

Closed Brayton Cycles with centrifugal flow, single-shaft turbo-machines are being considered, with gas cooled nuclear reactors, to provide 10's to 100's of electrical power to support future space exploration missions and Lunar and Mars outposts. Such power system analysis is typically based on the cycle thermodynamics, for given operating pressures and temperatures and assumed polytropic efficiencies of the compressor and turbine of the Brayton energy conversion units. Thus the analysis results not suitable for modeling operation transients such as startup and changes in the electric load. To simulate these transients, accurate models of the turbine and compressor in the Brayton rotating unit, which calculate the changes in the compressor and turbine efficiencies with system operation are needed. This paper presents flow models that account for the design and dimensions of the compressor impeller and diffuser, and the turbine stator and rotor blades. These models calculate the various enthalpy losses and the polytropic efficiencies along with the pressure ratios of the turbine and compressor. The predictions of these models compare well with reported performance data of actual hardware. In addition, the results of a parametric analysis to map the operations of the compressor and turbine, as functions of the rotating shaft speed and inlet Mach number of the gas working fluid, are presented and discussed. The analysis used a binary mixture of He-Xe with a molecular weight of 40 g/mole as the working fluid.

FrAT2.4 Introducing Back-up to Active Compressor Surge Control System ?  

E-Print Network (OSTI)

Abstract: A novel method for introducing a back-up system to an active compressor surge control system is presented in this paper. Active surge control is a promising method for extending the compressor map towards and into the unstable area at low mass flow by stabilizing the surge phenomenon. The method also has potential for allowing operation at higher efficiencies. However, a failure in the active surge control system may endanger the compressor by entering deep surge as the compressor is allowed to operate in the stabilized surge area. We propose the use of a back-up system applied to the active system to keep the compressor safe should the active system fail. This paper present an active compressor surge control system with piston actuation combined with a blow off system as the back-up. Performance of the combined system is evaluated by simulating the system in situations where the piston is saturated or jammed. The combination results in a system with increased performance by taking advantage of both systems.

Compressor performance at high suction temperatures with application to solar heat pump  

DOE Green Energy (OSTI)

As part of the study of Solar Assisted Heat Pump (SAHP) Systems, the performance of the heat pump itself and its components under conditions attendant to series solar input to the evaporator is being investigated at Brookhaven National Laboratory (BNL). Particular emphasis has been placed on the details of the compressor performance, since in order to properly exploit the thermodynamic potential of high solar input temperatures (40 to 100/sup 0/F), the compressor must operate efficiently over a wide range of (saturated) suction temperatures most of which are well above those for which present compressors are designed. A systematic series of experiments is being conducted at evaporating temperatures in the range from 45 to 100/sup 0/F using a Solar Heat Pump Simulator and a specially designed Laboratory Model Heat Pump assembled from off-the-shelf components. Two reciprocating compressors have been tested thus far - an open type driven by a 2-speed motor and a hermetic 2-speed, the multi-speed feature providing capacity control, which is a virtual necessity for effective use of solar source. Thorough and highly accurate instrumentation is used in the simulator and in the heat pump refrigeration loop. The results to date of the compressor aspects of the solar heat pump experiments at BNL are described, and the general application of heat pumps and their compressors to use with solar input are discussed.

Apparatus and methods for cooling and sealing rotary helical screw compressors  

DOE Patents (OSTI)

In a compression system which incorporates a rotary helical screw compressor, and for any type of gas or refrigerant, the working liquid oil is atomized through nozzles suspended in, and parallel to, the suction gas flow, or alternatively the nozzles are mounted on the suction piping. In either case, the aim is to create positively a homogeneous mixture of oil droplets to maximize the effectiveness of the working liquid oil in improving the isothermal and volumetric efficiencies. The oil stream to be atomized may first be degassed at compressor discharge pressure by heating within a pressure vessel and recovering the energy added by using the outgoing oil stream to heat the incoming oil stream. The stripped gas is typically returned to the compressor discharge flow. In the preferred case, the compressor rotors both contain a hollow cavity through which working liquid oil is injected into channels along the edges of the rotors, thereby forming a continuous and positive seal between the rotor edges and the compressor casing. In the alternative method, working liquid oil is injected either in the same direction as the rotor rotation or counter to rotor rotation through channels in the compressor casing which are tangential to the rotor edges and parallel to the rotor center lines or alternatively the channel paths coincide with the helical path of the rotor edges. 14 figs.

IMPROVEMENT TO PIPELINE COMPRESSOR ENGINE RELIABILITY THROUGH RETROFIT MICRO-PILOT IGNITION SYSTEM  

Science Conference Proceedings (OSTI)

This report documents a 3-year research program conducted by the Engines & Energy Conversion Laboratory (EECL) at Colorado State University (CSU) to develop micropilot ignition systems for existing pipeline compressor engines. Research activities for the overall program were conducted with the understanding that the efforts are to result in a commercial product to capture and disseminate the efficiency and environmental benefits of this new technology. An extensive state-of-art review was conducted to leverage the existing body of knowledge of micropilot ignition with respect to retrofit applications. Additionally, commercially-available fuel injection products were identified and applied to the program where appropriate. This approach will minimize the overall time-to-market requirements, while meeting performance and cost criteria. The objective for Phase I was to demonstrate the feasibility of micropilot ignition for large bore, slow speed engines operating at low compression ratios under laboratory conditions at the EECL. The primary elements of Micropilot Phase I were to develop a single-cylinder test chamber to study the injection of pilot fuel into a combustion cylinder and to develop, install and test a multi-cylinder micropilot ignition system for a 4-cylinder, natural gas test engine. In all, there were twelve (12) tasks defined and executed to support these two (2) primarily elements in a stepwise fashion. Task-specific approaches and results are documented in this report. The four-cylinder prototype data was encouraging for the micro-pilot ignition technology when compared to spark ignition. The objective for Phase II was to further develop and optimize the micropilot ignition system at the EECL for large bore, slow speed engines operating at low compression ratios. The primary elements of Micropilot Phase II were to evaluate the results for the 4-cylinder system prototype developed for Phase I, then optimize this system and prepare the technology for the field demonstration phase in Year 3. In all, there were twelve (12) tasks defined and executed to support objectives in a stepwise fashion. The optimized four-cylinder system data demonstrated significant progress compared to Phase I results, as well as traditional spark ignition systems. These laboratory results were enhanced, then verified via a field demonstration project during Phase III of the Micropilot Ignition program. An Implementation Team of qualified engine retrofit service providers was assembled to install the retrofit micropilot ignition system on an engine operated by El Paso Pipeline Group at a compressor station near Window Rock, Arizona. Testing of this demonstration unit showed that the same benefits identified by laboratory testing at CSU, i.e., reduced fuel consumption and exhaust emissions (NOx, THC, CO, and CH2O). Commercialization of the retrofit micropilot ignition technology is awaiting a ''market pull'', which is expected to materialize as the results of the field demonstration become known and accepted. The Implementation Team, comprised of Woodward Governor Company, Enginuity LLC, Hoerbiger Corporation of America, and DigiCon Inc., has direct experience with the technology development and implementation, and stands ready to promote and commercialize the retrofit micropilot ignition system.

Hydrogen vehicle fueling station  

DOE Green Energy (OSTI)

The authors describe a hydrogen vehicle fueling station that receives and stores hydrogen in liquid form and dispenses it either as a liquid or compressed gas. The economics that accrue from the favorable weight and volume advantages of liquid hydrogen support this concept both now and probably for some time to come. The model for liquid transfer to a 120-liter vehicle tank shows that transfer times under five minutes are feasible with pump-assisted transfer, or for pressure transfer with subcooling greater than 1 K. The model for compressed gas transfer shows that underfilling of nearly 30% can occur during rapid filling. Cooling the fill gas to 214 K completely eliminates underfilling.

INCREASED FLEXIBILITY OF TURBO-COMPRESSORS IN NATURAL GAS TRANSMISSION THROUGH DIRECT SURGE CONTROL  

Science Conference Proceedings (OSTI)

The objective of this Direct Surge Control project was to develop a new internal method to avoid surge of pipeline compressors. This method will safely expand the range and flexibility of compressor operations, while minimizing wasteful recycle flow at the lower end of the operating envelope. The approach is to sense the onset of surge with a probe that directly measures re-circulation at the impeller inlet. The signals from the probe are used by a controller to allow operation at low flow conditions without resorting to a predictive method requiring excessive margin to activate a recycle valve. The sensor developed and demonstrated during this project was a simple, rugged, and sensitive drag probe. Experiments conducted in a laboratory compressor clearly showed the effectiveness of the technique. Subsequent field demonstrations indicated that the increase in range without the need to recycle flow was on the order of 19% to 25%. The cost benefit of applying the direct surge control technology appears to be as much as $120 per hour per compressor for operation without the current level of recycle flow. This could amount to approximately $85 million per year for the U.S. Natural Gas Transmission industry, if direct surge control systems are applied to most pipeline centrifugal compressors.

Compressor and Hot Section Fouling in Gas Turbines- Causes and Effects  

E-Print Network (OSTI)

The fouling of axial flow compressors and turbines is a serious operating problem in gas turbine engines. These prime movers are being increasingly used in cogeneration applications and with the large air mass flow rate (e.g. 633 Lbs/Sec for a 80 MWe gas turbine) foulants even in the ppm range can cause deposits on the blading resulting in severe performance decrements. This is a common operating problem experienced by almost all operators of gas turbines. The effect of compressor fouling is a drop in airflow and a drop in compressor isentropic efficiency. Fouling of the axial compressor results in a drop in output and thermal efficiency of the system. In some cases, fouling can also result in surge problems as its effect is to move the compressor surge line to the right i.e. towards the operating line. This paper discusses the mechanism of fouling and the aerodynamic and thermodynamic effects. This paper also discusses types of foulants commonly experienced, detection methods and filtration techniques. A brief discussion of turbine fouling, which is particularly relevant when heavy fuels are utilized, is also discussed.

