摘　　要：生物质能具有碳零排放、可再生等特点。我国NO_(x)排放标准日趋严格,开展生物质锅炉氮氧化物排放控制技术研究至关重要。对燃料再燃、空气分级燃烧以及烟气再循环等低氮燃烧技术的原理及其国内外研究现状进行论述,分析生物质锅炉低氮燃烧技术存在的问题。通过总结分析,提出生物质锅炉低氮燃烧技术的研究应根据锅炉实际运行工况,重点对配风量、烟气再循环量等参数进行精准调控。Biomass energy has the characteristics of zero emission of carbon dioxide,renewable and so on.Chinese NO_(x) emission standards have become increasingly stringent,so it is very important to study the nitrogen oxide emission control technology of biomass boilers.The principle and research status of low nitrogen combustion technologies such as fuel recombustion,air graded combustion and flue gas recirculation were discussed,and the problems of low nitrogen combustion technology in biomass boiler were analyzed.Through summary and analysis,it was proposed that the research on biomass boiler low-nitrogen combustion technology should be focused on the precise regulation of air distribution volume,flue gas recirculation volume and other parameters according to the actual operating conditions of the boiler.
