摘要/Abstract

摘要： 采用热重分析法研究了水稻秸秆(RS)、煤粉(PC)及两者不同掺混比的混合物在不同升温速率下(10, 20, 40℃/min)从室温升至1000℃的燃烧特性，用Kissinger?Akahira?Sunose (KAS)法和Flynn?Wall?Ozawa (FWO)法计算了燃烧过程中的活化能。结果表明，失重速率(DTG)曲线中RS比PC多一个失重峰，且残余质量低。随升温速率增加，所有样品DTG曲线均向高温偏移，产生热滞后现象。RS和PC在混合燃烧过程中存在协同效应，且高温区域内更显著。PC掺混比例为50wt%时，混合物平均活化能的计算值较低，仅为76.0 kJ/mol (KAS)和83.2 kJ/mol (FWO)。