Economic and technical analysis of distributed utility benefits for hydrogen refueling stations. Final report  

SciTech Connect

This report presents the potential economic benefits of operating hydrogen refueling stations to accomplish two objectives: supply pressurized hydrogen for vehicles, and supply distributed utility generation, transmission and distribution peaking energy and capacity to the utility. The study determined under what circumstances using a hydrogen-fueled generator as a distributed utility generation source, co-located with the hydrogen refueling station components (electrolyzer and storage), would result in cost savings to the station owner, and hence lower hydrogen production costs. The systems studied include a refueling station (including such components as an electrolyzer, storage, hydrogen dispensers, and compressors) plus on-site hydrogen fueled electricity generation units (e.g., fuel cells or combustion engines). The operational strategy is to use off-peak electricity in the electrolyzer to fill hydrogen storage, and to dispatch the electricity generation about one hour per day to meet the utility`s local and system peaks. The utility was assumed to be willing to pay for such service up to its avoided generation, fuel, transmission and distribution costs.

Experimental analysis of pressure distribution in a twin screw compressor for multiphase duties  

SciTech Connect

This paper presents the results of an experimental investigation of pressure distribution inside working chamber of a twin screw compressor for multiphase duties. A mathematical model for describing the pressure distribution inside working chamber is proposed. By means of a small pressure transducer embedded into the groove at the root of the rotor, the pressure distributions of a multiphase compressor under various running conditions have been recorded successfully to verify the model. It is found that the pressure curve during the discharge process has a higher level under the conditions of the lower gas void fraction, higher discharge pressure, higher rotational speed and higher inlet pressure. The pressure distribution calculated by model in this paper shows good agreement with the data recorded by a small pressure sensor in a prototype multiphase compressor at the high gas void fractions under different operating conditions.

Nonlinear Control and Modeling of Rotating Stall in an Axial Flow Compressor  

E-Print Network (OSTI)

This thesis focuses on understanding the use of air injection as a means of controlling rotating stall in an axial flow compressor, involving modeling, dynamical systems analysis, and experimental investigations. The first step towards this understanding was the development of a low order model for air injection control, the starting point of which was the Moore and Greitzer model for axial flow compressors. The Moore and Greitzer model was extended to include the effects of air injection and bifurcation analysis was performed to determine how the closed loop system dynamics are different from those of the open loop system. This low order model was then used to determine the optimal placement of the air injection actuators. Experimental work focused on verifying that the low order model, developed for air injection actuation, qualitatively captured the behavior of the Caltech compressor rig. Open loop tests were performed to determine how the placement of the air injectors on the rig a...

Development of a Hybrid Compressor/Expander Module for Automotive Fuel Cell Applications  

DOE Green Energy (OSTI)

In this program TIAX LLC conducted the development of an advanced technology compressor/expander for supplying compressed air to Proton Exchange Membrane (PEM) fuel cells in transportation applications. The overall objective of this program was to develop a hybrid compressor/expander module, based on both scroll and high-speed turbomachinery technologies, which will combine the strengths of each technology to create a concept with superior performance at minimal size and cost. The resulting system was expected to have efficiency and pressure delivery capability comparable to that of a scroll-only machine, at significantly reduced system size and weight when compared to scroll-only designs. Based on the results of detailed designs and analyses of the critical system elements, the Hybrid Compressor/Expander Module concept was projected to deliver significant improvements in weight, volume and manufacturing cost relative to previous generation systems.

Variable gas spring for matching power output from FPSE to load of refrigerant compressor  

DOE Patents (OSTI)

The power output of a free piston Stirling engine is matched to a gas compressor which it drives and its stroke amplitude is made relatively constant as a function of power by connecting a gas spring to the drive linkage from the engine to the compressor. The gas spring is connected to the compressor through a passageway in which a valve is interposed. The valve is linked to the drive linkage so it is opened when the stroke amplitude exceeds a selected limit. This allows compressed gas to enter the spring, increase its spring constant, thus opposing stroke increase and reducing the phase lead of the displacer ahead of the piston to reduce power output and match it to a reduced load power demand. 6 figs.

Demonstration of Natural Gas Engine Driven Air Compressor Technology at Department of Defense Industrial Facilities  

E-Print Network (OSTI)

Recent downsizing and consolidation of Department of Defense (DOD) facilities provides an opportunity to upgrade remaining facilities with more efficient and less polluting equipment. Use of air compressors by the DOD is widespread and the variety of tools and machinery that operate on compressed air is increasing. The energy cost of operating a natural gas engine-driven air compressor (NGEDAC) is usually lower than the cost of operating an electric-driven air compressor. Initial capital costs are offset by differences in prevailing utility rates, efficiencies of partial load operation, reductions in peak demand, heat recovery, and avoiding the cost of back-up generators. Natural gas, a clean-burning fuel, is abundant and readily available. In an effort to reduce its over-all environmental impact and energy consumption, the U.S. Army plans to apply NGEDAC technology in support of fixed facilities compressed air systems. Site assessment and demonstration results are presented in this paper.

Running fermi with one-stage compressor: advantages, layout,performance  

Science Conference Proceedings (OSTI)

CBP-Tech Note-345 (July 2005), devoted to a study of microbunching instability in FERMI@ELETTRA linac quotes '...the above analysis shows that the most of the gain in microbunching instability occurs after BC2, i.e. after transformation of the energy modulation to the spatial modulation that takes place in BC2. It is possible to avoid that if we use only BC1 for all our needs for bunch compression. There are also additional advantages for a mitigation of the microbunching instability related to that. First, we would need to increase R56 in BC1 (for given energy chirp in the electron beam). Second, a relative energy spread is significantly larger at BC1 than at BC2. Both these factors would contribute to instability suppression due to increased Landau damping effect.' One additional argument was however missed in that report. Instability smearing due to finite emittance is stronger in BC1 simply because the geometrical emittance is larger than in BC2. In spite of the considerations in favor of a lattice with one-stage compressor, it was thought at the time that the two bunch compressors configuration was still preferable as it appeared difficult to obtain a flat-flat distribution at the end of the linac with only one bunch compressor. A flat-flat distribution has constant medium energy and a constant peak current along the electron bunch. Now, two years later and more studies behind, this problem is solvable. It has been demonstrated1 that shaping the intensity of the electron bunch at the injector using intensity modulation of the photocathode laser allows to use the linac structural wake fields to advantage to obtain a flat-flat distribution at the end of the linac in a two-stage compressor. This report shows that, using the back-tracking technique, it is possible to obtain a flat-flat distribution also in a single-stage compressor. Preliminary results of a study of the microbunching instability applied to the FERMI lattice with one-stage compressor are shown in this report . There is concern that the effect of jitter in accelerator parameters is more pronounced with one bunch compressor: the results of jitter studies are given and are compared with the case of a two-stage compressor.

Compressor fault identification from overall performance data based on adaptive stage stacking  

SciTech Connect

In the present paper a method for the identification of faulty stages in a multistage compressor is presented. The values of overall compressor parameters, namely mass flow rate, pressure ratio, and efficiency, at different operating points are the input data to the method. Employing these data, the method gives the location and the number of faulty stages, as well as the amount of deviation from intact condition performance. It is shown that the kind of fault that has caused stage performance deterioration can be identified. Features of the method, such as generality of applicability, input data requirement, and reliability of the findings, are discussed.

Topping cycles and advanced conversion machinery for central power stations  

SciTech Connect

From thermal power conference; Pullman, Washington, USA (3 Oct 1973). The possibility of developing dynamic conversion machines for topping cycles --- expanders and turbines ---that might utilize refractory materials not previously applied to this purpose is investigated. A technological basis for topping cycle systems that will extend the conversion efficiency of central power stations to the range of 55 to 60% is provided. The performance of a small (500 cm/sup 3/ displacement) graphite helical rotor compressor-expander set operating on inert gas for nearly 300 hr at temperatures up to 1500 deg C and rotor speeds to 14,000 rpm is described. In a related program, turbine blades and sound monolithic bodies up to 36 in. characteristic dimension were fabricated of the refractory compounds silicon nitride (Si/sub 3/N/sub 4/) and silicon carbide (SiC), which are compatible with air and combustion products. The application of available materials and power-conversion technology to permit a significant improvement in energy conversion efficiency is discussed. The demonstration of this capability is proposed by devising topping cycle systems incorporating ceramic engines capable of extracting useful energy from combustion heat sources at conditions presently inaccessible. 12 references.

On the effect of pulsating flow on surge margin of small centrifugal compressors for automotive engines  

Science Conference Proceedings (OSTI)

Surge is becoming a limiting factor in the design of boosting systems of downsized diesel engines. Although standard compressor flowcharts are used for the selection of those machines for a given application, on-engine conditions widely differ from steady flow conditions, thus affecting compressor behaviour and consequently surge phenomenon. In this paper the effect of pulsating flow is investigated by means of a steady gas-stand that has been modified to produce engine-like pulsating flow. The effect of pressure pulses' amplitude and frequency on the compressor surge line location has been checked. Results show that pulsating flow in the 40-67 Hz range (corresponding to characteristic pulsation when boosting an internal combustion engine) increases surge margin. This increased margin is similar for all the tested frequencies but depends on pulsation amplitude. In a further step, a non-steady compressor model is used for modelling the tests, thus allowing a deeper analysis of the involved phenomena. Model results widely agree with experimental results.

The design, selection, and application of oil-free screw compressors for fuel gas service  

SciTech Connect

Fuel gas compressors installed in cogeneration systems must be highly reliable and efficient machines. The screw compressor can usually be designed to meet most of the gas flow rates and pressure conditions generally required for such installations. To an ever-increasing degree, alternative sources are being found for the fuel gas supply, such as coke-oven gas, blast-furnace gas, flare gas, landfill gas, and synthesis gas from coal gasification or from pyrolysis. A feature of the oil-free screw compressor when such gases are being considered is the isolation of the gas compression space from the bearing and gear lubrication system by using positive shaft seals. This ensures that the process gas cannot be contaminated by the lubricating oil, and that there is not risk of loss of lubricant viscosity by gas solution in the oil. This feature enables the compressed gas to contain relatively high levels of particulate contamination without danger of ``sludge`` formation, and also permits the injection of water or liquid solvents into the compression space, to reduce the temperature rise due to the heat of compression, or to ``wash`` any particulate manner through the compressor.

