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.

Abstract: 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 & clean device.

Key words: biomass briquettes, biomass boiler, combustion, air distribution
