Reduce Air Infiltration in Furnaces (English/Chinese) (Fact Sheet)  

SciTech Connect

Chinese translation of the Reduce Air Infiltration in Furnaces fact sheet. Provides suggestions on how to improve furnace energy efficiency. Fuel-fired furnaces discharge combustion products through a stack or a chimney. Hot furnace gases are less dense and more buoyant than ambient air, so they rise, creating a differential pressure between the top and the bottom of the furnace. This differential, known as thermal head, is the source of a natural draft or negative pressure in furnaces and boilers. A well-designed furnace (or boiler) is built to avoid air leakage into the furnace or leakage of flue gases from the furnace to the ambient. However, with time, most furnaces develop cracks or openings around doors, joints, and hearth seals. These openings (leaks) usually appear small compared with the overall dimensions of the furnace, so they are often ignored. The negative pressure created by the natural draft (or use of an induced-draft fan) in a furnace draws cold air through the openings (leaks) and into the furnace. The cold air becomes heated to the furnace exhaust gas temperature and then exits through the flue system, wasting valuable fuel. It might also cause excessive oxidation of metals or other materials in the furnaces. The heat loss due to cold air leakage resulting from the natural draft can be estimated if you know four major parameters: (1) The furnace or flue gas temperature; (2) The vertical distance H between the opening (leak) and the point where the exhaust gases leave the furnace and its flue system (if the leak is along a vertical surface, H will be an average value); (3) The area of the leak, in square inches; and (4) The amount of operating time the furnace spends at negative pressure. Secondary parameters that affect the amount of air leakage include these: (1) The furnace firing rate; (2) The flue gas velocity through the stack or the stack cross-section area; (3) The burner operating conditions (e.g., excess air, combustion air temperature, and so on). For furnaces or boilers using an induced-draft (ID) fan, the furnace negative pressure depends on the fan performance and frictional losses between the fan inlet and the point of air leakage. In most cases, it would be necessary to measure or estimate negative pressure at the opening. The amount of air leakage, the heat lost in flue gases, and their effects on increased furnace or boiler fuel consumption can be calculated by using the equations and graphs given in Industrial Furnaces (see W. Trinks et al., below). Note that the actual heat input required to compensate for the heat loss in flue gases due to air leakage would be greater than the heat contained in the air leakage because of the effect of available heat in the furnace. For a high-temperature furnace that is not maintained properly, the fuel consumption increase due to air leakage can be as high as 10% of the fuel input.

Delp Publisher Lawrence Berkeley National Laboratory City Berkeley Keywords air flow measurement, air leakage, blower power measurement, blowers, energy performance of buildings group, forced air systems, furnaces, indoor environment department, other, public interest energy research (pier) program, residential hvac Abstract This project evaluated the air leakage and electric power consumption of Residential HVAC components, with a particular focus on air leakage of furnace cabinets. Laboratory testing of HVAC components indicated that air leakage can be significant and highly variable from unit to unit - indicating the need for a standard test method and specifying maximum allowable air leakage in California State energy codes. To further this effort, this project provided technical assistance for the development of a national standard for Residential HVAC equipment air leakage. This standard is being developed by ASHRAE and is called "ASHRAE Standard 193P - Method of test for Determining the Air Leakage Rate of HVAC Equipment". The final part of this project evaluated techniques for measurement of furnace blower power consumption. A draft test procedure for power consumption was developed in collaboration with the Canadian General Standards Board: CSA 823 "Performance Standard for air handlers in residential space conditioning systems".

Advanced furnace air staging and burner modifications for ultra-low NOx firing systems  

SciTech Connect

Overfire air is an effective means to reduce NOx emissions from coal fired furnaces. The current range of overfire air usage on wall-fired boilers in the US is in the range of 10 to 20%. In most cases this is enough to achieve current Title IV NOx reduction requirements. Future applications are likely to go beyond 20% Overfire Air to reduce NOx further for lower investment and operating costs of SCR retrofits. Summer ozone reduction requires NOx emissions of 0.15 lb/MBtu. Currently, industry is exploring the conditions under which this goal is attainable. The paper discussed the approach to achieve ultra-low NOx emissions by using advanced furnace air staging. It describes the unique approach of redesigning the burner to maintain low NOx burner performance when the overfire air system is added or increased in capacity. The impact on furnace corrosion and unburned carbon losses are presented. A case study is used to show the effects of overfire air both on emissions and unburned carbon.

Register Closing Effects on Forced Air Heating System Performance  

SciTech Connect

Closing registers in forced air heating systems and leaving some rooms in a house unconditioned has been suggested as a method of quickly saving energy for California consumers. This study combined laboratory measurements of the changes in duct leakage as registers are closed together with modeling techniques to estimate the changes in energy use attributed to closing registers. The results of this study showed that register closing led to increased energy use for a typical California house over a wide combination of climate, duct leakage and number of closed registers. The reduction in building thermal loads due to conditioning only a part of the house was offset by increased duct system losses; mostly due to increased duct leakage. Therefore, the register closing technique is not recommended as a viable energy saving strategy for California houses with ducts located outside conditioned space. The energy penalty associated with the register closing technique was found to be minimized if registers furthest from the air handler are closed first because this tends to only affect the pressures and air leakage for the closed off branch. Closing registers nearer the air handler tends to increase the pressures and air leakage for the whole system. Closing too many registers (more than 60%) is not recommended because the added flow resistance severely restricts the air flow though the system leading to safety concerns. For example, furnaces may operate on the high-limit switch and cooling systems may suffer from frozen coils.

DOE Patents (OSTI)

A furnace heats through both infrared radiation and convective air utilizing an infrared/purge gas design that enables improved temperature control to enable more uniform treatment of workpieces. The furnace utilizes lamps, the electrical end connections of which are located in an enclosure outside the furnace chamber, with the lamps extending into the furnace chamber through openings in the wall of the chamber. The enclosure is purged with gas, which gas flows from the enclosure into the furnace chamber via the openings in the wall of the chamber so that the gas flows above and around the lamps and is heated to form a convective mechanism in heating parts.

Advanced steel reheat furnace  

SciTech Connect

Energy and Environmental Research Corp. (EER) under a contract from the Department of Energy is pursuing the development and demonstration of an Advanced Steel Reheating Furnace. This paper reports the results of Phase 1, Research, which has evaluated an advanced furnace concept incorporating two proven and commercialized technologies previously applied to other high temperature combustion applications: EER`s gas reburn technology (GR) for post combustion NOx control; and Air Product`s oxy-fuel enrichment air (OEA) for improved flame heat transfer in the heating zones of the furnace. The combined technologies feature greater production throughput with associated furnace efficiency improvements; lowered NOx emissions; and better control over the furnace atmosphere, whether oxidizing or reducing, leading to better control over surface finish.

Geothermal-resource verification for Air Force bases  

SciTech Connect

This report summarizes the various types of geothermal energy reviews some legal uncertainties of the resource and then describes a methodology to evaluate geothermal resources for applications to US Air Force bases. Estimates suggest that exploration costs will be $50,000 to $300,000, which, if favorable, would lead to drilling a $500,000 exploration well. Successful identification and development of a geothermal resource could provide all base, fixed system needs with an inexpensive, renewable energy source.

Waste management issues at US Air Force bases  

SciTech Connect

Air Force installations are industrial bases for projecting men and machinery around the globe. Supporting this mission typically requires large quantities of stockpiled potentially hazardous materials. Over the past several decades, spills, poor accounting, mis-handling, and lack of understanding have led to discharges of hazardous substances into the environment. The Installation Restoration Program (IRP) is a Department of Defense directed program aimed at remediating discharges of hazardous substances, POL (petroleum, oil, and lubricants), and solid waste disposal at defense installations. The IRP is broader in scope than even the US EPA Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), and requires the Air Force managers to integrate their programs with a broad range of regulations (See Table 1 below). Managing the wastes generated by the remediation program is one of the unexpected problems the Air Force has faced in their remediation efforts. The traditional approach to remediating sites in the US has been to remove the material and place it in a secure landfill, or in the case of groundwater, to pump and treat the effluent. These technologies have proven to be very expensive and don`t really fix the problem. The waste is just moved from one place to another. Moreover, these policies ignore a fundamental technology available to today`s environmental managers: waste minimization.

Cape Canaveral Air Force Station integrated resource assessment. Volume 3, Resource assessment  

SciTech Connect

The U.S. Air Force (USAF) has tasked the Pacific Northwest Laboratory (PNL) in support of the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP), to identify, evaluate, and assist in acquiring all cost-effective energy projects at Cape Canaveral Air Force Station (AFS). Projects considered can be either in the form of energy management or energy conservation. The overall efforts of this task are based on a model program PNL is designing to support energy-use decisions in the federal sector. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at Cape Canaveral AFS, which is located approximately 10 miles north of Cocoa Beach, Florida. It is a companion report to Volume 1: Executive Summary and Volume 2: Baseline Detail. The results of the analyses of EROs are presented in 11 common energy end-use categories (e.g., boilers and furnaces, service hot water, and building lighting). A narrative description of each ERO is provided, including information on the installed cost, energy and dollar savings, impacts on operations and maintenance (O&M), and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. Descriptions of the evaluation methodologies and technical and cost assumptions are also provided for each ERO. Summary tables present the cost- effectiveness of energy end-use equipment before and after the implementation of each ERO and present the results of the life-cycle cost (LCC) analysis, indicating the net present value (NPV) and savings-to-investment ratio (SIR) of each ERO.

A Furnace Temperature Regulator  

Science Journals Connector (OSTI)

Synopsis.By making the heating coil of an electric furnace one arm of a wheatstone bridge, and combining this with a galvanometer regulator, thus keeping constant the resistance of the coil, we can, regardless of variations in the current supply, and with no attention, maintain constant the temperature of furnaces not too directly influenced by the temperature of the room, or where the surrounding air is kept constant. The power available in this regulator is relatively very great indeed; nothing has to be inserted within the furnace cavity, and the lag is practically nothing; the regulator is often almost at its best under conditions most unfavorable to other regulators. It has held a small furnace constant to 0.1 for hours at temperatures from 500 to 1400.

Upgrading to a high efficiency furnace or boiler is an effective way to save money on home heating. What does this mean for me? To maintain your heating system's efficiency and ensure healthy indoor air quality, it's critical to maintain the unit and its venting mechanism. Proper maintenance extends the life of your furnace or boiler and saves you money. Most U.S. homes are heated with either furnaces or boilers. Furnaces heat air and distribute the heated air through the house using ducts. Boilers heat water, and provide either hot water or steam for heating.

Blast furnace taphole drill  

SciTech Connect

A blast furnace taphole drill has a flaring head with cutting edges at its cutting end formed by intersecting angled faces. A central bore carries cleaning air to the cutting end. To prevent blockage of the cleaning air bore by debris and possible jamming of the drill, the head has deep radial grooves formed at the bottoms of the valley shapes between the cutting edges. The grooves extend radially from the air bore and conduct the air so that it can get behind or under jammed debris. Reduced taphole drilling times can be achieved.

SciTech Connect

The Sitewide Feasibility Study (FS) is required under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the National Contingency Plan (NCP), and the Federal Facility Agreement (FFA) for Eielson Air Force Base (AFB). It is based on findings presented in the Sitewide Remedial Investigation (RI) Report (USAF 1995a), and the Sitewide Baseline Risk Assessment (BLRA) Report (USAF 1995b). Under the FFA, 64 potential source areas were placed in one of six operable units, based on similar contaminant and environmental characteristics, or were included for evaluation under a Source Evaluation Report (SER). The sitewide RI was directed at contamination that was not confined to an operable unit (OU) or SER source area. The objectives of the sitewide RI were to: Provide information about site characteristics to support individual OU RI/FS efforts and the sitewide RI/FS, including site hydrogeology and determination of background soil and groundwater characteristics; identify and characterize contamination that is not confined or attributable to a specific source area through sitewide monitoring of groundwater and surface water; evaluate cumulative risks to human health and the environment from contamination on a sitewide basis; and provide a mechanism for continued cohesive sitewide monitoring.

Economic analysis of coal-fired cogeneration plants for Air Force bases  

SciTech Connect

The Defense Appropriations Act of 1986 requires the Department of Defense to use an additional 1,600,000 tons/year of coal at their US facilities by 1995 and also states that the most economical fuel should be used at each facility. In a previous study of Air Force heating plants burning gas or oil, Oak Ridge National Laboratory found that only a small fraction of this target 1,600,000 tons/year could be achieved by converting the plants where coal is economically viable. To identify projects that would use greater amounts of coal, the economic benefits of installing coal-fired cogeneration plants at 7 candidate Air Force bases were examined in this study. A life-cycle cost analysis was performed that included two types of financing (Air Force and private) and three levels of energy escalation for a total of six economic scenarios. Hill, McGuire, and Plattsburgh Air Force Bases were identified as the facilities with the best potential for coal-fired cogeneration, but the actual cost savings will depend strongly on how the projects are financed and to a lesser extent on future energy escalation rates. 10 refs., 11 figs., 27 tabs.

Mountain Home Air Force Base, Idaho Geothermal Resource Assessment and Future Recommendations  

SciTech Connect

The U.S. Air Force is facing a number of challenges as it moves into the future, one of the biggest being how to provide safe and secure energy to support base operations. A team of scientists and engineers met at Mountain Home Air Force Base in early 2011 near Boise, Idaho, to discuss the possibility of exploring for geothermal resources under the base. The team identified that there was a reasonable potential for geothermal resources based on data from an existing well. In addition, a regional gravity map helped identify several possible locations for drilling a new well. The team identified several possible sources of funding for this wellthe most logical being to use U.S. Department of Energy funds to drill the upper half of the well and U.S. Air Force funds to drill the bottom half of the well. The well was designed as a slimhole well in accordance with State of Idaho Department of Water Resources rules and regulations. Drilling operations commenced at the Mountain Home site in July of 2011 and were completed in January of 2012. Temperatures increased gradually, especially below a depth of 2000 ft. Temperatures increased more rapidly below a depth of 5500 ft. The bottom of the well is at 5976 ft, where a temperature of about 140C was recorded. The well flowed artesian from a depth below 5600 ft, until it was plugged off with drilling mud. Core samples were collected from the well and are being analyzed to help understand permeability at depth. Additional tests using a televiewer system will be run to evaluate orientation and directions at fractures, especially in the production zone. A final report on the well exploitation will be forthcoming later this year. The Air Force will use it to evaluate the geothermal resource potential for future private development options at Mountain Home Air Force Base. In conclusion, Recommendation for follow-up efforts include the following:

Innovative pollution prevention program at Air Force owned Raytheon operated facility incorporating Russian technology  

SciTech Connect

Air Force Plant 44 in Tucson, Arizona is owned by the Air Force and operated by Raytheon Missile Systems Company. A joint Air Force/Raytheon Pollution Prevention Team operates at AFP 44 with the ultimate goal to minimize or eliminate the use of hazardous substances. The team works together to uncover new technologies and methods that will replace chemicals used in the plant's missile manufacturing facilities. The program maximizes pollution prevention by first eliminating hazardous material use, then chemical recycling, next hazardous waste reduction and finally wastewater treatment and recycling. From fiscal years 1994 through 1997, nine pollution prevention projects have been implemented, totaling $2.6 million, with a payback averaging less than two years. A unique wastewater treatment method has been demonstrated as part of this program. This is electroflotation, a Russian technology which removes dispersed particles from liquid with gas bubbles obtained during water electrolysis. A unit was built in the US which successfully removed organic emulsions from wastewater. Operational units are planned for the removal of waste from waterfall paint booths. The pollution prevention joint team continues to be very active with two projects underway in FY 98 and two more funded for FY 99.

Nitrogen oxide emissions from a kraft recovery furnace  

SciTech Connect

Nitrogen Oxide (NOx) emissions from a rebuilt kraft recovery furnace slightly exceeded the specified limit of 1.1 lb/ton (0.55 kg/metric ton) of black-liquor solids. Mill trials were undertaken to determine whether NOx emissions could be minimized by modifying furnace operation. NOx emissions increased when secondary air was shifted to tertiary ports. NOx emissions fell when the amounts of primary and total air were decreased, but this increased emissions of other pollutants. After demonstrating that best operation of the furnace could not meet the permit with an emissions limit that matched the furnace's performance at best operation.

Remaining Life Related Issues Being Pursued at DRDO for Indian Air Force  

Science Journals Connector (OSTI)

Abstract Hot section components of an aircraft gas turbine engine are critical to the performance and safety during the operation of military aircraft, where the service spectra are highly random and relatively severe in terms of the loading rates. DMRL, in collaboration with Indian Air Force (IAF), has initiated a project for the estimation of remaining life as well as life extension of military aeroengines of various origins. This is based on extensive laboratory specimen-level material characterization in terms of fatigue and creep, followed by the scale-up of experimental results to actual component. Finite Element Analysis (FEA) is an indispensable engineering tool for evaluation of the mechanical variables that determine crack initiation and growth, apart from material degradation prior to physical failure. DMRL's understanding and experience with FEA applications and damage mechanics concepts in these areas are briefly discussed in this paper.