INCREASED FLEXIBILITY OF TURBO-COMPRESSORS IN NATURAL GAS TRANSMISSION THROUGH DIRECT SURGE CONTROL  

Science Conference Proceedings (OSTI)

This preliminary phase 1 report summarizes the background and the work on the ''Increased Flexibility of Turbo-Compressors in Natural Gas Transmission through Direct Surge Control'' project to date. The importance of centrifugal compressors for natural gas transmission is discussed, and the causes of surge and the consequences of current surge control approaches are explained. Previous technology development, including findings from early GMRC research, previous surge detection work, and selected publications, are presented. The project is divided into three Phases to accomplish the project objectives of verifying near surge sensing, developing a prototype surge control system (sensor and controller), and testing/demonstrating the benefits of direct surge control. Specification for the direct surge control sensor and controller developed with guidance from the industry Oversight Committee is presented in detail. Results of CFD modeling conducted to aid in interpreting the laboratory test results are shown and explained. An analysis of the system dynamics identified the data sampling and handling requirements for direct surge control. A detailed design process for surge detection probes has been developed and explained in this report and has been used to prepare drag probes for the laboratory compressor test and the first field test. The surge detection probes prepared for testing have been bench tested and flow tested to determine and calibrate their sensitivity to flow forces as shown in data presented in this report. The surge detection drag probes have been shown to perform as expected and as required to detect approaching surge. Laboratory test results of surge detection in the SwRI centrifugal compressor demonstrated functionality of the surge detection probes and a change in the impeller inlet flow pattern prior to surge. Although the recirculation cannot be detected because of the specific geometry of this compressor, there are changes that indicate the approach of surge that can be detected. Preparations for a field test had been completed at one point in the project. However, a failure of the surge probe wiring just inside the compressor case has caused a delay in the field testing. Repairs for the wiring in the compressor have been scheduled and the field test will take place shortly after the repairs.

Assessment of HTGR Helium Compressor Analysis Tool Based on Newton-Raphson Numerical Application to Through-flow Analysis  

SciTech Connect

This study describes the development of a computer program for analyzing the off-design performance of axial flow helium compressors, which is one of the major concerns for the power conversion system of a high temperature gas-cooled reactor (HTGR). The compressor performance has been predicted by the aerodynamic analysis of meridional flow with allowances for losses. The governing equations have been derived from Euler turbomachine equation and the streamline curvature method, and then they have been merged into linearized equations based on the Newton-Raphson numerical method. The effect of viscosity is considered by empirical correlations to introduce entropy rises caused by primary loss sources. Use of the method has been illustrated by applying it to a 20-stage helium compressor of the GTHTR300 plant. As a result, the flow throughout the stages of the compressor has been predicted and the compressor characteristics have been also investigated according to the design specification. The program results show much better stability and good convergence with respect to other through-flow methods, and good agreement with the compressor performance map provided by JAEA. (authors)

Japanese and American competition in the development of scroll compressors and its impact on the American air conditioning industry  

SciTech Connect

This report examines the technological development of scroll compressors and its impact on the air conditioning equipment industry. Scroll compressors, although considered to be the compressors of the future for energy-efficient residential heat pumps and possibly for many other applications, are difficult to manufacture on a volume-production base. The manufacturing process requires computer-aided, numerically controlled tools for high-precision fabrication of major parts. Japan implemented a global strategy for dominating the technological world market in the 1970s, and scroll compressor technology benefited from the advent of new-generation machine tools. As a result, if American manufacturers of scroll compressors purchase or are essentially forced to purchase numerically controlled tools from Japan in the future, they will then become dependent on their own competitors because the same Japanese conglomerates that make numerically controlled tools also make scroll compressors. This study illustrates the importance of the basic machine tool industry to the health of the US economy. Without a strong machine tool industry, it is difficult for American manufacturers to put innovations, whether patented or not, into production. As we experience transformation in the air conditioning and refrigeration market, it will be critical to establish a consistent national policy to provide healthy competition among producers, to promote innovation within the industry, to enhance assimilation of new technology, and to eliminate practices that are incompatible with these goals. 72 refs., 8 figs., 1 tab.

Investigation of possible csr induced energy spread effects with the A0 photoinjector bunch compressor  

Science Conference Proceedings (OSTI)

The bunch compressor of the A0 Photoinjector at Fermilab was removed this past spring to install a transverse to longitudinal emittance exchange experiment. Prior to its removal questions arose about the possibility of observing the effects of Coherent Synchrotron Radiation on the compressed beam. The energy spread of the beam with and without compression was measured to observe any changes. Various beam charges were used to look for square law effects associated with CSR. No direct observation of CSR in the compressor was attempted because the design of the vacuum chamber did not allow it. In this paper we report the results of these experiments and comparison with simulations using ASTRA and CSRTrack. The results are also compared with analytical approximations.

X-Band Active-Passive Rf Pulse Compressor with Plasma Switches  

SciTech Connect

As proposed by SLAC, the efficiency of a pulse compressor of the SLED-II type could be increased by changing both the phase of the microwave source and the coupling coefficient of the delay line. In the existing SLED-II system at frequency 11.4 GHz, the resonant delay line is coupled with the source via an iris with a constant reflection coefficient. Replacement of the iris with an active component makes it possible to create an active SLED-II system. In this paper, the use of plasma switches as the active elements is discussed. Plasma switches have been developed and tested at a high-power level for production of flattop compressed pulses. Active switching of SLED-II has demonstrated a marked increase in efficiency (by 20%) and power gain (by 37%) as compared with passive switching. The active compressor has produced 173 ns rf flattop output pulses with a power of about 112 MW.

Thermodynamic modeling and optimization of a screw compressor chiller and cooling tower system  

E-Print Network (OSTI)

This thesis presents a thermodynamic model for a screw chiller and cooling tower system for the purpose of developing an optimized control algorithm for the chiller plant. The thermodynamic chiller model is drawn from the thermodynamic models developed by Gordon and Ng (1996). However, the entropy production in the compressor is empirically related to the pressure difference measured across the compressor. The thermodynamic cooling tower model is the Baker & Shryock cooling tower model that is presented in ASHRAE Handbook - HVAC Systems and Equipment (1992). The models are coupled to form a chiller plant model which can be used to determine the optimal performance. Two correlations are then required to optimize the system: a wet-bulb/setpoint correlation and a fan speed/pump speed correlation. Using these correlations, a "quasi-optimal" operation can be achieved which will save 17% of the energy consumed by the chiller plant.

A relation between the degree of pulse compression and energy efficiency is derived for femtosecond laser pulse compressors that utilise spectral broadening of pulses in a gas-filled capillary. We show that the degree of compression has a maximum at an energy efficiency from 15% to 30%. A 15-fold compression of a 290-fs pulse with an energy efficiency of 24% is demonstrated.

Compressor Calorimeter Test of R-410A Alternatives R-32, DR-5, and L-41a  

SciTech Connect

As a contribution to the AHRI Low-GWP Alternative Refrigerants Evaluation Program (AREP), this study compares performance of alternative refrigerants R32, DR-5, and L-41A to that of refrigerant R-410A (baseline) in a scroll compressor designed for air-conditioning and heat pump applications. Compressor calorimeter tests were performed to evaluate the performance of the lower-GWP alternative refrigerants in place of the common refrigerant R-410A in a 36,000 Btu/hr compressor calorimeter using a compressor having a nominal rated capacity of 21,300 Btu/hr. Tests were conducted over a suction dew point temperature range of 10 F to 55 F in 5 F increments and a discharge dew point temperature range of 70 F to 140 F in 10 F increments. All the tests were performed with 20 F superheat, 40 F superheat and 65 F suction temperature. A liquid subcooling level of 15 F was maintained for all the test conditions. The tests showed that performance of these three lower-GWP alternative refrigerants is comparable to that of R-410A. For the 20 F superheat and 15 F subcooling test conditions, EERs of R32, DR-5, and L-41A were 90% to 99%, 96% to 99%, and 94% to 101%, respectively, compared to that of R-410A. Similarly, cooling capacities of R32, DR-5, and L-41A were 98% to 103%, 92% to 96%, and 84% to 92%, respectively, compared to that of R-410A.

Active Control of an Axial Flow Compressor via Pulsed Air Injection  

E-Print Network (OSTI)

This paper presents the use of pulsed air injection to control the onset of rotating stall in a low-speed, axial flow compressor. By measuring the unsteady pressures near the rotor face, a control algorithm determines the magnitude and phase of the first mode of rotating stall and controls the injection of air in the front of the rotor face. Experimental results show that this technique slightly extends the stall point of the compressor and eliminates the hysteresis loop normally associated with rotating stall. A parametric study is used to determine the optimal control parameters for suppression of stall. Analytic results---using a low-dimensional model developed by Moore and Greitzer combined with an unsteady shift in the compressor characteristic to model the injectors---give further insights into the operation of the controller. Based on this model, we show that the behavior of the experiment can be explained as a change in the bifurcation behavior of the system under non...

Low-friction coatings for air bearings in fuel cell air compressors  

DOE Green Energy (OSTI)

In an effort to reduce fuel consumption and emissions, hybrid vehicles incorporating fuel cell systems are being developed by automotive manufacturers, their suppliers, federal agencies (specifically, the US Department of Energy) and national laboratories. The fuel cell system will require an air management subsystem that includes a compressor/expander. Certain components in the compressor will require innovative lubrication technology in order to reduce parasitic energy losses and improve their reliability and durability. One such component is the air bearing for air turbocompressors designed and fabricated by Meruit, Inc. Argonne National Laboratory recently developed a carbon-based coating with low friction and wear attributes; this near-frictionless-carbon (NFC) coating is a potential candidate for use in turbocompressor air bearings. The authors present here an evaluation of the Argonne coating for air compressor thrust bearings. With two parallel 440C stainless steel discs in unidirectional sliding contact, the NFC reduced the frictional force four times and the wear rate by more than two orders of magnitude. Wear mechanism on the uncoated surface involved oxidation and production of iron oxide debris. Wear occurred on the coated surfaces primarily by a polishing mechanism.

