A Rational Efficiency Analysis of Comparisons and Trends in Gas Turbines for Cogeneration (original) (raw)

Volume 3: Heat Transfer; Electric Power, 1985

Abstract

The performance of gas turbines in cogeneration is examined by means of a second-law approach. Different cycle parameters, for both simple and regenerative design, are investigated together with different options for process or utility heat production. A reference electric power size of 4 MW is assumed for these comparisons. Results are presented as a set of parameters (electric power index, rational efficiency, coefficient of utilization). A new parameter, named versatility index, effectively indicates the broadness of the design thermal loads which can be handled by a gas turbine plant.
