The capabilities of the chemical recuperation of exhaust and compressor int
ercooling heat from gas turbines have been investigated in this paper consi
dering methanol as primary fuel for the Reheat InterCooled (intercooler hea
t is recovered) Aeroderivative Gas Turbine. The model includes an exergy an
alysis method and a simplified blade cooling model. The location of the int
ercooler, the reheat combustion chamber as well as the overall pressure rat
io have been optimized. Comparisons are made with the Chemically Recuperate
d Gas Turbine CRGT cycles using methane as a primary fuel. (C) 1999 Elsevie