Vandenberg Air Force Base integrated resource assessment. Volume 2, Baseline detail  

SciTech Connect

The US Air Force Space Command has tasked the Pacific Northwest Laboratory, as the lead laboratory supporting the US Department of Energy Federal Energy Management Program, to identify, evaluate, and assist in acquiring all cost-effective energy projects at Vandenberg Air Force Base (VAFB). This is a model program PNL is designing for federal customers served by the Pacific Gas and Electric Company (PG and E). The primary goal of the VAFB project is to identify all electric energy efficiency opportunities, and to negotiate with PG and E to acquire those resources through a customized demand-side management program for its federal clients. That customized program should have three major characteristics: (1) 100% up-front financing; (2) substantial utility cost-sharing; and (3) utility implementation through energy service companies under contract to the utility. A similar arrangement will be pursued with Southern California Gas for non-electric resource opportunities if that is deemed desirable by the site and if the gas utility seems open to such an approach. This report documents the assessment of baseline energy use at VAFB located near Lompoc, California. It is a companion report to Volume 1, Executive Summary, and Volume 3, Resource Assessment. This analysis examines the characteristics of electric, natural gas, fuel oil, and propane use for fiscal year 1991. It records energy-use intensities for the facilities at VAFB by building type and energy end use. It also breaks down building energy consumption by fuel type, energy end use, and building type. A more complete energy consumption reconciliation is presented that includes the accounting of all energy use among buildings, utilities, and applicable losses.

Geothermal Evaluation of The Hosston Formation Lackland Air Force Base, San Antonio, Texas Phase II Report  

SciTech Connect

This report summarizes the results of a phased program to test the geothermal characteristics of the Hosston Formation at Lackland Air Force Base, San Antonio, Texas. The geothermal resource evaluation was made possible through drilling and preliminary testing of a large diameter well, Lackland AFB No.1, at the south portion of the base. Phase I of the program had 3 major components: (1) compilation and interpretation of surface and subsurface geologic data to site the well; (2) design of the well; and (3) permitting the well. Phase II consisted of well drilling and preliminary development. The goal of the program was to identify water temperature, water quality, and productivity characteristics of the Hosston aquifer, which preliminary studies suggested might be favorable for direct applications on the base. Results reported herein suggest that heat pumps or other engineering alternatives might be needed for such applications. Results of the well drilling give data on water productivity, quality and temperature. Air-lift testing shows that, although the well does not flow to surface, good artesian pressure exists. Water quality appears acceptable, with about 2200 parts per million total dissolved solids. Equilibrated reservoir temperatures appear to be slightly less than 108 F (42 C).

A stove or furnace for efficient combustion of wood fuel includes a vertical feed combustion chamber (15) for receiving and supporting wood fuel in a vertical attitude or stack. A major upper portion of the combustion chamber column comprises a water jacket (14) for coupling to a source of water or heat transfer fluid for convection circulation of the fluid. The locus (31) of wood fuel combustion is thereby confined to the refractory base of the combustion chamber. A flue gas propagation delay channel (34) extending laterally from the base of the chamber affords delayed travel time in a high temperature refractory environment sufficient to assure substantially complete combustion of the gaseous products of wood burning with forced air prior to extraction of heat in heat exchanger (16). Induced draft draws the fuel gas and air mixture laterally through the combustion chamber and refractory high temperature zone to the heat exchanger and flue. Also included are active sources of forced air and induced draft, multiple circuit couplings for the recovered heat, and construction features in the refractory material substructure and metal component superstructure.

(Environmental investigation of ground water contamination at Wright-Patterson Air Force Base, Ohio)  

SciTech Connect

In April 1990, Wright-Patterson Air Force Base (WPAFB), initiated an investigation to evaluate a potential Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) removal action to prevent, to the extent practicable, the offsite migration of contaminated ground water from WPAFB. WPAFB retained the services of the Environmental Management Operations (EMO) and its principle subcontractor, International Technology Corporation (IT) to complete Phase 1 of the environmental investigation of ground-water contamination at WPAFB. Phase 1 of the investigation involves the short-term evaluation and potential design for a program to remove ground-water contamination that appears to be migrating across the western boundary of Area C, and across the northern boundary of Area B along Springfield Pike. Primarily, Task 4 of Phase 1 focuses on collection of information at the Area C and Springfield Pike boundaries of WPAFB. This Sampling and Analysis Plan (SAP) has been prepared to assist in completion of the Task 4 field investigation and is comprised of the Quality Assurance Project Plan (QAPP) and the Field Sampling Plan (FSP).

Comparison of energy assessment methods and tools at Bolling Air Force Base  

SciTech Connect

A plethora of energy efficiency assessment tools have been designed for federal installations, identifying the energy savings potential and attractive projects for capital investment. These methods range from high-level estimating tools to detailed design tools, both manual and software assisted. These methods have different purposes and provide results that are used for different parts of the project identification and implementation process. This paper`s objective is to compare and contrast a number of energy efficiency assessment methods and tools based on their application to a selected set of buildings at Bolling Air Force Base (AFB). To some extent this comparison is much like a {open_quote}Consumer Report{close_quotes} evaluation of the various assessment methods, comparing the features and potential uses of each. Because of the range of methods included, direct comparison of the quantitative results at Bolling AFB was limited to two or three methods at a time which were applied to the same buildings and/or technologies. The results are largely a qualitative comparison of the capabilities of each method, where they can and should be used to identify and implement projects, how much it costs to use the methods, and the type of output to expect. This comparison should be of value to energy managers at federal sites that need to select the appropriate tools to use in assessing energy opportunities.

Laboratory Evaluation of Residential Furnace BlowerPerformance  

SciTech Connect

A testing program was undertaken at Lawrence Berkeley National Laboratory and an electric utility (Pacific Gas and Electric Co.) to compare the performance of furnace blowers. This laboratory testing program was undertaken to support potential changes to California Building Standards regarding in-field furnace blower energy use. This technical support includes identifying suitable performance metrics and target performance levels for use in standards. Five different combinations of blowers and residential furnaces were tested for air moving performance. Three different types of blower and motor combinations were tested in two different furnace cabinets. The blowers were standard forward--curved impellors and a prototype impeller with reverse-inclined blades. The motors were two 6-pole permanent split capacitor (PSC) single-phase induction motors, a brushless permanent magnet (BPM) motor and a prototype BPM designed for use with a prototype reverse-inclined impellor. The laboratory testing operated each blower and furnace combination over a range of air flows and pressure differences to determine air flow performance, power consumption and efficiency. Additional tests varied the clearance between the blower housing and the furnace cabinet, and the routing of air flow into the blower cabinet.

Improved graphite furnace atomizer  

DOE Patents (OSTI)

A graphite furnace atomizer for use in graphite furnace atomic absorption spectroscopy is described wherein the heating elements are affixed near the optical path and away from the point of sample deposition, so that when the sample is volatilized the spectroscopic temperature at the optical path is at least that of the volatilization temperature, whereby analyteconcomitant complex formation is advantageously reduced. The atomizer may be elongated along its axis to increase the distance between the optical path and the sample deposition point. Also, the atomizer may be elongated along the axis of the optical path, whereby its analytical sensitivity is greatly increased.

Geologic investigation :an update of subsurface geology on Kirtland Air Force Base, New Mexico.  

SciTech Connect

The objective of this investigation was to generate a revised geologic model of Kirtland Air Force Base (KAFB) incorporating the geological and geophysical data produced since the Site-Wide Hydrogeologic Characterization Project (SWHC) of 1994 and 1995. Although this report has certain stand-alone characteristics, it is intended to complement the previous work and to serve as a status report as of late 2002. In the eastern portion of KAFB (Lurance Canyon and the Hubbell bench), of primary interest is the elevation to which bedrock is buried under a thin cap of alluvium. Elevation maps of the bedrock top reveal the paleodrainage that allows for the interpretation of the area's erosional history. The western portion of KAFB consists of the eastern part of the Albuquerque basin where bedrock is deeply buried under Santa Fe Group alluvium. In this area, the configuration of the down-to-the-west, basin-bounding Sandia and West Sandia faults is of primary interest. New geological and geophysical data and the reinterpretation of old data help to redefine the location and magnitude of these elements. Additional interests in this area are the internal stratigraphy and structure of the Santa Fe Group. Recent data collected from new monitoring wells in the area have led to a geologic characterization of the perched Tijeras Arroyo Groundwater system and have refined the known limits of the Ancestral Rio Grande fluvial sediments within the Santa Fe Group. Both the reinterpretation of the existing data and a review of the regional geology have shown that a segment of the boundary between the eastern and western portions of KAFB is a complicated early Tertiary (Laramide) wrench-fault system, the Tijeras/Explosive Ordnance Disposal Area/Hubbell Spring system. A portion of this fault zone is occupied by a coeval ''pull-apart'' basin filled with early Tertiary conglomerates, whose exposures form the ''Travertine Hills''.

Aeronautical System Center's environmental compliance assessment and management program's cost-saving initiatives support the Air Force's acquisition reform initiative  

SciTech Connect

The Environmental Management directorate of ASC (ASC/EM) has the responsibility of providing government oversight for the Government Owned Contractor Operated Aircraft and Missile plants (GOCOs). This oversight is manifested as a landlord role where Air Force provides the funding required to maintain the plant facilities including buildings and utilities as well as environmental systems. By agreement the companies operating the plants are required to operate them in accordance with environmental law. Presently the GOCOs include Air Force Plant (AFP) 6 in Marietta Ga., AFP 4 in Fort Worth, Tx., AFP 44 in Tucson, Az., AFP 42 in Palmdale, Ca., and AFP PJKS in Denver, Co. Lockheed Martin corporation operates AFPs 4,6, PJKS and a portion of AFP 42 while AFP 44 is operated by Raytheon Missile Systems Company. Other GOCOs at AFP 42 are Northrup-Grumman, Boeing, and Cabaco, the facilities engineer. Since 1992 the Environmental Management division has conducted its Environmental Compliance Assessment and Management Program assessments (ECAMP) annually at each of the plants. Using DOD's ECAMP Team Guide and teams comprised of both Air Force and consultant engineering personnel, each plant is assessed for its environmental compliance well being. In the face of rising operational costs and diminishing budgets ASC/EM performed a comprehensive review of its ECAMP. As a result, the basic ECAMP program was improved to reduce costs without compromising on quality of the effort. The program retained its emphasis in providing a snap-shot evaluation of each Air Force plant's environmental compliance health supported by complete but tailored protocol assessments.

Furnace and Heat Recovery Area Design and Analysis for Conceptual Design of Oxygen-Based PC Boiler  

SciTech Connect

The objective of the furnace and heat recovery area design and analysis task of the Conceptual Design of Oxygen-Based PC Boiler study is to optimize the location and design of the furnace, burners, over-fire gas ports, and internal radiant surfaces. The furnace and heat recovery area were designed and analyzed using the FW-FIRE and HEATEX computer programs. The furnace is designed with opposed wall-firing burners and over-fire air ports. Water is circulated in the furnace by natural circulation to the waterwalls and divisional wall panels. Compared to the air-fired furnace, the oxygen-fired furnace requires only 65% of the surface area and 45% of the volume. Two oxygen-fired designs were simulated: (1) without over-fire air and (2) with 20% over-fire air. The maximum wall heat flux in the oxygen-fired furnace is more than double that of the air-fired furnace due to the higher flame temperature and higher H{sub 2}O and CO{sub 2} concentrations. The coal burnout for the oxygen-fired case is 100% due to a 500 F higher furnace temperature and higher concentration of O{sub 2}. Because of the higher furnace wall temperature of the oxygen-fired case compared to the air-fired case, furnace water wall material was upgraded from carbon steel to T91. The total heat transfer surface required in the oxygen-fired heat recovery area (HRA) is 25% less than the air-fired HRA due to more heat being absorbed in the oxygen-fired furnace and the greater molecular weight of the oxygen-fired flue gas. The HRA tube materials and wall thickness are practically the same for the air-fired and oxygen-fired design since the flue gas and water/steam temperature profiles encountered by the heat transfer banks are very similar.

Utilization of computational fluid dynamics technique in low NOx burner/furnace retrofits  

SciTech Connect

A computational fluid dynamics (CFD) technique has been utilized to provide design guidance for retrofitting low NOx combustion systems and incorporating associated furnace modifications into existing utility boilers. The CFD program utilized is FW-FIRES (Fossil fuel, Water-walled Furnace Integrated Reaction and Emission Simulation) which simulates furnace combustion, heat transfer and pollutant formation based on fundamental principals of mass, momentum and energy conservations. The program models the gas flow field as a three-dimensional turbulent reacting continuum and the particle flow as a series of discrete particle trajectories through the gas continuum. Chemical reaction, heat transfer, and pollutant formation mechanisms are incorporated in the program. FW-FIRES furnace simulation of low NOx combustion system retrofits has been performed for various furnace configurations including front wall-fired, front and real wall-fired, and tangentially-fired furnaces, to determine the effects of burner/furnace modifications on the NOx emission, furnace exit gas temperature, furnace heat absorption, unburned carbon, and furnace wall corrosion. For front wall-fired, and front and real wall-fired furnaces, the NOx emission requirement is met by the use of Foster Wheeler lox NOx burners and overfire air (OFA) staging. Studies of burner and OFA quantify and spacing are conducted to limit NOx emission and unburned carbon to acceptable levels. A major concern in once-through supercritical units with OFA is furnace wall corrosion which is caused by high furnace wall metal temperature and corrosive hydrogen sulfide (H{sub 2}S) created in a reducing atmosphere from part of coal sulfur. The FW-FIRES code is used to minimize this corrosion potential by selecting the proper location and quantity of boundary air. A simulation of tangentially-fired unit, which has been retrofitted with low NOx burners, is used to study the effect of the burner tilt on the furnace exit gas temperature. This paper details the basis and results of several CFD analyses conducted for potential retrofit programs.

CFD modelling of air-fired and oxy-fuel combustion in a large-scale furnace at Loy Yang A brown coal power station  

Science Journals Connector (OSTI)

Oxy-fuel combustion technique is a viable option to reduce several types of greenhouse gases (GHGs) emissions from the pulverized coal (PC) combustion systems. In this paper, a computational fluid dynamics (CFD) modelling study has been developed in order to investigate the Victorian brown coal combustion in a 550MW utility boiler under the air-fired (reference case) and three oxy-fuel-fired scenarios. The reference firing case was modelled based on the operating conditions of Loy Yang A power plant located in the state of Victoria, Australia. While Chalmers oxy-fuel combustion approach was selected for the present oxy-fuel combustion simulations, which referred to as OF25 (25vol.% O2), OF27 (27vol.% O2), and OF29 (29vol.% O2). User-defined functions (UDFs) were written and incorporated into the CFD code to calculate the following mathematical models: the PC devolatilization, char burnout, multi-step chemical reactions, mass and heat transfer, carbon in fly-ash, and \\{NOx\\} formation/destruction. A level of confidence of the CFD model was achieved validating four different parameters of the conventional combustion case, as well as the previous preliminary CFD studies that conducted on a 100kW unit firing propane and lignite under oxy-fuel combustion environments. The numerical results of OF29 combustion condition were considerably similar to the reference firing results in terms of gas temperature levels and radiative heat transfer relative to the OF25 and OF27 combustion cases. This similarity was due to increasing the residence time of PC in the combustion zone and O2-enriched in feed oxidizer gases. A significant increase in the CO2 concentrations and a noticeable decrease in the \\{NOx\\} formation were observed under all oxy-fuel combustion scenarios. The combustion chemistry was adopted in these investigations in order to capture the effects of O2 concentrations and gas temperatures on the CO/CO2 production rate and equilibrium between H2 and H2O in the combustion zone. Also, the use of O2-enriched atmospheres during oxy-fuel-fired cases was slightly enhanced the carbon burnout rate. These predicted results were reasonably consistent with the experimental investigations and numerical modelling found in the literature. This study of Victorian brown coal oxy-fuel combustion in a large-scale tangentially-fired boiler is important prior to its implementation in real-life.

Thermal investigation of lithium-ion battery module with different cell arrangement structures and forced air-cooling strategies  

Science Journals Connector (OSTI)

Abstract Thermal management needs to be carefully considered in the lithium-ion battery module design to guarantee the temperature of batteries in operation within a narrow optimal range. This article firstly explores the thermal performance of battery module under different cell arrangement structures, which includes: 1נ24, 3נ8 and 5נ5 arrays rectangular arrangement, 19 cells hexagonal arrangement and 28 cells circular arrangement. In addition, air-cooling strategies are also investigated by installing the fans in the different locations of the battery module to improve the temperature uniformity. Factors that influence the cooling capability of forced air cooling are discussed based on the simulations. The three-dimensional computational fluid dynamics (CFD) method and lumped model of single cell have been applied in the simulation. The temperature distributions of batteries are quantitatively described based on different module patterns, fan locations as well as inter-cell distance, and the conclusions are arrived as follows: when the fan locates on top of the module, the best cooling performance is achieved; the most desired structure with forced air cooling is cubic arrangement concerning the cooling effect and cost, while hexagonal structure is optimal when focus on the space utilization of battery module. Besides, the optimized inter-cell distance in battery module structure has been recommended.

