The sensors that collect the core variables are mounted at the standard heights defined for each variable: • Winds: 10 meters • Temperature and Relative Humidity: 2 meters • Barometric Pressure: 1 meter. Depending upon the geographical location, different models and types of sensors may be used to measure the core variables due to the conditions experienced at those locations. Most sites have additional sensors that measure other variables that are unique to that site or are well suited for the climate of the location but not at others.

Comparison of Triton SODAR Data to Meteorological Tower Wind Measurement Data in Hebei Province, China  

DOE Green Energy (OSTI)

With the increased interest in remote sensing of wind information in recent years, it is important to determine the reliability and accuracy of new wind measurement technologies if they are to replace or supplement conventional tower-based measurements. In view of this, HydroChina Corporation and the United States National Renewable Energy Laboratory (NREL) conducted a comparative test near a wind farm in Hebei Province, China. We present the results of an analysis characterizing the measurement performance of a state-of-the-art Sound Detection and Ranging (sodar) device when compared to a traditional tower measurement program. NREL performed the initial analysis of a three-month period and sent the results to HydroChina. When another month of data became available, HydroChina and their consultant Beijing Millenium Engineering Software (MLN) repeated NREL's analysis on the complete data set, also adding sensitivity analysis for temperature, humidity, and wind speed (Section 6). This report presents the results of HydroChina's final analysis of the four-month period.

Introduction to meteorological measurements and data handling for solar energy applications. Task IV-Development of an insolation handbook and instrument package  

DOE Green Energy (OSTI)

Recognizing a need for a coordinated approach to resolve energy problems, certain members of the Organization for Economic Cooperation and Development (OECD) met in September 1974 and agreed to develop an International Energy Program. The International Energy Agency (IEA) was established within the OECD to administer, monitor and execute this International Energy Program. In July 1975, Solar Heating and Cooling was selected as one of the sixteen technology fields for multilateral cooperation. Five project areas, called tasks, were identified for cooperative activities within the IEA Program to Develop and Test Solar Heating and Cooling Systems. The objective of one task was to obtain improved basic resource information for the design and operation of solar heating and cooling systems through a better understanding of the required insolation (solar radiation) and related weather data, and through improved techniques for measurement and evaluation of such data. At the February 1976 initial experts meeting in Norrkoeping, Sweden, the participants developed the objective statement into two subtasks. (1) an insolation handbook; and (2) a portable meteorological instrument package. This handbook is the product of the first subtask. The objective of this handbook is to provide a basis for a dialogue between solar scientists and meteorologists. Introducing the solar scientist to solar radiation and related meteorological data enables him to better express his scientific and engineering needs to the meteorologist; and introducing the meteorologist to the special solar radiation and meteorological data applications of the solar scientist enables him to better meet the needs of the solar energy community.

Automated data system for emergency meteorological response  

SciTech Connect

The Savannah River Plant (SRP) releases small amounts of radioactive nuclides to the atmosphere as a consequence of the production of radioisotopes. The potential for larger accidental releases to the atmosphere also exists, although the probability for most accidents is low. To provide for emergency meteorological response to accidental releases and to conduct research on the transport and diffusion of radioactive nuclides in the routine releases, a series of high-quality meteorological sensors have been located on towers in and about SRP. These towers are equipped with instrumentation to detect and record temperature and wind turbulence. Signals from the meterological sensors are brought by land-line to the SRL Weather Center-Analysis Laboratory (WC-AL). At the WC-AL, a Weather Information and Display (WIND) system has been installed. The WIND system consists of a minicomputer with graphical displays in the WC-AL and also in the emergency operating center (EOC) of SRP. In addition, data are available to the system from standard weather teletype services, which provide both routine surface weather observations and routine upper air wind and temperature observations for the southeastern United States. Should there be an accidental release to the atmosphere, available recorded data and computer codes would allow the calculation and display of the location, time, and downwind concentration of the atmospheric release. These data are made available to decision makers in near real-time to permit rapid decisive action to limit the consequences of such accidental releases. (auth)

Meteorological Observations for Renewable Energy Applications at Site 300  

DOE Green Energy (OSTI)

In early October 2010, two Laser and Detection Ranging (LIDAR) units (LIDAR-96 and LIDAR-97), a 3 m tall flux tower, and a 3 m tall meteorological tower were installed in the northern section of Site 300 (Figure 1) as a first step in development of a renewable energy testbed facility. This section of the SMS project is aimed at supporting that effort with continuous maintenance of atmospheric monitoring instruments capable of measuring vertical profiles of wind speed and wind direction at heights encountered by future wind power turbines. In addition, fluxes of energy are monitored to estimate atmospheric mixing and its effects on wind flow properties at turbine rotor disk heights. Together, these measurements are critical for providing an accurate wind resource characterization and for validating LLNL atmospheric prediction codes for future renewable energy projects at Site 300. Accurate, high-resolution meteorological measurements of wind flow in the planetary boundary layer (PBL) and surface-atmosphere energy exchange are required for understanding the properties and quality of available wind power at Site 300. Wind speeds at heights found in a typical wind turbine rotor disk ({approx} 40-140 m) are driven by the synergistic impacts of atmospheric stability, orography, and land-surface characteristics on the mean wind flow in the PBL and related turbulence structures. This section of the report details the maintenance and labor required in FY11 to optimize the meteorological instruments and ensure high accuracy of their measurements. A detailed look at the observations from FY11 is also presented. This portion of the project met the following milestones: Milestone 1: successful maintenance and data collection of LIDAR and flux tower instruments; Milestone 2: successful installation of solar power for the LIDAR units; and Milestone 3: successful implementation of remote data transmission for the LIDAR units.

Optimal sequencing of a cooling tower with multiple cells  

E-Print Network (OSTI)

This paper evaluates the energy savings potential of multi-cell cooling tower optimal sequencing control methods. Annual tower fan energy usage is calculated for a counter-flow tower with multiple variable-speed fans. Effectiveness-NTU tower model is employed to predict the cooling tower performance at various conditions. Natural convection when the fan is off is accounted by using an assumed airflow rate. The energy savings at five cities representing different typical climates are studied using typical meteorological year data. The results show that, if the tower capacity can be increased by 50% and 100% by running extra tower cells, the annual total fan power usage can be reduced by 44% and 61%, respectively. A cumulative saving percent curve is generated to help estimate the annual total savings percent when extra cooling tower capacity is available during only part of a year.

Stability and Turbulence in the Atmospheric Boundary Layer: A Comparison of Remote Sensing and Tower Observations  

Science Conference Proceedings (OSTI)

When monitoring winds and atmospheric stability for wind energy applications, remote sensing instruments present some advantages to in-situ instrumentation such as larger vertical extent, in some cases easy installation and maintenance, measurements of vertical humidity profiles throughout the boundary layer, and no restrictions on prevailing wind directions. In this study, we compare remote sensing devices, Windcube lidar and microwave radiometer, to meteorological in-situ tower measurements to demonstrate the accuracy of these measurements and to assess the utility of the remote sensing instruments in overcoming tower limitations. We compare temperature and wind observations, as well as calculations of Brunt-Vaisala frequency and Richardson numbers for the instrument deployment period in May-June 2011 at the U.S. Department of Energy National Renewable Energy Laboratory's National Wind Technology Center near Boulder, Colorado. The study reveals that a lidar and radiometer measure wind and temperature with the same accuracy as tower instruments, while also providing advantages for monitoring stability and turbulence. We demonstrate that the atmospheric stability is determined more accurately when the liquid-water mixing ratio derived from the vertical humidity profile is considered under moist-adiabatic conditions.

The Florida Footprint experiments were a series of field programs in which perfluorocarbon tracers were released in different configurations centered on a flux tower to generate a data set that can be used to test transport and dispersion models. These models are used to determine the sources of the CO{sub 2} that cause the fluxes measured at eddy covariance towers. Experiments were conducted in a managed slash pine forest, 10 km northeast of Gainesville, Florida, in 2002, 2004, and 2006 and in atmospheric conditions that ranged from well mixed, to very stable, including the transition period between convective conditions at midday to stable conditions after sun set. There were a total of 15 experiments. The characteristics of the PFTs, details of sampling and analysis methods, quality control measures, and analytical statistics including confidence limits are presented. Details of the field programs including tracer release rates, tracer source configurations, and configuration of the samplers are discussed. The result of this experiment is a high quality, well documented tracer and meteorological data set that can be used to improve and validate canopy dispersion models.

NREL National Wind Technology Center (NWTC): M2 Tower; Boulder, Colorado (Data)  

DOE Data Explorer (OSTI)

The National Wind Technology Center (NWTC), located at the foot of the Rocky Mountains near Boulder, Colorado, is a world-class research facility managed by NREL for the U.S. Department of Energy. NWTC researchers work with members of the wind energy industry to advance wind power technologies that lower the cost of wind energy through research and development of state-of-the-art wind turbine designs. NREL's Measurement and Instrument Data Center provides data from NWTC's M2 tower which are derived from instruments mounted on or near an 82 meter (270 foot) meteorological tower located at the western edge of the NWTC site and about 11 km (7 miles) west of Broomfield, and approximately 8 km (5 miles) south of Boulder, Colorado. The data represent the mean value of readings taken every two seconds and averaged over one minute. The wind speed and direction are measured at six heights on the tower and air temperature is measured at three heights. The dew point temperature, relative humidity, barometric pressure, totalized liquid precipitation, and global solar radiation are also available.

Cooling tower waste reduction  

SciTech Connect

At Lawrence Livermore National Laboratory (LLNL), the two main cooling tower systems (central and northwest) were upgraded during the summer of 1997 to reduce the generation of hazardous waste. In 1996, these two tower systems generated approximately 135,400 lbs (61,400 kg) of hazardous sludge, which is more than 90 percent of the hazardous waste for the site annually. At both, wet decks (cascade reservoirs) were covered to block sunlight. Covering the cascade reservoirs reduced the amount of chemical conditioners (e.g. algaecide and biocide), required and in turn the amount of waste generated was reduced. Additionally, at the northwest cooling tower system, a sand filtration system was installed to allow cyclical filtering and backflushing, and new pumps, piping, and spray nozzles were installed to increase agitation. the appurtenance upgrade increased the efficiency of the cooling towers. The sand filtration system at the northwest cooling tower system enables operators to continuously maintain the cooling tower water quality without taking the towers out of service. Operational costs (including waste handling and disposal) and maintenance activities are compared for the cooling towers before and after upgrades. Additionally, the effectiveness of the sand filter system in conjunction with the wet deck covers (northwest cooling tower system), versus the cascade reservoir covers alone (south cooling tower south) is discussed. the overall expected return on investment is calculated to be in excess of 250 percent. this upgrade has been incorporated into the 1998 DOE complex-wide water conservation project being led by Sandia National Laboratory/Albuquerque.

