Gas turbine operation with liquid fuel vaporization

摘要

The power output of a gas turbine is increased by vaporizing a liquid coolant fuel at the inlet of the air compressor, which cools the air and increases the mass throughput of the compressor. The method preferably is used in a gas turbine-driven power generation system for increased power output and particularly during periods of high ambient temperatures or at a high site elevation. The liquid coolant fuel also can be introduced simultaneously into the gas turbine combustor to supplement the normal combustor fuel.