Non-carbon induction furnace  

DOE Patents (OSTI)

The present invention is directed to an induction furnace for melting and casting highly pure metals and alloys such as uranium and uranium alloys in such a manner as to minimize contamination of the melt by carbon derived from the materials and the environment within the furnace. The subject furnace is constructed of non-carbon materials and is housed within a conventional vacuum chamber. The furnace comprises a ceramic oxide crucible for holding the charge of metal or alloys. The heating of the crucible is achieved by a plasma-sprayed tungsten susceptor surrounding the crucible which, in turn, is heated by an rf induction coil separated from the susceptor by a cylinder of inorganic insulation. The furnace of the present invention is capable of being rapidly cycled from ambient temperatures to about 1650/sup 0/C for effectively melting uranium and uranium alloys without the attendant carbon contamination problems previously encountered when using carbon-bearing furnace materials.

Preliminary Assessment of Potential Avian Interactions at Four Proposed Wind Energy Facilities on Vandenberg Air Force Base, California  

SciTech Connect

The United States Air Force (USAF) is investigating whether to install wind turbines to provide a supplemental source of electricity at Vandenberg Air Force Base (VAFB) near Lompoc, California. As part of that investigation, VAFB sought assistance from the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) to provide a preliminary characterization of the potential risk to wildlife resources (mainly birds and bats) from wind turbine installations. With wind power development expanding throughout North America and Europe, concerns have surfaced over the number of bird fatalities associated with wind turbines. Guidelines developed for the wind industry by the National Wind Coordinating Committee (NWCC) recommend assessing potential impacts to birds, bats, and other potentially sensitive resources before construction. The primary purpose of an assessment is to identify potential conflicts with sensitive resources, to assist developers with identifying their permitting needs, and to develop strategies to avoid impacts or to mitigate their effects. This report provides a preliminary (Phase I) biological assessment of potential impacts to birds and bats that might result from construction and operation of the proposed wind energy facilities on VAFB.

Hydrologic transport of depleted uranium associated with open air dynamic range testing at Los Alamos National Laboratory, New Mexico, and Eglin Air Force Base, Florida  

SciTech Connect

Hydrologic investigations on depleted uranium fate and transport associated with dynamic testing activities were instituted in the 1980`s at Los Alamos National Laboratory and Eglin Air Force Base. At Los Alamos, extensive field watershed investigations of soil, sediment, and especially runoff water were conducted. Eglin conducted field investigations and runoff studies similar to those at Los Alamos at former and active test ranges. Laboratory experiments complemented the field investigations at both installations. Mass balance calculations were performed to quantify the mass of expended uranium which had transported away from firing sites. At Los Alamos, it is estimated that more than 90 percent of the uranium still remains in close proximity to firing sites, which has been corroborated by independent calculations. At Eglin, we estimate that 90 to 95 percent of the uranium remains at test ranges. These data demonstrate that uranium moves slowly via surface water, in both semi-arid (Los Alamos) and humid (Eglin) environments.

Lutz, Alexander B. Lekov, and Lixing Gu Document Number LBNL-417E Pagination 14 Date Published August 1 Publisher Lawrence Berkeley National Laboratory City Berkeley Abstract Currently, total electricity consumption of furnaces is unregulated, tested at laboratory conditions using the DOE test procedure, and is reported in the GAMA directory as varying from 76 kWh/year to 1,953 kWh/year. Furnace blowers account for about 80% of the total furnace electricity consumption and are primarily used to distribute warm air throughout the home during furnace operation as well as distribute cold air during air conditioning operation. Yet the furnace test procedure does not provide a means to calculate the electricity consumption during cooling operation or standby, which account for a large fraction of the total electricity consumption. Furthermore, blower electricity consumption is strongly affected by static pressure. Field data shows that static pressure in the house distribution ducts varies widely and that the static pressureused in the test procedure as well as the calculated fan power is not representative of actual field installations. Therefore, accurate determination of the blower electricity consumption is important to address electricity consumption of furnaces and air conditioners. This paper compares the potential regional and national energy savings of two-stage brushless permanent magnet (BPM) blower motors (the blower design option with the most potential savings that is currently available in the market) to single-stage permanent split capacitor (PSC) blower motors (the most common blower design option). Computer models were used to generate the heating and cooling loads for typical homes in 16 different climates which represent houses throughout the United States. The results show that the potential savings of using BPM motors vary by region and house characteristics, and are very strongly tied to improving house distribution ducts. Savings decrease dramatically with increased duct pressure. Cold climate locations will see savings even in the high static pressure duct situations, whilewarm climate locations will see less savings overall and negative savings in the high static pressure duct situations. Moderate climate locations will see little or no savings.

James Lutz, Victor Franco, Alex Lekov, and Gabrielle Wong-Parodi Lawrence Berkeley National Laboratory, Berkeley, California ABSTRACT Residential gas furnaces contain blowers to distribute warm air. Currently, furnace blowers use either a Permanent Split Capacitor (PSC) or a Brushless Permanent Magnet (BPM) motor. Blowers account for the majority of furnace electricity consumption. Therefore, accurate determination of the blower electricity consumption is important for understanding electricity consumption of furnaces. The electricity consumption of blower motors depends on the static pressure across the blower. This paper examines both types of blower motors in non-condensing non-weatherized

Corrective Action Investigation Plan for Corrective Action Unit 486: Double Tracks RADSAFE Area Nellis Air Force Range, Nevada  

SciTech Connect

This Corrective Action Investigation Plan (CAIP) has been developed in accordance with the Federal Facility Agreement and Consent Order (FFACO) that was agreed to by the US Department of Energy, Nevada Operations Office (DOE/NV); the State of Nevada Division of Environmental Protection (NDEP); and the US Department of Defense (FFACO, 1996). The CAIP is a document that provides or references all of the specific information for investigation activities associated with Corrective Action Units (CAUs) or Corrective Action Sites (CASs). According to the FFACO, CASs are sites potentially requiring corrective action(s) and may include solid waste management units or individual disposal or release sites (FFACO, 1996). Corrective Action Units consist of one or more CASs grouped together based on geography, technical similarity, or agency responsibility for the purpose of determining corrective actions. This CAIP contains the environmental sample collection objectives and the criteria for conducting site investigation activities at CAU 486, the Double Tracks Radiological Safety (RADSAFE) Area (DTRSA) which is located on the Nellis Air Force Range 71North (N), west of the Tonopah Test Range (TTR). The TTR, included in the Nellis Air Force Range Complex, is approximately 255 kilometers (km) (140 miles [mi]) northwest of Las Vegas, Nevada (Figure 1-1). Corrective Action Unit 486 is comprised of CAS 71-23-001-71DT consisting of two areas of concern referred to as the vehicle decontamination area and the animal burial pit. The DTRSA is located on the west side of the Cactus Range approximately 8 km (5 mi) southwest of the Cactus Spring gate at the intersection of the Cactus Spring Road and the Double Tracks Control Point Road (Figure 1-2). The DTRSA was used during May 1963 to decontaminate vehicles, equipment, personnel, and animals from the Double Tracks test. The DTRSA is one of three areas identified as a potential location for the disposal of radioactively contaminated materials from the Double Tracks experiment. The other two locations are the Cactus Spring Waste Trenches (CAU 426) and the Roller Coaster RADSAFE Area (CAU 407), both of which have been investigated. The surface and subsurface soils are likely to have been impacted by plutonium and other contaminants of potential concern (COPCs) associated with decontamination activities at this site.

BPM Motors in Residential Gas Furnaces: What are theSavings?  

SciTech Connect

Residential gas furnaces contain blowers to distribute warm air. Currently, furnace blowers use either a Permanent Split Capacitor (PSC) or a Brushless Permanent Magnet (BPM) motor. Blowers account for the majority of furnace electricity consumption. Therefore, accurate determination of the blower electricity consumption is important for understanding electricity consumption of furnaces. The electricity consumption of blower motors depends on the static pressure across the blower. This paper examines both types of blower motors in non-condensing non-weatherized gas furnaces at a range of static pressures. Fan performance data is based on manufacturer product literature and laboratory tests. We use field-measured static pressure in ducts to get typical system curves to calculate how furnaces would operate in the field. We contrast this with the electricity consumption of a furnace blower operating under the DOE test procedure and manufacturer rated conditions. Furnace electricity use is also affected by operating modes that happen at the beginning and end of each furnace firing cycle. These operating modes are the pre-purge and post-purge by the draft inducer, the on-delay and off-delay of the blower, and the hot surface ignitor operation. To accurately calculate this effect, we use the number of firing cycles in a typical California house in the Central Valley of California. Cooling hours are not considered in the DOE test procedure. We also account for furnace blower use by the air conditioner and stand-by power. Overall BPM motors outperform PSC motors, but the total electricity savings are significantly less than projected using the DOE test procedure conditions. The performance gains depend on the static pressure of the household ducts, which are typically much higher than in the test procedures.

Radiation control coatings installed on federal buildings at Tyndall Air Force Base. Volume 2: Long-term monitoring and modeling  

SciTech Connect

The US Department of Energy`s (DOE`s) Federal Energy Management Program (FEMP) supports efforts to reduce energy use and associated expenses in the federal sector. One such effort, the New Technology Demonstration Program (NTDP), seeks to evaluate new energy-saving US technologies and secure their more timely adoption by the US government. Through a partnership with a federal site, the utility serving the site, a manufacturer of an energy-related technology, and other organizations associated with these interests, DOE can evaluate a new technology. The results of the program give federal agency decision makers more hands-on information with which to validate a decision to utilize a new technology in their facilities. This is the second volume of a two-volume report that describes the effects of radiation control coatings installed on federal buildings at Tyndall Air Force Base (AFB) in Florida by ThermShield International. ORNL`s Buildings Technology Center (BTC) was assigned the responsibility for gathering, analyzing, and reporting on the data to describe the effects of the coatings. The first volume described the monitoring plan and its implementation, the results of pre-coating monitoring, the coating installation, results from fresh coatings compared to pre-coating results, and a plan to decommission the monitoring equipment. This second volume updates and completes the presentation of data to compare performance of fresh coatings with weathered coatings.

Improving the Field Performance of Natural Gas Furnaces, Chicago, Illinois (Fact Sheet)  

SciTech Connect

The objective of this project is to examine the impact that common installation practices and age-induced equipment degradation may have on the installed performance of natural gas furnaces, as measured by steady-state efficiency and AFUE. PARR identified twelve furnaces of various ages and efficiencies that were operating in residential homes in the Des Moines Iowa metropolitan area and worked with a local HVAC contractor to retrieve them and test them for steady-state efficiency and AFUE in the lab. Prior to removal, system airflow, static pressure, equipment temperature rise, and flue loss measurements were recorded for each furnace. After removal from the field the furnaces were transported to the Gas Technology Institute (GTI) laboratory, where PARR conducted steady-state efficiency and AFUE testing. The test results show that steady-state efficiency in the field was 6.4% lower than that measured for the same furnaces under standard conditions in the lab, which included tuning the furnace input and air flow rate. Comparing AFUE measured under ASHRAE standard conditions with the label value shows no reduction in efficiency for the furnaces in this study over their 15 to 24 years of operation when tuned to standard conditions. Further analysis of the data showed no significant correlation between efficiency change and the age or the rated efficiency of the furnace.

Epidemiologic investigation of health effects in Air Force personnel following exposure to herbicides: Extract reproductive outcomes. Executive summary, introduction, and conclusions. Interim report, 1985-1992  

SciTech Connect

The Air Force is conducting a 20-year prospective study of veterans of Operation Ranch Hand, the unit responsible for aerial spraying of herbicides in Vietnam from 1962 to 1971. A comparison group of Air Force veterans who served in Southeast Asia (SEA) during the same period who were not occupationally exposed to herbicides was selected. The study, called the Air Force Health Study (AFHS), is in its tenth year and is designed to determine whether exposure to the herbicides or their contaminant, 2,3,37,8-tetrachlorodibenzo-p-dioxin (dioxin), has adversely affected the health, survival or reproductive outcomes of Ranch Hands. This report summarizes the findings of an investigation of reproductive outcomes of the 791 Ranch Hands and 942 Comparisons for whom a dioxin level had been determined by August, 1991. These men have fathered 5,489 pregnancies including 4,514 live births. These men are a subset of all Ranch Hands (n=1,098) and Comparisons (n=1,549) who have fathered 8,263 pregnancies and 6,792 live births. All data in this report have been verified by review of birth certificates, newborn clinic records, health records and death certificates. The birth defect status of each child was verified through the age of 18.

Install Waste Heat Recovery Systems for Fuel-Fired Furnaces (English/Chinese) (Fact Sheet)  

SciTech Connect

Chinese translation of ITP fact sheet about installing Waste Heat Recovery Systems for Fuel-Fired Furnaces. For most fuel-fired heating equipment, a large amount of the heat supplied is wasted as exhaust or flue gases. In furnaces, air and fuel are mixed and burned to generate heat, some of which is transferred to the heating device and its load. When the heat transfer reaches its practical limit, the spent combustion gases are removed from the furnace via a flue or stack. At this point, these gases still hold considerable thermal energy. In many systems, this is the greatest single heat loss. The energy efficiency can often be increased by using waste heat gas recovery systems to capture and use some of the energy in the flue gas. For natural gas-based systems, the amount of heat contained in the flue gases as a percentage of the heat input in a heating system can be estimated by using Figure 1. Exhaust gas loss or waste heat depends on flue gas temperature and its mass flow, or in practical terms, excess air resulting from combustion air supply and air leakage into the furnace. The excess air can be estimated by measuring oxygen percentage in the flue gases.

The public health assessment addendum addresses the two public health issues identified at Griffiss Air Force Base by the Agency for Toxic Substances and Disease Registry (ATSDR): (1) exposures to contaminated fish from Three Mile and Six Mile Creeks, and (2) past exposures to contaminated groundwater through private wells off base. Frequent consumption of contaminated fish from Three Mile and Six Mile Creeks could pose a health problem. However, if NYSDOH fish consumption guidelines are followed, fish consumption should not present a public health hazard. ATSDR cannot evaluate exposures to contaminated groundwater through private well use prior to 1982 because there are no sampling data.

Systems engineering approach to environmental risk management: A case study of depleted uranium at test area C-64, Eglin Air Force Base, Florida. Master`s thesis  

SciTech Connect

Environmental restoration is an area of concern in an environmentally conscious world. Much effort is required to clean up the environment and promote environmentally sound methods for managing current land use. In light of the public consciousness with the latter topic, the United States Air Force must also take an active role in addressing these environmental issues with respect to current and future USAF base land use. This thesis uses the systems engineering technique to assess human health risks and to evaluate risk management options with respect to depleted uranium contamination in the sampled region of Test Area (TA) C-64 at Eglin Air Force Base (AFB). The research combines the disciplines of environmental data collection, DU soil concentration distribution modeling, ground water modeling, particle resuspension modeling, exposure assessment, health hazard assessment, and uncertainty analysis to characterize the test area. These disciplines are required to quantify current and future health risks, as well as to recommend cost effective ways to increase confidence in health risk assessment and remediation options.

Coal-fired furnace for testing of thermionic converters. Topical report  

SciTech Connect

The development of thermionic converter technology has progressed to make near-term applications interesting. One of these applications is the thermionic topping of a pulverized coal-fired central station powerplant. Up to now, thermionic converters have been flame tested using natural gas as fuel. A new test furnace is required for evaluation of thermionic converters in a coal-fired environment. The design and costs of a facility which adapts a coal-fired furnace built by Foster Wheeler Development Corporation (FWDC) for thermionic converter testing are discussed. Such a facility would be exempt from air pollution regulations because of its low firing rate.

Combustion process in a biomass grate fired industry furnace: a CFD study  

Science Journals Connector (OSTI)

This paper presents a CFD investigation of the combustion process in a 50 MW grate fired furnace. The CFD results were compared with available experimental data at the furnace outlet to validate the models for the volatile oxidation and NOx formation. The models were then used to predict the effect of an 'ECO' tube system on NOx emissions. It was shown that with an improved flow structure and air distribution, 30% NOx reduction can be obtained. CFD results revealed the impact of load and fuel moisture on the flow structure, the temperature distribution and the flow residence time.

An aerial radiological survey of the Kennedy Space Center and Cape Canaveral Air Force Station and surrounding area, Titusville, Florida: Date of survey: October 1985  

SciTech Connect

An aerial radiological survey of the entire Kennedy Space Center (KSC) and Cape Canaveral Air Force Station (CCAFS) was performed during the period 9 through 23 October 1985. This survey was conducted in three parts. First, a low resolution, low sensitivity background survey was performed that encompassed the entire KSC and CCAFS area. Next, two smaller, high resolution, high sensitivity surveys were conducted: the first focused on Launch Complexes 39A and 39B, and the second on the Shuttle Landing Facility. The areas encompassed by the surveys were 200, 5.5, and 8.5 square miles (500, 14, and 22 sq km), respectively. The purpose of these surveys was to provide information useful for an emergency response to a radiological accident. Results of the background survey are presented as isoradiation contour maps of both total exposure rate and man-made gross count superimposed on a mosaic of recent aerial photographs. Results of the two small, detailed surveys are also presented as an isoradiation contour map of exposure rate on the aerial photograph base. These data were evaluated to establish sensitivity limits for mapping the presence of plutonium-238. Natural background exposure rates at the Kennedy Space Center and Cape Canaveral Air Force Station are very low, generally ranging from 4 to 6.5 microroentgens per hour (..mu..R/h) and less than 4 ..mu..R/h in wet areas. However, exposure rates in developed areas were observed to be higher due to the importation of construction materials not characteristic of the area. 8 refs., 3 figs., 4 tabs.

