Baseline Gas Turbine Development Program. Eleventh quarterly progress report

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. NASA completed initial heat balance testing of a baseline engine. An additional 450 hours were run on ceramic regenerators and seals. Seal wear rates are very good, and the elastomeric mounting system was satisfactory. An engine/control oil supply system based on the power steering pump is successfully operating in baseline vehicles. The design of the upgraded engine power turbine nozzle actuator was finalized, and layouts of the inlet guide vane actuator are in process. A lock-up torque converter was installed in the free rotor vehicle. Baseline engine and vehicle testing of water injection and variable inlet guide vanes was completed. A thermal analysis of the gas generator is in process. A steady-state, full power analysis was made. A three-dimensional stress analysis of the compressor cover was made. The power turbine nozzle actuating system layout was completed. The analytical studies of the power turbine rotor bearings were completed. MTI completed the design of the gas generator rotor simulation fixture and is starting to build it. Optimized reduction gears were successfully tested in a baseline engine.

Geothermal direct contact heat exchange. Final report

Description: A glass direct contact heat exchange column was operated in the laboratory. The column was operated at atmospheric pressure using hot water and normal hexane. Column internals testing included an empty column, sieve trays, disk-and-doughnut trays, and two types of packing. Operation was very smooth in all cases and the minimum temperature approaches varied from less than 1/sup 0/C for packing to 13/sup 0/C for the empty column. High heat transfer rates were obtained in all cases, however, columns should be sized on the basis of liquid and vapor traffic. The solubilities of hydrocarbons were determined for normal hexane, pentane and butane in water and sodium chloride and calcium chloride brines at various temperatures. The values seem to be internally consistent and salt content was found to depress hydrocarbon solubility. Laboratory stripping tests showed that gas stripping can be used to remove hydrocarbon from reject hot water from the direct contact heat exchange column. Although the gas volumes required are small, stripping gas requirements cannot be accurately predicted without testing. A computer program was used to study the effect of operating variables on the thermodynamic cycle efficiencies. Optimum efficiencies for the moderate brine conditions studied were obtained with isopentane as working fluid and relatively low operating pressure. A preliminary design for a 50 MWe plant was prepared and plant capital cost and operating cost were estimated. These costs were combined with previously developed brine production and power transmission costs to provide an estimate of the cost of delivered power for a geothermal field at Heber, California. A pilot plant program is described that would be suitable for continuing the investigation of the direct contact process in the field. The program includes a suggested schedule and the estimated cost.

Prototype pilot plant operation: Synthane process. Contractor quarterly operation report No. 11, April 1--June 30, 1977

Description: Runs 1-DB-G to J were conducted from March 31 to April 6. Gas was produced for 76 hours. Feed rates and bed heights were varied at operating temperatures of 1500/sup 0/F in an attempt to achieve over 70% carbon conversion. The Plant was finally shut down on April 6 after a clinker formed in the gasifier. Carbon conversions up to 70% were achieved during the later stages of the run. The Plant was operated April 15 to 16 and again April 27 to 28. During both of these runs, emphasis was placed on attempting to make the internal cyclone operate. Run 1-DB-K lasted only 17 hours and Run 1-DB-L, only 15 hours. Both of these runs were terminated due to the formation of clinkers. Considerable improvement was noted in the solids carryover into gas scrubbing. The fines return to the bed resulted in much lower densities and poor bed level control was experienced. The gasifier was operated for a period of 8 days in May at varying conditions, in an attempt to achieve better operability with low bed densities. The gasifier was shut down after a crack developed in Incoloy 800 Nozzle No. 50 before the test program could be fully completed. The nozzle failed as a result of stress corrosion cracking. These findings necessitated the removal of all 22 similar Incoloy 800 nozzles. All nozzles are being replaced with carbon steel flanges that are monel overlaid.

Resource utilization efficiency improvement of geothermal binary cycles: Phase I. Annual report, June 15, 1975--June 15, 1976

Description: The following were performed: (1) evaluation of the advantages and disadvantages of the use of mixtures as working fluids in geothermal binary cycles, (2) development of a geothermal binary cycle simulation computer program capable of both mixture and pure fluid cycle simulation, (3) development of an accurate thermodynamic properties computer program package (applicable as a minimum to hydrocarbon mixture and pure fluid cycles), (4) comparison of mixture and pure fluid cycles, including relative equipment sizing and economics, (5) comparison of boiling and condensing heat transfer for mixtures and pure fluids, (6) evaluation of the advantages and disadvantages of turbine expansion into the two-phase region, and (7) sensitivity analysis of various binary cycle equipment parameters and operating conditions on total geothermal power system cost. A primary conclusion from the Phase I investigation is that mixtures offer advantages over pure working fluids in situations where there is a mismatch of resource brine and pure fluid characteristics.

