Discussion on the technology of gas-steam combined cycle

Power plant is the main place of producing power in China,and it's continuous power operation has a decisive role for maintaining social power consumption.With the rapid development of market economy,industrialized mass production is the inevitable trend of national economic development in the future,which puts forward a severe challenge to the power supply capability of power plant.Considering from the view of power supply performance and energy saving and consumption reduction,thermal power plants must adopt gas-steam combined cycle technology.Based on analyzing the development prospect of gas-steam combined cycle technology,this paper introduces several main flue gas desulphurization dust removal technology of coal-fired boiler from the aspect of environmental protection.
