The study focuses on the gas steam combined cycle power generation system using blast fur-nace gas,and analyzes the relationship between the inlet temperature,load,exhaust temperature,and turbine load of the gas turbine.When the inlet temperature of the gas turbine is below-16℃,the turbine load decreases by 12 MW;When the intake temperature of the gas turbine exceeds 20℃,the maximum load of the gas turbine is about 105 MW,which is 4 MW lower than the rated load.Both high and low gas temperatures will deteriorate the economic efficiency of the system.Adopting heating or cooling measures to maintain the intake temperature within a reasonable range can achieve the eco-nomic operation of gas steam combined cycle power generation systems.
