| 摘 要： | 生物质半焦作为生物质气化的副产物,其固定碳含量和热值均高于原生物质.若将生物质半焦充分利用将大幅提高生物质利用的能量效率,具有很大的经济和环境效益.在综合热分析基础上,考察了生物质半焦添加比例(掺烧比)对生物质微米燃料旋风炉燃烧炉膛温度、烟气及灰分的影响.试验研究发现掺烧比为20%(空气当量比为1.2,粉体粒径在0.177 mm以下,生物质含水率控制在8.1%以下),燃烧效果最好,燃烧效率高达98%,燃烧烟气中有害气体NOx和SO2的含量较少.

| Abstract: | Biochar is a byproduct from gasification, therefore its fixed carbon content and heating value are generally higher than raw biomass. The energy efficiency of biomass utilization would significantly increase and would have great economic and environmental benefits if biochar could be fully utilized. We investigated that the effects of biochar blending ratio on combustion temperature, exhaust and ash content in a cyclone furnace based on the thermogravimetric analysis. The optimal combustion performance was observed when biochar blend ratio was 20% (equivalence ratio 1.2, biomass powder particle size < 0.177 mm, biomass moisture content < 8.1%). We discovered that combustion efficiency was 98% with less the harmful gas content (NOx and SO2) in flue gas. |
