A thermodynamic approach to the integrated design of a combined cycle cogeneration plant

A thermodynamically oriented approach for the integrated design of a combin ed cycle cogeneration plant (CCCP) meeting a given sites requirements for p rocess steam and power has been developed. It has been shown that the most efficient plant, for a targeted stack temperature, is achieved when the gas turbine cycle is designed for maximum specific net work and the steam turb ine cycle is designed for maximum cycle efficiency. Based on this approach a computer program for rigorous analysis has also been developed.
