摘　　要：为解决目前生物质成型燃料燃烧机燃烧效率不高、尾气烟尘大、炉排易结渣且难以清除等问题,设计了处理量为500 kg/h,并采用分段燃烧方式的新型成型燃料燃烧机,进行了蒸汽锅炉供热试验。结果表明,锅炉功率5 300 MJ,燃烧效率99.36%。尾气中CO 0.001 45%,SO2、NOX等酸性气体为0.01%和0.06%。自动破渣除渣器可以将秸秆灰渣连续破除,有效防止了炉排结渣。In order to solve the problems in biomass briquette combustion including low efficiency, exhausting gas and smoke, slagging easily and difficulty to remove, we designed a new type of combustion machine which adopt staged combustion mode. The steam boiler heating experiments were conducted and the results showed that the output of boiler was 5 300 MJ and combustion efficiency was 99. 36 %. The combustion gas contained CO with 0. 001 45% and the contents of SO2 and NOX were 0. 01 % and 0. 06 %, respectively. Slag could be automatically broken and slagging-off under the help of automatic slag broken＆amp; clean device.
