摘　　要：通过对多个生物质发电项目考察、调研,总结了各项目通过采取一系列环保工艺路线实现了生物质项目脱硝超低排放NO_(x)≤50 mg/m^(3)的情况。分别介绍了烟气回流、SNCR、COA氧化、PNCR、SCR、臭氧、ZYY干法脱硝工艺技术及各工艺在生物质发电项目中的实际应用情况和对比。对于生物质发电项目采用COA氧化脱硝技术、PNCR干法脱硝技术、臭氧脱硝技术、ZYY干法脱硝技术单独使用皆可实现NO_(x)超低排放要求,为了降低系统脱硝运行成本,通常与烟气回流和SNCR组合使用。最后,对生物质发电行业脱硝超低排放技改技术及政策提出进一步展望,如进一步研发锰系等抗碱金属催化剂,对技改项目提供必要补贴政策。It introduces the author’s study and research on several biomass power generation projects,and summarizes that each project has achieved ultra-low emission NO_(x)≤50 mg/m^(3)for denitrification of biomass projects by adopting a series of environmental protection process routes.The flue gas recirculation,SNCR,COA oxidation,PNCR,SCR,ozone,ZYY dry denitration process technologies,and the actual application and comparison of each process in biomass power generation projects were introduced.For biomass power generation projects,COA oxidation denitrification technology,PNCR dry denitration technology,ozone denitration technology,and ZYY dry denitration technology can be used alone to achieve ultra-low NO_(x)emission requirements.SNCR is used in combination.Finally,further prospects are put forward for the denitration and ultra-low emission technological transformation technologies and policies in the biomass power generation industry,such as further research and development of manganese series and other alkali-resistant catalysts,and necessary subsidy policies for technological transformation projects.
