Abstract

A system for operating a combustor includes a nozzle and a fuel passage and diluent passage through the nozzle. A fuel supply is in fluid communication with the fuel inlet, and a diluent supply is in fluid communication with the diluent inlet and the fuel inlet. A method for operating a combustor includes flowing a fuel through a fuel inlet in a nozzle and flowing a diluent through a diluent inlet in the nozzle. The method further includes sensing an operating parameter of the combustor, generating a signal reflective of the operating parameter, and controlling a flow of at least one of air or diluent to the fuel inlet based on the signal reflective of the operating parameter.

Description

technical field [0001] The present invention generally relates to a system and method for operating a combustor. In particular embodiments, the systems and methods of the present invention may be used to operate combustors in gas turbines. Background technique [0002] Burners are generally used to ignite fuel to produce combustion gases with high temperature and pressure. For example, a gas turbine illustratively includes one or more combustors to generate power or thrust. An exemplary gas turbine for generating electrical power includes an axial compressor at the front, one or more combustors around the middle, and a turbine at the rear. Ambient air may be supplied into the compressor, and rotating blades and stationary vanes in the compressor gradually impart kinetic energy to the working fluid (air), thereby producing compressed working fluid in an energized state. The compressed working fluid exits the compressor and flows through one or more nozzles in each combusto...
