锯末制备生物质成型燃料的试验研究

Experimental study on preparation of biomass briquette fuel by sawdust

分别采用冷压成型和炭化成型工艺以锯末制备生物质成型燃料。冷压成型工艺主要考察原料水分、成型压力对燃料的成型性能影响。试验结果表明：原料水分为12％～16％，成型压力为60MPa的条件下能够制得成型性能较好的生物质成型燃料，其密度与抗跌强度分别能够达到0．94g/cm^3和99％；炭化成型工艺主要考察混合料水分、无烟煤配比、J型粘结剂添加量、成型压力对燃料的成型性能影响。试验结果表明：无烟煤配比为50％、混合料水分为30％、J型粘结剂添加量为8％、成型压力为45MPa的条件下能够制得成型性能较好的优质生物质成型燃料，其密度与抗跌强度分别为0．93g/cm^3和99.3％。

Biomass briquette fuel was prepared by sawdust in the techniques of cold briquetting and carbonized briquetting. The effects of material moisture content and forming pressure of cold briquetting technique on forming properties of the briquette fuel was studied. The results show that the product biomass briquette fuel has a good forming properties when material moisture content was 12%-16% and forming pressure was 60 MPa, and the density was 0.94 g/era3 and shatter strength was 99%. The effect of mix moisture content, anthracite ratio, addition of J binder and forming pressure of carbonized briquetting technique on forming properties of the briquette fuel was stuied. The experiments results show that the product superior biomass briquette fuel has a good forming properties when anthracite ratio was 50%, mix moisture content was 30%, addition of J binder was 8%, forming pressure was 45 MPa, and the density was 0.93 g/cm3 and shatter strength was 99.3%.
