燃气蒸汽联合循环的技术探讨

发电厂是我国电能生产的主要场所,其持续发电作业对于维持社会的用电有决定性作用。由于市场经济的快速发展,实现工业化大生产是未来国家经济发展的必然趋势,这对发电厂的供电能力提出了严峻的挑战。从供电性能、节能降耗两个角度考虑,热电厂必须采用燃气蒸汽联合循环技术。文章在分析燃气蒸汽联合循环技术发展前景的基础上,从环境保护角度介绍了燃煤锅炉几种主要的烟气脱硫除尘技术。

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.