The Damaging Effects of Earthquake Excitation on Concrete Cooling Towers  

SciTech Connect

Reinforced concrete cooling towers of hyperbolic shell configuration find widespread application in utilities engaged in the production of electric power. In design of critical civil infrastructure of this type, it is imperative to consider all the possible loading conditions that the cooling tower may experience, an important loading condition in many countries is that of the earthquake excitation, whose influence on the integrity and stability of cooling towers is profound. Previous researches have shown that the columns supporting a cooling tower are sensitive to earthquake forces, as they are heavily loaded elements that do not possess high ductility, and understanding the behavior of columns under earthquake excitation is vital in structural design because they provide the load path for the self weight of the tower shell. This paper presents the results of a finite element investigation of a representative 'dry' cooling tower, using realistic horizontal and vertical acceleration data obtained from the recent and widely-reported Tabas, Naghan and Bam earthquakes in Iran. The results of both linear and nonlinear analyses are reported in the paper, the locations of plastic hinges within the supporting columns are identified and the ramifications of the plastic hinges on the stability of the cooling tower are assessed. It is concluded that for the (typical) cooling tower configuration analyzed, the columns that are instrumental in providing a load path are influenced greatly by earthquake loading, and for the earthquake data used in this study the representative cooling tower would be rendered unstable and would collapse under the earthquake forces considered.

Cooling Towers, The Debottleneckers  

E-Print Network (OSTI)

Power generating plants and petro-chemical works are always expanding. An on-going problem is to identify and de-bottle neck restricting conditions of growth. The cooling tower is a highly visible piece of equipment. Most industrial crossflow units are large structures, Illustration 1. Big budget money and engineering time goes into gleaming stainless steel equipment and exotic process apparatus, the poor cooling tower is the ignored orphan of the system. Knowledgeable Engineers, however, are now looking into the function of the cooling tower, which is to produce colder water- and question the quality of water discharged from that simple appearing box. These cross-flow structures are quite large, ranging up to 60 feet tall with as many as 6 or more cells in a row. With cells up to 42 feet long so immense in aspect, with fans rotating, operators assume, just by appearances, that all is well, and usually pay no attention to the quality of cold water returning from the cooling tower. The boxes look sturdy, but the function of the cooling tower is repeated ignored production of water as cold as possible.

Solar power towers  

DOE Green Energy (OSTI)

The high desert near Barstow, California, has witnessed the development of this country`s first two solar power towers. Solar One operated successfully from 1982 to 1988 and proved that power towers work efficiently to produce utility-scale power from sunlight. Solar Two was connected to the utility grid in 1996 and is operating today. Like its predecessor, Solar Two is rated at 10 megawatts. An upgrade of the Solar One plant, Solar Two demonstrates how solar energy can be stored in the form of heat in molten salt for power generation on demand. The experience gained with these two pilot power towers has established a foundation on which industry can develop its first commercial plants. These systems produce electricity on a large scale. They are unique among solar technologies because they can store energy efficiently and cost effectively. They can operate whenever the customer needs power, even after dark or during cloudy weather.

Guangzhou West Tower is an extremely tall public building. The energy efficiency evaluation of its façade should be different than that of ordinary public buildings. Based on the national code GB50189-2005, “Design Standard for Energy efficiency of Public Buildings”, typical meteorological yearly data for Guangzhou were used and revised according to architectural character of Guangzhou West Tower. The energy efficiency design of a single skin façade and active airflow curtain wall was analyzed by a dynamic energy simulation tool and modified weather data. The payback period of initial investment in the façade system was evaluated based on simulation results. In addition, the results confirm the façade system scheme of Guangzhou West Tower.

Abstract On the Automorphism Tower  

E-Print Network (OSTI)

In this thesis I study the automorphism tower of free nilpotent groups. Our main tool in studying the automorphism tower is to embed every group as a lattice in some Lie group. Using known rigidity results the automorphism group of the discrete group can be embedded into the automorphism group of the Lie group. This allows me to lift the description of the derivation tower of the free nilpotent Lie algebra to obtain information about the automorphism tower of the free nilpotent group. The main result in this thesis states that the automorphism tower of the free nilpotent group ?(n, d) on n generators and nilpotency class d, stabilizes after finitely many steps. If the nilpotency class is small compared to the number of generators we have that the height of the automorphism tower is at most

Cooling Towers, Energy Conservation Strategies  

E-Print Network (OSTI)

Cooling towers, because of their seeming simplicity, are usually orphans of the facilities operation. We are all aware that cooling towers are the step-children of the chemical process plant, electric power generating station, and refrigeration system. While our engineers are pretty well convinced of the importance of their sophisticated equipment, and rightly so, they take the cooling towers and the cold water returning from them for granted. Design Conditions are specified for the particular requirements before a cooling tower is purchased. After it is put on the line and the cold water temperature or volume becomes inadequate, they look to solutions other than the obvious. While all cooling towers are purchased to function at 100% of capability in accordance with the required Design Conditions, in actual on stream employment, the level of operation many times is lower, downwards to as much as 50% due to a variety of reasons: (1) The present service needed is now greater than the original requirements which the tower was purchased for; (2) 'Slippage' due to usage and perhaps deficient maintenance has reduced the performance of the tower over years of operation; (3) The installation could have been originally undersized due to the low bidder syndrome; and (4) New plant expansion needs colder temperatures off the tower.

Thermal performance of cooling towers  

SciTech Connect

Wet cooling towers are often used in HVAC applications to reject heat to the atmosphere. Heat rejection is accomplished within the tower by heat and mass transfer between hot water droplets and ambient air. These heat and mass transfer processes and the resulting coefficient of performance are often misunderstood and misinterpreted. To demystify these concepts, the heat and mass transfer exchange at the water droplet level are reviewed. This is followed by an analysis of an idealized spray-type tower to show how cooling tower performance is affected by fill height, water retention time, and air and water mass flow rates. Finally, the so-called coefficient of performance of cooling towers is examined.

SMUD Kokhala Power Tower Study  

DOE Green Energy (OSTI)

Kokhala is the name of a new hybridized power tower design which integrates a nitrate-salt solar power tower with a gas turbine combined-cycle power plant. This integration achieves high value energy, low costs, and lower investor risk than a conventional solar only power tower plant. One of the primary advantages of this system is that it makes small power tower plants much more economically competitive with conventional power generation technologies. This paper is an overview of a study that performed a conceptual evaluation of a small (30 MWe) commercial plant suitable for the Sacramento Municipal Utility District`s (SMUD) Rancho Seco power plant site near Sacramento, California. This paper discusses the motivation for using a small hybrid solar plant and provides an overview of the analysis methodology used in the study. The results indicate that a power tower integrated with an advanced gas turbine, combined with Sacramento`s summer solar resource, could produce a low- risk, economically viable power generation project in the near future.

Oriented spray-assisted cooling tower  

Science Conference Proceedings (OSTI)

Apparatus useful for heat exchange by evaporative cooling when employed in conjunction with a conventional cooling tower. The arrangement includes a header pipe which is used to divert a portion of the water in the cooling tower supply conduit up stream of the cooling tower to a multiplicity of vertical pipes and spray nozzles which are evenly spaced external to the cooling tower so as to produce a uniform spray pattern oriented toward the central axis of the cooling tower and thereby induce an air flow into the cooling tower which is greater than otherwise achieved. By spraying the water to be cooled towards the cooling tower in a region external to the cooling tower in a manner such that the spray falls just short of the cooling tower basin, the spray does not interfere with the operation of the cooling tower, proper, and the-maximum increase in air velocity is achieved just above the cooling tower basin where it is most effective. The sprayed water lands on a concrete or asphalt apron which extends from the header pipe to the cooling tower basin and is gently sloped towards the cooling tower basin such that the sprayed water drains into the basin. By diverting a portion of the water to be cooled to a multiplicity of sprays external to the cooling tower, thermal performance is improved. 4 figs.

Hydrogen Storage in Wind Turbine Towers  

DOE Green Energy (OSTI)

Low-cost hydrogen storage is recognized as a cornerstone of a renewables-hydrogen economy. Modern utility-scale wind turbine towers are typically conical steel structures that, in addition to supporting the rotor, could be used to store hydrogen. This study has three objectives: (1) Identify the paramount considerations associated with using a wind turbine tower for hydrogen storage; (2)Propose and analyze a cost-effective design for a hydrogen-storing tower; and (3) Compare the cost of storage in hydrogen towers to the cost of storage in conventional pressure vessels. The paramount considerations associated with a hydrogen tower are corrosion (in the form of hydrogen embrittlement) and structural failure (through bursting or fatigue life degradation). Although hydrogen embrittlement (HE) requires more research, it does not appear to prohibit the use of turbine towers for hydrogen storage. Furthermore, the structural modifications required to store hydrogen in a tower are not cost prohibitive.

Cooling Tower Inspection with Scuba  

E-Print Network (OSTI)

A serious problem of scale and other solid material settling in heat transfer equipment was threatening to shut down our ethylene plant. All evidence pointed to the cooling tower as the source of the contamination. Visual inspection of the cooling tower pump suction basin was accomplished by diving into the basin using SCUBA gear. It was possible to see a build-up of debris on the pump suction basket strainers and on the floor of the sumps. Also, it was discovered that one of the four baskets had been installed incorrectly. Photographs of the basket strainers were taken to aid in describing their exact condition. With the aid of SCUBA it was possible to sufficiently clean the pump sumps so that costly downtime was avoided. Likewise, using this technique, steps were taken to greatly reduce the chance for further contamination of the circulating cooling water system.

Mesoscale meteorological measurements characterizing complex flows  

Science Conference Proceedings (OSTI)

Meteorological measurements are an integral and essential component of any emergency response system for addressing accidental releases from nuclear facilities. An important element of the US Department of Energy`s (DOE`s) Atmospheric Studies in Complex Terrain (ASCOT) program is the refinement and use of state-of-the-art meteorological instrumentation. ASCOT is currently making use of ground-based remote wind sensing instruments such as doppler acoustic sounders (sodars). These instruments are capable of continuously and reliably measuring winds up to several hundred meters above the ground, unattended. Two sodars are currently measuring the winds, as part of ASCOT`s Front Range Study, in the vicinity of DOE`s Rocky Flats Plant (RFP) near Boulder, Colorado. A brief description of ASCOT`s ongoing Front Range Study is given followed by a case study analysis that demonstrates the utility of the meteorological measurement equipment and the complexity of flow phenomena that are experienced near RFP. These complex flow phenomena can significantly influence the transport of the released material and consequently need to be identified for accurate assessments of the consequences of a release.

Vortex-augmented cooling tower - windmill combination  

DOE Patents (OSTI)

A cooling tower for cooling large quantities of effluent water from a production facility by utilizing natural wind forces includes the use of a series of helically directed air inlet passages extending outwardly from the base of the tower to introduce air from any direction in a swirling vortical pattern while the force of the draft created in the tower makes it possible to place conventional power generating windmills in the air passage to provide power as a by-product.

Combined-cycle power tower  

DOE Green Energy (OSTI)

This paper evaluates a new power tower concept that offers significant benefits for commercialization of power tower technology. The concept uses a molten nitrate salt centralreceiver plant to supply heat, in the form of combustion air preheat, to a conventional combined-cycle power plant. The evaluation focused on first commercial plants, examined three plant capacities (31, 100, and 300 MWe), and compared these plants with a solar-only 100-MWe plant and with gas-only combined-cycle plants in the same three capacities. Results of the analysis point to several benefits relative to the solar-only plant including low energy cost for first plants, low capital cost for first plants, reduced risk with respect to business uncertainties, and the potential for new markets. In addition, the concept appears to have minimal technology development requirements. Significantly, the results show that it is possible to build a first plant with this concept that can compete with existing gas-only combined-cycle plants.

