Exergetic optimization of itnercooled reheat chemically recuperated gas turbine

摘要

The capabilities of the chemical recuperation of exhaust and compressor intercooling heat form gas turbines have been investgiated in this paper considering methanol as primary fuel for the Reheat InterCooled (intercooler heat is recovered) Aeroderivative Gas Turbine. The model includes an exergy analysis method and a simplified blase cooling model. The location of the intercooler, the reheat combustion chamber as wel as the overall pressure ratio have been optimized. Comparisons are made with the Chemically Recuperated Gas Turbine CRGT cycles using methane as a primary fuel.