Coal combustion under conditions of blast furnace injection; [Quarterly] technical report, September 1--November 30, 1993  

SciTech Connect

A potentially new use for Illinois coal is its use as a fuel injected into a blast furnace to produce molten iron as the first step in steel production. Because of its increasing cost and decreasing availability, metallurgical coke is now being replaced by coal injected at the tuyere area of the furnace where the blast air enters. The purpose of this study is to evaluate the combustion of coal during the blast furnace injection process and to delineate the optimum properties of the feed coal. This investigation is significant to the use of Illinois coal in that the limited research to date suggests that coals of low fluidity and moderate to high sulfur and chlorine contents are suitable feedstocks for blast furnace injection. This study is unique in that it will be the first North American effort to directly determine the nature of the combustion of coal injected into a blast furnace. This proposal is a follow-up to one funded for the 1992--1993 period. It is intended to complete the study already underway with the Armco Inc. steel company and to initiate a new cooperative study along somewhat similar lines with the Inland Steel Company. The results of this study will lead to the development of a testing and evaluation protocol that will give a unique and much needed understanding of the behavior of coal in the injection process and prove the potential of Illinois coals f or such use.

US Air Force installation restoration program: Remedial investigation of former herbicide storage site at Johnston Island, Pacific Ocean  

SciTech Connect

This report represents a synthesis and reformatting of six primary documents and other related materials on soils, ocean sediments, air, and biota investigations conducted at Johnston Island (JI), Pacific Ocean, to characterize contamination resulting from storage of 1.37 million gallons of Herbicide Orange (HO) from 1972 through 1977. The individual study components comprise the Remedial Investigation (RI) of the former HO storage site at JI. This report describes the procedures, results, and conclusions of the sampling and analysis programs conducted at JI. Samples of site soils, ocean sediments, airborne particulates, dust, sweepings, and aquatic organisms were collected and analyzed for HO-derived 2,4-dichlorophenoxyacetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), and 2,3,7,8- tetrachlorodibenzo-p-dioxin (TCDD). Environmental media other than soils at the storage facility itself were found to be free of contamination or to contain very low contaminant concentrations. No contamination was found in ocean sediments, indicating possible dispersion of contaminants due to erosion. A few of the biological specimens collected were found to contain TCDD levels below the guidelines of 25 to 50 parts per trillion established by the US Food and Drug Administration; TCDD in all other biota samples was nondetectable. Analysis of samples of airborne particulates and of soils, dust, and sweepings from high-use and residential areas outside the boundaries of the former storage site indicated that there is little or no concern of adverse impacts from airborne transport and deposition of TCDD.

Coal combustion under conditions of blast furnace injection. [Quarterly] technical report, 1 March 1993--31 May 1993  

SciTech Connect

A potentially new use for Illinois coal is its use as a fuel injected into a blast furnace to produce molten iron as the first step in steel production. Because of its increasing cost and decreasing availability, metallurgical coke is now being replaced by coal injected at the tuyere area of the furnace where the blast air enters. The purpose of this study is to evaluate the combustion of coal during the blast furnace injection process and to delineate the optimum properties of the feed coal. The basic program is designed to determine the reactivity of both coal and its derived char under blast furnace conditions and to compare the results to similar properties of blast furnace coke. The results of the first two experiments in which coal char pyrolyzed in nitrogen at 1000{degrees}C in an EPR were reacted isothermally in air at 1000{degrees}C and 1200{degrees}C. The reactivity values of the same char in these two experiments were different by an order of magnitude. The char reactivity at 1000{degrees}C was 9.7 {times} 10{sup {minus}4} grams per minute while the reactivity. of the char at 1200{degrees}C was 1.6 {times} 10{sup {minus}3} grams per minute. These results suggest that the temperature of the blast air in the tuyere may be critical in achieving complete carbon burnout.

Graphite electrode DC arc furnace. Innovative technology summary report  

SciTech Connect

The Graphite Electrode DC Arc Furnace (DC Arc) is a high-temperature thermal process, which has been adapted from a commercial technology, for the treatment of mixed waste. A DC Arc Furnace heats waste to a temperature such that the waste is converted into a molten form that cools into a stable glassy and/or crystalline waste form. Hazardous organics are destroyed through combustion or pyrolysis during the process and the majority of the hazardous metals and radioactive components are incorporated in the molten phase. The DC Arc Furnace chamber temperature is approximately 593--704 C and melt temperatures are as high as 1,500 C. The DC Arc system has an air pollution control system (APCS) to remove particulate and volatiles from the offgas. The advantage of the DC Arc is that it is a single, high-temperature thermal process that minimizes the need for multiple treatment systems and for extensive sorting/segregating of large volumes of waste. The DC Arc has the potential to treat a wide range of wastes, minimize the need for sorting, reduce the final waste volumes, produce a leach resistant waste form, and destroy organic contaminants. Although the DC arc plasma furnace exhibits great promise for treating the types of mixed waste that are commonly present at many DOE sites, several data and technology deficiencies were identified by the Mixed Waste Focus Area (MWFA) regarding this thermal waste processing technique. The technology deficiencies that have been addressed by the current studies include: establishing the partitioning behavior of radionuclides, surrogates, and hazardous metals among the product streams (metal, slag, and offgas) as a function of operating parameters, including melt temperature, plenum atmosphere, organic loading, chloride concentration, and particle size; demonstrating the efficacy of waste product removal systems for slag and metal phases; determining component durability through test runs of extended duration, evaluating the effect of feed composition variations on process operating conditions and slag product performance; and collecting mass balance and operating data to support equipment and instrument design.

Cogeneration from glass furnace waste heat recovery  

SciTech Connect

In glass manufacturing 70% of the total energy utilized is consumed in the melting process. Three basic furnaces are in use: regenerative, recuperative, and direct fired design. The present paper focuses on secondary heat recovery from regenerative furnaces. A diagram of a typical regenerative furnace is given. Three recovery bottoming cycles were evaluated as part of a comparative systems analysis: steam Rankine Cycle (SRC), Organic Rankine Cycle (ORC), and pressurized Brayton cycle. Each cycle is defined and schematicized. The net power capabilities of the three different systems are summarized. Cost comparisons and payback period comparisons are made. Organic Rankine cycle provides the best opportunity for cogeneration for all the flue gas mass flow rates considered. With high temperatures, the Brayton cycle has the shortest payback period potential, but site-specific economics need to be considered.

RCRA closure of an explosive ordnance disposal (EOD) range, Wright-Patterson Air Force Base, Ohio: Circumstances leading to a risk based approach  

SciTech Connect

After approximately 40 years of operation of an Explosive Ordnance Disposal (EOD) Range at Wright-Patterson Air Force Base (WPAFB) near Dayton, Ohio, operations were suspended in late 1990 by the Ohio Environmental Protection Agency (OEPA). The closure of several notice of violations and reopening of the EOD Range were the initial objectives, but in 1995 a formal commitment for RCRA closure was made. The EOD Range, used for disposal of ordnance via open burning and open detonation, is a fenced 5 acre site and is located in a 100 year flood plain. Investigations performed in 1991 through 1994 to fully characterize the site indicated the presence of heavy metals and petroleum contamination in soils. Of particular concern were elevated levels of arsenic and lead. Localized remediations were attempted in 1993, but because of continued disagreement on cleanup levels with OEPA, these remediations were unsuccessful. Strict interpretation of OEPA RCRA closure guidance would have required the removal of soil from the entire five acre EOD Range to a depth of 4--5 feet, at a cost of approximately $6,000,000. However, in early 1995 a partnering session held with OEPA led to an improved regulatory relationship with OEPA. This improved relationship, along with new information compiled on industrial background concentrations of heavy metals at RCRA sites in Ohio, and emerging OEPA guidance on broader risk ranges for closure may prove to be key in reducing closure requirements. A draft Closure Plan has been submitted to OEPA which proposes a risk-based approach for closure. The plan is currently under review by OEPA. If approved, the AF could realize a substantial savings of greater than $5,000,000. This paper details the sequence of events in performing a RCRA closure at the EOD range, including the site conditions and field activities, and the evolution of closure requirements.

Through a partnership with a federal site, the utility serving the site, a manufacturer of an energy-related technology, and other organizations associated with these interests, DOE can evaluate a new technology. The results of the program give federal agency decision makers more hands-on information with which to validate a decision to utilize a new technology in their facilities. The partnership of these interests is secured through a cooperative research and development agreement (CRADA), in this case between Lockheed Martin Energy Research Corporation, the manager of the Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee, and ThermShield International, Ltd., the manufacturer of the technology. This is the first volume of a two-volume report that describes the effects of radiation control coatings installed on federal buildings at Tyndall Air Force Base (AFB) in Florida by ThermShield International. ORNL`s Buildings Technology Center (BTC) was assigned the responsibility for gathering, analyzing, and reporting on the data to describe the effects of the coatings. This volume describes the monitoring plan and its implementation, the results of pre-coating monitoring, the coating installation, results from fresh coatings compared to pre-coating results, and a plan to decommission the monitoring equipment. By including results from roofs at Tyndall AFB and from an outdoor test facility at the BTC, the data cover the range from poorly insulated to well-insulated roofs and two kinds of radiation control coatings on various roof membranes.

Investigation of lignite and firewood co-combustion in a furnace for tobacco curing application  

SciTech Connect

Co-combustion of lignite and firewood was investigated for an application in tobacco curing industry in Northern Thailand. Extensive experiments have been carried out in a newly developed furnace suitable for small curing unit, in place of locally made furnace. The aim of this investigation is to evaluate the performance of the combustion chamber in the required thermal output range for tobacco curing and to examine the influence of fuel feed rate, fuel mixture ratio and air staging on the combustion and emission characteristics of the furnace during steady state operation. Their effects are characterized in terms of the observed variations of temperature distributions, emissions of CO, SO{sub 2}, CO{sub 2}, O{sub 2} and combustion efficiency. Co-firing of firewood and lignite has been found to exhibit acceptable temperature distribution, high combustion efficiency and low emissions over a wide thermal output span. Stable operation at low (50 kW) and high (150 kW) thermal output was achieved with average CO and SO{sub 2} content in flue gas typically below 1400 and 100 ppm, respectively. Under the conditions considered, it was showed that the fuel feed rate had greater influence on combustion and emissions than firewood and lignite mixture ratio and air staging.

Method of operating a centrifugal plasma arc furnace  

DOE Patents (OSTI)

A centrifugal plasma arc furnace is used to vitrify contaminated soils and other waste materials. An assessment of the characteristics of the waste is performed prior to introducing the waste into the furnace. Based on the assessment, a predetermined amount of iron is added to each batch of waste. The waste is melted in an oxidizing atmosphere into a slag. The added iron is oxidized into Fe{sub 3}O{sub 4}. Time of exposure to oxygen is controlled so that the iron does not oxidize into Fe{sub 2}O{sub 3}. Slag in the furnace remains relatively non-viscous and consequently it pours out of the furnace readily. Cooled and solidified slag produced by the furnace is very resistant to groundwater leaching. The slag can be safely buried in the earth without fear of contaminating groundwater. 3 figs.

Experimental characterization of an industrial pulverized coal-fired furnace under deep staging conditions  

SciTech Connect

Measurements have been performed in a 300 MWe, front-wall-fired, pulverized-coal, utility boiler. This boiler was retrofitted with boosted over fire air injectors that allowed the operation of the furnace under deeper staging conditions. New data are reported for local mean gas species concentration of O{sub 2}, CO, CO{sub 2}, NOx, gas temperatures and char burnout measured at several ports in the boiler including those in the main combustion and staged air regions. Comparisons of the present data with our previous measurements in this boiler, prior to the retrofitting with the new over fire system, show lower O{sub 2} and higher CO concentrations for the new situation as a consequence of the lower stoichiometry in the main combustion zone associated with the present boiler operating condition. Consistently, the measured mean NOx concentrations in the main combustion zone are now lower than those obtained previously, yielding emissions below 500 mg/Nm{sup 3}at 6% O{sub 2}. Finally, the measured values of particle burnout at the furnace exit are acceptable being those measured in the main combustion zone comparable with those obtained with the conventional over fire system.

Variable firing rate power burner for high efficiency gas furnaces. Final report  

SciTech Connect

One method for increasing the efficiency of residential furnaces and boilers is to retrofit a burner capable of firing rate (FR) modulation. While maximum FR is still attainable, the average FR is significantly lower, resulting in more effective heat exchanger performance. Equally important is the capability for continuous firing at a very low rate (simmering) which eliminates off-cycle loss, a heavy contributor to inefficiency. Additional performance can be gained by reducing the excess air required by a burner. Based on its previous experience, Foster-Miller Associates, Inc. has designed and tested a low excess air (about 15%) variable firing rate (VFR) burner. The theory of operation and the construction of the test burner are described. Test results are given along with a conclusion/recommendation. A Phase II plan is outlined which suggests methods and steps for fabrication and field testing of a number of prototype units.

ALTERNATE REDUCTANT COLD CAP EVALUATION FURNACE PHASE I TESTING  

SciTech Connect

Savannah River Remediation (SRR) conducted a Systems Engineering Evaluation (SEE) to determine the optimum alternate reductant flowsheet for the Defense Waste Processing Facility (DWPF). Specifically, two proposed flowsheets (nitricformicglycolic and nitricformicsugar) were evaluated based upon results from preliminary testing. Comparison of the two flowsheets among evaluation criteria indicated a preference towards the nitricformicglycolic flowsheet. Further evaluation of this flowsheet eliminated the formic acid1, and as a result, the nitricglycolic flowsheet was recommended for further testing. Based on the development of a roadmap for the nitricglycolic acid flowsheet, Waste Solidification Engineering (WS-E) issued a Technical Task Request (TTR) to address flammability issues that may impact the implementation of this flowsheet. Melter testing was requested in order to define the DWPF flammability envelope for the nitric glycolic acid flowsheet. The Savannah River National Laboratory (SRNL) Cold Cap Evaluation Furnace (CEF), a 1/12th scale DWPF melter, was selected by the SRR Alternate Reductant project team as the melter platform for this testing. The overall scope was divided into the following sub-tasks as discussed in the Task Technical and Quality Assurance Plan (TTQAP): ? Phase I - A nitricformic acid flowsheet melter test (unbubbled) to baseline the Cold Cap Evaluation Furnace (CEF) cold cap and vapor space data to the benchmark melter flammability models ? Phase II - A nitricglycolic acid flowsheet melter test (unbubbled and bubbled) to: o Define new cold cap reactions and global kinetic parameters for the melter flammability models o Quantify off-gas surging potential of the feed o Characterize off-gas condensate for complete organic and inorganic carbon species Prior to startup, a number of improvements and modifications were made to the CEF, including addition of cameras, vessel support temperature measurement, and a heating element near the pour tube. After charging the CEF with cullet from a previous Sludge Batch 6 (SB6) run, the melter was slurry-fed with SB6-Frit 418 melter feed at 36% waste loading and was operated continuously for 6 days. Process data was collected throughout testing and included melter operation variables and off-gas chemistry. In order to satisfy the objective of Phase I testing, vapor space steady testing in the range of ~300C-700C was conducted without argon bubbling to baseline the melter data to the existing DWPF melter flammability model. Adjustments to heater outputs, air flows and feed rate were necessary in order to achieve the vapor space temperatures in this range. The results of the Phase I testing demonstrated that the CEF is capable of operating under the low vapor space temperatures A melter pressure of -5 inches of water was not sustained throughout the run, but the melter did remain slightly negative even with the maximum air flows required for the lowest temperature conditions were used. The auxiliary pour tube heater improved the pouring behavior at all test conditions, including reduced feed rates required for the low vapor space testing. Argon bubbling can be used to promote mixing and increase feed rate at multiple conditions. Improvements due to bubbling have been determined previously; however, the addition of the cameras to the CEF allows for visual observation during a range of bubbling configurations. The off-gas analysis system proved to be robust and capable of operating for long durations. The total operational hours on the melter vessel are approximately 385 hours. Dimensional measurements taken prior to Phase I testing and support block temperatures recorded during Phase I testing are available if an extension of service life beyond 1250 hours is desired in the future.

