An Analysis of the Performance of a Gas Turbine Cogeneration Plant

A computer program has been developed to analyze the thermodynamic performance of a cogeneration plant. Results of parametric studies using this program include partial load operation, inlet air cooling, and supercharging. Fuel chargeable to power, a previously used figure-of-merit, is used to evaluate the performance for partial-load operation. Fuel chargeable to incremental power and differential steam efficiency are two new figures-of-merit for evaluating other design alternatives: the former for incremental increases in electric power output, the latter for incremental increases in steam output at the expense of electrical power output.