Timber Mountain Precipitation Monitoring Station  

SciTech Connect

A precipitation monitoring station was placed on the west flank of Timber Mountain during the year 2010. It is located in an isolated highland area near the western border of the Nevada National Security Site (NNSS), south of Pahute Mesa. The cost of the equipment, permitting, and installation was provided by the Environmental Monitoring Systems Initiative (EMSI) project. Data collection, analysis, and maintenance of the station during fiscal year 2011 was funded by the U.S. Department of Energy, National Nuclear Security Administration, Nevada Site Office Environmental Restoration, Soils Activity. The station is located near the western headwaters of Forty Mile Wash on the Nevada Test and Training Range (NTTR). Overland flows from precipitation events that occur in the Timber Mountain high elevation area cross several of the contaminated Soils project CAU (Corrective Action Unit) sites located in the Forty Mile Wash watershed. Rain-on-snow events in the early winter and spring around Timber Mountain have contributed to several significant flow events in Forty Mile Wash. The data from the new precipitation gauge at Timber Mountain will provide important information for determining runoff response to precipitation events in this area of the NNSS. Timber Mountain is also a groundwater recharge area, and estimation of recharge from precipitation was important for the EMSI project in determining groundwater flowpaths and designing effective groundwater monitoring for Yucca Mountain. Recharge estimation additionally provides benefit to the Underground Test Area Sub-project analysis of groundwater flow direction and velocity from nuclear test areas on Pahute Mesa. Additionally, this site provides data that has been used during wild fire events and provided a singular monitoring location of the extreme precipitation events during December 2010 (see data section for more details). This letter report provides a summary of the site location, equipment, and data collected in fiscal year 2011.

An NLC-Style Short Bunch Length Compressor in the SLAC Linac*  

E-Print Network (OSTI)

Experimental tests of a second bunch length compressor in a linac is important for the next generation of linear colliders and for other future accelerators. These future accelerators need bunches with lengths of order 0.06- 0.2 mni. At these lengths, new accelerator dynamics will be encountered. We have studied the possibility of constructing a second compressor with the present SLAC linac and have found a reasonable design. The core of this project is to recontigure an old beamline (BL-90) at the 1OOOm location in the linac to: (1) extract a 10 GeV bunch, (2) pass it through a new 96 m long transport line in which length compression is done, and (3) reinject the beam into the main linac in an available drift section. Using the resulting compressed bunch, accelerator physics tests would be performed in the remaining downstream linac with the resulting very high charge density. The bunch compression in this transport line results Erom ExWiq BASlWBL90 aipor the TRANSPORT element R56 as determined from the optics of the transport line. AZ = R56 AEJE.

Compression zone of a magnetoplasma compressor as a source of extreme UV radiation  

Science Conference Proceedings (OSTI)

Results from experimental studies of extreme UV (EUV) radiation from the compression zone of a magnetoplasma compressor (MPC) operating with xenon are presented. Two MPC operating modes that differ in the method of xenon injection into the discharge were studied. It is shown that EUV radiation in the wavelength range of 5-80 nm is emitted from the compression zone. In the MPC operating mode with local xenon injection directly into the compression zone surrounded by helium plasma, the radiation power reaches it peak value of 16-18 kW in the wavelength range of 12.2-15.8 nm.

The application of laser anemometry techniques in turbomachinery facilities is a challenging dilemma requiring an anemometer system with special qualities. Here, we describe the use of a novel laser anemometry technique applied to a small 4.5 kg/s, 4:1 pressure ratio centrifugal compressor. Sample velocity profiles across the blade pitch are presented for a single location along the rotor. The results of the intra-blade passage velocity measurements will ultimately be used to verify CFD 3-D viscous code predictions.

Practical use of three-dimensional inverse method for compressor blade design  

SciTech Connect

The practical utility of a three-dimensional inverse viscous method is demonstrated by carrying out a design modification of a first-stage rotor in an industrial compressor. In this design modification study, the goal is to improve the efficiency of the original blade while retaining its overall aerodynamic, structural, and manufacturing characteristics. By employing a simple modification to the blade pressure loading distribution (which is the prescribed flow quantity in this inverse method), the modified blade geometry is predicted to perform better than the original design over a wide range of operating points, including an improvement in choke margin.

A new type of bunch compressor and seeding of a short-wavelength coherent radiation.  

Science Conference Proceedings (OSTI)

Transverse-to-longitudinal emittance exchange was proposed in [1] as a tool for an effective matching of the electron beam phase space to requirements of a possible application. Here we propose a new purpose, namely, use of two consecutive emittance exchanges equipped with the telescope between them for a bunch compression that can be done without the energy chirp in the electron bunch. In principle it allows to reduce the electron peak current in the linac by moving the bunch compressor to the end of the linac and, thus, to relax collective effects associated with high peak currents. It is also possible to have a split-action compression when the first part is done inside the low-energy part of the linac and the second and final part is done after the linac. We also demonstrate how proposed bunch compressor can be used for frequency up-conversion of the energy modulation provided by the laser interacting with the electron beam and thus can prepare a significantly higher frequency seed for seeded free-electron lasers. The same approach can be used for a frequency down-conversion that can be useful for generation of THz radiation.

FINAL DESIGN OF ILC RTML EXTRACTION LINE FOR SINGLE STAGE BUNCH COMPRESSOR  

SciTech Connect

The use of single stage bunch compressor (BC) in the International Linear Collider (ILC) Damping Ring to the Main Linac beamline (RTML) requires new design for the extraction line (EL). The EL located downstream of the BC will be used for both an emergency abort dumping of the beam and the tune-up continuous train-by-train extraction. It must accept both compressed and uncompressed beam with energy spread of 3.54% and 0.15% respectively. In this paper we report the final design that allowed minimizing the length of such extraction line while offsetting the beam dumps from the main line by 5m distance required for acceptable radiation level in the service tunnel. Proposed extraction line can accommodate beams with different energy spreads at the same time providing the beam size suitable for the aluminum ball dump window. We described the final design of the ILC RTML extraction line located downstream of the new single-stage bunch compressor. The extraction line is only 24m long and is capable of accepting and transmitting 220kW of beam power. The EL can be used for both fast intra-train and continual extraction, and is capable of accepting both 0.15% and 3.54% energy spread beams at 5MeV and 4.37MeV respectively.

Dynamically balanced, hydraulically driven compressor/pump apparatus for resonant free piston Stirling engines  

DOE Patents (OSTI)

A compressor, pump, or alternator apparatus is designed for use with a resonant free piston Stirling engine so as to isolate apparatus fluid from the periodically pressurized working fluid of the Stirling engine. The apparatus housing has a first side closed by a power coupling flexible diaphragm (the engine working member) and a second side closed by a flexible diaphragm gas spring. A reciprocally movable piston is disposed in a transverse cylinder in the housing and moves substantially at right angles relative to the flexible diaphragms. An incompressible fluid fills the housing which is divided into two separate chambers by suitable ports. One chamber provides fluid coupling between the power diaphragm of the RFPSE and the piston and the second chamber provides fluid coupling between the gas spring diaphragm and the opposite side of the piston. The working members of a gas compressor, pump, or alternator are driven by the piston. Sealing and wearing parts of the apparatus are mounted at the external ends of the transverse cylinder in a double acting arrangement for accessibility. An annular counterweight is mounted externally of the reciprocally movable piston and is driven by incompressible fluid coupling in a direction opposite to the piston so as to damp out transverse vibrations.

High speed imager test station  

DOE Patents (OSTI)

A test station enables the performance of a solid state imager (herein called a focal plane array or FPA) to be determined at high image frame rates. A programmable waveform generator is adapted to generate clock pulses at determinable rates for clock light-induced charges from a FPA. The FPA is mounted on an imager header board for placing the imager in operable proximity to level shifters for receiving the clock pulses and outputting pulses effective to clock charge from the pixels forming the FPA. Each of the clock level shifters is driven by leading and trailing edge portions of the clock pulses to reduce power dissipation in the FPA. Analog circuits receive output charge pulses clocked from the FPA pixels. The analog circuits condition the charge pulses to cancel noise in the pulses and to determine and hold a peak value of the charge for digitizing. A high speed digitizer receives the peak signal value and outputs a digital representation of each one of the charge pulses. A video system then displays an image associated with the digital representation of the output charge pulses clocked from the FPA. In one embodiment, the FPA image is formatted to a standard video format for display on conventional video equipment. 12 figs.

Investigation of a Sodium Vapor Compressor Jet for Nuclear Propulsion of Aircraft  

SciTech Connect

?Analysis indicates that, in order to achieve supersonic flight with nuclear powered aircraft, a reactor -power plant combination capable of operating at temperatures considerably in excess of current practice must be developed. It is pointed out that there exist two general avenues of approach toward the goal of attaining high temperature reactors and power plants. The first approach involves the continuation and augmentation of research along the lines pursued by the conventional turbo-jet engine manufacturer, namely a search for material coatings or materials that will retain structural strength in high temperature oxidizing atmospheres. The second approach seeks to take advantage of the peculiar characteristics of the compressor-jet engine that permit the operation of the high temperature components in a non-oxidizing atmosphere. The results of a preliminary design study of a supersonic aircraft powered by a high temperature sodium, liquid vapor compressor -jet engine are summarized. The analysis considered, in as much detail as was warranted by the limited experimental information available, the characteristics of the reactor, power plant and airframe involved in determining performance. This study has been conducted for the purpose of guiding future, long -t e r rn , research work along the lines of high temperature reactors and power plants for aircraft propulsion. The sodium vapor compressor -jet is not presented as an engine that is presently considered feasible nor is any attempt made to establish a time table for its development. ?The present status of reactor -power plant combinations of the type discussed in this report is such that the configurations presented and the thermodynamic requirements set forth are highly c onj ectural. However, in light of the promising results thus far obtained from very limited experimentation in the field of high temperature materials not subject to oxidizing atmospheres, it appears worthwhile to continue a research effort along these lines in the expectation of making high temperature, high performance aircraft a reality. This report is based upon studies conducted for the Atomic Energy Commission under Contract AT-40-l-GEN-1064. These studies were concluded on September 1, 1951, and were informally made available to the Aircraft Nuclear Propulsion Group at ORNL at that time.

