Practical Analysis of Two Desulfurization and Denitrification Technologies for Gas Power Generation
Gas boilers produce CO,CO2,SO2 and other toxic and harmful gases during the combustion process,causing pollution to the environment.In recent years,flue gas desul-furization and denitrification technology has been widely used in order to enhance the eco-logical environment in China.There are two main types of gas boiler desulfurization and de-nitrification technologies,which are SNCR+fixed bed desulfurization and denitrification tech-nology and SCR+SDS+bag filter dust removal desulfurization and denitrification technology,both of which can effectively reduce the concentration of pollutants in the discharged flue gas.In order to determine the economy and practicability of the two desulfurization and de-nitrification processes currently used in Tangsteel New Area,two technologies were analyzed and compared in terms of production and operation costs,desulfurization and denitrification reaction efficiency,etc.,and it was concluded that SNCR+fixed bed desulfurization and deni-trification technology has a large operation and maintenance cost with a high desulfurization efficiency.SCR+SDS+bag filter dust removal desulfurization and denitrification technology has low operation and maintenance cost with a high denitrification efficiency.
