摘　　要：采用热重分析法,对5种生物质与煤以相同比例掺混后在不同升温速率下进行了共燃试验。研究表明,生物质的加入改善了煤的燃烧性能,且随升温速率的升高,着火温度T2呈下降趋势;各试样的挥发分最大释放速率、固定炭最大燃烧速率、燃尽温度均呈增加趋势,它们的燃烧特性均随升温速率的升高而变好。The combustion behaviors of five different biomass samples,which mixed with coal in the same proportion which is 2：10,have been experimented with thermo-gravimetric analysis （TGA）method under different heating rates which are 10.20,30 ℃/min respectively.The results show that： the combustion characteristics of coal are improved by introduce of biomass.With the rise of heating rate, the maximum release rate of volatile and combustion rate of char, the burnout temperature and the combustible parameter increase, but the ignition temperature has decreased.
