摘要

Pressure and temperature are important parameters affecting the quality of biomass pellet fuel. In this paper 12% humidity mill mesh diameter 2mm, the pressure under the condition of 4. 5kN, study the effects of different temper-atures (80℃, 90℃, 100℃, 110℃, 120℃) on the molding quality of bacteria bract,sawdust andtobacco stalk biomass pellets. In 12% humidity, mill sieve diameter 2mm, temperature 100℃ conditions, study the effects of different pres-sures (1. 5, 3, 4. 5, 6, 7. 5kN) on the molding quality of the above three kinds of biomass pellets. Finally, through the comparison of the density and the radial pressure of the three kinds of biomass pellet fuel, find temperature and pressure of the molding quality of the three kinds of biomass pellets to be the best, which could provide reference for the produc-tion of different biomass pellet fuels.%压力和温度是影响生物质颗粒燃料成型品质的重要工艺参数。为此，在湿度12%、粉碎机筛眼直径2mm、压力4.5kN 的条件下，研究温度为80℃、90℃、100℃、110℃、120℃对菌苞、木屑和烟秆3种生物质颗粒燃料成型品质的影响；在湿度12%、粉碎机筛眼直径2mm、温度100℃的条件下，研究了压力为1.5、3、4.5、6、7.5kN 下对以上3种生物质颗粒燃料成型品质的影响；最后，通过对3种生物质颗粒燃料成型后的密度与径向抗压力进行对比分析，找到3种生物质颗粒材料成型品质达到最佳时所需的温度和压力，为不同生物质颗粒燃料的生产提供参考。