Influence of the meteorology mast on a cup anemometer  

Science Conference Proceedings (OSTI)

The actuator disc model is applied on lattice-type meteorological masts to estimate the influence of the tower on the accuracy of the measured wind speed. Combining the results with corrections for the boom, on which the anemometer is mounted, good agreement is found for measurements made on the mast at Tjoereborg. Iso-speed plots are computed to estimate the influence of different solidities. Depending on the distance from the mast and the solidity the influence from a typical mast is normally less than 3%.

Heat is rejected from the tower primarily through evaporation. Therefore, by design, cooling towers consume significant amounts of water. Overview The thermal efficiency and longevity of the cooling tower and equipment used to cool depend on the proper management of water recirculated through the tower.

Noise from cooling towers of power parks  

SciTech Connect

A study is presented of the noise pollution problem for large power parks proposed for the future. Such parks might have an area of about 75 sq. miles, and a generating capacity up to 48000 MW. A comparative analysis has been done for natural and mechanical-draft wet towers as the major sources of acoustic power. Noise radiation from single isolated towers as well as from a dispersed array of towers has been considered for both types of cooling systems. Major noise attenuation effects considered are due to the atmospheric absorption and A- weighting. Conditions of 60F and 70 percent relative humidity in a still atmosphere have been assumed. (auth)

Cooling Tower Considerations for Energy Optimizations  

E-Print Network (OSTI)

Energy conservation strategies and production economies involve more than examining the cooling tower fan consumption of horse power. Colder water provides vast potentials for savings. Ask yourself, "What is the dollar and energy utilization value if I can obtain 1°F colder water off my cooling tower than I am now getting?" Therefore, let us first examine the elements of the cooling tower to determine the areas of greatest potential improvement to generate that colder water. The air flow generated by the fan should first be looked at In both counterflow or crossflow towers to determine that maximum flow is available through pitching fans up to within the motor plate amperage limitations and fan stall point calculations. If applicable, new fiberglass state of the art fans can be installed and additional motor horse power added. However, the most dramatic improvement that can be obtained in producing colder water is to retrofit modern film fill to replace the old fashioned wood splash bar slats.

Technologies that enable wind turbines to capture more energy at a given site have the potential to reduce the overall cost of energy, thereby making wind power more competitive against conventional power generation. Because wind speed generally increases with height above ground, one way to increase energy capture is to elevate the rotor by means of a taller tower. To exploit this potential, a number of tall tower models are under development or have recently been introduced to the wind energy market. I...

Tower Design Load Verification on a 1-kW Wind Turbine: Preprint  

DOE Green Energy (OSTI)

Wind turbine testing at the National Wind Technology Center (NWTC) has been done to characterize both tower top loads and thrust loads for small wind turbines, which is part of an ongoing effort to model and predict small wind turbine behavior and the resulting stresses imposed on the supporting tower. To these ends, a 1-kW furling wind turbine mounted on a 10-meter tower was instrumented and monitored via a data acquisition system for nearly a year. This test was conducted to verify the design loads as predicted by the simple design equations provided in the draft revision of the International Electrotechnical Commission (IEC) Small Wind Turbine Safety Standard 61400-02 CDV (hereafter called ''the draft Standard''). Data were captured for several operating conditions covered by the draft Standard. This paper addresses the collected data and what conclusions can be made from it.

Analysis of 2011 Meteorological Data from the Knolls Atomic Power Laboratory and Kesselring Site Operations Facilities  

SciTech Connect

Both the Knolls Atomic Power Laboratory (KAPL) in Schenectady, NY and the Kesselring Site Operations (KSO) facility near Ballston Spa, NY are required to estimate the effects of hypothetical emissions of radiological material from their respective facilities by the US Environmental Protection Agency (EPA), which regulates these facilities. An atmospheric dispersion model known as CAP88, which was developed and approved by the EPA for such purposes, is used by KAPL and KSO to meet this requirement. CAP88 calculations over a given time period are based on statistical data on the meteorological conditions for that period. Both KAPL and KSO have on-site meteorological towers which take atmospheric measurements at a frequency ideal for EPA regulatory model input. However, an independent analysis and processing of the meteorological data from each tower is required to derive a data set appropriate for use in the CAP88 model. The National Atmospheric Release Advisory Center (NARAC) was contracted by KAPL to process the on-site data for the calendar year 2011. The purpose of this document is to: (1) summarize the procedures used in the preparation/analysis of the 2011 meteorological data; and (2) document adherence of these procedures to the guidance set forth in 'Meteorological Monitoring Guidance for Regulatory Modeling Applications', EPA document - EPA-454/R-99-005 (EPA-454). This document outlines the steps in analyzing and processing meteorological data from the Knolls Atomic Power Laboratory and Kesselring Site Operations facilities into a format that is compatible with the steady state dispersion model CAP88. This process is based on guidance from the EPA regarding the preparation of meteorological data for use in regulatory dispersion models. The analysis steps outlined in this document can be easily adapted to process data sets covering time period other than one year. The procedures will need to be modified should the guidance in EPA-454 be updated or revised.

Wet cooling towers: rule-of-thumb design and simulation  

DOE Green Energy (OSTI)

A survey of wet cooling tower literature was performed to develop a simplified method of cooling tower design and simulation for use in power plant cycle optimization. The theory of heat exchange in wet cooling towers is briefly summarized. The Merkel equation (the fundamental equation of heat transfer in wet cooling towers) is presented and discussed. The cooling tower fill constant (Ka) is defined and values derived. A rule-of-thumb method for the optimized design of cooling towers is presented. The rule-of-thumb design method provides information useful in power plant cycle optimization, including tower dimensions, water consumption rate, exit air temperature, power requirements and construction cost. In addition, a method for simulation of cooling tower performance at various operating conditions is presented. This information is also useful in power plant cycle evaluation. Using the information presented, it will be possible to incorporate wet cooling tower design and simulation into a procedure to evaluate and optimize power plant cycles.

FLUX MEASUREMENTS FROM A TALL TOWER IN A COMPLEX LANDSCAPE  

Science Conference Proceedings (OSTI)

The accuracy and representativeness of flux measurements from a tall tower in a complex landscape was assessed by examining the vertical and sector variability of the ratio of wind speed to momentum flux and the ratio of vertical advective to eddy flux of heat. The 30-60 m ratios were consistent with theoretical predictions which indicate well mixed flux footprints. Some variation with sector was observed that were consistent with upstream roughness. Vertical advection was negligible compared with vertical flux except for a few sectors at night. This implies minor influence from internal boundary layers. Flux accuracy is a function of sector and stability but 30-60 m fluxes were found to be generally representative of the surrounding landscape. This paper will study flux data from a 300 m tower, with 4 levels of instruments, in a complex landscape. The surrounding landscape will be characterized in terms of the variation in the ratio of mean wind speed to momentum flux as a function of height and wind direction. The importance of local advection will be assessed by comparing vertical advection with eddy fluxes for momentum and heat.

Cooling Towers, The Neglected Energy Resource

Loving care is paid to the compressors, condensers, and computer programs of refrigeration and air conditioning systems. When problems arise, operators and engineers run around in circles with expensive "fixes" , but historically ignore the poor orphan of the system, the cooling tower perched on the roof or located somewhere in the backyard. When cooling water is too hot, high temperature cut-outs occur and more energy must be provided to the motors to maintain the refrigeration cycle. Cooling towers: 1) are just as important a link in the chain as the other equipment; 2) are an important source of energy conservation; 3) can be big money makers; 4) operators should be aware of the potential of maximising cold water. Most towers were designed over 20 years ago and were inefficiently engineered due to cheap power and the "low bidder gets the sale" syndrome. Operating energy costs were ignored and purchasing criteria was to award the contract to the lowest bidder. All too often the low bidder - even though some of the most respected firms were involved - cut thermal corners for the sale. This paper investigates the internal elements of the typical types of cooling towers currently used, delineates their functions and shows how to upgrade them in the real world for energy savings and profitability of operation. Hard before and after statistics of costs and profits obtained through optimization of colder water by engineered thermal upgrading will be discussed. Salient points will be reenforced with on-the-job, hands-on, slides and illustrations.

Untapped Energy Savings from Cooling Towers  

E-Print Network (OSTI)

A cooling tower is often an overlooked source of easy energy savings. As long as it's running not much thought is usually given to it, but when numbers are applied to how much a degree of colder water is worth it can become a valuable and ready source of energy and monetary savings. Many of these savings can come from simple maintenance or by changing the way the tower is operated. The more dramatic savings can come from changing to advanced fill concepts. Over our 40 years of working in the cooling tower industry we have measured the effects of doing simple maintenance, the effects of blocking air flow with seemingly good ideas like maintenance walkways, the effects of nearby heat sources, and what fill changes are likely to get. We have put numbers to what a degree is worth to a large petrochemical company so you can get an idea of the magnitude of what these sometimes simple changes are actually worth. Also, we've included a way to monitor your tower for changes in performance.

PERFORMANCE ANALYSIS OF MECHANICAL DRAFT COOLING TOWER  

SciTech Connect

Industrial processes use mechanical draft cooling towers (MDCT's) to dissipate waste heat by transferring heat from water to air via evaporative cooling, which causes air humidification. The Savannah River Site (SRS) has cross-flow and counter-current MDCT's consisting of four independent compartments called cells. Each cell has its own fan to help maximize heat transfer between ambient air and circulated water. The primary objective of the work is to simulate the cooling tower performance for the counter-current cooling tower and to conduct a parametric study under different fan speeds and ambient air conditions. The Savannah River National Laboratory (SRNL) developed a computational fluid dynamics (CFD) model and performed the benchmarking analysis against the integral measurement results to accomplish the objective. The model uses three-dimensional steady-state momentum, continuity equations, air-vapor species balance equation, and two-equation turbulence as the basic governing equations. It was assumed that vapor phase is always transported by the continuous air phase with no slip velocity. In this case, water droplet component was considered as discrete phase for the interfacial heat and mass transfer via Lagrangian approach. Thus, the air-vapor mixture model with discrete water droplet phase is used for the analysis. A series of parametric calculations was performed to investigate the impact of wind speeds and ambient conditions on the thermal performance of the cooling tower when fans were operating and when they were turned off. The model was also benchmarked against the literature data and the SRS integral test results for key parameters such as air temperature and humidity at the tower exit and water temperature for given ambient conditions. Detailed results will be published here.

Concentrating Solar Power Tower System Basics Concentrating Solar Power Tower System Basics Concentrating Solar Power Tower System Basics August 20, 2013 - 5:06pm Addthis In power tower concentrating solar power systems, numerous large, flat, sun-tracking mirrors, known as heliostats, focus sunlight onto a receiver at the top of a tall tower. A heat-transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. Some power towers use water/steam as the heat-transfer fluid. Other advanced designs are experimenting with molten nitrate salt because of its superior heat-transfer and energy-storage capabilities. Individual commercial plants can be sized to produce up to 200 megawatts of electricity. Illustration of a power tower power plant. Sunlight is shown reflecting off a series of heliostats surrounding the tower and onto the receiver at the top of the tower. The hot heat-transfer fluid exiting from the receiver flows down the tower, into a feedwater reheater, and then into a turbine, which generates electricity that is fed into the power grid. The cool heat-transfer fluid exiting the turbine flows into a steam condenser to be cooled and sent back up the tower to the receiver.