Prototype Pilot Plant Operation, Synthane Process. Contractor monthly activity report No. 36, August 1--August 31, 1977

Description: Progress achieved during August 1977 at the Synthane Pilot Plant located in Bruceton, Pennsylvania, is reported. The plant operated from August 5 to August 16 during which time 465 tons of Rosebud coal were gasified. During this period, oxygen and coal were fed for 190 hours, 98 hours of which were without interruption. The run produced ten steady state periods. Bed temperatures and feed rates were varied to study the effect of these variables on conversions. Carbon conversions of 75 percent to 78 percent were achieved for extended periods of operation at feed rates of 2 to 3 tons per hour. The successful completion of this run finishes studies of Western subbituminous coal. The Plant is presently preparing for the gasification of Illinois No. 6 coal.

Technical evaluation of the waste-to-oil process development facility at Albany, Oregon

Description: The broad objective of ERDA's solar energy program at Albany, Oregon, is to develop biomass-to-synfuel technology in the Albany process development facility, which is now nearing completion. In the study reported here, the process development plant design was reevaluated, and a number of modifications and additions are recommended to facilitate and accelerate development of biomass conversion processes. Sketches of the recommended modifications and estimates of costs and installation time schedules have been provided. It has been found expedient to implement some of these modifications before construction is completed. Biomass-to-synfuel processes under development or under consideration elsewhere have been reviewed, and some have been identified that are appropriate for further development at Albany. Potential environmental impacts associated with the operation of the Albany, Oregon, facility were reviewed to identify the magnitude of the impacts and the effects of any resultant operational constraints. Two discrete environmental impact categories have been identified with respect to process development operation. These are (1) production, storage, and disposal of product oil and residual solid, liquid, and gaseous waste; and (2) disturbances to the local community. An assessment has been made of unit process waste discharges and mitigation procedures, environmental setting and community considerations, possible operational constraints, and monitoring programs.

Baseline Gas Turbine Development Program ninth quarterly progress report

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. NASA completed the first phase of their baseline engine heat balance tests, and an upgraded engine compressor is being scaled for test. EPA completed their report on vehicle tests including emissions and vehicle performance, and a new endurance engine is on test. Significant development progress was made on both fixed and variable geometry combustors. After 45 hours of engine operation with Vendor A ceramic regenerator, no significant deterioration of the matrix, seals, or elastomeric mount was encountered. Ceramic regenerator stress analysis has commenced. Additional developments in non-nickel oxide regenerator rubbing seals are encouraging. The first preprototype integrated control system is in vehicle operation. Control adaptation for variable inlet guide vanes and water injection is progressing. AiRefrac turbine wheels were verified dimensionally and are being processed for engine testing. Water injection tests with a four nozzle system were run, and additional performance documentation of variable inlet guide vanes was obtained. Linerless insulation is on test in the free rotor engine, the new endurance engine, and a performance engine. The free rotor engine completed test cell checkout and was installed in a vehicle. Vehicle checkout, including a preprototype integrated control, is underway. Detailed specifications of the upgraded engine were written.

Effects of atmospheric variability on energy utilization and conservation. Summary of research conducted between 1 July 1975 and 31 March 1976

Description: Studies of atmospheric variability revealed that the 22- to 26-day vacillation in the potential and kinetic energy modes of the Northern Hemisphere is related to the behavior of the planetary long-waves, and that the midwinter dip in zonal available potential energy is reflected in the development of blocking highs. Attempts to classify weather patterns over eastern and central United States have proceeded satisfactorily to the point where testing of our method for longer time periods appears desirable. A ''physical-adaptive'' model of energy demand and its response to changes in weather regimes is under development. This model includes parameters pertaining to engineering factors of building construction, to weather-related factors, and to socio-economic factors. Preliminary testing of this model yielded very encouraging results. Expansion of model applications to different types of structures and larger regions is presently under way. A CRT-display model for energy demand within the conterminous United States also has passed preliminary tests. A major effort was expended to obtain disaggregated data on energy use from utility companies within the United States. A report of these efforts is presented.

EDS coal liquefaction process development: Phase V. Quarterly technical progress report, January 1-March 31, 1984

Description: This report is the twenty-first Quarterly Technical Progress Report for US Department of Energy Cooperative Agreement No. DE-FC05-77ET10069 for EDS Coal Liquefaction Process Development Phase V. A detailed comparison of RCLU, CLPP, and ECLP yields has been initiated. This study builds off previous yield modeling results, which found that RCLU, CLPP, and ECLP yields were generally consistent given the scatter of the data, although some differences were noted. These pilot unit yield differences have now been quantified, and operating/configurational differences which account for some of them have been identified. Preliminary yield comparison results after correcting for these known process differences between the pilot plants indicate that: RCLU and CLPP yields are generally consistent; ECLP's conversion is about 5 lb/100 lb DAF coal lower than RCLU/CLPP at comparable operating conditions; and work has been initiated to define the EDS slurry preheater feed system design (based on slurry distributor manifold guidelines and coking correlation predictions, which influence furnace pass control issues such as slurry flow measurement). EDS hydrotreated naphtha showed a low level of systemic toxicity to rats exposed to the vapor six hours per day, five days per week for thirteen weeks.

