Fluid injection gas turbine engine and method for operating

摘要: A gas turbine including at least a compressor, combustor, and is constructed to operate preferred thermal efficiency in predetermined compressor flow pressure ratios. fluid, such as steam, for example produced by waste heat pressurized water, characterized having higher specific constant than effluent from the combustor introduced into provide operating medium of improved potential transfer energy downstream combustor. Such injection provides effective variable geometry system. This system maintains ratios substantially independent engine power output.