Predict particle collection in spray towers  

SciTech Connect

Spray tower wet scrubbers are used for control of particulates (as well as gaseous pollutants). The author has found that in cocurrent spray scrubbers, the most important parameter in determining particle collection efficiency is inlet dust particle size, followed by (in decreasing order of importance) gas velocity, collector droplet size, liquid-to-gas ratio, and length of scrubber. In countercurrent scrubbers, the most important parameters are collector droplet size, liquid-to-gas ratio, length of scrubber, and gas velocity. Note that some of these factors are directly related to collection, and some are related indirectly. This article provides equations, based on theoretical considerations and empirical data, for predicting particle collection efficiencies. The parameter ranges covered are typical of those encountered in the practical operation of conventional spray towers that use a ``cool`` (or cooled) inlet gas stream, so the equations are applicable to many industrial spray tower systems. The results are limited based on the ranges of the parameters evaluated, and while it may be possible to extrapolate beyond that, this has not been verified. (The initial model was for a flue-gas desulfurization system at a large power station that requires both particulate removal and SO{sub 2} absorption.)

The energy use characteristics of evaporative cooling towers are of interest because, although such towers are widely used in industry, they do require a substantial amount of energy. Evaporative cooling towers are basically large heat exchangers that use both sensible heat transfer and mass transfer to cool. The heat and mass transfer process for a crossflow cooling tower has been modeled on an Apple II microcomputer. Various heat loads or weather conditions can be imposed on a given tower to evaluate its response; moreover, a subprogram can evaluate pressure drop and motor/fan characteristics. Determination of the energy required to operate the tower enables its performance to be compared against energy-saving operations such as variable speed drive or changes in fill height or type.

Vortex-augmented cooling tower-windmill combination  

DOE Patents (OSTI)

A cooling tower for cooling large quantities of effluent water from a production facility by utilizing natural wind forces includes the use of a series of helically directed air inlet passages extending outwardly from the base of the tower to introduce air from any direction in a swirling vortical pattern while the force of the draft created in the tower makes it possible to place conventional power generating windmills in the air passages to provide power as a by-product.

Candidate wind-turbine-generator site summarized meteorological data for December 1976-December 1981. [Program WIND listed  

DOE Green Energy (OSTI)

Summarized hourly meteorological data for 16 of the original 17 candidate and wind turbine generator sites collected during the period from December 1976 through December 1981 are presented. The data collection program at some individual sites may not span this entire period, but will be contained within the reporting period. The purpose of providing the summarized data is to document the data collection program and provide data that could be considered representative of long-term meteorological conditions at each site. For each site, data are given in eight tables and a topographic map showing the location of the meteorological tower and turbine, if applicable. Use of information from these tables, along with information about specific wind turbines, should allow the user to estimate the potential for long-term average wind energy production at each site.

Application of upspray type water distribution systems in cooling towers  

SciTech Connect

The efficient and uniform distribution of the warm circulating water on to the filling of cooling towers has been the continuing goal of the tower designer. The final element in the water distribution system, the sprayer, plays an important role in achieving this objective. This paper discusses the performance and operational characteristics of a sprayer utilized in counterflow towers that directs the water leaving the sprayer nozzle in an upward direction and briefly compares its performance with that of downward sprayers. The discussion also covers relative tower economics and application data of the sprayer.

Hydraulic Cooling Tower Driver- The Innovation  

E-Print Network (OSTI)

One of the weaknesses of present day cooling tower drives are fan wrecks caused by shaft couplings breaking, gear box malfunctions due to inadequate lubrication, gear tooth wear, and inaccessibility for inspection and routine maintenance. The hydro-drive eliminates these items from the drive train and puts the same electric motor HP at ground level close coupled to a hydraulic pump, filters, and oil reservoir. Hydraulic lines bring oil pressure to the hydraulic motor, which is more than 75% less weight than comparable gear boxes and presents a smooth practically trouble free performance. In this three cell installation, the original 75 horsepower motors and 18’ diameter fans were cooling a total of 14,000 GPM which were CTI tested and 74.7% of capability. The upgrading and retrofit consisted of installing at ground level 100 horse power motors, 22’ diameter fans, 14’ high velocity recovery fan cylinders, “V” PVC splash bars, and high efficiency cellular drift eliminators. Testing after completion indicated a 92% tower now circulating 21,000 GPM instead of the original 14,000.

A virtual tall tower network for understanding continental sources and sinks of CO2  

SciTech Connect

Our understanding of the North American terrestrial carbon cycle is limited by both a lack of continental atmospheric CO2 data, and by a need for methods to interpret these and other continental data with confidence. In response to this challenge a rapid expansion of the N. American carbon cycle observational network is underway. This expansion includes a network of continuous, continental CO2 mixing ratio observations being collected at a subset of AmeriFlux towers. Progress in developing this resource includes instrument development, site installation, calibration and intercalibration efforts, and initiation of a uniform data product. Progess in applying these data include proposed methods for interpreting surface layer measurements in atmospheric inversions (the virtual tall towers approach), examination of coherence patterns in continental mixing ratios in response to weather and climate, and application of these mixing ratio measurements in formal atmospheric inversions. Future work will merge these methods with interpretation of flux towers observations of terrestrial carbon fluxes in an effort to create a single coherent diagnosis of North American terrestrial carbon fluxes over a multi-year period.

Hydrogen Storage in Wind Turbine Towers: Design Considerations; Preprint  

DOE Green Energy (OSTI)

The paramount considerations associated with a hydrogen tower are corrosion (in the form of hydrogen embrittlement) and structural failure (through bursting or fatigue life degradation). Although hydrogen embrittlement (HE) requires more research and experimentation, it does not appear to prohibit the use of turbine towers for hydrogen storage. Furthermore, the structural modifications required to store hydrogen in a tower are technically feasible. We discovered that hydrogen towers have a''crossover pressure'' at which their critical mode of failure crosses over from fatigue to bursting. The crossover pressure for many turbine towers is between 10 and 15 atm. The cost of hydrogen storage per unit of storage capacity is lowest near the crossover pressure. Above the crossover pressure, however, storage costs rise quickly.

Power Tower Technology Roadmap and cost reduction plan.  

DOE Green Energy (OSTI)

Concentrating solar power (CSP) technologies continue to mature and are being deployed worldwide. Power towers will likely play an essential role in the future development of CSP due to their potential to provide dispatchable solar electricity at a low cost. This Power Tower Technology Roadmap has been developed by the U.S. Department of Energy (DOE) to describe the current technology, the improvement opportunities that exist for the technology, and the specific activities needed to reach the DOE programmatic target of providing competitively-priced electricity in the intermediate and baseload power markets by 2020. As a first step in developing this roadmap, a Power Tower Roadmap Workshop that included the tower industry, national laboratories, and DOE was held in March 2010. A number of technology improvement opportunities (TIOs) were identified at this workshop and separated into four categories associated with power tower subsystems: solar collector field, solar receiver, thermal energy storage, and power block/balance of plant. In this roadmap, the TIOs associated with power tower technologies are identified along with their respective impacts on the cost of delivered electricity. In addition, development timelines and estimated budgets to achieve cost reduction goals are presented. The roadmap does not present a single path for achieving these goals, but rather provides a process for evaluating a set of options from which DOE and industry can select to accelerate power tower R&D, cost reductions, and commercial deployment.

Experimental Investigation of the Padding Tower for Air Dehumidifier  

E-Print Network (OSTI)

Air conditioning with all fresh air is founded on the principle of dehumidifying by liquid desiccant. It has the characteristics of being clean, power-saving, easy to operate, and requiring low-grade heat. It is suitable for applying waste heat, and solar power as the heat source for regeneration. Hence, this system has a great latent potential for energy savings and environmental protection. The system chooses the padding tower as a dehumidifier and regenerator, which are often used in petrochemical industry. The system chooses a padding tower as a dehumidifier, and LiCl-Water as a liquid desiccant. The vapor in the air is absorbed by the spray of the LiCl solution, and then the absorbed vapor will be released by heating the absorbent. These processes form the circle of absorptive refrigeration operating in atmospheric pressure. This paper describes studies on the theory and experiment of the padding tower of the dehumidifying air conditioning, including selecting different padding and measuring the speed of the air flow and the solution flow and the pressure drop between the layers of the padding. The experimental and computational results indicate that the design parameters of the padding tower significantly influence the characteristics of the liquid desiccant air conditioning. Of these design parameters, the framework of the padding tower, ratio of the air and the concentration of the inlet solution is largest through the tower, the temperature and effects of the dehumidifying capability of the tower.

Use of nanofiltration to reduce cooling tower water consumption.  

Science Conference Proceedings (OSTI)

Nanofiltration (NF) can effectively treat cooling-tower water to reduce water consumption and maximize water usage efficiency of thermoelectric power plants. A pilot is being run to verify theoretical calculations. A side stream of water from a 900 gpm cooling tower is being treated by NF with the permeate returning to the cooling tower and the concentrate being discharged. The membrane efficiency is as high as over 50%. Salt rejection ranges from 77-97% with higher rejection for divalent ions. The pilot has demonstrated a reduction of makeup water of almost 20% and a reduction of discharge of over 50%.

The Tower Shielding Facility: Its glorious past  

Science Conference Proceedings (OSTI)

The Tower Shielding Facility (TSF) is the only reactor facility in the US that was designed and built for radiation-shielding studies in which both the reactor source and shield samples could be raised into the air to allow measurements to be made without interference from ground scattering or other spurious effects. The TSF proved its usefulness as many different programs were successfully completed. It became active in work for the Defense Atomic Support Agency (DASA) Space Nuclear Auxiliary Power, Defense Nuclear Agency, Liquid Metal Fast Breeder Reactor Program, the Gas-Cooled and High-Temperature Gas-Cooled Reactor programs, and the Japanese-American Shielding Program of Experimental Research, just to mention a few of the more extensive ones. The history of the TSF as presented in this report describes the various experiments that were performed using the different reactors. The experiments are categorized as to the programs which they supported and placed in corresponding chapters. The experiments are described in modest detail, along with their purpose when appropriate. Discussion of the results is minimal, but references are given to more extensive topical reports.

Introducing an Online Cooling Tower Performance Analysis Tool  

E-Print Network (OSTI)

Cooling towers are used extensively for numerous industrial, residential, and commercial applications. Yet despite how common their uses, operators often do not know how to properly evaluate and optimize their performance. This is due to the complex and variable nature of all of the factors that can influence performance; fan speed, wind speed, sump temperature, heat load, ambient temperature, relative humidity, etc. This can be overwhelming for a regular operator resulting in many cooling towers being set to a default operating condition and forgotten. This paper will introduce a web-based cooling tower analysis tool being developed to help users understand and optimize operational efficiency. The calculations, evaluations, and models will be discussed in detail to highlight important design considerations and issues. This will include how the Merkel Theory, psychometric properties, tower types, and historical weather data are incorporated into the analysis.

