ABSTRACT:
A compression intercooled gas generator operating at high-cycle pressure ratios of 35 to 65 atmospheres to furnish hot pressurized gas sequentially to a diffuser, to a reheat combustor and then to a power turbine. An associated method of compression intercooling with an optimum intercooling pressure ratio to minimize overall combined-cycle efficiency degradation when said gas generator, diffuser, reheat combustor and power turbine are operating in conjunction with a heat-recovery boiler and a steam or vapor turbine. A coaxial shafting arrangement for driving the low-pressure and high-pressure compressor sections. A pressure-retaining casing arrangement enclosing the high-pressure portion of said gas generator to contain the higher than normal pressure of said gas generator.