EDS coal liquefaction process development: Phase V. Final technical progress report, Volume I

Description: All objectives in the EDS Cooperative Agreement for Phases III-B through V have been achieved for the RCLU pilot plants. EDS operations have been successfully demonstrated in both the once-through and bottoms recycle modes for coals of rank ranging from bituminous to lignitic. An extensive data base detailing the effects of process variable changes on yields, conversions and product qualities for each coal has been established. Continuous bottoms recycle operations demonstrated increased overall conversion and improved product slate flexibility over once-through operations. The hydrodynamics of the liquefaction reactor in RCLU were characterized through tests using radioactive tracers in the gas and slurry phases. RCLU was shown to have longer liquid residence times than ECLP. Support work during ECLP operations contributed to resolving differences between ECLP conversions and product yields and those of the small pilot plants. Solvent hydrogenation studies during Phases IIIB-V of the EDS program focused on long term activity maintenance of the Ni-MO-10 catalyst. Process variable studies for solvents from various coals (bituminous, subbituminous, and lignitic), catalyst screening evaluations, and support of ECLP solvent hydrogenation operations. Product quality studies indicate that highly cyclic EDS naphthas represent unique and outstanding catalytic reforming feedstocks. High volumes of high octane motor gasoline blendstock are produced while liberating a considerable quantity of high purity hydrogen.

Design information questionnaire for a model mixed oxide fuel fabrication facility. [IAEA form]

Description: The model fuel plant is based on the proposed Westinghouse Anderson, S.C., plant and is typical of plants that will be constructed and operated in 1980 to 1990. A number of plant systems and procedures are uncertain, and in these cases judgment was used in describing relevant parameters in order to provide a complete model on which to design an inspection plan. The model plant does not, therefore, strictly represent any planned facility nor does it strictly represent the ideas of Westinghouse on plant design and material accountability. This report is divided into two sections. The first section is the IAEA Design Information Questionnaire form that contains an outline of all information requested. The second section is a complete listing of design information. (DLC)

Establishment of the feasibility of a process capable of low cost, high volume production of silane, SiH/sub 4/. Low cost silicon solar array project, Task I. Quarterly progress report, July 1976--October 1976

Description: The study of a process for the low cost production of silane included laboratory investigations of the kinetics of the redistribution of dichlorosilane and trichlorosilane vapor over a tertiary amine ion exchange resin catalyst. The hydrogenation of SiCl/sub 4/ to form HSiCl/sub 3/ and the direct synthesis of H/sub 2/SiCl/sub 2/ from HCl gas and metallurigical silicon metal were also studied. The purification of SiH/sub 4/ using activated carbon adsorbent was studied along with a process for storing SiH/sub 4/ adsorbed on carbon. The latter makes possible a higher volumetric efficiency than the current practice of compressed gas storage. The mini-plant designed to produce ten pounds per day of SiH/sub 4/ is nearly complete, a detailed description of the unit and its essential design features are given.

Baseline Gas Turbine Development Program eighth quarterly progress report

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. Major preparations for engine heat balance tests by NASA were completed. EPA laboratories completed Baseline vehicle emissions, noise, and odor tests. Assembly of the program endurance engine is nearing completion. Test cell evaluation of the government furnished combustor (Solar) verified steady state emissions to be extremely low. Initial engine tests of Vendor A ceramic regenerator cores with an elastomeric drive verified performance predictions. Efforts towards developing a non-nickel oxide regenerator seal show extreme sensitivity to porosity differences between cores of different suppliers. All three preprototype integrated control systems were built. Modifications are being worked out to achieve a stable low speed operation. Two prototype compressor turbine wheels made from the reuseable pattern process are being inspected and processed for testing. The engine housing modified for operation at higher cycle temperatures and pressures was received. The baseline engine converted to free rotor is completing test cell check out. The modified vehicle is ready for engine installation. The upgraded engine characterization was updated to include the latest information on V.I.G.V., rotors, and bearings. The upgraded engine housing is being modeled physically and analytically for design and stress studies. An accessory drive system for the upgraded engine was selected, and a final layout is in process.

Dynamic simulation of a sodium-cooled fast reactor power plant

Description: Simulation of the dynamic behavior of the Clinch River Breeder Reactor Plant (CRBRP) is the subject of this dissertation. The range of transients under consideration extends from a moderate transient, of the type referred to as Anticipated Transient Without Scram (ATWS), to a transient initiated by an unexpected accident followed by reactor scram. The moderate range of transients can be simulated by a digital simulator referred to as the CRBRP ATWS simulator. Two versions of this simulator were prepared; in one, the plant controllers were not included, whereas, in the other, the controllers were incorporated. A simulator referred to as the CRBRP-DCHT simulator was constructed for studying transients due to unexpected accidents followed by reactor scram. In this simulator emphasis was placed on simulating the auxiliary heat removal system, in order to determine its capability to remove the after-shut down fission and decay heat. The transients studied using the two versions of the ATWS simulator include step and ramp reactivity perturbations, and an electrical load perturbation in the controlled plant. An uncontrolled control rod withdrawal followed by reactor scram was studied using the DCHT simulator, although the duration of this transient was restricted to 20 sec. because of computer limitations. The results agree very well with the expected physical behavior of the plant.
