Combined-cycle cogeneration analytics with microcomputer

Process industries that require the distribution of heat energy through a steam system are nearly certain to have some potential increases favorably as the differential increases between the thermal states of steam production and steam use. The application of efficient steam turbines maximizes the conversion of available heat to the desirable shaft power. Where gas turbine exhaust its net shaft power will also offset purchased power. The analytics of steam/gas turbine combined-cycles can best be performed by the use of representative thermodynamic models of the complex systems. The paper will describe methods and techniques of using microcomputers to evaluate the thermodynamic feasibility and economic merit of combined-cycle plants. 7 figures.