Voltage flicker prediction for two simultaneously operated ac arc furnaces  

SciTech Connect

An EMTP-based arc furnace model was developed for evaluation of flicker concerns associated with supplying a large integrated steel mill as they go from one to two furnace operation and as system changes are implemented that will affect the short circuit capacity at the 230 kV power supply substation. The model includes a dynamic arc representation which is designed to be characteristic of the initial portions of the melt cycle when the arc characteristics are the most variable (worst flicker conditions). The flicker calculations are verified using previous measurements with one furnace operation. Flicker simulations were then performed to evaluate a variety of different possible system strengths with both one and two furnaces in operation. The primary flicker measure used for this study is the unweighted rms value of the fluctuation envelope, expressed as a percentage of the rms line-to-ground voltage magnitude.

Independent Validation and Verification of Process Design and Optimization Technology Diagnostic and Control of Natural Gas Fired Furnaces via Flame Image Analysis Technology  

SciTech Connect

The United States Department of Energy, Industrial Technologies Program has invested in emerging Process Design and Optimizations Technologies (PDOT) to encourage the development of new initiatives that might result in energy savings in industrial processes. Gas fired furnaces present a harsh environment, often making accurate determination of correct air/fuel ratios a challenge. Operation with the correct air/fuel ratio and especially with balanced burners in multi-burner combustion equipment can result in improved system efficiency, yielding lower operating costs and reduced emissions. Flame Image Analysis offers a way to improve individual burner performance by identifying and correcting fuel-rich burners. The anticipated benefit of this technology is improved furnace thermal efficiency, and lower NOx emissions. Independent validation and verification (V&V) testing of the FIA technology was performed at Missouri Forge, Inc., in Doniphan, Missouri by Environ International Corporation (V&V contractor) and Enterprise Energy and Research (EE&R), the developer of the technology. The test site was selected by the technology developer and accepted by Environ after a meeting held at Missouri Forge. As stated in the solicitation for the V&V contractor, 'The objective of this activity is to provide independent verification and validation of the performance of this new technology when demonstrated in industrial applications. A primary goal for the V&V process will be to independently evaluate if this technology, when demonstrated in an industrial application, can be utilized to save a significant amount of the operating energy cost. The Seller will also independently evaluate the other benefits of the demonstrated technology that were previously identified by the developer, including those related to product quality, productivity, environmental impact, etc'. A test plan was provided by the technology developer and is included as an appendix to the summary report submitted by Environ (Appendix A). That plan required the V&V contractor to: (1) Establish the as-found furnace operating conditions; (2) Tune the furnace using currently available technology to establish baseline conditions; (3) Tune the furnace using the FIA technology; and (4) Document the improved performance that resulted from application of the FIA technology. It is important to note that the testing was not designed to be a competition or comparison between two different methodologies that could be used for furnace tuning. Rather, the intent was to quantify improvements in furnace performance that could not be achieved with existing technology. Therefore, the measure of success is improvement beyond the furnace efficiency obtainable using existing furnace optimization methods rather than improvement from the as found condition.

Geothermal Energy Development in the Eastern United States: Technical assistance report No. 6 geothermal space heating and airconditioning -- McGuire Air Force Base, New Jersey  

SciTech Connect

A method of utilizing the geothermal (66 F) water resource for space heating and cooling of 200 of the 1452 housing units at McGuire AFB is suggested. Using projections of future costs of gas, coal and electricity made by DOD and by industry (Westinghouse), the relative costs of the geothermal-water-plus-heat-pump system and the otherwise-planned central gas heating (to be converted to coal in 1984) and air-conditioning (using individual electric units) system are compared. For heating with the geothermal/heat-pump system, an outlet temperature of 130 F is selected, requiring a longer running time than the conventional system (at 180 F) but permitting a COP (coefficient of performance) of the heat pump of about 3.4. For cooling (obtained in this study by changing directions of water flow, not refrigerant cycles), the change in temperature is less, and a COP near 4.5 is obtained. The cost of cooling in the summer months would be significantly less than the cost of using individual electric air-conditioners. Thus, by using nonreversible heat pumps, geothermal water is used to heat and to cool a section of the housing compound, minimizing operating expenditures. It is estimated that, to drill 1000 ft deep production and reinjection wells and to install ten heat pumps, heat exchangers and piping, would require a capital outlay of $643 K. This cost would replace the capital cost of purchasing and installing 200 air-conditioning units and 14% of the cost of the future coal-fired central heating system (which would otherwise serve all 1452 housing units at McGuire). The net additional capital outlay would be $299 K, which could be amortized in 10 years by the lower operating cost of the geothermal system if electricity and coal prices escalate as industry suggests. If the coal and electricity costs rise at the more modest rates that DOD projects, the capital costs would be amortized in a 15 year period.

Fireside carburization of stainless steel furnace tubes  

SciTech Connect

Most heavy Venezuelan crudes are recognized for having a high total acid number (TAN) that is usually associated with a high tendency to produce naphthenic acid corrosion. To resist this type of corrosion in vacuum heaters, 9Cr-1Mo steel and stainless steels containing molybdenum are usually recommended. In 1993 the original 5Cr-1/2Mo roof tubes of the furnace in a vacuum unit were replaced by stainless steel 316Ti to minimize tube replacement and increase heater reliability. Unexpectedly, some of the new tubes failed after only three years of service, and just one year after undergoing the last turnaround inspection. The damage occurred in the form of deep holes and perforations, starting from the outside tube surface on the fireside. Coke build-up occurred due to severe operating conditions, overheating the tubes on the fireside, above 675 C (1250 F). Metallographic and Scanning Electron Microscopic (SEM) examination revealed internal and external carburization of the material due to the presence of coke and combustion ashes, respectively. The increase in the skin metal temperature facilitated the diffusion of carbon from these carbon-rich deposits into the low carbon content material (0.023 O/O).Depletion of chromium at the grain boundaries due to the massive formation of chromium carbides, resulted in a severe intergranular corrosion attack by molten salts rich in vanadium and sulfur due to asphalt burning. Normal operating practice demands the use of steam for the heater tubes to control coke build-up. This practice had been first reduced and then eliminated, during the past two years prior to the failure, because of economic incentives. This paper describes the root cause analysis conducted to account for these premature tube failures.

Waste Heat Recovery from High Temperature Off-Gases from Electric Arc Furnace  

SciTech Connect

This article presents a study and review of available waste heat in high temperature Electric Arc Furnace (EAF) off gases and heat recovery techniques/methods from these gases. It gives details of the quality and quantity of the sensible and chemical waste heat in typical EAF off gases, energy savings potential by recovering part of this heat, a comprehensive review of currently used waste heat recovery methods and potential for use of advanced designs to achieve a much higher level of heat recovery including scrap preheating, steam production and electric power generation. Based on our preliminary analysis, currently, for all electric arc furnaces used in the US steel industry, the energy savings potential is equivalent to approximately 31 trillion Btu per year or 32.7 peta Joules per year (approximately $182 million US dollars/year). This article describes the EAF off-gas enthalpy model developed at Oak Ridge National Laboratory (ORNL) to calculate available and recoverable heat energy for a given stream of exhaust gases coming out of one or multiple EAF furnaces. This Excel based model calculates sensible and chemical enthalpy of the EAF off-gases during tap to tap time accounting for variation in quantity and quality of off gases. The model can be used to estimate energy saved through scrap preheating and other possible uses such as steam generation and electric power generation using off gas waste heat. This article includes a review of the historical development of existing waste heat recovery methods, their operations, and advantages/limitations of these methods. This paper also describes a program to develop and test advanced concepts for scrap preheating, steam production and electricity generation through use of waste heat recovery from the chemical and sensible heat contained in the EAF off gases with addition of minimum amount of dilution or cooling air upstream of pollution control equipment such as bag houses.

Energy audit of three energy-conserving devices in a steel-industry demonstration program. Task I. Hague forge furnaces. Final report  

SciTech Connect

A program to demonstrate to industry the benefits of installing particular types of energy-conserving devices and equipment was carried out. One of these types of equipment and the results obtained under production conditions in commercial plants are described. The equipment under consideration includes improved forge furnaces and associated heat-recovery components. They are used to heat steel to about 2300 F prior to hot forging. The energy-conserving devices include improved insulation, automatic air-fuel ratio control, and a ceramic recuperator that recovers heat from hot combustion gases and delivers preheated air to high-temperature recirculating burners. Twelve Hague furnaces and retrofit packages were purchased and installed by eleven host forge shops that agree to furnish performance data for the purpose of demonstrating the energy and economic savings that can be achieved in comparison with existing equipment. Fuel savings were reported by comparing the specific energy consumption (Btu's per pound of steel heated) for each Hague furnace with that of a comparison furnace. Economic comparisons were made using payback period based on annual after-tax cash flow. Payback periods for the Hague equipment varied from less than two years to five years or more. In several cases, payback times were high only because the units were operated at a small fraction of their available capacity.

A new compact fixed-point blackbody furnace  

SciTech Connect

More and more NMIs are realizing their primary scale themselves with fixed-point blackbodies as their reference standard. However, commercially available fixed-point blackbody furnaces of sufficient quality are not always easy to obtain. CHINO Corp. and NMIJ, AIST jointly developed a new compact fixed-point blackbody furnace. The new furnace has such features as 1) improved temperature uniformity when compared to previous products, enabling better plateau quality, 2) adoption of the hybrid fixed-point cell structure with internal insulation to improve robustness and thereby to extend lifetime, 3) easily ejectable and replaceable heater unit and fixed-point cell design, leading to reduced maintenance cost, 4) interchangeability among multiple fixed points from In to Cu points. The replaceable cell feature facilitates long term maintenance of the scale through management of a group of fixed-point cells of the same type. The compact furnace is easily transportable and therefore can also function as a traveling standard for disseminating the radiation temperature scale, and for maintaining the scale at the secondary level and industrial calibration laboratories. It is expected that the furnace will play a key role of the traveling standard in the anticipated APMP supplementary comparison of the radiation thermometry scale.

Semicoke production and quality at Chinese vertical SJ furnaces  

SciTech Connect

In Russia there has been little interest on the thermal processing of non-sintering coal. However it may be used to obtain many special types of coke and semicoke that are necessary for processes other than blast furnace smelting and employing small metallurgical coke fractions that do not meet the relevant quality requirements. China has recently made great progress in developing the thermal processing of coal (mainly energy coal) to obtain a highly effective product, semicoke, primarily used in metallurgy and adsorption process. The article considers the operation of a Chinese semicoking plant equipped with vertical SJ furnaces. The plant is in the Shenmu district of Shanxi province (Inner Mongolia). The enterprise includes two furnaces of total output of about 100,000 t/yr of semicoke.

ALTERNATE REDUCTANT COLD CAP EVALUATION FURNACE PHASE II TESTING  

SciTech Connect

Savannah River Remediation (SRR) conducted a Systems Engineering Evaluation (SEE) to determine the optimum alternate reductant flowsheet for the Defense Waste Processing Facility (DWPF). Specifically, two proposed flowsheets (nitricformicglycolic and nitricformicsugar) were evaluated based upon results from preliminary testing. Comparison of the two flowsheets among evaluation criteria indicated a preference towards the nitricformicglycolic flowsheet. Further research and development of this flowsheet eliminated the formic acid, and as a result, the nitricglycolic flowsheet was recommended for further testing. Based on the development of a roadmap for the nitricglycolic acid flowsheet, Waste Solidification Engineering (WS-E) issued a Technical Task Request (TTR) to address flammability issues that may impact the implementation of this flowsheet. Melter testing was requested in order to define the DWPF flammability envelope for the nitric-glycolic acid flowsheet. The Savannah River National Laboratory (SRNL) Cold Cap Evaluation Furnace (CEF), a 1/12th scale DWPF melter, was selected by the SRR Alternate Reductant project team as the melter platform for this testing. The overall scope was divided into the following sub-tasks as discussed in the Task Technical and Quality Assurance Plan (TTQAP): ? Phase I - A nitricformic acid flowsheet melter test (unbubbled) to baseline the CEF cold cap and vapor space data to the benchmark melter flammability models; ? Phase II - A nitricglycolic acid flowsheet melter test (unbubbled and bubbled) to: o Define new cold cap reactions and global kinetic parameters in support of the melter flammability model development; o Quantify off-gas surging potential of the feed; o Characterize off-gas condensate for complete organic and inorganic carbon species. After charging the CEF with cullet from Phase I CEF testing, the melter was slurry-fed with glycolic flowsheet based SB6-Frit 418 melter feed at 36% waste loading and was operated continuously for 25 days. Process data was collected throughout testing and included melter operation parameters and off-gas chemistry. In order to generate off-gas data in support of the flammability model development for the nitric-glycolic flowsheet, vapor space steady state testing in the range of ~300-750C was conducted under the following conditions, (i) 100% (nominal and excess antifoam levels) and 125% stoichiometry feed and (ii) with and without argon bubbling. Adjustments to feed rate, heater outputs and purge air flow were necessary in order to achieve vapor space temperatures in this range. Surge testing was also completed under nominal conditions for four days with argon bubbling and one day without argon bubbling.

Coke mineral transformations in the experimental blast furnace  

SciTech Connect

Blast furnace efficiency may be improved by optimizing coke reactivity. Some but not all forms of mineral matter in the coke modify its reactivity, but changes in mineral matter that occur within coke while in the blast furnace have not been fully quantified. To determine changes in mineral matter forms in the blast furnace, coke samples from a dissection study in the LKAB experimental blast furnace (EBF) were characterized using SEM/EDS analysis, EPMA (microprobe), and low-temperature ashing/quantitative XRD analysis. Variations in alkali concentration, particularly potassium, dominated the compositional changes. At high concentrations of potassium, the mineral matter was largely potassium-bearing but even more potassium was diffused throughout the coke and not associated with mineral matter. There was little difference in potassium concentration between the core and surface of the coke pieces, suggesting that potassium diffused rapidly through the whole coke. Iron, calcium, silicon, and aluminum concentrations were relatively constant in comparison, although the mineralogy of all elements changed significantly with changing temperature. 23 refs., 20 figs., 9 tabs.

Experimenting with concentrated sunlight using the DLR solar furnace  

SciTech Connect

The high flux solar furnace that is operated by the Deutsche Forschungsanstalt fuer Luft- und Raumfahrt (DLR) at Cologne was inaugurated in June 1994 and we are now able to look back onto one year of successful operation. The solar furnace project was founded by the government of the State Northrhine Westfalia within the Study Group AG Solar. The optical design is a two-stage off-axis configuration which uses a flat 52 m{sup 2} heliostat and a concentrator composed of 147 spherical mirror facets. The heliostat redirects the solar light onto the concentrator which focuses the beam out of the optical axis of the system into the laboratory building. At high insolation levels (>800W/m{sup 2}) it is possible to collect a total power of 20 kW with peak flux densities of 4 MW/m{sup 2}. Sixteen different experiment campaigns were carried out during this first year of operation. The main research fields for these experiments were material science, component development and solar chemistry. The furnace also has its own research program leading to develop sophisticated measurement techniques like remote infrared temperature sensing and flux mapping. Another future goal to be realized within the next five years is the improvement of the performance of the furnace itself. 6 refs., 9 figs., 1 tab.

Exergy transfer analysis of an aluminum holding furnace  

Science Journals Connector (OSTI)

Abstract This study presents the unsteady exergy transfer analysis of an aluminum holding furnace with new heating resistance scheme. This holding system consists of four multilayer refractory walls and one resistance heating system which is responsible of maintaining the appropriate aluminum temperature and composition for further casting. The purpose of this analysis is to understand and identify heat losses and irreversibilities of the holding process of an aluminum furnace by means of the First and Second Law of Thermodynamics. In this study, bi-dimensional temperature and exergy fields during heat and exergy transfer processes are presented. The exergy balance is completely computed for this system, obtaining: exergy transfer, exergy variation rate, and destroyed exergy rate.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF)  

SciTech Connect

A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluate the economic and technical feasibility of the concept, and prepare an R D plan to develop the concept further. Foster Wheeler Development Corporation is leading a team ofcompanies involved in this effort. The system proposed to meet these goals is a combined-cycle system where air for a gas turbine is indirectly heated to approximately 1800[degrees]F in furnaces fired with cool-derived fuels and then directly heated in a natural-gas-fired combustor up to about 2400[degrees]F. The system is based on a pyrolyzing process that converts the coal into a low-Btu fuel gas and char. The fuelgas is a relatively clean fuel, and it is fired to heat tube surfaces that are susceptible to corrosion and problems from ash deposition. In particular, the high-temperature air heater tubes, which will need tobe a ceramic material, will be located in a separate furnace or region of a furnace that is exposed to combustion products from the low-Btu fuel gas only. A simplified process flow diagram is shown.