Modeled and measured effects of compressor downsizing in an existing air conditioner/heat pump in the cooling mode  

SciTech Connect

It is not uncommon to find oversized central air conditioners in residences. HVAC contractors sometimes oversize central air conditioners for one reason or another--some to the point that they may be 100% larger than needed to meet the load. Retrofit measures done to improve house envelope and distribution system efficiency also contribute to HVAC oversizing, as they reduce house heating and cooling loads. Proper sizing of an air conditioner or heat pump allows more efficient operation and provides a more comfortable environment than a highly oversized unit. Another factor that lowers operating efficiency is an improper refrigerant charge. Field inspections have revealed that about half of the units checked were not properly charged. An option available to homeowners with oversized air conditioners is to replace the existing compressor with a smaller, more efficient compressor, rather than purchasing a new, smaller unit. Such a retrofit may be economically justified, especially during a compressor failure, provided the oversizing of the existing unit is not too great. A used, 15-year old, single-package heat pump with a capillary tube expansion device on the indoor coil was purchased and tested in a set of environmental chambers to determine its cooling performance at various conditions. The system was also modeled to estimate its existing performance, and that with two different types of retrofitted state-of-the-art (SOA) efficient compressors with about 30% less capacity than the original compressor. This reduced the overall system cooling capacity by about 25%. Modeling estimated that the retrofit would increase system EER at 95 F by 30%, SEER by 34%, and reduce power demand by 39% compared to the existing unit. Reduced cycling losses account for the higher increase in SEER.

Analyzing auxiliary system in nuclear generating stations  

Science Conference Proceedings (OSTI)

The design for most nuclear generating stations took place before the widespread use of computerized engineering tools. The manual design basis calculations that were performed vary in quantity from only a few feet of shelf space for some of the first stations to bookcases full for stations that are now receiving their operating licenses. Some of the following issues may apply to the manual calculation files of any nuclear station: Errors and lack of detail in hand calculations; Calculations that may not document the required safety functions; Calculations that lag behind the as-built condition of the station; Documentation that does not add up to a coherent whole; and incomplete auditability and traceability of data. The increasing use of computerized tools in nuclear generating station analysis has helped address the hand-calculation problems. The use of a master system model to study various scenarios also ensures that uniform assumptions are being used for all related analyses. This article presents an overview of how computerized tools are being used for both ac and dc auxiliary system calculations. Problems that may be created by the use of these tools are discussed, along with a review of those issues specific to nuclear generating stations.

Cryogenic Viscous Compressor Development and Modeling for the ITER Vacuum System  

SciTech Connect

The ITER vacuum system requires a roughing pump system that can pump the exhaust gas from the torus cryopumps to the tritium exhaust processing plant. The gas will have a high tritium content and therefore conventional vacuum pumps are not suitable. A pump called a cryogenic viscous compressor (CVC) is being designed for the roughing system to pump from ~500 Pa to 10 Pa at flow rates of 200 Pa-m3/ s. A unique feature of this pump is that is allows any helium in the gas to flow through the pump where it is sent to the detritiation system before exhausting to atmosphere. A small scale prototype of the CVC is being tested for heat transfer characteristics and compared to modeling results to ensure reliable operation of the full scale CVC.

High-Power Plasma Switch for 11.4 GHz Microwave Pulse Compressor  

SciTech Connect

Results obtained in several experiments on active RF pulse compression at X-band using a magnicon as the high-power RF source are presented. In these experiments, microwave energy was stored in high-Q TE01 and TE02 modes of two parallel-fed resonators, and then discharged using switches activated with rapidly fired plasma discharge tubes. Designs and high-power tests of several versions of the compressor are described. In these experiments, coherent pulse superposition was demonstrated at a 59 MW level of incident power. The compressed pulses observed had powers of 5070 MW and durations of 4070 ns. Peak power gains were measured to be in the range of 7:111:1 with efficiency in the range of 5063%.

CFD modeling of a gas turbine combustor from compressor exit to turbine inlet  

SciTech Connect

Gas turbine combustor CFD modeling has become an important combustor design tool in the past few years, but CFD models are generally limited to the flow field inside the combustor liner at the diffuser/combustor annulus region. Although strongly coupled in reality, the two regions have rarely been coupled in CFD modeling. A CFD calculation for a full model combustor from compressor diffuser exit to turbine inlet is described. The coupled model accomplishes the following two main objectives: (1) implicit description of flow splits and flow conditions for openings into the combustor liner, and (2) prediction of liner wall temperatures. Conjugate heat transfer with nonluminous gas radiation (appropriate for lean, low emission combustors) is utilized to predict wall temperatures compared to the conventional approach of predicting only near wall gas temperatures. Remaining difficult issues such as generating the grid, modeling swirler vane passages, and modeling effusion cooling are also discussed.

Development of turbine driven centrifugal compressors for non-condensible gas removal at geothermal power plants. Final report  

SciTech Connect

Initial field tests have been completed for a Non-Condensible Gas (NCG) turbocompressor for geothermal power plants. It provides alternate technology to steam-jet ejectors and liquid-ring vacuum pumps that are currently used for NCG removal. It incorporates a number of innovative design features to enhance reliability, reduce steam consumption and reduce O&M costs. During initial field tests, the turbocompressor has been on-line for more than 4500 hours as a third stage compressor at The Geysers Unit 11 Power Plant. Test data indicates its overall efficiency is about 25% higher than a liquid-ring vacuum pump, and 250% higher than a steam-jet ejector when operating with compressor inlet pressures of 12.2 in-Hga and flow rates over 20,000 lbm/hr.

Hydrogen fuel dispensing station for transportation vehicles  

DOE Green Energy (OSTI)

A technical and economic assessment is being conducted of a hydrogen fuel dispensing station to develop an understanding of the infrastructure requirements for supplying hydrogen fuel for mobile applications. The study includes a process design of a conceptual small-scale, stand-alone, grassroots fuel dispensing facility (similar to the present-day gasoline stations) producing hydrogen by steam reforming of natural gas. Other hydrogen production processes (such as partial oxidation of hydrocarbons and water electrolysis) were reviewed to determine their suitability for manufacturing the hydrogen. The study includes an assessment of the environmental and other regulatory permitting requirements likely to be imposed on a hydrogen fuel dispensing station for transportation vehicles. The assessment concludes that a dispensing station designed to produce 0.75 million standard cubic feet of fuel grade (99.99%+ purity) hydrogen will meet the fuel needs of 300 light-duty vehicles per day. Preliminary economics place the total capital investment (in 1994 US dollars) for the dispensing station at $4.5 million and the annual operating costs at around $1 million. A discounted cash-flow analysis indicates that the fuel hydrogen product price (excluding taxes) to range between $1.37 to $2.31 per pound of hydrogen, depending upon the natural gas price, the plant financing scenario, and the rate of return on equity capital. A report on the assessment is due in June 1995. This paper presents a summary of the current status of the assessment.

Hydrogen fueling station development and demonstration  

DOE Green Energy (OSTI)

This is the final report of a one-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). This project sought to develop and demonstrate a hydrogen fueling station for vehicles. Such stations are an essential infrastructural element in the practical application of hydrogen as vehicle fuel, and a number of issues such as safety, efficiency, design, and operating procedures can only be accurately addressed by a practical demonstration. Regardless of whether the vehicle is powered by an internal combustion engine or fuel cell, or whether the vehicle has a liquid or gaseous fuel tank, the fueling station is a critical technology that is the link between the local storage facility and the vehicle.

Electrical Power Savings in Pump and Compressor Networks via Load Management  

E-Print Network (OSTI)

Large industrial plants commonly use multiple parallel units in pump and compressor networks for improved reliability. Sometimes, installed equipment capacity can far exceed actual requirements. This excess capacity can be translated into energy cost savings through optimum load management. A key decision parameter in determining the operating policy is the Trigger Point at which to switch from N units to N+1, and vice versa. The Trigger Point is defined as the actual flow rate at which the switching is made to the ideal (generally maximum) flow rate at which the switching should be made. At the plant under study, the implicit Trigger Point was generally found to be around 85%, probably because this made it easy to have a smooth transition during the switching operation. A number of pumping and compression networks were analyzed to determine what the potential savings would be if this trigger point were increased to 90 or 95%. The savings potential was found to range from 0 to 23%, with an average of 4.4%. Our study demonstrated that by tightening up operating policies to make sure that the minimum number of machines is being run, significant cost savings are possible with zero capital investment, and negligible sacrifice in operating flexibility or reliability. This paper describes the methodology used, as well as representative results from our study.

Design of Accumulator and Compressor Rings for the Project-X Based Proton Driver  

SciTech Connect

A Muon Collider (MC) and a Neutrino Factory (NF) - which may be considered as a step towards a MC - both require a high-power ({approx}4 MW) proton driver providing short (<1 m r.m.s. length) bunches for muon production. However, the driver repetition rates required for these two machines are different: {approx}15 Hz for MC and {approx}60 Hz for NF. This difference suggests employing two separate rings: one for accumulation of the proton beam from the Project-X linac in a few (e.g. 4) long bunches, the other for bunch compression - one by one for NF or all at a time for MC with simultaneous delivery to the target. The lattice requirements for these two rings are different: the momentum compaction factor in the accumulator ring should be large (and possibly negative) to avoid the microwave instability, while the compressor ring can be nearly isochronous in order to limit the required RF voltage and reduce the dispersion contribution to the beam size. In the present report we consider ring lattice designs which achieve these goals.

