1972-1997, Twenty-five years of energy and environmental history : lessons learned.

Description: Given the events of the past 25 years concerning energy and environmental issues and our reaction to them, what lessons can we learn? First, the individual American consumer wants and expects energy to be a stable commodity with low prices and easy availability. As evidenced by the heated debate over increasing the federal gasoline tax by $.05 per gallon (which would still leave Americans paying only one-third of what Europeans pay for gasoline), increases in energy prices elicit very strong pu… more

Advanced ceramics for land-based gas turbine applications. Final report

Description: In order to increase the efficiency of land-based gas turbines, inlet gas temperatures have to be increased, and the amount of air which cools the turbine vanes has to be reduced, to the maximum extent possible. Presently, thermal barrier coatings (TBC`s) are the state of the art in achieving these goals. However, since TBC`s are very thin (typically 100 {mu}m), they have clearly limitations. Since all-ceramic turbine vanes would be a very large and risky development step, Westinghouse is consi… more

[Advanced turbine systems, conceptual design and product development]. Final quarterly technical progress report, 1 August 1996--1 January 1997

Description: This quarterly report covers activities on key tasks for two quarters, from August 1996 to October 1996, and from November 1996 to January 1997, respectively. The reason for combining the two quarterly periods into one report is because of the vastly reduced scope of work remaining on this contract. Allison continued progress on the following tasks during these two quarters: Task 5--Market Study; Task 8.07--Ceramic Vane Design and Evaluation; and Task 9.0--Program Management.

Ceramic vane demonstration in an industrial turbine

Description: A DOE program with Allison Engine Co. will demonstrate ceramic vanes in an industrial turbine. First-stage ceramic vanes and metallic mounts are to be designed, fabricated, and operated in a short-term engine test (up to 50 hr). The vanes and mounts will then be retrofitted into an existing turbine for operation at a commercial site for up to 8000 hr. They have been designed. Thermal and stress analyses of the vanes have calculated acceptable fast fracture stress levels and probabilities of sur… more

Conversion of Solar Two to a Kokhala hybrid power tower

Description: The continued drop in energy prices and restructuring of the utility industry have reduced the likelihood that a follow-on commercial 100-MW, power tower project will be built immediately following the Solar Two demonstration project. Given this, it would be desirable to find a way to extend the life of the Solar Two project to allow the plant to operate as a showcase for future power tower projects. This paper looks at the possibility of converting Solar Two into a commercial Kokhala hybrid po… more

Effects of ambient conditions and fuel composition on combustion stability

Description: Recent regulations on NO, emissions are promoting the use of lean premix (LPM) combustion for industrial gas turbines. LPM combustors avoid locally stoichiometric combustion by premixing fuel and the air upstream of the reaction region, thereby eliminating the high temperatures that produce thermal NO.. Unfortunately, this style of combustor is prone to combustion oscillation. Significant pressure fluctuations can occur when variations in heat release periodically couple pressure to acoustic mo… more

High Temperature Electrochemical Polishing of H{sub 2}S from Coal Gasification Process Streams. Quarterly Progress Report, April 1, 1996--June 30, 1996

Description: Coal may be used to generate electrical energy by any of several processes, most of which involve combustion or gasification. Combustion in a coal-fired boiler and power generation using a steam-cycle is the conventional conversion method; however total energy conversion efficiencies for this type of process are only slightly over 30%. Integration of a gas-cycle in the process (combined cycle) may increase the total conversion efficiency to 40%. Conversion processes based on gasification offer … more

Life cycle assessment of a biomass gasification combined-cycle power system

Description: The potential environmental benefits from biomass power are numerous. However, biomass power may also have some negative effects on the environment. Although the environmental benefits and drawbacks of biomass power have been debated for some time, the total significance has not been assessed. This study serves to answer some of the questions most often raised in regard to biomass power: What are the net CO{sub 2} emissions? What is the energy balance of the integrated system? Which substances … more
