Optimization on fuel gas operation for combined cycle power plant
Fuel gas system for 13E2 gas turbine is designed to optimize the fuel gas consumption and reduce nitrogen oxide gas emission. This system consists of closed loop controller, control valves, shut off valves, and burners. Due to long running operation, the hardware of gas turbine efficiency will deter...
