The input to be supplied to Combined Cycle Waste to Energy (C・C-WTE) system is waste incineration heat and combustion heat of gas turbine fuel. While the maximum temperature of working fluid by the former is usually 300℃, the temperature of that by the latter is approximately 1 200〜1 300℃. That is, the energy importance which the two heat gives to working fluids is much different. Therefore, an evaluation of C・C-WTE system based on heat capacity without energy importance sometimes brings unreasonable result from thermo-dynamics viewpoint. In this paper, C・C-WTE systems have been evaluated on exergy to be received by water/steam in waste heat boiler by incineration gas and chemical exergy of fuel to be inputted to gas turbine. The differences between exergy efficiency to be considered their energy worth, heat capacity due to enthalpy and repowering efficiency which has been studied in the former paper have been compared.
