摘　　要：从生物质燃料的灰熔融性和热值两个关键性的特性指标着手,以玉米秸秆和水稻稻壳作为主要原料,用试验优化设计和分析的方法 ,寻求混合生物质颗粒燃料的优化配方,提高混合生物质颗粒的软化温度ST>1 400℃,有效地解决了玉米秸秆颗粒结渣问题。对混合生物质颗粒进行了热重试验研究和燃烧机理、动力学特性分析,结果表明:混合生物质颗粒具有易着火和单峰值热解特性,燃烧性能良好。此研究为改善单一成分生物质燃料的燃烧性能,推广利用生物质能提供指导性建议。The purpose of this study is to optimize the raw material composition of biomass pellets from cornstalk and rice husk by means of experimental optimization design and analysis, based on two key targets of ash melting characteristic and heat value. The optimum residue mixtures heighten the softening temperature over 1 400 ℃, which effectively improves the ashresidue properties of cornstalk pellets. Several types of analysis have been investigated in the paper by thermo-gravimetric experiment, combustion mechanism and dynamic characteristic for composite biomass pellets. the results show that composite biomass pellets are apt to ignite and have better performance of single peak pyrolysis and combustion characteristic. The results obtained here can be very useful for biomass fuel to improve the combustion characteristic, and can direct further development and application of biomass energy.
