【Abstract】 This paper introduces the process selection, technical principle and process design of a waste incineration power generation flue gas desulfurization and denitrification. By analyzing the flue gas data, the application of sodium-based rotary spray drying(SDA) desulfurization method and low-temperature selective non-catalytic reduction(SNCR) denitration process in waste-to-energy incineration flue gas purification is discussed. The combination of the two can realize the synergistic removal of sulfur dioxide and nitrogen oxides in the waste incineration power generation flue gas, ensure the flue gas compliance discharge and the stable operation of the system, and provide reference for the engineering practice of waste incineration flue gas purification.更多还原
