Closed Gas Turbine Heater Program. First Quarterly Technical Progress Report,April 1--July 3, 1977.

摘要

The objective of this program is to advance high-temperature closed gas turbine power conversion systems to a point of technological readiness for use in coal fired public utility power conversion plants. The initial contract addresses two specific problem areas. These are:the identification and analysis of system concepts which offer highest overall plant efficiency consistent with lowest cost of electricity (COE) from coal-pile-to-bus-bar;and the identification and preliminary design of combustor/heat exchanger concepts compatible for use as the cycle gas primary heater for those plant systems. System cycle analyses and parametric studies will be performed to evaluate entire closed gas turbine utility power plants,with and without Rankine bottoming cycles,with emphasis on lowest COE. Contract completion will result in utility plant layouts,component definitions,performance,technology assessment and costs for four heater systems. Two heater systems will be based on 1550exp 0 F closed gas turbine inlet temperature using metallic materials and two based on 1750exp 0 F and higher using non-metallic materials.