FURNACE INJECTION OF ALKALINE SORBENTS FOR SULFURIC ACID CONTROL  

SciTech Connect

This document summarizes progress on Cooperative Agreement DE-FC26-99FT40718, Furnace Injection of Alkaline Sorbents for Sulfuric Acid Control, during the time period April 1, 2001 through September 30, 2001. The objective of this project is to demonstrate the use of alkaline reagents injected into the furnace of coal-fired boilers as a means of controlling sulfuric acid emissions. The coincident removal of hydrochloric acid and hydrofluoric acid is also being determined, as is the removal of arsenic, a known poison for NO{sub x} selective catalytic reduction (SCR) catalysts. EPRI, the Tennessee Valley Authority (TVA), FirstEnergy Corporation, and the Dravo Lime Company are project co-funders. URS Corporation is the prime contractor. During the current period, American Electric Power (AEP) joined the project as an additional co-funder and as a provider of a host site for testing. This is the fourth reporting period for the subject Cooperative Agreement. During this period, two long-term sorbent injection tests were conducted, one on Unit 3 at FirstEnergy's Bruce Mansfield Plant (BMP) and one on Unit 1 at AEP's Gavin Station. These tests determined the effectiveness of injecting alkaline slurries into the upper furnace of the boiler as a means of controlling sulfuric acid emissions from these units. The alkaline slurries tested included commercially available magnesium hydroxide slurry (Gavin Station), and a byproduct magnesium hydroxide slurry (both Gavin Station and BMP). The tests showed that injecting either the commercial or the byproduct magnesium hydroxide slurry could achieve up to 70 to 75% sulfuric acid removal. At BMP, the overall removal was limited by the need to maintain acceptable electrostatic precipitator (ESP) particulate control performance. At Gavin Station, the overall sulfuric acid removal was limited because the furnace injected sorbent was less effective at removing SO{sub 3} formed across the SCR system installed on the unit for NO{sub x} control than at removing SO{sub 3} formed in the furnace. Balance of plant impacts, primarily on the ESP particulate control device, were also determined during both tests. These results are presented and discussed in this report.

Time and Temperature Test Results for PFP Thermal Stabilization Furnaces  

SciTech Connect

The national standard for plutonium storage acceptability (standard DOE-STD-3013-99, generally known as ''the 3013 standard'') has been revised to clarify the requirement for processes that will produce acceptable storage materials. The 3013 standard (Reference 1) now states that ''Oxides shall be stabilized by heating the material in an oxidizing atmosphere to a Material Temperature of at least 950 C (1742 F) for not less than 2 hours.'' The process currently in use for producing stable oxides for storage at the Plutonium Finishing Plant (PFP) heats a furnace atmosphere to 1000 C and holds it there for 2 hours. The temperature of the material being stabilized is not measured directly during this process. The Plutonium Process Support Laboratories (PPSL) were requested to demonstrate that the process currently in use at PFP is an acceptable method of producing stable plutonium dioxide consistently. A spare furnace identical to the production furnaces was set up and tested under varying conditions with non-radioactive surrogate materials. Reference 2 was issued to guide the testing program. The process currently in use at the PFP for stabilizing plutonium-bearing powders was shown to heat all the material in the furnace to at least 950 C for at least 2 hours. The current process will work for (1) relatively pure plutonium dioxide, (2) dioxide powders mixed with up to 20 weight percent magnesium oxide, and (3) dioxide powders with up to 11 weight percent magnesium oxide and 20 weight percent magnesium nitrate hexahydrate. Time and temperature data were also consistent with a successful demonstration for a mixture containing 10 weight percent each of sodium and potassium chloride; however, the molten chloride salts destroyed the thermocouples in the powder and temperature data were unavailable for part of that run. These results assume that the current operating limits of no more than 2500 grams per furnace charge and a powder height of no more than 1.5 inches remain in effect, although deeper powder beds (up to 2 inches) also yielded temperatures of greater than 950 C for longer than 2 hours.

This article examines the preparation of coke for blast-furnace smelting by a method that most fully meets the requirements of blast-furnace technology: screening of the -36 mm fraction, the separation of nut coke of the 15-36 mm fraction, and its charging into the furnace in a mixture with the iron-ore-bearing charge components. An analysis is made of trial use of coke of the Premium class on blast furnace No. 5 at the Enakievo Metallurgical Plant. Use of this coke makes it possible to reduce the consumption of skip coke by 3.2-4.1%.

Modeling energy consumption of residential furnaces and boilers in U.S. homes  

SciTech Connect

In 2001, DOE initiated a rulemaking process to consider whether to amend the existing energy efficiency standards for furnaces and boilers. A key factor in DOE's consideration of new standards is their cost-effectiveness to consumers. Determining cost-effectiveness requires an appropriate comparison of the additional first cost of energy efficiency design options with the savings in operating costs. This report describes calculation of equipment energy consumption (fuel and electricity) based on estimated conditions in a sample of homes that are representative of expected furnace and boiler installations. To represent actual houses with furnaces and boilers in the United States, we used a set of houses from the Residential Energy Consumption Survey of 1997 conducted by the Energy Information Administration. Our calculation methodology estimates the energy consumption of alternative (more-efficient) furnaces, if they were to be used in each house in place of the existing equipment. We developed the method of calculation described in this report for non-weatherized gas furnaces. We generalized the energy consumption calculation for this product class to the other furnace product classes. Fuel consumption calculations for boilers are similar to those for the other furnace product classes. The electricity calculations for boilers are simpler than for furnaces, because boilers do not provide thermal distribution for space cooling as furnaces often do.

Variation in coke properties within the blast-furnace shop  

SciTech Connect

In active production at OAO Magnitogorskii Metallurgicheskii Kombinat (MMK), samples of melt materials were taken during shutdown and during planned repairs at furnaces 1 and 8. In particular, coke was taken from the tuyere zone at different distances from the tuyere tip. The mass of the point samples was 2-15 kg, depending on the sampling zone. The material extracted from each zone underwent magnetic separation and screening by size class. The resulting coke sample was averaged out and divided into parts: one for determining the granulometric composition and mechanical strength; and the other for technical analysis and determination of the physicochemical properties of the coke.

Integrated emissions control system for residential CWS furnace. Annual status report number 1, 20 September 1989--30 September 1990  

SciTech Connect

One of the major obstacles to the successful development and commercialization of a coal-fired residential furnace is the need for a reliable, cost-effective emission control system. Tecogen Inc. is developing a novel, integrated emission control system to control NO{sub x}, SO{sub 2}, and particulate emissions. A reactor provides high sorbent particle residence time within the reactor to control SO{sub 2} emissions, while providing a means of extracting a substantial amount of the particulates present in the combustion gases. Final cleanup of any flyash exiting the reactor is completed with the use of high-efficiency bag filters. Tecogen Inc. developed a residential-scale Coal Water Slurry (CWS) combustor which makes use of centrifugal forces to separate and confine larger unburned coal particles in the furnace upper chamber. Various partitions are used to retard the axial, downward flow of these particles, and thus maximize their residence time in the hottest section of the combustor. By operating this combustor under staged conditions, the local stoichiometry in the primary zone can be controlled to minimize NO{sub x} emissions. During the first year of the program, work encompassed a literature search, developing an analytical model of the SO{sub 2} reactor, fabricating and assembling the initial prototype components, testing the prototype component, and estimating the operating and manufacturing costs.

Condensing economizers for small coal-fired boilers and furnaces  

SciTech Connect

Condensing economizers increase the thermal efficiency of boilers by recovering sensible and latent heat from exhaust gas. These economizers are currently being used commercially for this purpose in a wide range of applications. Performance is dependent upon application-specific factors affecting the utility of recovered heat. With the addition of a condensing economizer boiler efficiency improvements up to 10% are possible. Condensing economizers can also capture flue gas particulates. In this work, the potential use of condensing economizers for both efficiency improvement and control of particulate emissions from small, coal water slurry-fired boilers was evaluated. Analysis was done to predict heat transfer and particulate capture by mechanisms including: inertial impaction, interception, diffusion, thermophoretic forces, and condensation growth. Shell-and-tube geometries were considered with flue gas on the outside of Teflon-covered tubes. Experimental studies were done with both air- and water-cooled economizers refit to a small boiler. Two experimental arrangements were used including oil-firing with injection of flyash upstream of the economizer and direct coal water slurry firing. Firing rates ranged from 27 to 82 kW (92,000 to 280,000 Btu/hr). Inertial impaction was found to be the most important particulate capture mechanism and removal efficiencies to 95% were achieved. With the addition of water sprays directly on the first row of tubes, removal efficiencies increased to 98%. Use of these sprays adversely affects heat recovery. Primary benefits of the sprays are seen to be the addition of small impaction sites and future design improvements are suggested in which such small impactors are permanently added to the highest velocity regions of the economizer. Predicted effects of these added impactors on particulate removal and pressure drop are presented.

Blast furnace coke quality in relation to petroleum coke addition  

SciTech Connect

The incorporation of petroleum coke as an additive in industrial coking coal blends is a practice often used by steel companies. A suitable blast furnace coke produced by replacing part of the coking coal blend with a suitable petroleum coke (addition of 5 to 15%), was made by Great Lakes Carbon Corporation and successfully tested at several blast furnaces. This coke had lower reactivity, less ash and slightly higher sulfur content than coke made without the addition of petroleum coke. In contrast with these results, it has been reported in a BCRA study that additions of petroleum coke to a strong coking coal, above 5 wt%, increased coke reactivity. These differences may be explained on the basis of the coal or blend characteristics to which petroleum coke is added. Petroleum coke addition seems to give better results if the coal/blend has high fluidity. The present situation in Spain is favorable for the use of petroleum coke. So, a study of laboratory and semi-industrial scale was made to assess the possibility of using petroleum coke as an additive to the typical industrial coal blend coked by the Spanish Steel Company, ENSIDESA. The influence of the petroleum coke particle size was also studied to semi-industrial scale.

Pyrometer with a probe beam superimposed on its field-of-view for furnace temperature measurements. The pyrometer includes a heterodyne millimeter/sub-millimeter-wave or microwave receiver including a millimeter/sub-millimeter-wave or microwave source for probing. The receiver is adapted to receive radiation from a surface whose temperature is to be measured. The radiation includes a surface emission portion and a surface reflection portion which includes the probe beam energy reflected from the surface. The surface emission portion is related to the surface temperature and the surface reflection portion is related to the emissivity of the surface. The simultaneous measurement of surface emissivity serves as a real time calibration of the temperature measurement. In an alternative embodiment, a translatable base plate and a visible laser beam allow slow mapping out of interference patterns and obtaining peak values therefor. The invention also includes a waveguide having a replaceable end portion, an insulating refractory sleeve and/or a source of inert gas flow. The pyrometer may be used in conjunction with a waveguide to form a system for temperature measurements in a furnace. The system may employ a chopper or alternatively, be constructed without a chopper. The system may also include an auxiliary reflector for surface emissivity measurements.

Determination of heliostat and concentrator size for solar furnace facilities  

SciTech Connect

There are basically two types of solar furnaces -- a vertical-beam or a horizontal-beam facility. A vertical-beam facility uses movable heliostats to redirect the incoming solar energy vertically upward to a stationary parabolid. A horizontal-beam furnace uses the heliostat to redirect the incoming energy horizontally to the paraboloid. This paper presents a method to determine the optimum size of the heliostat and/or concentrator to meet predetermined design criteria. Usually the concentrator size is fixed by the temperature and flux-density required at the test plane and the problem is to size the heliostat so the facility can be used for a certain length of time each day during the entire year. However, the method can also be used when the heliostat size is fixed and the concentrator size must be determined. The analysis considers energy incident from the sun being reflected from a flat spectral surface (heliostat) onto a concentrating surface (concentrator), which then redirects the energy to a focal spot that can then be used as a high temperature, high-flux density source. The analysis uses the basic relations of geometric optics and considers only the central ray of the incoming cone of energy from the sun. Errors involved with this assumption will be minimal for most cases, but if deemed necessary, the reflected cone can be accounted for in the reflected ray from the heliostat.

An Integrated Model of Coal/Coke Combustion in a Blast Furnace  

Science Journals Connector (OSTI)

A three?dimensional integrated mathematical model of the combustion of pulverized coal and coke is developed. The model is applied to the region of lance?blowpipe?tuyere?raceway?coke bed to simulate the operation of pulverized coal injection in an ironmaking blast furnace. The model integrates two parts: pulverized coal combustion model in the blowpipe?tuyere?raceway?coke bed and the coke combustion model in the coke bed. The model is validated against the measurements in terms of coal burnout and gas composition respectively. The comprehensive in?furnace phenomena are simulated in the raceway and coke bed in terms of flow temperature gas composition and coal burning characteristics. In addition underlying mechanisms for the in?furnace phenomena are analyzed. The model provides a cost?effective tool for understanding and optimizing the in?furnace flow?thermo?chemical characteristics of the PCI process in full?scale blast furnaces.

On numerical simulation of flow, heat transfer and combustion processes in tangentially-fired furnace  

SciTech Connect

In this work, an Eulerian/Lagrangian approach has been employed to investigate numerically flow characteristics, heat transfer and combustion processes inside corner-fired power plant boiler furnace. To avoid pseudo-diffusion that is significant in modeling tangentially-fired furnaces, some attempts have been made at improving the finite-difference scheme. Comparisons have been made between standard {kappa}-{epsilon} model and RNG {kappa}-{epsilon} model. Some new developments on turbulent diffusion of particles are taken into account in an attempt to improve computational accuracy. Finally, temperature deviation is studied numerically so as to gain deeper insight into tangentially fired furnace.

Coal-oil mixture combustion program: injection into a blast furnace  

SciTech Connect

A chemically stabilized coal-oil mixture (COM) was made and used as an auxiliary fuel in a blast furnace for 44 days. Approximately 485,000 gallons of COM were produced at an on-site COM plant. Composition was 47.9% coal, 47.6% No. 6 oil, 4.0% water, and 0.5% emulsifier. Average injection rates were 3.8 to 13.0 gpm during different periods of the trial. Coal handling equipment, mixing and processing equipment, pumps, piping, fuel lances, and instrumentation are discussed. The blast furnace performance during the trial is compared to a Base Period of injecting No. 6 oil. Blast furnace performance was satisfactory, with one pound of COM replacing one pound of coke or 0.8 pound of No. 6 oil. The production of COM and its usage in a blast furnace is economical and feasible.

Air Pollution  

Science Journals Connector (OSTI)

Both natural processes and human activities contribute to air pollution, with the combustion of fossil fuels being the largest anthropogenic source of air pollutants. Adverse health effects (above all respiratory and cardiovascular complications), damage to crops, natural vegetation and materials, reduced visibility and changed radiation balance of the atmosphere are the major consequences of high concentrations of air pollutants. Technical fixes can sharply reduce emissions from large stationary sources and lower the rates of automotive emissions, but the rising number of vehicles and longer time spent on the road will call for more radical solutions to traffic-generated photochemical smog now present in all major urban areas.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF). Quarterly progress report No. 3, July--September 1992  

SciTech Connect

A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluate the economic and technical feasibility of the concept, and prepare an R & D plan to develop the concept further. Foster Wheeler Development Corporation is leading a team ofcompanies involved in this effort. The system proposed to meet these goals is a combined-cycle system where air for a gas turbine is indirectly heated to approximately 1800{degrees}F in furnaces fired with cool-derived fuels and then directly heated in a natural-gas-fired combustor up to about 2400{degrees}F. The system is based on a pyrolyzing process that converts the coal into a low-Btu fuel gas and char. The fuelgas is a relatively clean fuel, and it is fired to heat tube surfaces that are susceptible to corrosion and problems from ash deposition. In particular, the high-temperature air heater tubes, which will need tobe a ceramic material, will be located in a separate furnace or region of a furnace that is exposed to combustion products from the low-Btu fuel gas only. A simplified process flow diagram is shown.

Evaluation of Retrofit Variable-Speed Furnace Fan Motors  

SciTech Connect

In conjunction with the New York State Energy Research and Development Authority (NYSERDA) and Proctor Engineering Group, Ltd. (PEG), the Consortium for Advanced Residential Buildings (CARB) has evaluated the Concept 3 (tm) replacement motors for residential furnaces. These brushless, permanent magnet (BPM) motors can use much less electricity than their PSC (permanent split capacitor) predecessors. This evaluation focuses on existing homes in the heating-dominated climate of upstate New York with the goals of characterizing field performance and cost-effectiveness. The results of this study are intended to be useful to home performance contractors, HVAC contractors, and home efficiency program stakeholders. The project includes eight homes in and near Syracuse, NY. Tests and monitoring was performed both before and after fan motors were replaced. Average fan power reductions were approximately 126 Watts during heating and 220 Watts during cooling operation. Over the course of entire heating and cooling seasons, these translated into average electric energy savings of 163 kWh. Average cost savings were $20 per year. Homes where the fan was used outside of heating and cooling mode saved an additional $42 per year on average. Results indicate that BPM replacement motors will be most cost-effective in HVAC systems with longer run times and relatively low duct static pressures. More dramatic savings are possible if occupants use the fan-only setting when there is no thermal load. There are millions of cold-climate, U.S. homes that meet these criteria, but the savings in most homes tested in this study were modest.

