Patent number: 6804612Abstract: Automated systems for performing integrated analyses. In one embodiment, an integrated analysis system can be used to comprehensively evaluate the effects of changes in hardware configuration or operating conditions on gas turbine power plant performance and economics. The system evaluates these changes by concurrently analyzing a number of different aspects of the power plant while ensuring that the data used in each of the different analyses is consistent. These analyses can include turbine and compressor aerodynamic analysis, cooling and leakage flow analysis, heat transfer analysis, part life analysis, heat balance analysis, cost analysis and overall power plant performance and economic analysis.Type: GrantFiled: October 30, 2001Date of Patent: October 12, 2004Assignee: General Electric CompanyInventors: Cedric Chow, Kelly Crotty, John Drohan, James Fehlberg, Arlie Russell Martin, Thad Morton, Todd Nemec, David Pesetsky, Robert Russell Priestley, Ming Zhou

Patent number: 6526758Abstract: A land based gas turbine plant includes a turbine compressor, a turbine section, and a combustor between the compressor and the turbine section. A heat recovery boiler incorporating at least one heat exchange section is arranged to receive exhaust gas from the turbine section, the heat recovery boiler receiving water passed in heat exchange relationship with the exhaust gas to produce steam. An external compressor supplies augmenting combustion air that is mixed with the steam produced in the heat recovery boiler to produce a mixture of steam and air that is injected into the combustor.Type: GrantFiled: April 17, 2001Date of Patent: March 4, 2003Assignee: General Electric CompanyInventors: Jatila Ranasinghe, Robert Russell Priestley

Patent number: 6446440Abstract: A steam injection and inlet fogging system is provided for a gas turbine power plant that includes a gas turbine having a compressor, a combustor and a turbine for driving a generator. A waste heat recovery unit is arranged to receive exhaust gas from the turbine, the former having a plurality of heat exchange sections for heating water with the exhaust gas. A flash tank is arranged to receive heated water from the waste heat recovery unit for producing steam. A first stream of makeup water from a first of the plurality of heat exchange sections is flashed to the flash tank to also produce saturated steam and water at a first location in the flash tank. A second stream of water from a second of the plurality of heat exchange sections is also flashed to the flash tank to produce saturated steam and water at a second location in the flash tank.Type: GrantFiled: September 15, 2000Date of Patent: September 10, 2002Assignee: General Electric CompanyInventors: Jatila Ranasinghe, Charles Michael Jones, Robert Russell Priestley

Patent number: 6357218Abstract: A heat rejection system is provided in a recirculating flow line, so that the steam production rate can be controlled from no steam production to maximum steam production for the gas turbine operating condition. For maximum steam production, the heat exchanger of the heat rejection system is bypassed so all the water is directed to the heat recovery unit (HRU). When no steam production is desired, all or a majority of the water is directed to the heat exchanger such that the heat absorbed in the HRU evaporator is equal to the heat rejected by the air cooled heat exchanger. Adjusting the flow split between these two limits allows the steam production rate to vary from no production to the maximum steam production capability corresponding to the gas turbine operating point.Type: GrantFiled: June 20, 2001Date of Patent: March 19, 2002Assignee: General Electric CompanyInventors: Jatila Ranasinghe, Charles Michael Jones, Robert Russell Priestley
