Patent number: 6634165Abstract: A water-injection control system is disclosed for a water supersaturation system installed in a gas turbine air intake system for augmenting gas turbine power output during operation at high ambient-air temperature, while maintaining the water content in the intake air within limits acceptable to the gas turbine as indicated by measured gas turbine operating parameters. The control system starts, stops, modulates, and limits water supplied to the supersaturating system based on the humidity or dew-point temperature of the ambient air, dry-bulb temperature of the ambient air, compressor inlet air flow, and gas turbine parameters indicating operation at or near maximum output.Type: GrantFiled: December 28, 2000Date of Patent: October 21, 2003Assignee: General Electric CompanyInventors: Leroy Omar Tomlinson, Richard Robert Trewin

Patent number: 6397575Abstract: In a combined cycle system having a multi-pressure heat recovery steam generator, a gas turbine and steam turbine, steam for cooling gas turbine components is supplied from the intermediate pressure section of the heat recovery steam generator supplemented by a portion of the steam exhausting from the HP section of the steam turbine, steam from the gas turbine cooling cycle and the exhaust from the HP section of the steam turbine are combined for flow through a reheat section of the HRSG. The reheated steam is supplied to the IP section inlet of the steam turbine. Thus, where gas turbine cooling steam temperature is lower than optimum, a net improvement in performance is achieved by flowing the cooling steam exhausting from the gas turbine and the exhaust steam from the high pressure section of the steam turbine in series through the reheater of the HRSG for applying steam at optimum temperature to the IP section of the steam turbine.Type: GrantFiled: March 23, 2000Date of Patent: June 4, 2002Assignee: General Electric CompanyInventors: Leroy Omar Tomlinson, Raub Warfield Smith
