ABSTRACT:
A compression intercooled gas turbine and vapor bottoming combined cycle system with the gas turbine operating at 30 to 65 atmospheres is disclosed. A twin spool hot gas generator incorporates compression intercooling at the optimum intercooler pressure ratio to (a) minimize intercooler heat rejection degradation, (b) raise the overall cycle pressure ratio, (c) increase gas generator core mass flow and (d) to increase the gas turbine power output. The gas turbine can operate in either the simple cycle or the reheat cycle mode for optimum combined cycle efficiency. A combined cycle efficiency upwards of 60 percent can be realized.