Comparative analysis of failure probability for ethylene cracking furnace tube using Monte Carlo and API RBI technology  

Science Journals Connector (OSTI)

Abstract Ethylene cracking furnace tube is one of the most critical components in the petrochemical industry to crack molecules at high temperature. The furnace tube degrades easily during operations which would cause equipment failure and lead to serious consequences, such as fire and explosion. In this work, a quantitative analysis of failure probability for the ethylene cracking furnace tube is performed using the Monte Carlo method and API Risk-Based Inspection (RBI) technology. The results have shown that the operation life of ethylene cracking furnace tube under interaction of creep and carburization is less than that under creep, and the failure probability calculated based on API RBI technology is lower than that using the Monte Carlo method. Moreover, the comparative analysis results prove further that creep and carburization are two main failure modes of the furnace tube rupture. Therefore, it is very necessary to provide reliable data to perform risk assessment and inspections on ethylene cracking furnace tube.

Recovery Act: ArcelorMittal USA Blast Furnace Gas Flare Capture  

SciTech Connect

The U.S. Department of Energy (DOE) awarded a financial assistance grant under the American Recovery and Reinvestment Act of 2009 (Recovery Act) to ArcelorMittal USA, Inc. (ArcelorMittal) for a project to construct and operate a blast furnace gas recovery boiler and supporting infrastructure at ArcelorMittals Indiana Harbor Steel Mill in East Chicago, Indiana. Blast furnace gas (BFG) is a by-product of blast furnaces that is generated when iron ore is reduced with coke to create metallic iron. BFG has a very low heating value, about 1/10th the heating value of natural gas. BFG is commonly used as a boiler fuel; however, before installation of the gas recovery boiler, ArcelorMittal flared 22 percent of the blast furnace gas produced at the No. 7 Blast Furnace at Indiana Harbor. The project uses the previously flared BFG to power a new high efficiency boiler which produces 350,000 pounds of steam per hour. The steam produced is used to drive existing turbines to generate electricity and for other requirements at the facility. The goals of the project included job creation and preservation, reduced energy consumption, reduced energy costs, environmental improvement, and sustainability.

Economics of residential gas furnaces and water heaters in United States new construction market  

SciTech Connect

New single-family home construction represents a significant and important market for the introduction of energy-efficient gas-fired space heating and water-heating equipment. In the new construction market, the choice of furnace and water-heater type is primarily driven by first cost considerations and the availability of power vent and condensing water heaters. Few analysis have been performed to assess the economic impacts of the different combinations of space and water-heating equipment. Thus, equipment is often installed without taking into consideration the potential economic and energy savings of installing space and water-heating equipment combinations. In this study, we use a life-cycle cost analysis that accounts for uncertainty and variability of the analysis inputs to assess the economic benefits of gas furnace and water-heater design combinations. This study accounts not only for the equipment cost but also for the cost of installing, maintaining, repairing, and operating the equipment over its lifetime. Overall, this study, which is focused on US single-family new construction households that install gas furnaces and storage water heaters, finds that installing a condensing or power-vent water heater together with condensing furnace is the most cost-effective option for the majority of these houses. Furthermore, the findings suggest that the new construction residential market could be a target market for the large-scale introduction of a combination of condensing or power-vent water heaters with condensing furnaces.

A Feasibility Study for Recycling Used Automotive Oil Filters In A Blast Furnace  

SciTech Connect

This feasibility study has indicated that of the approximately 120,000 tons of steel available to be recycled from used oil filters (UOF's), a maximum blast furnace charge of 2% of the burden may be anticipated for short term use of a few months. The oil contained in the most readily processed UOF's being properly hot drained and crushed is approximately 12% to 14% by weight. This oil will be pyrolized at a rate of 98% resulting in additional fuel gas of 68% and a condensable hydrocarbon fraction of 30%, with the remaining 2% resulting as carbon being added into the burden. Based upon the writer's collected information and assessment, there appears to be no operational problems relating to the recycling of UOF's to the blast furnace. One steel plant in the US has been routinely charging UOF's at about 100 tons to 200 tons per month for many years. Extensive analysis and calculations appear to indicate no toxic consideration as a result of the pyrolysis of the small contained oil ( in the 'prepared' UOFs) within the blast furnace. However, a hydrocarbon condensate in the ''gasoline'' fraction will condense in the blast furnace scrubber water and may require additional processing the water treatment system to remove benzene and toluene from the condensate. Used oil filters represent an additional source of high quality iron units that may be effectively added to the charge of a blast furnace for beneficial value to the operator and to the removal of this resource from landfills.

Apparatus having inductively coupled coaxial coils for measuring buildup of slay or ash in a furnace  

DOE Patents (OSTI)

The buildup of slag or ash on the interior surface of a furnace wall is monitored by disposing two coils to form a transformer which is secured adjacent to the inside surface of the furnace wall. The inductive coupling between the two coils of the transformer is affected by the presence of oxides of iron in the slag or ash which is adjacent to the transformer, and the application of a voltage to one winding produces a voltage at the other winding that is related to the thickness of the slag or ash buildup on the inside surface of the furnace wall. The output of the other winding is an electrical signal which can be used to control an alarm or the like or provide an indication of the thickness of the slag or ash buildup at a remote location.

Development of the Household Sample for Furnace and Boiler Life-Cycle Cost Development of the Household Sample for Furnace and Boiler Life-Cycle Cost Analysis Title Development of the Household Sample for Furnace and Boiler Life-Cycle Cost Analysis Publication Type Report LBNL Report Number LBNL-55088 Year of Publication 2005 Authors Whitehead, Camilla Dunham, Victor H. Franco, Alexander B. Lekov, and James D. Lutz Document Number LBNL-55088 Pagination 22 Date Published May 31 Publisher Lawrence Berkeley National Laboratory City Berkeley Abstract Residential household space heating energy use comprises close to half of all residential energy consumption. Currently, average space heating use by household is 43.9 Mbtu for a year. An average, however, does not reflect regional variation in heating practices, energy costs, or fuel type. Indeed, a national average does not capture regional or consumer group cost impacts from changing efficiency levels of heating equipment. The US Department of Energy sets energy standards for residential appliances in, what is called, a rulemaking process. The residential furnace and boiler efficiency rulemaking process investigates the costs and benefits of possible updates to the current minimum efficiency regulations. Lawrence Berkeley National Laboratory (LBNL) selected the sample used in the residential furnace and boiler efficiency rulemaking from publically available data representing United States residences. The sample represents 107 million households in the country. The data sample provides the household energy consumption and energy price inputs to the life-cycle cost analysis segment of the furnace and boiler rulemaking. This paper describes the choice of criteria to select the sample of houses used in the rulemaking process. The process of data extraction is detailed in the appendices and is easily duplicated.The life-cycle cost is calculated in two ways with a household marginal energy price and a national average energy price. The LCC results show that using an national average energy price produces higher LCC savings but does not reflect regional differences in energy price.

Piezoresistive cantilever force-clamp system  

SciTech Connect

We present a microelectromechanical device-based tool, namely, a force-clamp system that sets or ''clamps'' the scaled force and can apply designed loading profiles (e.g., constant, sinusoidal) of a desired magnitude. The system implements a piezoresistive cantilever as a force sensor and the built-in capacitive sensor of a piezoelectric actuator as a displacement sensor, such that sample indentation depth can be directly calculated from the force and displacement signals. A programmable real-time controller operating at 100 kHz feedback calculates the driving voltage of the actuator. The system has two distinct modes: a force-clamp mode that controls the force applied to a sample and a displacement-clamp mode that controls the moving distance of the actuator. We demonstrate that the system has a large dynamic range (sub-nN up to tens of {mu}N force and nm up to tens of {mu}m displacement) in both air and water, and excellent dynamic response (fast response time, <2 ms and large bandwidth, 1 Hz up to 1 kHz). In addition, the system has been specifically designed to be integrated with other instruments such as a microscope with patch-clamp electronics. We demonstrate the capabilities of the system by using it to calibrate the stiffness and sensitivity of an electrostatic actuator and to measure the mechanics of a living, freely moving Caenorhabditis elegans nematode.

Co-combustion of refuse derived fuel and coal in a cyclone furnace at the Baltimore Gas and Electric Company, C. P. Crane Station  

SciTech Connect

A co-combustion demonstration burn of coal and fluff refuse-derived fuel (RDF) was conducted by Teledyne National and Baltimore Gas and Electric Company. This utility has two B and W cyclone furnaces capable of generating 400 MW. The facility is under a prohibition order to convert from No. 6 oil to coal; as a result, it was desirable to demonstrate that RDF, which has a low sulfur content, can be burned in combination with coals containing up to 2% sulfur, thus reducing overall sulfur emissions without deleterious effects. Each furnace consists of four cyclones capable of generating 1,360,000 pounds per hour steam. The tertiary air inlet of one of the cyclones was modified with an adapter to permit fluff RDF to be pneumatically blown into the cyclone. At the same time, coal was fed into the cyclone furnace through the normal coal feeding duct, where it entered the burning chamber tangentially and mixed with the RDF during the burning process. Secondary shredded fluff RDF was prepared by the Baltimore County Resource Recovery Facility. The RDF was discharged into a receiving station consisting of a belt conveyor discharging into a lump breaker, which in turn, fed the RDF into a pneumatic line through an air-lock feeder. A total of 2316 tons were burned at an average rate of 5.6 tons per hour. The average heat replacement by RDF for the cyclone was 25%, based on Btu input for a period of forty days. The range of RDF burned was from 3 to 10 tons per hour, or 7 to 63% heat replacement. The average analysis of the RDF (39 samples) for moisture, ash, heat (HHV) and sulfur content were 18.9%, 13.4%, 6296 Btu/lb and 0.26% respectively. RDF used in the test was secondary shredded through 1-1/2 inch grates producing the particle size distribution of from 2 inches to .187 inches. Findings to date after inspection of the boiler and superheater indicate satisfactory results with no deleterious effects from the RDF.

Thermophotovoltaic furnacegenerator for the home using low bandgap GaSb cells  

Science Journals Connector (OSTI)

It is well known that distributed combined heat and power (CHP) systems for commercial and industrial buildings are economically desirable because they conserve energy. Here, a thermophotovoltaic (TPV) unit is described that brings CHP into the home providing both heat and electric power by replacing the typical home heating furnace with a combined TPV furnacegenerator. First, the design of a 1.5 kWelectric/12.2 kWthermal TPV furnacegenerator is described along with the key components that make it possible. Diffused junction GaSb cells are one of these key components. Secondly, an economic cost target is determined for this system where the cost of the photovoltaic array will be key to the economical implementation of this concept. Finally, it is argued that the GaSb cells and arrays can be manufactured at the required low cost. The cost target can be reached because the GaSb cells in the TPV furnacegenerator can produce an electrical power density of 1 W cm?2 which is 100 times higher than the typical solar cell. The cost target can also be reached because the GaSb cell fabrication process parallels the silicon solar cell process where no toxic gases are used, no wafer polish is required and cast polycrystalline cells can be used.

Dofasco`s No. 4 blast furnace hearth breakout, repair and rescue  

SciTech Connect

On May 5, 1994, after producing 9.5 million metric tons of iron, Dofasco`s No. 4 Blast Furnace experienced a hearth breakout 250 millimeters below the west taphole. The hot metal spill caused a fire resulting in severe damage and 33 days of lost production. During a 26-day period, electrical wiring, water drainage systems and both tapholes were repaired. Recovery from an unprepared furnace stop of this length, with the deadman depleted is difficult. To aid with the rescue Hoogovens-designed oxygen/fuel lances were commissioned. The furnace recovery began with a lance in each taphole and all tuyeres plugged. Six days after startup the furnace was casting into torpedo cars, and after nine days operation had returned to normal. This incident prompted Dofasco to expand the hearth monitoring system to detect and prevent similar occurrences. During the repair, 203 new thermocouples were installed in the hearth, concentrating on the tapholes and elephant foot areas. These thermocouples were installed at various depths and locations to allow heat flux calculations. This hearth monitoring system has already identified other problem areas and provided valuable information about hearth drainage patterns. This information has allowed them to develop control strategies to manage localized problem areas.

Pulverized coal firing of aluminum melting furnaces. Second annual technical progress report, July 1979-June 1980  

SciTech Connect

The ultimate objective of this program is the commercial demonstration of an efficient, environmentally acceptable coal firing process suitable for implementation on melting furnaces throughout the aluminum industry. To achieve this goal, the program has been divided into two phases. Phase I has proceeded through design and construction of a 350 pound (coal) per hour staged slagging cyclone combustor (SSCC) attached to a 7-ft diameter aluminum melting ladle furnace. Process development will culminate with a 1000 pph prototype SSCC firing a 40,000 pound capacity open hearth melting furnace at the Alcoa Laboratories. Phase II implementation is currently planned for Alcoa's Lafayette, IN, Works, where two of the ingot plant's five open hearth melting furnaces will be converted to utilize coal. In addition to confirmation of data gathered in Phase I, the effect of extended production schedule operation on equipment and efficiencies will be determined. This work would begin in 1982 pursuant to technical and economic evaluation of the process development at that time.

Using coal-dust fuel in Ukrainian and Russian blast furnaces  

SciTech Connect

Ukrainian and Russian blast-furnace production falls short of the best global practices. It is no secret that, having switched to oxygen and natural gas in the 1960s, the blast-furnace industries have improved the batch and technological conditions and have attained a productivity of 2.5 and even 3 t/(m{sup 3} day), but have not been able to reduce coke consumption below 400 kg/t, which was the industry standard 40 years ago. The situation is particularly bad in Ukraine: in 2007, furnace productivity was 1.5-2 t/m{sup 3}, with a coke consumption of 432-530 kg/t. Theoretical considerations and industrial experience over the last 20 years show that the large-scale introduction of pulverized fuel, with simultaneous improvement in coke quality and in batch and technological conditions, is the only immediately available means of reducing coke consumption considerably (by 20-40%). By this means, natural-gas consumption is reduced or eliminated, and the efficiency of blast-furnace production and ferrous metallurgy as a whole is increased.

A review of NO[sub x] formation mechanisms in recovery furnaces  

SciTech Connect

Review of NOx formation studies shows that NO forms in recovery furnaces primarily by two independent mechanisms, thermal and fuel. Thermal NO formation is extremely temperature-sensitive. However, theoretical predictions indicate that recovery furnace temperatures are not high enough to form significant thermal NO. Fuel NO formation is less temperature-sensitive, and is related to fuel nitrogen content. Black liquors are shown to contain 0.05 to 0.24 weight percent fuel nitrogen. Conversion of just 20% of this would yield approximately 25-120 ppm NOx (at 8% 0[sub 2]) in the flue gas, enough to represent the majority of the total NOx. Data from operating recovery furnaces show NOx emissions ranging from near zero to over 100 ppm at 8% 0[sub 2]. An apparent increase in recovery furnace NOx emissions was observed with increasing solids. This increase is much less than predicted by thermal NO formation theory, indicating that other NO formation/destruction mechanisms, such as fuel NO formation, are important. No data are available to show the relative importance of thermal and fuel NO to total NOx during black liquor combustion.

Coulomb force as an entropic force  

SciTech Connect

Motivated by Verlinde's theory of entropic gravity, we give a tentative explanation to the Coulomb's law with an entropic force. When trying to do this, we find the equipartition rule should be extended to charges and the concept of temperature should be reinterpreted. If one accepts the holographic principle as well as our generalizations and reinterpretations, then Coulomb's law, the Poisson equation, and the Maxwell equations can be derived smoothly. Our attempt can be regarded as a new way to unify the electromagnetic force with gravity, from the entropic origin. Possibly some of our postulates are related to the D-brane picture of black hole thermodynamics.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF). Quarterly progress report No. 7, July--September 1993  

SciTech Connect

A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluating the economic and technical feasibility of the concept, and preparing an R&D plan to develop the concept further. Foster Wheeler Development Corporation (FWDC) is leading a team of companies involved in this effort. The power generating system being developed in this project will be an improvement over current coal-fired systems. Goals have been specified that relate to the efficiency, emissions, costs, and general operation of the system. The system proposed to meet these goals is a combined-cycle system where air for a gas turbine is indirectly heated to approximately 1800{degrees}F in furnaces fired with coal-derived fuels and then directly heated in a natural-gas-fired combustor to about 2400{degrees}F. The system is based on a pyrolyzing process that converts the coal into a low-Btu fuel gas and char. The fuel gas is relatively clean, and it is fired to heat tube surfaces that are susceptible to corrosion and problems from ash deposition. In particular, the high-temperature air heater tubes, which will need to be a ceramic material, will be located in a separate furnace or region of a furnace that is exposed to combustion products from the low-Btu fuel gas only. A simplified process flow diagram is shown in Figure 1.