Environmental Impacts from the Operation of Cooling Towers at SRP  

SciTech Connect

An assessment has been made of the environmental effects that would occur from the operation of cooling towers at the SRP reactors. A more realistic numerical model of the cooling tower plume has been used to reassess the environmental impacts. The following effects were considered: (1) the occurrence of fog and ice and their impact on nearby structures, (2) drift and salt deposition from the plume, (3) the length and height of the visible plume, and (4) the possible dose from tritium.

Cooling-tower rebuild, treatment overhaul halt fouling  

SciTech Connect

Partial fixes over a period of time were insufficient to meet cooling requirements at this four-tower powerplant. The eventual remedy involved complete fill replacement and chemistry-program revision. Cooling-tower performance hinges on many factors. Assuming the proper water and air distribution and unhindered operation of spray nozzles, pumps, valves, etc, fill design is the key element. However, a decade of experience at Keystone station (operated by Pennsylvania Electric Co for a consortium of East Coast utilities) showed that more than just changing to a fouling-resistant fill was required to provide and maintain design performance. As described in this article, careful analysis, revision, and continuous monitoring of the chemical water-treatment program were needed as well. At each of Keystone's two units, two natural-draft, hyperbolic towers provide cooling for main-condenser circulating water and service water. The 325-ft-tall towers are counter-current flow, and measure 247 ft across the basin. Film-type fill originally installed in the towers consisted of assemblies of fiber-cement board, 9 ft deep in the center and 7 ft in the peripheral regions. Fiber-cement was also the construction material used in the drift eliminators, and in the piping connected to concrete distribution flumes within the towers.

Wind Shear Characteristics at Central Plains Tall Towers  

Science Conference Proceedings (OSTI)

The object of this study is to analyze wind shear characteristics at tall tower sites in the Central Plains of the United States. The hub heights of modern turbines used for wind farm projects are now 70 meters (m) to 100 m above ground and some advanced turbines under development for deployment during the second half of this decade are rated at 2-5 megawatts of energy generation with rotor diameters near 100 m and hub heights of 100-120 m. These advanced turbines will take advantage of the higher wind speeds aloft to generate more wind energy. Specific knowledge of important wind shear characteristics near and at turbine hub height is needed to optimize turbine design and wind farm layout. Unfortunately, wind speed shear measurements at heights of 80-120 m were virtually nonexistent a few years ago and are still quite uncommon today. The Central Plains is a prime wind energy development region and knowledge about the wind shear characteristics will reduce uncertainty about the resource and enhance wind farm design. Previous analyses of tall tower data (Schwartz and Elliott, 2005) concentrated on data from specific states. The wind energy community has recognized the need to fill the gap of direct wind speed measurements at levels 70 m and higher above the ground. Programs instituted during the last 5 years at the state level and supported by the U.S. Department of Energy's (DOE) State Energy Program initiative have placed anemometers and vanes at several levels on existing tall (70 m+) communication towers. The Central Plains has a fairly high concentration of tall tower sites. The distribution of tall tower sites varies among the states in the Central Plains, because the tall tower program is new and the available state and federal funding to establish tall towers is variable. Our wind resource assessment group at DOE's National Renewable Energy Laboratory (NREL) has obtained much of these necessary measurement data from both individual state sources and regional organizations. Most of the data are available to the public, though data from one tower in Colorado are proprietary. We have begun to analyze important wind climate parameters, including wind shear from the tall towers. A total of 13 tall towers were used for this study. Eleven of the towers had the highest anemometer level between 100 m and 113 m. Two towers had the highest measurement level between 70 m and 85 m above ground. The distribution of the towers among the states is: two sites in Texas and Oklahoma; six sites in Kansas; and one site each in Colorado, South Dakota, and North Dakota. Figure 1 shows the locations and names of the thirteen towers. The wind resource at these sites can be classified as ranging from good-to-excellent. Eight tall tower sites have Class 3 resource, four sites have Class 4 resource, and one has Class 5 resource at 50 m.

Instrumented SSH  

Science Conference Proceedings (OSTI)

NERSC recently undertook a project to access and analyze Secure Shell (SSH) related data. This includes authentication data such as user names and key fingerprints, interactive session data such as keystrokes and responses, and information about noninteractive sessions such as commands executed and files transferred. Historically, this data has been inaccessible with traditional network monitoring techniques, but with a modification to the SSH daemon, this data can be passed directly to intrusion detection systems for analysis. The instrumented version of SSH is now running on all NERSC production systems.

Analysis of mass transfer performance in an air stripping tower  

Science Conference Proceedings (OSTI)

The carryover of working solution in a traditional stripping tower is of serious concern in real applications. A U-shaped spray tower to prevent carryover has been designed to study the stripping of water vapor from aqueous desiccant solutions of 91.8 to 95.8 wt% triethylene glycol. In this study, water vapor was removed from the diluted desiccant solution by heating the solution and stripping it with the ambient air. Therefore, the solution was concentrated to a desired concentration. This spray tower was capable of handling air flow rates from 3.2 to 5.13 kg/min and liquid flow rates from 1.6 to 2.76 kg/min. Since the literature data on air stripping towers are limited, studies on the mass transfer coefficient and other mass transfer parameters were carried out in this study. Under the operating conditions, the overall mass transfer coefficient calculated from the experimental data varied from 0.053 to 0.169 mol/m{sup 3}{center{underscore}dot}s. These corresponded to heights of a transfer unit of 2.3 to 0.71 m, respectively. The rates of stripping in this spray tower were typically varied from 2.28 to 12.15 kg H{sub 2}O/h. A correlation of the mass transfer coefficient for the air stripping process was also developed in this study.

Integrated reactor-containment hyperbolic-cooling-tower system  

Science Conference Proceedings (OSTI)

A preliminary feasibility analysis has been conducted to evaluate placing a nuclear reactor containment building inside a large hyperbolic cooling tower, a concept previously suggested for fossil-fired units but for reasons other than those that motivate this evaluation. The geometry of the design, the amount of water available, and the shielding provided by the cooling tower are beneficial to the safety characteristics of the containment under accident conditions. Three means of decay heat management are employed: an initial water spray on the containment exterior, long-term air convection on side of the containment, and creation of a water pool inside the containment. A continuously spraying water tank on top of the containment allows for a completely passive decay heat removal system. An annular air chimney around the containment is effective in long-term removal of {approximately} 1O MW (thermal) through air convection. Five percent of the water inventory in the cooling-tower pond surrounding the containment is sufficient to flood the containment interior to a depth of 14.6 ft, thereby providing an internal containment heat sink. The packing and the height of the tower provide major scrubbing and dispersing sources for any uncontrolled radioactive leak. The cooling tower veil also protects the containment from external events such as lane crashes.

Testing of an impedance heating system for solar power tower applications  

DOE Green Energy (OSTI)

A non-conventional type of heating system is being tested at Sandia National Laboratories for solar thermal power tower applications. In this system, called impedance heating, electric current flows directly through the pipe to maintain the desired temperature. The pipe becomes the resistor where the heat is generated. Impedance heating has many advantages over previously used mineral insulated (MI) heat trace. An impedance heating system should be much more reliable than heat trace cable since delicate junctions and cabling are not used and the main component, a transformer, is inherently reliable. A big advantage of impedance heating is the system can be sized to rapidly heat up the piping to provide rapid response times necessary in cyclic power plants such as solar power towers. In this paper, experimental results from testing an impedance heating system are compared to MI cable heat trace. We found impedance heating was able to heat piping rapidly and effectively. There were not significant stray currents and impedance heating did not affect instrumentation.

Cooling Towers - Energy Conservation and Money Making Mechanisms  

E-Print Network (OSTI)

The utilization of colder water conserves energy, creates profits, increases product output. In an effort to obtain greater efficiencies and conserve both energy and dollars, all too many engineers neglect the potential of the cooling tower. Many cooling towers in operation are performing at levels as low as 50% of capability. This is energy wasteful and financially foolish. There are many reasons for this deficiency, among them the present service is greater than the original requirements, slippage due to age and deterioration, or the installation could have been originally installed undersized. This paper will investigate the various elements, their functions and methods of upgrading their performance by retrofit with the use of modern technology. Case histories will be examined in three major industries, chemicals, refrigeration and petrochemical illustrating how intelligent rebuilding can produce profits and conserve energy. Actual statistics will be cited showing that the return of investment (ROI) can be quite rapid by optimizing the performance of the cooling tower.

Conversion of Solar Two to a Kokhala hybrid power tower  

DOE Green Energy (OSTI)

The continued drop in energy prices and restructuring of the utility industry have reduced the likelihood that a follow-on commercial 100-MW, power tower project will be built immediately following the Solar Two demonstration project. Given this, it would be desirable to find a way to extend the life of the Solar Two project to allow the plant to operate as a showcase for future power tower projects. This paper looks at the possibility of converting Solar Two into a commercial Kokhala hybrid power tower plant at the end of its demonstration period in 1998. The study identifies two gas turbines that could be integrated into a Kokhala cycle at Solar Two and evaluates the design, expected performance, and economics of each of the systems. The study shows that a commercial Kokhala project at Solar Two could produce power at a cost of less than 7 e/kWhr.

THE NEW YORK MIDTOWN DISPERSION STUDY (MID-05) METEOROLOGICAL DATA REPORT.  

SciTech Connect

The New York City midtown dispersion program, MID05, examined atmospheric transport in the deep urban canyons near Rockefeller Center. Little is known about air flow and hazardous gas dispersion under such conditions, since previous urban field experiments have focused on small to medium sized cities with much smaller street canyons and examined response over a much larger area. During August, 2005, a series of six gas tracer tests were conducted and sampling was conducted over a 2 km grid. A critical component of understanding gas movement in these studies is detailed wind and meteorological information in the study zone. To support data interpretation and modeling, several meteorological stations were installed at street level and on roof tops in Manhattan. In addition, meteorological data from airports and other weather instrumentation around New York City were collected. This document describes the meteorological component of the project and provides an outline of data file formats for the different instruments. These data provide enough detail to support highly-resolved computational simulations of gas transport in the study zone.

Dry cooling tower operating experience in the LOFT reactor  

SciTech Connect

A dry cooling tower has been uniquely utilized to dissipate heat generated in a small experimental pressurized water nuclear reactor. Operational experience revealed that dry cooling towers can be intermittently operated with minimal wind susceptibility and water hammer occurrences by cooling potential steam sources after a reactor scram, by isolating idle tubes from the external atmosphere, and by operating at relatively high pressures. Operating experience has also revealed that tube freezing can be minimized by incorporating the proper heating and heat loss prevention features.

Modeling, loading, and preliminary design considerations for tall guyed towers  

Science Conference Proceedings (OSTI)

In this paper, the authors first summarize the results of an investigation they carried out on the collapse of a 1900 ft tall guyed tower under ice and wind loads. Based on this investigation, they then proceed to present some structural analysis recommendations relating to loading and modeling concerns. Special emphasis is placed on the importance of ice loading, and on the level of accuracy required in modeling the nonlinear response behavior. Finally, the conclusions drawn from this study are used to formulate preliminary design guidelines. This facilitates a systematic approach for the design of tall guyed towers. 23 refs.

On Why Disks Generate Magnetic Towers and Collimate Jets  

E-Print Network (OSTI)

We show that accretion disks with magnetic fields in them ought to make jets provided that their electrical conductivity prevents slippage and there is an ambient pressure in their surroundings. We study equilibria of highly wound magnetic structures. General Energy theorems demonstrate that they form tall magnetic towers whose height grows with every turn at a velocity related to the circular velocity in the accretion disk. The pinch effect amplifies the magnetic pressures toward the axis of the towers whose stability is briefly considered.

