摘　　要：为解决现存生物质燃烧器结构设计不合理、燃烧效率低以及炉排易结渣等问题,依据生物质粉体燃料成分分析及其悬浮燃烧特性,通过优化设计和试验研制出一种新型结构的生物质悬浮燃烧器。在额定工况下,对设计出的生物质悬浮燃烧器进行了热性能试验。试验结果显示,燃烧效率可达98.26%,热效率83.7%,排烟损失11.8%,排烟中SO_2、NO_X等有害气体含量低于目前市场上推出的同容量生物质燃烧器,符合国家关于工业锅炉大气污染物排放标准的要求。To resolve the problems of the existing design of biomass burner structure with low combustion efficiency and grate slagging, a new structure of biomass suspension burner was designed through the optimization design and experiment, based on the combustion characteristics of biomass powder fuel composition analysis and suspension. Under the rated condition, the thermal performance test of the designed biomass suspension burner has been carried out. Figures indicate the combustion efficiency reached 98.26%, thermal efficiency reached 83.6%, smoke loss reached 11.8%. NOx, SO2 and other harmful emissions in boiler flue gases are lower than those of the biomass burner of the same capacity in the current market and meet the requirements of the national standards for the discharge of atmospheric pollutants in industrial boilers.