Multi-bottle, no compressor, mean pressure control system for a Stirling engine  

SciTech Connect

The invention relates to an apparatus for mean pressure control of a Stirling engine without the need for a compressor. The invention includes a multi-tank system in which there is at least one high pressure level tank and one low pressure level tank wherein gas flows through a maximum pressure and supply line from the engine to the high pressure tank when a first valve is opened until the maximum pressure of the engine drops below that of the high pressure tank opening an inlet regulator to permit gas flow from the engine to the low pressure tank. When gas flows toward the engine it flows through the minimum pressure supply line 2 when a second valve is opened from the low pressure tank until the tank reaches the engine's minimum pressure level at which time the outlet regulator opens permitting gas to be supplied from the high pressure tank to the engine. Check valves between the two tanks prevent any backflow of gas from occurring.

MHD compressor---expander conversion system integrated with GCR inside a deployable reflector  

DOE Green Energy (OSTI)

This work originates from the proposal MHD Compressor-Expander Conversion System Integrated with a GCR Inside a Deployable Reflector''. The proposal concerned an innovative concept of nuclear, closed-cycle MHD converter for power generation on space-based systems in the multi-megawatt range. The basic element of this converter is the Power Conversion Unit (PCU) consisting of a gas core reactor directly coupled to an MHD expansion channel. Integrated with the PCU, a deployable reflector provides reactivity control. The working fluid could be either uranium hexafluoride or a mixture of uranium hexafluoride and helium, added to enhance the heat transfer properties. The original Statement of Work, which concerned the whole conversion system, was subsequently redirected and focused on the basic mechanisms of neutronics, reactivity control, ionization and electrical conductivity in the PCU. Furthermore, the study was required to be inherently generic such that the study was required to be inherently generic such that the analysis an results can be applied to various nuclear reactor and/or MHD channel designs''.

Aerodynamically induced radial forces in a centrifugal gas compressor: Part 2 -- Computational investigation  

SciTech Connect

Radial loads and direction of a centrifugal gas compressor containing a high specific speed mixed flow impeller and a single tongue volute were determined both experimentally and computationally at both design and off-design conditions. The experimental methodology was developed in conjunction with a traditional ASME PTC-10 closed-loop test to determine radial load and direction. The experimental study is detailed in Part 1 of this paper (Moore and Flathers, 1998). The computational method employs a commercially available, fully three-dimensional viscous code to analyze the impeller and the volute interaction. An uncoupled scheme was initially used where the impeller and volute were analyzed as separate models using a common vaneless diffuser geometry. The two calculations were then repeated until the boundary conditions at a chosen location in the common vaneless diffuser were nearly the same. Subsequently, a coupled scheme was used where the entire stage geometry was analyzed in one calculation, thus eliminating the need for manual iteration of the two independent calculations. In addition to radial load and direction information, this computational procedure also provided aerodynamic stage performance. The effect of impeller front face and rear face cavities was also quantified. The paper will discuss computational procedures, including grid generation and boundary conditions, as well as comparisons of the various computational schemes to experiment. The results of this study will show the limitations and benefits of Computational Fluid Dynamics (CFD) for determination of radial load, direction, and aerodynamic stage performance.

Three-dimensional hybrid grid generator and unstructured flow solver for compressors and turbines  

E-Print Network (OSTI)

A numerical method for the simulation of compressible turbulent ?ows is presented. This method includes a novel hybrid grid generation for airfoil cascades and an unstructured mesh ?ow solver. The mesh tool incorporates a mapping technique and a grid smoothing method. The mapping technique is used to build an initial volume mesh and the grid smoothing method is used to improve the quality of the initial mesh. The grid smoothing is based on the optimization of mesh-quality parameters. The further improvement of the smoothed mesh is achieved by an edge-swapping and node-insertion technique. The unstructured ?ow solver is developed for a hybrid grid. This ?ow solver uses a rotational frame of reference. The convective and viscous ?uxes are numerically solved by an upwind scheme and an averaged nodal gradient. A higher-order spatial accuracy is achieved by a piece-wise linear reconstruction. An explicit multi-stage method is employed for integration in time. The Menter?s k ?? model is implemented to simulate the turbulence e?ects. The ?ow solver is validated against the analytical and experimental results. A parametric study is performed for a high speed centrifugal compressor.

FERROELECTRIC SWITCH FOR A HIGH-POWER Ka-BAND ACTIVE PULSE COMPRESSOR  

Science Conference Proceedings (OSTI)

Results are presented for design of a high-power microwave switch for operation at 34.3 GHz, intended for use in an active RF pulse compressor. The active element in the switch is a ring of ferroelectric material, whose dielectric constant can be rapidly changed by application of a high-voltage pulse. As envisioned, two of these switches would be built into a pair of delay lines, as in SLED-II at SLAC, so as to allow 30-MW ?s-length Ka-band pulses to be compressed in time by a factor-of-9 and multiplied in amplitude to generate 200 MW peak power pulses. Such high-power pulses could be used for testing and evaluation of high-gradient mm-wave accelerator structures, for example. Evaluation of the switch design was carried out with an X-band (11.43 GHz) prototype, built to incorporate all the features required for the Ka-band version.

SciTech Connect

This project assisted a private real estate developer in technically assessing the feasibility of integrating a central DHC system into a proposed 72 acre area mixed-use Planned Development (Central Station) just south of the Chicago Central Business District (Loop). The technical assessment concluded that a district heating and cooling system for Central Station will be feasible, provided that a major anchor load can be connected to the system. The system conceived for the site employs a modular approach that adjusts production capacity to actual load growth. The design concept includes gas-fired boilers for heating, gas turbine driven chillers for base loading, electric motor driven chillers for peaking, steam turbines for peak power and back pressure operation, and chilled water storage. Energy will be supplied to the users in the form of steam or low temperature hot water for heating, and low temperature chilled water for cooling.

Comparison of 1D and 2D CSR Models with Application to the FERMI@ELETTRA Bunch Compressors  

SciTech Connect

We compare our 2D mean field (Vlasov-Maxwell) treatment of coherent synchrotron radiation (CSR) effects with 1D approximations of the CSR force which are commonly implemented in CSR codes. In our model we track particles in 4D phase space and calculate 2D forces [1]. The major cost in our calculation is the computation of the 2D force. To speed up the computation and improve 1D models we also investigate approximations to our exact 2D force. As an application, we present numerical results for the Fermi{at}Elettra first bunch compressor with the configuration described in [1].

Environmental impact of HTGR power stations  

SciTech Connect

From ANS topical meeting on gas-cooled reactors: HTGR and GCFBR; Gatlinburg, Tennessee, USA (8 May 1974). The high-temperature gas-cooled reactor power station has all of the potential environmental impacts associated with any large nuclear station. Construction impacts can be minimized by proper planning and are usually of limited duration. The potentially most significant impacts of station operation result from the operation of the heat dissipation system. The use of cooling towers is assumed. The effects of salt deposition, fogging, and icing are expected to be minor. The magnitude of the adverse effects caused by intake and discharge such as entrainment of eggs, larvae, and fish and chemical impacts from blowdown can only be assessed for a specific site but may be signlficant. The impact of radionuclide releases, constrained by the as-low-as- is-practicable criteria, is small. The only potential environmental advantage over other reactor types is lower consumptive water use for the same net electric power production. (auth)

Windback seal design for gas compressors: a numerical and experimental study  

E-Print Network (OSTI)

Seals are considered one of the important flow elements of a turbomachinery device. Traditional labyrinth seals have proven their performance functionality by reducing leakage rates. Significant improvements on labyrinth seal functionality were obtained through altering the design geometry of labyrinth seals to prevent contamination across a seal and maintaining small leakage flowrates. This results in a windback seal that has only one tooth which continuously winds around the shaft like a screw thread. These seals are used in gas compressors to isolate the gas face seal from bearing oil. A purge gas is passed through the seal into the bearing housing. The helical design allows the seal to clear itself of any oil contamination. Windback seal performance is controlled through changing the seal geometry. A 2D graphical design tool for calculating the total and cavity leakage flowrates for windback seals is introduced. The effectiveness of the Fluent CFD (Computational Fluid Dynamics) commercial code to accurately predict the leakage rate for windback seals was evaluated. The objective is to determine if CFD simulations can be used along with a few experimental tests to study windback seals of this design with air as the working fluid. Comparison of measurement and predictions for a windback seal using the ?º-?µ turbulence model with enhanced wall treatment functions show predictions and measurements comparing very well with a maximum difference of 5% for leakage rate. Similarly, the leakage rate of the tested smooth seal compares favorably with two dimensional CFD predictions, with a difference of 2%-11% and 8%-15% using laminar and ?º-?µ turbulent flow models, respectively. The variation of leakage with shaft speed and pressure ratio across the seals is accurately predicted by the CFD simulations. Increasing the rotor speed to 15000 rpm increases the measured leakage flowrate for the windback seal by 2% at high differential pressure and 4.5% at low differential pressure, and decreases it by 10 % for the smooth seal. The effects of seal clearance, tooth pitch, cavity depth and the tooth number of starts on leakage flowrate, velocity and pressure distributions were studied numerically for three differential pressures and four rotor speeds.

Characterizing the Effects of Air Injection on Compressor Performance for Use in Active Control of Rotating Stall  

E-Print Network (OSTI)

Previous work has developed an air injection controller for rotating stall based on the idea of a shifting compressor characteristic and the Moore--Greitzer three state compressor model. In order to demonstrate this form of control experimentally, a series of open loop tests were performed to measure the performance characteristics of a low speed axial flow compression system when air is injected upstream of the rotor face. The position of the air injection port relative to the hub and the rotor face and the angle relative to the mean axial flow were varied. The tests show that the injection of air has drastic effects on the stalling mass flow rate and on the size of the hysteresis loop associated with rotating stall. The stalling mass flow rate was decreased by 10% and the hysteresis loop was completely eliminated under some conditions. The results of the open loop parametric study were then used to implement a closed loop control strategy based on a shifting characteristic. 1 Introdu...