Utility-Scale Power Tower Solar Systems: Performance Acceptance Test Guidelines  

DOE Green Energy (OSTI)

The purpose of these Guidelines is to provide direction for conducting performance acceptance testing for large power tower solar systems that can yield results of a high level of accuracy consistent with good engineering knowledge and practice. The recommendations have been developed under a National Renewable Energy Laboratory (NREL) subcontract and reviewed by stakeholders representing concerned organizations and interests throughout the concentrating solar power (CSP) community. An earlier NREL report provided similar guidelines for parabolic trough systems. These Guidelines recommend certain methods, instrumentation, equipment operating requirements, and calculation methods. When tests are run in accordance with these Guidelines, we expect that the test results will yield a valid indication of the actual performance of the tested equipment. But these are only recommendations--to be carefully considered by the contractual parties involved in the Acceptance Tests--and we expect that modifications may be required to fit the particular characteristics of a specific project.

Meteorological aspects of siting large wind turbines  

DOE Green Energy (OSTI)

This report, which focuses on the meteorological aspects of siting large wind turbines (turbines with a rated output exceeding 100 kW), has four main goals. The first is to outline the elements of a siting strategy that will identify the most favorable wind energy sites in a region and that will provide sufficient wind data to make responsible economic evaluations of the site wind resource possible. The second is to critique and summarize siting techniques that were studied in the Department of Energy (DOE) Wind Energy Program. The third goal is to educate utility technical personnel, engineering consultants, and meteorological consultants (who may have not yet undertaken wind energy consulting) on meteorological phenomena relevant to wind turbine siting in order to enhance dialogues between these groups. The fourth goal is to minimize the chances of failure of early siting programs due to insufficient understanding of wind behavior.

Solar Power Tower Design Basis Document, Revision 0  

DOE Green Energy (OSTI)

This report contains the design basis for a generic molten-salt solar power tower. A solar power tower uses a field of tracking mirrors (heliostats) that redirect sunlight on to a centrally located receiver mounted on top a tower, which absorbs the concentrated sunlight. Molten nitrate salt, pumped from a tank at ground level, absorbs the sunlight, heating it up to 565 C. The heated salt flows back to ground level into another tank where it is stored, then pumped through a steam generator to produce steam and make electricity. This report establishes a set of criteria upon which the next generation of solar power towers will be designed. The report contains detailed criteria for each of the major systems: Collector System, Receiver System, Thermal Storage System, Steam Generator System, Master Control System, and Electric Heat Tracing System. The Electric Power Generation System and Balance of Plant discussions are limited to interface requirements. This design basis builds on the extensive experience gained from the Solar Two project and includes potential design innovations that will improve reliability and lower technical risk. This design basis document is a living document and contains several areas that require trade-studies and design analysis to fully complete the design basis. Project- and site-specific conditions and requirements will also resolve open To Be Determined issues.

Candidate wind-turbine generator site cumulative meteorological data summary and data for January 1982 through September 1982  

DOE Green Energy (OSTI)

Summarized cumulative hourly meteorological data for 20 new sites selected in early 1980 as part of the expanded candidate site program are presented. The reporting period is July 1980 through September 1982. The data collection program at some individual sites may not span this entire period, but will be contained within the reporting period. The purpose of providing the summarized data is to document the data collection program and to provide data that could be considered representative of longer-term meteorological conditions at each site. For each site, data are given in eight tables and in a topographic map showing the approximated location of the meteorological tower and turbine, if applicable. Use of the information from these tables, along with information about specific wind turbines, should allow the user to estimate the potential for longer-term average wind energy production at each site. Two appendices of other data are provided. Appendix A contains summarized data collected at new and original sites during the period January 1982 through September 1982. Appendix B contains cumulative summarized data for those original sites selected in 1976 with data collection programs continuing into 1982.

Theoretical analysis of natural-convection towers for solar-energy conversion  

DOE Green Energy (OSTI)

A theoretical study of solar-powered natural convection tower (chimney) performance is presented. Both heated and cooled towers are analyzed, the latter using evaporating water as the cooling mechanism. The results, which are applicable to any open-cycle configuration, show that the ideal conversion efficiencies of both heated and cooled natural convection towers are linear functions of height. The performance of a heated tower in an adiabatic atmospheric ideally approaches the Carnot efficiency limit of approx. 3.4%/km(1.0%/1000 ft). Including water pumping requirements, the ideal limit to cooled tower performance is approx. 2.75%/km(0.85%/1000 ft). Ambient atmospheric conditions such as vertical temperature gradient (lapse rate) and relative humidity can have significantly adverse effects on natural convection tower performance. The combined effects of lapse rate and ambient relative humidity are especially important for cooled natural convection towers.

Computer Simulation of Cooling Effect of Wind Tower on Passively Ventilated Building  

E-Print Network (OSTI)

Traditional buildings are cooled and ventilated by mechanically induced drafts. Natural ventilation aspires to cool and ventilate a building by natural means, such as cross ventilation or wind towers, without mechanical equipment. A simple computer program was developed to simulate airflow through a wind tower based on tower dimensions and air temperature. The program was compared to experimental results with reasonable agreement. Parametric analysis indicates that interior air temperature approaches outdoor air temperature asymptotically as tower height and cross-sectional area are increased, and that it may be more cost effective to increase the tower?s height than its cross sectional area. The program was then used to simulate hour-by-hour indoor air temperatures of an occupied auditorium in Dayton, OH. The results indicate that a large wind tower was able to keep the temperature of an occupied auditorium at a comfortable level year round.

Hanford Meteorological Station computer codes: Volume 8, The REVIEW computer code  

SciTech Connect

The Hanford Meteorological Station (HMS) routinely collects meteorological data from sources on and off the Hanford Site. The data are averaged over both 15 minutes and 1 hour and are maintained in separate databases on the Digital Equipment Corporation (DEC) VAX 11/750 at the HMS. The databases are transferred to the Emergency Management System (EMS) DEC VAX 11/750 computer. The EMS is part of the Unified Dose Assessment Center, which is located on on the ground-level floor of the Federal building in Richland and operated by Pacific Northwest Laboratory. The computer program REVIEW is used to display meteorological data in graphical and alphanumeric form from either the 15-minute or hourly database. The code is available on the HMS and EMS computer. The REVIEW program helps maintain a high level of quality assurance on the instruments that collect the data and provides a convenient mechanism for analyzing meteorological data on a routine basis and during emergency response situations.

No Chemical, Zero Bleed Cooling Tower Water Treatment Process  

E-Print Network (OSTI)

This paper describes a process to treat cooling tower water by means of a fully automated and chemical free mechanical water treatment process. This is an alternative to conventional chemical treatment. Beginning with a suction pump to draw water out of the tower sump, water goes through a permanent magnetic descaler to increase the water solubility and begin the scale inhibition process. This also descales existing scale build-up in the system. Ozone is manufactured from ambient air and injected into the bypass system through a venturi type injector. This kills algae, slime and bacteria and enhances the magnetic descaling process. The final stage filter separates solids from the water to prevent corrosion from impingement. These solids are automatically purged to the sanitary drain. Clarified water is returned to the sump where the process repeats on a 10%-20% by volume side stream basis.

CFD MODELING ANALYSIS OF MECHANICAL DRAFT COOLING TOWER  

Science Conference Proceedings (OSTI)

Industrial processes use mechanical draft cooling towers (MDCT's) to dissipate waste heat by transferring heat from water to air via evaporative cooling, which causes air humidification. The Savannah River Site (SRS) has a MDCT consisting of four independent compartments called cells. Each cell has its own fan to help maximize heat transfer between ambient air and circulated water. The primary objective of the work is to conduct a parametric study for cooling tower performance under different fan speeds and ambient air conditions. The Savannah River National Laboratory (SRNL) developed a computational fluid dynamics (CFD) model to achieve the objective. The model uses three-dimensional steady-state momentum, continuity equations, air-vapor species balance equation, and two-equation turbulence as the basic governing equations. It was assumed that vapor phase is always transported by the continuous air phase with no slip velocity. In this case, water droplet component was considered as discrete phase for the interfacial heat and mass transfer via Lagrangian approach. Thus, the air-vapor mixture model with discrete water droplet phase is used for the analysis. A series of the modeling calculations was performed to investigate the impact of ambient and operating conditions on the thermal performance of the cooling tower when fans were operating and when they were turned off. The model was benchmarked against the literature data and the SRS test results for key parameters such as air temperature and humidity at the tower exit and water temperature for given ambient conditions. Detailed results will be presented here.

High Flux Isotopes Reactor (HFIR) Cooling Towers Demolition Waste Management  

SciTech Connect

This paper describes the results of a joint initiative between Oak Ridge National Laboratory, operated by UT-Battelle, and Bechtel Jacobs Company, LLC (BJC) to characterize, package, transport, treat, and dispose of demolition waste from the High Flux Isotope Reactor (HFIR), Cooling Tower. The demolition and removal of waste from the site was the first critical step in the planned HFIR beryllium reflector replacement outage scheduled. The outage was scheduled to last a maximum of six months. Demolition and removal of the waste was critical because a new tower was to be constructed over the old concrete water basin. A detailed sampling and analysis plan was developed to characterize the hazardous and radiological constituents of the components of the Cooling Tower. Analyses were performed for Resource Conservation and Recovery Act (RCRA) heavy metals and semi-volatile constituents as defined by 40 CFR 261 and radiological parameters including gross alpha, gross beta, gross gamma, alpha-emitting isotopes and beta-emitting isotopes. Analysis of metals and semi-volatile constituents indicated no exceedances of regulatory limits. Analysis of radionuclides identified uranium and thorium and associated daughters. In addition 60Co, 99Tc, 226Rm, and 228Rm were identified. Most of the tower materials were determined to be low level radioactive waste. A small quantity was determined not to be radioactive, or could be decontaminated. The tower was dismantled October 2000 to January 2001 using a detailed step-by-step process to aid waste segregation and container loading. The volume of waste as packaged for treatment was approximately 1982 cubic meters (70,000 cubic feet). This volume was comprised of plastic ({approx}47%), wood ({approx}38%) and asbestos transite ({approx}14%). The remaining {approx}1% consisted of the fire protection piping (contaminated with lead-based paint) and incidental metal from conduit, nails and braces/supports, and sludge from the basin. The waste, except for the asbestos, was volume reduced via a private contract mechanism established by BJC. After volume reduction, the waste was packaged for rail shipment. This large waste management project successfully met cost and schedule goals.

