This paper describes the first phase of an intended project to develop a reheat combustor-power turbine (RCPT) package which when added to an aircraft derivative gas generator would produce a commercially attractive reheat gas turbine for combined cycle and cogeneration applications. This first phase includes the identification of gas generators and establishes the relative merits of the RCPT package at various inlet temperatures based upon evaluated benefits. Our calculations show that in combined cycle application with the RCPT at an easily feasible power turbine inlet temperature of 1700°F, the steam flow increases by approximately 2.5 times, the combined cycle power by about 30%, and the combined cycle efficiency by about 5% compared to an unfired aeroderivative combined cycle. Compared to the duct fired combined cycle with the same power output, the efficiency increases by approximately 7.5%, leading to a lower cost of electricity of about 10 per cent for the economic assumptions of the study.