Southeast regional experiment station. Final report  

DOE Green Energy (OSTI)

This is the final report of the Southeast Regional Experiment Station project. The Florida Solar Energy Center (FSEC), a research institute of the University of Central Florida (UCF), has operated the Southeast Regional Experiment Station (SE RES) for the US Department of Energy (DOE) since September 1982. Sandia National Laboratories, Albuquerque (SNLA) provides technical program direction for both the SE RES and the Southwest Regional Experiment Station (SW RES) located at the Southwest Technology Development Institute at Las Cruces, New Mexico. This cooperative effort serves a critical role in the national photovoltaic program by conducting system evaluations, design assistance and technology transfer to enhance the cost-effective utilization and development of photovoltaic technology. Initially, the research focus of the SE RES program centered on utility-connected PV systems and associated issues. In 1987, the SE RES began evaluating amorphous silicon (a-Si) thin-film PV modules for application in utility-interactive systems. Stand-alone PV systems began receiving increased emphasis at the SE RES in 1986. Research projects were initiated that involved evaluation of vaccine refrigeration, water pumping and other stand-alone power systems. The results of this work have led to design optimization techniques and procedures for the sizing and modeling of PV water pumping systems. Later recent research at the SE RES included test and evaluation of batteries and charge controllers for stand-alone PV system applications. The SE RES project provided the foundation on which FSEC achieved national recognition for its expertise in PV systems research and related technology transfer programs. These synergistic products of the SE RES illustrate the high visibility and contributions the FSEC PV program offers to the DOE.

Visible/infrared radiometric calibration station  

Science Conference Proceedings (OSTI)

We have begun construction of a visible/infrared radiometric calibration station that will allow for absolute calibration of optical and IR remote sensing instruments with clear apertures less than 16 inches in diameter in a vacuum environment. The calibration station broadband sources will be calibrated at the National Institute of Standards and Technology (NIST) and allow for traceable absolute radiometric calibration to within {plus_minus}3% in the visible and near IR (0.4--2.5 {mu}m), and less than {plus_minus}1% in the infrared, up to 12 {mu}m. Capabilities for placing diffraction limited images or for sensor full-field flooding will exist. The facility will also include the calibration of polarization and spectral effects, spatial resolution, field of view performance, and wavefront characterization. The configuration of the vacuum calibration station consists of an off-axis 21 inch, f/3.2, parabolic collimator with a scanning fold flat in collimated space. The sources are placed, via mechanisms to be described, at the focal plane of the off-axis parabola. Vacuum system pressure will be in the 10{sup {minus}6} Torr range. The broadband white-light source is a custom design by LANL with guidance from Labsphere Inc. The continuous operating radiance of the integrating sphere will be from 0.0--0.006 W/cm{sup 2}/Sr/{mu}m (upper level quoted for {approximately}500 nm wavelength). The blackbody source is also custom designed at LANL with guidance from NIST. The blackbody temperature will be controllable between 250--350{degrees}K. Both of the above sources have 4.1 inch apertures with estimated radiometric instability at less than 1%. The designs of each of these units will be described.

Waste heat rejection from geothermal power stations  

DOE Green Energy (OSTI)

Waste heat rejection systems for geothermal power stations have a significantly greater influence on plant operating performances and costs than do corresponding systems in fossil- and nuclear-fueled stations. With thermal efficiencies of only about 10%, geothermal power cycles can reject four times as much heat per kilowatt of output. Geothermal sites in the United States tend to be in water-short areas that could require use of more expensive wet/dry or dry-type cooling towers. With relatively low-temperature heat sources, the cycle economics are more sensitive to diurnal and seasonal variations in sink temperatures. Factors such as the necessity for hydrogen sulfide scrubbers in off-gas systems or the need to treat cooling tower blowdown before reinjection can add to the cost and complexity of goethermal waste heat rejection systems. Working fluids most commonly considered for geothermal cycles are water, ammonia, Freon-22, isobutane, and isopentane. Both low-level and barometric-leg direct-contact condensers are used, and reinforced concrete has been proposed for condenser vessels. Multipass surface condensers also have wide application. Corrosion problems at some locations have led to increased interest in titanium tubing. Studies at ORNL indicate that fluted vertical tubes can enhance condensing film coefficients by factors of 4 to 7.

Waste heat rejection from geothermal power stations  

DOE Green Energy (OSTI)

This study of waste heat rejection from geothermal power stations is concerned only with the heat rejected from the power cycle. The heat contained in reinjected or otherwise discharged geothermal fluids is not included with the waste heat considered here. The heat contained in the underflow from the flashtanks in such systems is not considered as part of the heat rejected from the power cycle. By following this definition of the waste heat to be rejected, various methods of waste heat dissipation are discussed without regard for the particular arrangement to obtain heat from the geothermal source. Recent conceptual design studies made for 50-MW(e) geothermal power stations at Heber and Niland, California, are of particular interst. The former uses a flashed-steam system and the latter a binary cycle that uses isopentane. In last-quarter 1976 dollars, the total estimated capital costs were about $750/kW and production costs about 50 mills/kWhr. If wet/dry towers were used to conserve 50% of the water evaporation at Heber, production costs would be about 65 mills/kWhr.

Physics Research on the International Space Station  

E-Print Network (OSTI)

The International Space Station (ISS) is orbiting Earth at an altitude of around 400 km. It has been manned since November 2000 and currently has a permanent crew of six. On-board ISS science is done in a wide field of sciences, from fundamental physics to biology and human physiology. Many of the experiments utilize the unique conditions of weightlessness, but also the views of space and the Earth are exploited. ESAs (European Space Agency) ELIPS (European Programme Life and Physical sciences in Space) manages some 150 on-going and planned experiments for ISS, which is expected to be utilized at least to 2020. This presentation will give a short introduction to ISS, followed by an overview of the science field within ELIPS and some resent results.

Resilient design of recharging station networks for electric transportation vehicles  

DOE Green Energy (OSTI)

As societies shift to 'greener' means of transportation using electricity-driven vehicles one critical challenge we face is the creation of a robust and resilient infrastructure of recharging stations. A particular issue here is the optimal location of service stations. In this work, we consider the placement of battery replacing service station in a city network for which the normal traffic flow is known. For such known traffic flow, the service stations are placed such that the expected performance is maximized without changing the traffic flow. This is done for different scenarios in which roads, road junctions and service stations can fail with a given probability. To account for such failure probabilities, the previously developed facility interception model is extended. Results show that service station failures have a minimal impact on the performance following robust placement while road and road junction failures have larger impacts which are not mitigated easily by robust placement.

Determining Yankee Nuclear Power Station neutron activation  

Science Conference Proceedings (OSTI)

The Yankee nuclear power station located in Rowe, Massachusetts, permanently ceased power operations on February 26, 1992, after 31 yr of operation. Yankee has since initiated decommissioning planning activities. A significant component of these activities is a determination of the extent of radiological contamination of the Yankee site. Included in this effort was determination of the extent of neutron activation of plant components. This paper describes the determination of the neutron activation of the Yankee reactor vessel, associated internals, and surrounding structures. The Yankee reactor vessel is a 600-MW(thermal) stainless steel-lined, carbon steel vessel with stainless steel internal components designed by Westinghouse. The reactor vessel is surrounded and supported by a carbon steel neutron shield tank that was filled with chromated water during plant operation. A 5-ft-thick concrete biological shield wall surrounds the neutron shield tank. A project is under way to remove the reactor vessel internals from the reactor vessel.

Yankee has since initiated decommissioning planning activities. A significant component of these activities is the determination of the extent of radiological contamination of the Yankee site. This paper describes the site radiological characterization program that has been implemented for decommissioning the Yankee plant. Radiological scoping surveys were completed to support submittal of a decommissioning plan to the U.S. Nuclear Regulatory Commission (NRC) by October 1, 1993. These surveys were designed to provide sufficient detail to estimate the extent of contamination, volume of radiological waste, activity of radiological waste, and personnel dose estimates for removal activities. Surveys were conducted both inside and on the grounds outside of the Yankee plant buildings. Survey results were combined with analytical evaluations to characterize the Yankee site.

Unique portable signal acquisition/processing station  

SciTech Connect

At Lawrence Livermore National Laboratory, there are experimental applications requiring digital signal acquisition as well as data reduction and analysis. A prototype Signal Acquisition/Processing Station (SAPS) has been constructed and is currently undergoing tests. The system employs an LSI-11/23 computer with Data Translation analog-to-digital hardware. SAPS is housed in a roll-around cart which has been designed to withstand most subtle EMI/RFI environments. A user-friendly menu allows a user to access powerful data acquisition packages with a minimum of training. The software architecture of SAPS involves two operating systems, each being transparent to the user. Since this is a general purpose workstation with several units being utilized, an emphasis on low cost, reliability, and maintenance was stressed during conception and design. The system is targeted for mid-range frequency data acquisition; between a data logger and a transient digitizer.

Solar Powered Radioactive Air Monitoring Stations  

SciTech Connect

Environmental monitoring of ambient air for radioactive material is required as stipulated in the PNNL Site radioactive air license. Sampling ambient air at identified preferred locations could not be initially accomplished because utilities were not readily available. Therefore, solar powered environmental monitoring systems were considered as a possible option. PNNL purchased two 24-V DC solar powered environmental monitoring systems which consisted of solar panels, battery banks, and sampling units. During an approximate four month performance evaluation period, the solar stations operated satisfactorily at an on-site test location. They were subsequently relocated to their preferred locations in June 2012 where they continue to function adequately under the conditions found in Richland, Washington.

Final environmental assessment for vegetation control at VHF stations, microwave stations, electrical substations, and pole yards  

Science Conference Proceedings (OSTI)

Southwestern Power Adm. operates very high frequency (VHF) and microwave radio stations, electrical substations, and pole yards for electric power transmission throughout AR, MO, and OK. Vegetation growth at the stations must be suppressed for safety of operation and personnel. Southwestern has been using a combination of mechanical/manual and herbicide control for this purpose; Federally- mandated reductions in staff and budgetary resources require Southwestern to evaluate all potentially efficient methods for vegetation control. Three alternatives were examined: no action, mechanical/manual control, and (proposed) a combination of mechanical/manual and herbicide control. Environmental impacts on air and water quality, wetlands, wildlife, endangered species, archaeological and other resources, farmland, human health, transportation, etc. were evaluated.

