摘　　要：我国积极推进绿色低碳环保发展,而现阶段煤炭仍是主要能源之一,对燃煤发电机组进行节能与超低排放改造,降低大气污染物排放的工作刻不容缓。结合我国燃煤机组脱硫技术发展现状,论述了石灰石石膏法脱硫技术和氨法脱硫技术的工艺路线、特点,分析了两种技术的优缺点和运行成本、副产品的价值和危害。针对脱硫经济性与硫资源综合利用情况,建议推广氨法脱硫技术。China actively promotes the development of green,low-carbon and environmental protection.Coal is still one of the main energy sources at this stage.Therefore,it is urgent to carry out energy-saving and ultra-low emission transformation of coal-fired power generation units to reduce the emission of air pollutants.Combined with the development status of desulfurization technology of coal-fired units in China,this paper discusses the process route and characteristics of limestone gypsum desulfurization technology and ammonia desulfurization technology,and analyzes the advantages and disadvantages,construction and operation cost,value and harm of by-products of the two technologies.In view of the economy of desulfurization and the comprehensive utilization of sulfur resources,it is suggested to popularize the ammonia desulfurization technology.