A new microtelesensor chip for meteorology  

SciTech Connect

A new technology exploiting commercial, micro-sensors developed for atomic force microscopy offers breakthrough capability in high accuracy wireless sensors for meteorological measurements. Historically sensors used in air-borne and buoy-based platforms required compromises in performance to achieve the low-weight and low power requirements of the mobile platforms. Recent innovations in microelectromechanical systems (MEMS) provided opportunities to reduce size, weight, and power requirements but each sensor required a specially fabricated device with inherent calibration, repeatability, and traceability problems. This new approach allows identical sensors to be fabricated on the same semiconductor substrate as the conditioning electronics and the telemetry components. Exploiting semiconductor fabrication technology offers the potential to reduce fabrication costs to a few dollars per component. Sensing humidity, temperature and pressure have been demonstrated with plans for meteorological deployment scheduled for later in 1997. Cost, reliability, size, power consumption, and accuracy are key factors in the deployment of advanced meteorological sensor arrays. ORNL is actively integrating the sensing technologies, electronic processing, and telemetry that build a family of sensors with multiple-input capabilities. One of the key elements in ORNL`s sensor technology is coated microcantilever arrays, which form a powerful universal platform for multiple physical and chemical measurements. Telemetry is also being developed to add robust spread-spectrum data transmission capabilities to the necessary signal processing electronics. In collaboration with the NOAA Atmospheric Turbulence and Diffusion Lab, a chip-level temperature/humidity module with onboard telemetry is slated for demonstration later in 1997. Future additions would include sensors for atmospheric pressure, wind velocity, turbulence measurement, and radiometry.

A Regenerative High-Rise Tower in Shreveport, Louisiana  

E-Print Network (OSTI)

Zero Net Energy Buildings are increasingly being designed and constructed in response to the demand for sustainable buildings. But, we must now go beyond merely sustaining our environment for future generations we must provide regenerative designs that restore our natural environment. This paper will document the design of a regenerative high-rise tower in Shreveport, Louisiana, which will serve as a facility to train individuals in a non-profit organization’s renewal strategies and demonstrate by example the pedagogy of regenerative design. The 16-story structure — built in the 1950s and named the Petroleum Tower, reflecting the commodity that then ruled the local economy — was vacant and asbestos-laden when given to the non-profit Community Renewal International (CRI) in 2001. In 2006, funded by a grant from the U.S. Environmental Protection Agency, workers removed the asbestos. Through a follow up grant from the U.S. Department of Energy to support the design process of a new CRI headquarters building, the University of Texas at Austin School of Architecture completed architectural design studies for the building renewal. The principles of this new design include: day lighting, envelope configuration, building integrated photovoltaic systems, green surfaces, ventilation strategies, advanced mechanical cooling systems, regenerative elevator systems, energy management systems, water harvesting, grey water systems, trigeneration systems and a combined heating, hot water and power biodiesel plant.

ON THE STRUCTURE AND STABILITY OF MAGNETIC TOWER JETS  

SciTech Connect

Modern theoretical models of astrophysical jets combine accretion, rotation, and magnetic fields to launch and collimate supersonic flows from a central source. Near the source, magnetic field strengths must be large enough to collimate the jet requiring that the Poynting flux exceeds the kinetic energy flux. The extent to which the Poynting flux dominates kinetic energy flux at large distances from the engine distinguishes two classes of models. In magneto-centrifugal launch models, magnetic fields dominate only at scales {approx}< 100 engine radii, after which the jets become hydrodynamically dominated (HD). By contrast, in Poynting flux dominated (PFD) magnetic tower models, the field dominates even out to much larger scales. To compare the large distance propagation differences of these two paradigms, we perform three-dimensional ideal magnetohydrodynamic adaptive mesh refinement simulations of both HD and PFD stellar jets formed via the same energy flux. We also compare how thermal energy losses and rotation of the jet base affects the stability in these jets. For the conditions described, we show that PFD and HD exhibit observationally distinguishable features: PFD jets are lighter, slower, and less stable than HD jets. Unlike HD jets, PFD jets develop current-driven instabilities that are exacerbated as cooling and rotation increase, resulting in jets that are clumpier than those in the HD limit. Our PFD jet simulations also resemble the magnetic towers that have been recently created in laboratory astrophysical jet experiments.

Coagulation chemistries for silica removal from cooling tower water.  

SciTech Connect

The formation of silica scale is a problem for thermoelectric power generating facilities, and this study investigated the potential for removal of silica by means of chemical coagulation from source water before it is subjected to mineral concentration in cooling towers. In Phase I, a screening of many typical as well as novel coagulants was carried out using concentrated cooling tower water, with and without flocculation aids, at concentrations typical for water purification with limited results. In Phase II, it was decided that treatment of source or make up water was more appropriate, and that higher dosing with coagulants delivered promising results. In fact, the less exotic coagulants proved to be more efficacious for reasons not yet fully determined. Some analysis was made of the molecular nature of the precipitated floc, which may aid in process improvements. In Phase III, more detailed study of process conditions for aluminum chloride coagulation was undertaken. Lime-soda water softening and the precipitation of magnesium hydroxide were shown to be too limited in terms of effectiveness, speed, and energy consumption to be considered further for the present application. In Phase IV, sodium aluminate emerged as an effective coagulant for silica, and the most attractive of those tested to date because of its availability, ease of use, and low requirement for additional chemicals. Some process optimization was performed for coagulant concentration and operational pH. It is concluded that silica coagulation with simple aluminum-based agents is effective, simple, and compatible with other industrial processes.

Meteorological analysis for clusters of wind turbines  

DOE Green Energy (OSTI)

A demonstration qualifying the meteorological spectral gap hypothesis is given. It is shown that the peak in the micrometeorological frequency range is at an anomalous level according to a demonstration made using a state-of-the-art micrometeorological spectrum. A spectral model for calculation of rms values for the unstable atmosphere is presented. It is found that theoretically the rms of the unstable atmosphere is about 1.7 times that of the neutral atmosphere when the frequency band considered is one cycle per 30 minutes to one cycle per minute. A spectral model for spatial correlation in neutral conditions is suggested. It is based on Fourier transformation of the above-mentioned spectrum.

E-Print Network (OSTI)

Abstract. Solar diffuse radiation data including global radiation, shortwave and longwave balances, net radiation and sunshine hours have been extensively analyzed to study the variation of diffuse radiation with turbidity and cloud discharges appearing in the form of atmospherics over the tropics. Results of surface radiation measurements at Calcutta, Poona, Delhi and Madras are presented together with some meteorological parameters. The monthly values of diffuse radiation and the monthly ratios of diffuse to global solar radiation have been examined, with a special emphasis in relation to the noise level of atmospherics at Calcutta in the very low frequency band. The results exhibit some definite seasonal changes which appear to be in close agreement with one another. 1

Method and system for simulating heat and mass transfer in cooling towers  

DOE Patents (OSTI)

The present invention is a system and method for simulating the performance of a cooling tower. More precisely, the simulator of the present invention predicts values related to the heat and mass transfer from a liquid (e.g., water) to a gas (e.g., air) when provided with input data related to a cooling tower design. In particular, the simulator accepts input data regarding: (a) cooling tower site environmental characteristics; (b) cooling tower operational characteristics; and (c) geometric characteristics of the packing used to increase the surface area within the cooling tower upon which the heat and mass transfer interactions occur. In providing such performance predictions, the simulator performs computations related to the physics of heat and mass transfer within the packing. Thus, instead of relying solely on trial and error wherein various packing geometries are tested during construction of the cooling tower, the packing geometries for a proposed cooling tower can be simulated for use in selecting a desired packing geometry for the cooling tower.

Abstract (max. 2000 char.): Autonomous Aerial Sensors, i.e. meteorological sensors mounted on Unmanned Aerial Systems UAS, can characterise the atmospheric flow in and around wind farms. We instrumented three planes, a helicopter and a lighter-than-air LTA system to fly one week together in a well-instrumented wind farm, partly with nanosynchronised sensors (time stamped with about 100 ns global accuracy). Between bankruptcy of a partner, denied overflight rights at the main test location, denied Civil Aviation Authorities permits at the alternative location, stolen planes, and crashed UAS we managed to collect data at a wind farm in Lolland and on an atmospheric campaign in France. Planning of an offshore campaign using the developed techniques is underway. ISSN 0106-2840 ISBN 978-87-550-3945-2 Contract no.:

Verification of BModes: Rotary Beam and Tower Modal Analysis Code; Preprint  

DOE Green Energy (OSTI)

This paper describes verification of BModes, a finite-element code developed to provide coupled modes for the blades and tower of a wind turbine. The blades, which may be rotating or non-rotating, and the towers, whether onshore or offshore, are modeled using specialized 15-dof beam finite elements. Both blade and tower models allow a tip attachment, which is assumed to be rigid body with six moments of inertia, and a mass centroid that may be offset from the blade or tower axis. Examples of tip attachments are aerodynamic brakes for blades and nacelle-rotor subassembly for towers. BModes modeling allows for tower supports including tension wires, floating platforms, and monopiles on elastic foundations. Coupled modes (implying coupling of flap, lag, axial, and torsional motions) are required for modeling major flexible components in a modal-based, aeroelastic code such as FAST1. These are also required for validation of turbine models using experimental data, modal-based fatigue analysis, controls design, and understanding aeroelastic-stability behavior of turbines. Verification studies began with uniform tower models, with and without tip inertia, and progressed to realistic towers. For the floating turbine, we accounted for the effects of hydrodynamic inertia, hydrostatic restoring, and mooring lines stiffness. For the monopole-supported tower, we accounted for distributed hydrodynamic mass on the submerged part of the tower and for distributed foundation stiffness. Finally, we verified a model of a blade carrying tip mass and rotating at different speeds (verifications of other blade models, rotating or non-rotating, have been reported in another paper.) Verifications were performed by comparing BModes-generated modes with analytical results, if available, or with MSC.ADAMS results. All results in general show excellent agreement.

Solar two: A molten salt power tower demonstration  

Science Conference Proceedings (OSTI)

A consortium of United States utility concerns led by the Southern California Edison Company (SCE) is conducting a cooperative project with the US Department of Energy (DOE), Sandia National Laboratories, and industry to convert the 10-MW Solar One Power Tower Pilot Plant to molten nitrate salt technology. The conversion involves installation of a new receiver, a new thermal storage system, and a new steam generator; it utilizes Solar One`s heliostat field and turbine generator. Successful operation of the converted plant, called Solar Two, will reduce economic risks in building initial commercial power tow projects and accelerate the commercial acceptance of this promising renewable energy technology. The estimated cost of Solar Two, including its three-year test period, is $48.5 million. The plant will begin operation in early 1996.

Energy (Cost) Savings by Zero Discharge in Cooling Towers  

E-Print Network (OSTI)

Maximum reuse of cooling tower blowdown by the incorporation of a sidestream softening system to recycle water can allow for significant savings in energy costs for industry. The system design parameters described in this paper are based upon calcium sulfate, calcium carbonate, and silica solubility equations for the resultant high ionic strength of a zero blowdown system. Operational aspects are highlighted in terms of deposition, corrosion, and biofouling potentials as well as currently-practiced, successful treatment procedures. The effects and history of corrosion and scale inhibitors, as well as other treatment chemicals, have been evaluated for numerous plants utilizing zero blowdown, and a summation of this knowledge is presented here. The cost analysis of conventional systems versus recycle systems is based upon a computer model's predictions for makeup waters of various qualities and costs.