Validation of an Integrated Hydrogen Energy Station  

SciTech Connect

This report presents the results of a 10-year project conducted by Air Products and Chemicals, Inc. (Air Products) to determine the feasibility of coproducing hydrogen with electricity. The primary objective was to demonstrate the technical and economic viability of a hydrogen energy station using a high-temperature fuel cell designed to produce power and hydrogen. This four-phase project had intermediate go/no-go decisions and the following specific goals: ?¢???¢ Complete a technical assessment and economic analysis of the use of high-temperature fuel cells, including solid oxide and molten carbonate, for the co-production of power and hydrogen (energy park concept). ?¢???¢ Build on the experience gained at the Las Vegas H2 Energy Station and compare/contrast the two approaches for co-production. ?¢???¢ Determine the applicability of co-production from a high-temperature fuel cell for the existing merchant hydrogen market and for the emerging hydrogen economy. ?¢???¢ Demonstrate the concept on natural gas for six months at a suitable site with demand for both hydrogen and electricity. ?¢???¢ Maintain safety as the top priority in the system design and operation. ?¢???¢ Obtain adequate operational data to provide the basis for future commercial activities, including hydrogen fueling stations. Work began with the execution of the cooperative agreement with DOE on 30 September 2001. During Phase 1, Air Products identified high-temperature fuel cells as having the potential to meet the coproduction targets, and the molten carbonate fuel cell system from FuelCell Energy, Inc. (FuelCell Energy) was selected by Air Products and DOE following the feasibility assessment performed during Phase 2. Detailed design, construction and shop validation testing of a system to produce 250 kW of electricity and 100 kilograms per day of hydrogen, along with site selection to include a renewable feedstock for the fuel cell, were completed in Phase 3. The system also completed six months of demonstration operation at the wastewater treatment facility operated by Orange County Sanitation District (OCSD, Fountain Valley, CA). As part of achieving the objective of operating on a renewable feedstock, Air Products secured additional funding via an award from the California Air Resources Board. The South Coast Air Quality Management District also provided cost share which supported the objectives of this project. System operation at OCSD confirmed the results from shop validation testing performed during Phase 3. Hydrogen was produced at rates and purity that met the targets from the system design basis, and coproduction efficiency exceeded the 50% target set in conjunction with input from the DOE. Hydrogen production economics, updated from the Phase 2 analysis, showed pricing of $5 to $6 per kilogram of hydrogen using current gas purification systems. Hydrogen costs under $3 per kilogram are achievable if next-generation electrochemical separation technologies become available.

A computer program for HVDC converter station RF noise calculations  

SciTech Connect

HVDC converter station operations generate radio frequency (RF) electromagnetic (EM) noise which could interfere with adjacent communication and computer equipment, and carrier system operations. A generic Radio Frequency Computer Analysis Program (RAFCAP) for calculating the EM noise generated by valve ignition of a converter station has been developed as part of a larger project. The program calculates RF voltages, currents, complex power, ground level electric field strength and magnetic flux density in and around an HVDC converter station. The program requires the converter station network to be represented by frequency dependent impedance functions. Comparisons of calculated and measured values are given for an actual HVDC station to illustrate the validity of the program. RAFCAP is designed to be used by engineers for the purpose of calculating the RF noise produced by the igniting of HVDC converter valves.

Irradiation Environment of the Materials Test Station  

SciTech Connect

Conceptual design of the proposed Materials Test Station (MTS) at the Los Alamos Neutron Science Center (LANSCE) is now complete. The principal mission is the irradiation testing of advanced fuels and materials for fast-spectrum nuclear reactor applications. The neutron spectrum in the fuel irradiation region of MTS is sufficiently close to that of fast reactor that MTS can match the fast reactor fuel centerline temperature and temperature profile across a fuel pellet. This is an important characteristic since temperature and temperature gradients drive many phenomena related to fuel performance, such as phase stability, stoichiometry, and fission product transport. The MTS irradiation environment is also suitable in many respects for fusion materials testing. In particular, the rate of helium production relative to atomic displacements at the peak flux position in MTS matches well that of fusion reactor first wall. Nuclear transmutation of the elemental composition of the fusion alloy EUROFER97 in MTS is similar to that expected in the first wall of a fusion reactor.

Oak Ridge National Laboratory (ORNL) has been awarded $6.8 million in the Department of Energy (DOE) American Recovery and Reinvestment Act (ARRA) funds as part of an overall $114.8 million ECOtality grant with matching funds from regional partners to install 125 solar-assisted Electric Vehicle (EV) charging stations across Knoxville, Nashville, Chattanooga, and Memphis. Significant progress has been made toward completing the scope with the installation of 25 solar-assisted charging stations at ORNL; six stations at Electric Power Research Institute (EPRI); and 27 stations at Nissan's Smyrna and Franklin sites, with three more stations under construction at Nissan's new lithium-ion battery plant. Additionally, the procurement process for contracting the installation of 34 stations at Knoxville, the University of Tennessee Knoxville (UTK), and Nashville sites is underway with completion of installation scheduled for early 2012. Progress is also being made on finalizing sites and beginning installations of 30 stations in Nashville, Chattanooga, and Memphis by EPRI and Tennessee Valley Authority (TVA). The solar-assisted EV charging station project has made great strides in fiscal year 2011. A total of 58 solar-assisted EV parking spaces have been commissioned in East and Middle Tennessee, and progress on installing the remaining 67 spaces is well underway. The contract for the 34 stations planned for Knoxville, UTK, and Nashville should be underway in October with completion scheduled for the end of March 2012; the remaining three Nissan stations are under construction and scheduled to be complete in November; and the EPRI/TVA stations for Chattanooga, Vanderbilt, and Memphis are underway and should be complete by the end of March 2012. As additional Nissan LEAFs are being delivered, usage of the charging stations has increased substantially. The project is on course to complete all 125 solar-assisted EV charging stations in time to collect meaningful data by the end of government fiscal year 2012. Lessons learned from the sites completed thus far are being incorporated and are proving to be invaluable in completion of the remaining sites.

Application of a multi-block CFD code to investigate the impact of geometry modeling on centrifugal compressor flow field predictions  

Science Conference Proceedings (OSTI)

CFD codes capable of utilizing multi-block grids provide the capability to analyze the complete geometry of centrifugal compressors. Attendant with this increased capability is potentially increased grid setup time and more computational overhead with the resultant increase in wall clock time to obtain a solution. If the increase in difficulty of obtaining a solution significantly improves the solution from that obtained by modeling the features of the tip clearance flow or the typical bluntness of a centrifugal compressor`s trailing edge, then the additional burden is worthwhile. However, if the additional information obtained is of marginal use, then modeling of certain features of the geometry may provide reasonable solutions for designers to make comparative choices when pursuing a new design. In this spirit a sequence of grids were generated to study the relative importance of modeling versus detailed gridding of the tip gap and blunt trailing edge regions of the NASA large low-speed centrifugal compressor for which there is considerable detailed internal laser anemometry data available for comparison. The results indicate: (1) There is no significant difference in predicted tip clearance mass flow rate whether the tip gap is gridded or modeled. (2) Gridding rather than modeling the trailing edge results in better predictions of some flow details downstream of the impeller, but otherwise appears to offer no great benefits. (3) The pitchwise variation of absolute flow angle decreases rapidly up to 8% impeller radius ratio and much more slowly thereafter. Although some improvements in prediction of flow field details are realized as a result of analyzing the actual geometry there is no clear consensus that any of the grids investigated produced superior results in every case when compared to the measurements. However, if a multi-block code is available, it should be used, as it has the propensity for enabling better predictions than a single block code.

OPTIMIZING PERFORMANCE OF THE HESKETT STATION  

SciTech Connect

The overall conclusion from this work is that a switch from river sand bed material to limestone at the R.M. Heskett Station would provide substantial benefits to MDU. A switch to limestone would increase the fuel flexibility of the unit, allowing fuels higher in both sodium and sulfur to be burned. The limestone bed can tolerate a much higher buildup of sodium in the bed without agglomeration, allowing either the bed turnover rate to be reduced to half the current sand feed rate for a fuel with equivalent sodium or allow a higher sodium fuel to be burned with limestone feed rates equivalent to the current sand feed rate. Both stack and ambient SO{sub 2} emissions can be controlled. A small improvement in boiler efficiency should be achievable by operating at lower excess oxygen levels at low load. This reduction in oxygen will also lower NO{sub x} emissions, providing a margin of safety for meeting emission standards. No detrimental effects of using limestone at the Heskett Station were uncovered as a result of the test burn. Some specific conclusions from this work include the following: The bed material feed rate can be reduced from the current rate of 5.4% of the coal feed rate (57.4 tons of sand/day) to 2.5% of the coal feed rate (27 tons of limestone/day). This will result in an annual savings of approximately $200,000. (1) SO{sub 2} emissions at the recommended feed rate would be approximately 250 ppm (0.82 lb/MMBtu) using a similar lignite. Based on the cost of the limestones, SO{sub 2} allowances could be generated at a cost of $60/ton SO{sub 2} , leaving a large profit margin for the sale of allowances. The addition of limestone at the same rate currently used for sand feed could generate $455,000 net income if allowances are sold at $200/ton SO2 . (2) At full-load operation, unburned carbon losses increase significantly at excess oxygen levels below 2.8%. No efficiency gains are expected at high-load operation by switching from sand to limestone. By reducing the oxygen level at low load to 8.5%, an efficiency gain of approximately 1.2% could be realized, equating to $25,000 to $30,000 in annual savings. (3) A reduction of 25 tons/day total ash (bed material plus fly ash) will be realized by using limestone at the recommended feed rate compared to the current sand feed rate. No measurable change in volume would be realized because of the lower bulk density of the limestone-derived material.

Southwest Region Experiment Station 1988 report  

DOE Green Energy (OSTI)

The highlights of tasks performed during 1988 by staff members at the Southwest Region Experiment Station (SWRES) are summarized in this report. During 1988, our staff tested and evaluated photovoltaic systems, designed hardware for data acquisition systems, developed software for data analysis, and demonstrated the uses of Photovoltaics (PVs) to the public. Field evaluations of stand-alone and grid-connected systems were a major project for the SWRES in 1988. The goal was to determine the reliability of PV systems, to identif
