Patent number: 9003764Abstract: A system includes a gas turbine engine that includes a compressor section configured to generate compressed air and a combustor coupled to the compressor section. The combustor is configured to combust a first mixture comprising the compressed air and a first fuel to generate a first combustion gas. The gas turbine engine also includes a turbine section coupled to the combustor. The turbine section is configured to expand the first combustion gas to generate an exhaust gas. The gas turbine engine also includes a boiler coupled to the turbine section. The boiler is configured to combust a second mixture comprising a portion of the first combustion gas and a second fuel to generate a second combustion gas that is routed to the turbine section. In addition, the boiler generates a first steam from heat exchange with the second combustion gas.Type: GrantFiled: December 16, 2011Date of Patent: April 14, 2015Assignee: General Electric CompanyInventors: Pradeep Stanley Thacker, Aaron John Avagliano

Patent number: 8420031Abstract: A system includes a radiant syngas cooler (RSC). The RSC includes cooling tubing configured to transmit a fluid. The RSC is configured to have a heat transfer area such that the RSC generates a pressure and a temperature of the fluid exiting the RSC to a level allowing for superheating of the fluid to between approximately 750° Fahrenheit and approximately 850° Fahrenheit. Additionally, the heat transfer area is determined based on an amount of heat to be transferred to the fluid as the fluid passes through a heat exchanger in a first path external to the RSC.Type: GrantFiled: October 19, 2010Date of Patent: April 16, 2013Assignee: General Electric CompanyInventor: Pradeep Stanley Thacker