The evolution of magnetic tower jets in the laboratory  

E-Print Network (OSTI)

The evolution of laboratory produced magnetic jets is followed numerically through three-dimensional, non-ideal magnetohydrodynamic simulations. The experiments are designed to study the interaction of a purely toroidal field with an extended plasma background medium. The system is observed to evolve into a structure consisting of an approximately cylindrical magnetic cavity with an embedded magnetically confined jet on its axis. The supersonic expansion produces a shell of swept-up shocked plasma which surrounds and partially confines the magnetic tower. Currents initially flow along the walls of the cavity and in the jet but the development of current-driven instabilities leads to the disruption of the jet and a re-arrangement of the field and currents. The top of the cavity breaks-up and a well collimated, radiatively cooled, 'clumpy' jet emerges from the system.

Cooling Tower Energy Conservation Through Hydraulic Fan Drives  

E-Print Network (OSTI)

Many companies offer gearboxes, shafts, and couplings for cooling tower fan drives, with little or no innovation. These companies have traditionally been purchased with an emphasis on cost and not "Return on Investment!" In the past, when energy conservation or "Return on Investment" was emphasized, the only alternative was to add an expensive frequency inverter for variable speed control. This meant expensive rewiring, placing additional controls in an already crowded control room, or constructing a special building for them. However, with H.E.M.'s patented Hydraulic Fan Drive, one receives variable speed control and more efficiency for approximately the price of a mechanical drive. The new, more efficient Hydraulic Drive allows for a variable speed control and the ability to sense water temperature to control fan speed.

Flue gas injection control of silica in cooling towers.  

Science Conference Proceedings (OSTI)

Injection of CO{sub 2}-laden flue gas can decrease the potential for silica and calcite scale formation in cooling tower blowdown by lowering solution pH to decrease equilibrium calcite solubility and kinetic rates of silica polymerization. Flue gas injection might best inhibit scale formation in power plant cooling towers that use impaired makeup waters - for example, groundwaters that contain relatively high levels of calcium, alkalinity, and silica. Groundwaters brought to the surface for cooling will degas CO{sub 2} and increase their pH by 1-2 units, possibly precipitating calcite in the process. Recarbonation with flue gas can lower the pHs of these fluids back to roughly their initial pH. Flue gas carbonation probably cannot lower pHs to much below pH 6 because the pHs of impaired waters, once outgassed at the surface, are likely to be relatively alkaline. Silica polymerization to form scale occurs most rapidly at pH {approx} 8.3 at 25 C; polymerization is slower at higher and lower pH. pH 7 fluids containing {approx}220 ppm SiO{sub 2} require > 180 hours equilibration to begin forming scale whereas at pH 8.3 scale formation is complete within 36 hours. Flue gas injection that lowers pHs to {approx} 7 should allow substantially higher concentration factors. Periodic cycling to lower recoveries - hence lower silica concentrations - might be required though. Higher concentration factors enabled by flue gas injection should decrease concentrate volumes and disposal costs by roughly half.

A case history of a coal gasification wastewater cooling tower at the Great Plains coal gasification project  

SciTech Connect

This paper describes the conceptual process design of the Great Plains cooling water system, the fouling history of the cooling tower, and the results of the design modifications. In addition, general design guidelines for future wastewater reuse cooling towers are recommended. By following these guidelines, design engineers can minimize the risk of fouling that could impair a wastewater cooling tower's thermal performance.

Improvement of risk estimate on wind turbine tower buckled by hurricane  

E-Print Network (OSTI)

Wind is one of the important reasonable resources. However, wind turbine towers are sure to be threatened by hurricanes. In this paper, method to estimate the number of wind turbine towers that would be buckled by hurricanes is discussed. Monte Carlo simulations show that our method is much better than the previous one. Since in our method, the probability density function of the buckling probability of a single turbine tower in a single hurricane is obtained accurately but not from one approximated expression. The result in this paper may be useful to the design and maintenance of wind farms.

LIST/BMI Turbines Instrumentation and Infrastructure  

E-Print Network (OSTI)

In support of two major SNL programs, the Long-term Inflow and Structural Test (LIST) program and the Blade Manufacturing Initiative (BMI), three Micon 65/13M wind turbines have been erected at the USDA Agriculture Research Service (ARS) center in Bushland, Texas. The inflow and structural response of these turbines are being monitored with an array of 60 instruments: 34 to characterize the inflow, 19 to characterize structural response and 7 to characterize the time-varying state of the turbine. The primary characterization of the inflow into the LIST turbine relies upon an array of five sonic anemometers. Primary characterization of the structural response of the turbine uses several sets of strain gauges to measure bending loads on the blades and the tower and two accelerometers to measure the motion of the nacelle. Data are sampled at a rate of 30 Hz using a newly developed data acquisition system. The system features a time-synchronized continuous data stream and telemetered data from the turbine rotor. This paper documents the instruments and infrastructure that have been developed to monitor these turbines and their inflow.

Risø–I–1206(EN) Wind Power Meteorology  

E-Print Network (OSTI)

Abstract Wind power meteorology has evolved as an applied science, firmly founded on boundary-layer meteorology, but with strong links to climatology and geography. It concerns itself with three main areas: siting of wind turbines, regional wind resource assessment, and short-term prediction of the wind resource. The history, status and perspectives of wind power meteorology are presented, with emphasis on physical considerations and on its practical application. Following a global view of the wind resource, the elements of boundary layer meteorology which are most important for wind energy are reviewed: wind profiles and shear, turbulence and gust, and extreme winds. The data used in wind power meteorology stem mainly from three sources: onsite wind measurements, the synoptic networks, and the re-analysis projects. Wind climate analysis, wind resource estimation and siting further require a detailed description of the topography of the terrain – with respect to the roughness of the surface, near-by obstacles, and orographical features. Finally, the meteorological models used for estimation and prediction of the wind are described; their classification,

Lab Helps FAA Build Energy-Efficient Control Towers Lab Helps FAA Build Energy-Efficient Control Towers Lab Helps FAA Build Energy-Efficient Control Towers April 23, 2010 - 10:57am Addthis With help from the Pacific Northwest National Laboratory and its subcontractor, Redhorse Corporation, the agency that keeps our country's airports running is bolstering its energy efficiency. The Federal Aviation Administration is developing building plans that save energy - and money - at five airports in the western U.S. Government agencies are required by law to audit their buildings, so the FAA saw some Recovery Act funding as an opportunity to help fund its energy audits. Air traffic control towers are a vital service for travelers, keeping air traffic free of accidents. Their accompanying base buildings house administrative offices and support systems.

BREN Tower: A Monument to the Material Culture of Radiation Dosimetry Research  

Science Conference Proceedings (OSTI)

With a height of more than 1,500 feet, the BREN (Bare Reactor Experiment, Nevada) Tower dominates the surrounding desert landscape of the Nevada Test Site. Associated with the nuclear research and atmospheric testing programs carried out during the 1950s and 1960s, the tower was a vital component in a series of experiments aimed at characterizing radiation fields from nuclear detonations. Research programs conducted at the tower provided the data for the baseline dosimetry studies crucial to determining the radiation dose rates received by the atomic bomb survivors of Hiroshima and Nagasaki, Japan. Today, BREN Tower stands as a monument to early dosimetry research and one of the legacies of the Cold War.

Hydrogen Storage in Wind Turbine Towers: Cost Analysis and Conceptual Design; Preprint  

Science Conference Proceedings (OSTI)

Low-cost hydrogen storage is recognized as a cornerstone of a renewables-hydrogen economy. Modern utility-scale wind turbine towers are typically conical steel structures that, in addition to supporting the rotor, could be used to store hydrogen. The most cost-effective hydrogen tower design would use substantially all of its volume for hydrogen storage and be designed at its crossover pressure. An 84-m tall hydrogen tower for a 1.5-MW turbine would cost an additional $84,000 (beyond the cost of the conventional tower) and would store 950 kg of hydrogen. The resulting incremental storage cost of $88/kg is approximately 30% of that for conventional pressure vessels.

Explosive Demolition of a Fire-Water Tower At East Tennessee Technology Park, Oak Ridge TN  

SciTech Connect

On June 17, 2006, the Department of Energy (DOE) successfully demolished a {approx}60 year old fire-water tower (K-1206-E), located at the East Tennessee Technology Park (ETTP) in Oak Ridge, TN, using strategically placed explosive charges. The subject demolition project was executed by MCM Management Corporation and Demolition Dynamics under the management of DoE's prime contractor Bechtel Jacobs Company LLC (BJC). The K-1206-E Fire Water Tower (Tower) supported the ETTP fire water protection system from the mid- 1950's until 1991. The 378,500-L (100,000-gallon) Tower, elevated 53-m (175-feet) above grade, was located in a grassy area within 152-m (500-feet) of several other occupied facilities. Electrical, control circuits and supply water servicing the Tower were deactivated in 2003. Free liquids and sludge were removed from the tank prior to demolition. Demolition of a facility employing explosive demolition at a federal site in the 'post-9/11 era' was a substantial challenge. The subject paper discusses: - the planning and coordination steps that were taken to successfully overcome the challenges prior to the demolition of the empty, deactivated Tower; - the method used for the engineered demolition of the Tower; and - the factors responsible for the successful execution of this demolition project. At least two previous attempts were made to demolish the Tower. In the first attempt, the execution of the project was deferred by the re-allocation of funds. In the subsequent attempt in 2004, the execution of this project was postponed due to concerns that an adjacent facility would have to shut down operations during the duration of mobilization and execution of the project and thereby incur potential financial losses. A total of 51 cubic meters (1,800 cubic feet) of demolition debris was generated, which was compliantly disposed of at a local landfill followed by site restoration.

An Evaluation of Molten-Salt Power Towers Including Results of the Solar Two Project  

DOE Green Energy (OSTI)

This report utilizes the results of the Solar Two project, as well as continuing technology development, to update the technical and economic status of molten-salt power towers. The report starts with an overview of power tower technology, including the progression from Solar One to the Solar Two project. This discussion is followed by a review of the Solar Two project--what was planned, what actually occurred, what was learned, and what was accomplished. The third section presents preliminary information regarding the likely configuration of the next molten-salt power tower plant. This section draws on Solar Two experience as well as results of continuing power tower development efforts conducted jointly by industry and Sandia National Laboratories. The fourth section details the expected performance and cost goals for the first commercial molten-salt power tower plant and includes a comparison of the commercial performance goals to the actual performance at Solar One and Solar Two. The final section summarizes the successes of Solar Two and the current technology development activities. The data collected from the Solar Two project suggest that the electricity cost goals established for power towers are reasonable and can be achieved with some simple design improvements.

Instrument performance evaluation  

Science Conference Proceedings (OSTI)

Deficiencies exist in both the performance and the quality of health physics instruments. Recognizing the implications of such deficiencies for the protection of workers and the public, in the early 1980s the DOE and the NRC encouraged the development of a performance standard and established a program to test a series of instruments against criteria in the standard. The purpose of the testing was to establish the practicality of the criteria in the standard, to determine the performance of a cross section of available instruments, and to establish a testing capability. Over 100 instruments were tested, resulting in a practical standard and an understanding of the deficiencies in available instruments. In parallel with the instrument testing, a value-impact study clearly established the benefits of implementing a formal testing program. An ad hoc committee also met several times to establish recommendations for the voluntary implementation of a testing program based on the studies and the performance standard. For several reasons, a formal program did not materialize. Ongoing tests and studies have supported the development of specific instruments and have helped specific clients understand the performance of their instruments. The purpose of this presentation is to trace the history of instrument testing to date and suggest the benefits of a centralized formal program.