AISI/DOE Technology Roadmap Program Hot Oxygen Injection Into The Blast Furnace  

SciTech Connect

Increased levels of blast furnace coal injection are needed to further lower coke requirements and provide more flexibility in furnace productivity. The direct injection of high temperature oxygen with coal in the blast furnace blowpipe and tuyere offers better coal dispersion at high local oxygen concentrations, optimizing the use of oxygen in the blast furnace. Based on pilot scale tests, coal injection can be increased by 75 pounds per ton of hot metal (lb/thm), yielding net savings of $0.84/tm. Potential productivity increases of 15 percent would yield another $1.95/thm. In this project, commercial-scale hot oxygen injection from a ''thermal nozzle'' system, patented by Praxair, Inc., has been developed, integrated into, and demonstrated on two tuyeres of the U.S. Steel Gary Works no. 6 blast furnace. The goals were to evaluate heat load on furnace components from hot oxygen injection, demonstrate a safe and reliable lance and flow control design, and qualitatively observe hot oxygen-coal interaction. All three goals have been successfully met. Heat load on the blowpipe is essentially unchanged with hot oxygen. Total heat load on the tuyere increases about 10% and heat load on the tuyere tip increases about 50%. Bosh temperatures remained within the usual operating range. Performance in all these areas is acceptable. Lance performance was improved during testing by changes to lance materials and operating practices. The lance fuel tip was changed from copper to a nickel alloy to eliminate oxidation problems that severely limited tip life. Ignition flow rates and oxygen-fuel ratios were changed to counter the effects of blowpipe pressure fluctuations caused by natural resonance and by coal/coke combustion in the tuyere and raceway. Lances can now be reliably ignited using the hot blast as the ignition source. Blowpipe pressures were analyzed to evaluate ht oxygen-coal interactions. The data suggest that hot oxygen increases coal combustion in the blow pipe and tuyere by 30, in line with pilot scale tests conducted previously.

Note: Electrical resolution during conductive atomic force microscopy measurements under different environmental conditions and contact forces  

SciTech Connect

Conductive atomic force microscopy experiments on gate dielectrics in air, nitrogen, and UHV have been compared to evaluate the impact of the environment on topography and electrical measurements. In current images, an increase of the lateral resolution and a reduction of the conductivity were observed in N{sub 2} and, especially, in UHV (where current depends also on the contact force). Both effects were related to the reduction/elimination of the water layer between the tip and the sample in N{sub 2}/UHV. Therefore, since current measurements are very sensitive to environmental conditions, these factors must be taken into consideration when comparisons between several experiments are performed.

Thermal-destruction products of coal in the blast-furnace gas-purification system  

SciTech Connect

The lean, poorly clinkering coal and anthracite used to replace coke in blast furnaces has a considerable content of volatile components (low-molecular thermaldestruction products), which enter the water and sludge of the blast-furnace gas-purification system as petroleum products. Therefore, it is important to study the influence of coal on the petroleum-product content in the water and sludge within this system. The liberation of primary thermal-destruction products is investigated for anthracite with around 4 wt % volatiles, using a STA 449C Jupiter thermoanalyzer equipped with a QMC 230 mass spectrometer. The thermoanalyzer determines small changes in mass and thermal effects with high accuracy (weighing accuracy 10{sup -8} g; error in measuring thermal effects 1 mV). This permits experiments with single layers of coal particles, eliminating secondary reactions of its thermal-destruction products.

Computational Fluid Dynamics (CFD) Modeling for High Rate Pulverized Coal Injection (PCI) into the Blast Furnace  

SciTech Connect

Pulverized coal injection (PCI) into the blast furnace (BF) has been recognized as an effective way to decrease the coke and total energy consumption along with minimization of environmental impacts. However, increasing the amount of coal injected into the BF is currently limited by the lack of knowledge of some issues related to the process. It is therefore important to understand the complex physical and chemical phenomena in the PCI process. Due to the difficulty in attaining trus BF measurements, Computational fluid dynamics (CFD) modeling has been identified as a useful technology to provide such knowledge. CFD simulation is powerful for providing detailed information on flow properties and performing parametric studies for process design and optimization. In this project, comprehensive 3-D CFD models have been developed to simulate the PCI process under actual furnace conditions. These models provide raceway size and flow property distributions. The results have provided guidance for optimizing the PCI process.

Sonoluminescing air bubbles rectify argon  

E-Print Network (OSTI)

The dynamics of single bubble sonoluminescence (SBSL) strongly depends on the percentage of inert gas within the bubble. We propose a theory for this dependence, based on a combination of principles from sonochemistry and hydrodynamic stability. The nitrogen and oxygen dissociation and subsequent reaction to water soluble gases implies that strongly forced air bubbles eventually consist of pure argon. Thus it is the partial argon (or any other inert gas) pressure which is relevant for stability. The theory provides quantitative explanations for many aspects of SBSL.

Development of the household sample for furnace and boilerlife-cycle cost analysis  

SciTech Connect

Residential household space heating energy use comprises close to half of all residential energy consumption. Currently, average space heating use by household is 43.9 Mbtu for a year. An average, however, does not reflect regional variation in heating practices, energy costs, or fuel type. Indeed, a national average does not capture regional or consumer group cost impacts from changing efficiency levels of heating equipment. The US Department of Energy sets energy standards for residential appliances in, what is called, a rulemaking process. The residential furnace and boiler efficiency rulemaking process investigates the costs and benefits of possible updates to the current minimum efficiency regulations. Lawrence Berkeley National Laboratory (LBNL) selected the sample used in the residential furnace and boiler efficiency rulemaking from publically available data representing United States residences. The sample represents 107 million households in the country. The data sample provides the household energy consumption and energy price inputs to the life-cycle cost analysis segment of the furnace and boiler rulemaking. This paper describes the choice of criteria to select the sample of houses used in the rulemaking process. The process of data extraction is detailed in the appendices and is easily duplicated. The life-cycle cost is calculated in two ways with a household marginal energy price and a national average energy price. The LCC results show that using an national average energy price produces higher LCC savings but does not reflect regional differences in energy price.

RADIATION HEAT TRANSFER ENVIRONMENT IN FIRE AND FURNACE TESTS OF RADIOACTIVE MATERIALS PAKCAGES  

SciTech Connect

The Hypothetical Accident Conditions (HAC) sequential test of radioactive materials packages includes a thermal test to confirm the ability of the package to withstand a transportation fire event. The test specified by the regulations (10 CFR 71) consists of a 30 minute, all engulfing, hydrocarbon fuel fire, with an average flame temperature of at least 800 C. The requirements specify an average emissivity for the fire of at least 0.9, which implies an essentially black radiation environment. Alternate test which provide equivalent total heat input at the 800 C time averaged environmental temperature may also be employed. When alternate tests methods are employed, such as furnace or gaseous fuel fires, the equivalence of the radiation environment may require justification. The effects of furnace and open confinement fire environments are compared with the regulatory fire environment, including the effects of gases resulting from decomposition of package overpack materials. The results indicate that furnace tests can produce the required radiation heat transfer environment, i.e., equivalent to the postulated pool fire. An open enclosure, with transparent (low emissivity) fire does not produce an equivalent radiation environment.

FURN3D: A computer code for radiative heat transfer in pulverized coal furnaces  

SciTech Connect

A computer code FURN3D has been developed for assessing the impact of burning different coals on heat absorption pattern in pulverized coal furnaces. The code is unique in its ability to conduct detailed spectral calculations of radiation transport in furnaces fully accounting for the size distributions of char, soot and ash particles, ash content, and ash composition. The code uses a hybrid technique of solving the three-dimensional radiation transport equation for absorbing, emitting and anisotropically scattering media. The technique achieves an optimal mix of computational speed and accuracy by combining the discrete ordinate method (S[sub 4]), modified differential approximation (MDA) and P, approximation in different range of optical thicknesses. The code uses spectroscopic data for estimating the absorption coefficients of participating gases C0[sub 2], H[sub 2]0 and CO. It invokes Mie theory for determining the extinction and scattering coefficients of combustion particulates. The optical constants of char, soot and ash are obtained from dispersion relations derived from reflectivity, transmissivity and extinction measurements. A control-volume formulation is adopted for determining the temperature field inside the furnace. A simple char burnout model is employed for estimating heat release and evolution of particle size distribution. The code is written in Fortran 77, has modular form, and is machine-independent. The computer memory required by the code depends upon the number of grid points specified and whether the transport calculations are performed on spectral or gray basis.

SciTech Connect

Industrial test data are presented regarding the production (at Sokolovsk-Sarbaisk mining and enrichment enterprise) and blast-furnace smelting (at Magnitogorsk metallurgical works) of boron-alloyed iron-ore pellets (500000 t). It is shown that, thanks to the presence of boron, the compressive strength of the roasted pellets is increased by 18.5%, while the strength in reduction is doubled; the limestone consumption is reduced by 11%, the bentonite consumption is halved, and the dust content of the gases in the last section of the roasting machines is reduced by 20%. In blast-furnace smelting, the yield of low-sulfur (<0.02%) hot metal is increased from 65-70 to 85.1% and the furnace productivity from 2.17-2.20 to 2.27 t/(m{sup 3} day); coke consumption is reduced by 3-8 kg/t of hot metal. The plasticity and stamping properties of 08IO auto-industry steel are improved by microadditions of boron.

Development of high temperature air combustion technology in pulverized fossil fuel fired boilers  

SciTech Connect

High temperature air combustion (HTAC) is a promising technology for energy saving, flame stability enhancement and NOx emission reduction. In a conventional HTAC system, the combustion air is highly preheated by using the recuperative or regenerative heat exchangers. However, such a preheating process is difficult to implement for pulverized fossil fuel fired boilers. In this paper, an alternative approach is proposed. In the proposed HTAC system, a special burner, named PRP burner is introduced to fulfill the preheating process. The PRP burner has a preheating chamber with one end connected with the primary air and the other end opened to the furnace. Inside the chamber, gas recirculation is effectively established such that hot flue gases in the furnace can be introduced. Combustible mixture instead of combustion air is highly preheated by the PRP burner. A series of experiments have been conducted in an industrial scale test facility, burning low volatile petroleum coke and an anthracite coal. Stable combustion was established for burning pure petroleum coke and anthracite coal, respectively. Inside the preheating chamber, the combustible mixture was rapidly heated up to a high temperature level close to that of the hot secondary air used in the conventional HTAC system. The rapid heating of the combustible mixture in the chamber facilitates pyrolysis, volatile matter release processes for the fuel particles, suppressing ignition delay and enhancing combustion stability. Moreover, compared with the results measured in the same facility but with a conventional low NOx burner, NOx concentration at the furnace exit was at the same level when petroleum coke was burnt and 50% less when anthracite was burnt. Practicability of the HTAC technology using the proposed approach was confirmed for efficiently and cleanly burning fossil fuels. 16 refs., 10 figs., 1 tab.

Combustion of high-sulfur coal and anthracite wastes in a rotary kiln combustor with an advanced internal air distributor  

SciTech Connect

Fluid bed combustors have received extensive testing with both high-sulfur coal and anthracite wastes. Rotary kilns are effective and popular devices for waste combustion. The Angelo Rotary Furnace{trademark} has been developed to improve the operation of rotary pyrolyzer/combustor systems through enhanced air distribution, which in this process is defined as staged, swirled combustion air injection. Fourteen of these new furnaces have been installed worldwide. Two units in Thailand, designed for rice hull feed with occasional lignite feed, have been recently started up. An older unit in Pennsylvania is being upgraded with a new, more advanced air distribution system for a series of tests this fall in which inexpensive high-sulfur coal and anthracite wastes will be fired with limestone. The purposes of these tests are to determine the burning characteristics of these two fuels in this system, to discover the Ca/S ratios necessary for operation of a rotary kiln combusting these fuels, and to observe the gas-borne emissions from the furnace. An extensive preliminary design study will be performed on a commercial installation for combustion of anthracite wastes. 14 refs., 5 figs., 1 tab.

Direct Aerosol Forcing Uncertainty  

DOE Data Explorer (OSTI)

Understanding sources of uncertainty in aerosol direct radiative forcing (DRF), the difference in a given radiative flux component with and without aerosol, is essential to quantifying changes in Earth's radiation budget. We examine the uncertainty in DRF due to measurement uncertainty in the quantities on which it depends: aerosol optical depth, single scattering albedo, asymmetry parameter, solar geometry, and surface albedo. Direct radiative forcing at the top of the atmosphere and at the surface as well as sensitivities, the changes in DRF in response to unit changes in individual aerosol or surface properties, are calculated at three locations representing distinct aerosol types and radiative environments. The uncertainty in DRF associated with a given property is computed as the product of the sensitivity and typical measurement uncertainty in the respective aerosol or surface property. Sensitivity and uncertainty values permit estimation of total uncertainty in calculated DRF and identification of properties that most limit accuracy in estimating forcing. Total uncertainties in modeled local diurnally averaged forcing range from 0.2 to 1.3 W m-2 (42 to 20%) depending on location (from tropical to polar sites), solar zenith angle, surface reflectance, aerosol type, and aerosol optical depth. The largest contributor to total uncertainty in DRF is usually single scattering albedo; however decreasing measurement uncertainties for any property would increase accuracy in DRF. Comparison of two radiative transfer models suggests the contribution of modeling error is small compared to the total uncertainty although comparable to uncertainty arising from some individual properties.

CONDENSING ECONOMIZERS FOR SMALL COAL-FIRED BOILERS AND FURNACES PROJECT REPORT - JANUARY 1994  

SciTech Connect

Condensing economizers increase the thermal efficiency of boilers by recovering sensible and latent heat from exhaust gas. These economizers are currently being used commercially for this purpose in a wide range of applications. Performance is dependent upon application-specific factors affecting the utility of recovered heat. With the addition of a condensing economizer boiler efficiency improvements up to 10% are possible. Condensing economizers can also capture flue gas particulates. In this work, the potential use of condensing economizers for both efficiency improvement and control of particulate emissions from small, coal water slurry-fired boilers was evaluated. Analysis was done to predict heat transfer and particulate capture by mechanisms including: inertial impaction, interception, diffusion, thermophoretic forces, and condensation growth. Shell-and-tube geometries were considered with flue gas on the outside of Teflon-covered tubes. Experimental studies were done with both air- and water-cooled economizers refit to a small boiler. Two experimental arrangements were used including oil-firing with injection of flyash upstream of the economizer and direct coal water slurry firing. Firing rates ranged from 27 to 82 kW (92,000 to 280,000 Btu/hr). Inertial impaction was found to be the most important particulate capture mechanism and removal efficiencies to 95% were achieved. With the addition of water sprays directly on the first row of tubes, removal efficiencies increased to 98%. Use of these sprays adversely affects heat recovery. Primary benefits of the sprays are seen to be the addition of small impaction sites and future design improvements are suggested in which such small impacts are permanently added to the highest velocity regions of the economizer. Predicted effects of these added impactors on particulate removal and pressure drop are presented.

Burden distribution control for maintaining the central gas flow at No. 1 blast furnace in Pohang Works  

SciTech Connect

The causes for temperature lowering at the upper shaft center in Pohang No. 1 blast furnace were investigated. The test operation with charging notch change in the actual blast furnace and with a 1/12 scale model to Pohang No. 1 blast furnace were carried out in order to improve central gas flow in the shaft. Finally, rebuilding of the lower bunker interior was performed using the results of model experiments. It was confirmed that the main reason for the gas temperature lowering at the upper shaft center was the smaller particle size at center than the wall according to the discharging characteristics of center feed bunker with stone box. The central gas flow could be secured through modifying the stone box in the bunker.

A Miniature Maxthal Furnace for X-ray Spectroscopy and Scattering Experiments up to 1200 degrees C  

SciTech Connect

We have built a new small furnace to perform high temperature studies up to 1200 deg. C in vacuum or in oxygen atmosphere. This furnace was originally used as a catalytic reactor optimized for the in situ X-ray Absorption Spectroscopy experiments on beamline ID24. It has now been redesigned for use on the ESRF beamline ID01 for in situ Grazing Incidence Small Angle X-ray Scattering experiments. For these experiments high mechanical stability of the sample holder is necessary to keep the alignment of the sample during heating.

Modified entropic force  

SciTech Connect

The theory of statistical thermodynamics tells us the equipartition law of energy does not hold in the limit of very low temperatures. It is found the Debye model is very successful in explaining the experimental results for most of the solid objects. Motivated by this fact, we modify the entropic force formula which is proposed very recently. Since the Unruh temperature is proportional to the strength of the gravitational field, so the modified entropic force formula is an extension of the Newtonian gravity to the weak field. On the contrary, general relativity extends Newtonian gravity to the strong field case. Corresponding to Debye temperature, there exists a Debye acceleration g{sub D}. It is found the Debye acceleration is g{sub D}=10{sup -15} N kg{sup -1}. This acceleration is very much smaller than the gravitational acceleration 10{sup -4} N kg{sup -1} which is felt by Neptune and the gravitational acceleration 10{sup -10} N kg{sup -1} felt by the Sun. Therefore, the modified entropic force can be very well approximated by the Newtonian gravity in the Solar System and in the Galaxy. With this Debye acceleration, we find the current cosmic speeding up can be explained without invoking any kind of dark energy.

Air-driven Brazil nut effect  

Science Journals Connector (OSTI)

A large heavy object may rise to the top of a bed of smaller particles under the influence of vertical vibration, the Brazil nut effect. Recently it has been noted that interstitial air can influence the Brazil nut rise time. Here we report that the air movement induced by vertical vibration produces a very strong Brazil nut effect for fine granular beds. We use a porous-bottomed box to investigate the mechanism responsible for this effect and to demonstrate that it is related to the piling of fine beds, first reported by Chladni and studied by Faraday. Both effects are due to the strong interaction of the fine particles with the air, as it is forced through the bed by the vibration.
