摘要
通过热重分析得到了生物质秸秆与煤混燃的反应动力学参数,分析认为,生物质的掺混能够改善煤的燃烧性能,主要体现在热解(挥发分析出)阶段,在焦炭的燃烧阶段没有明显体现;不同混合比对混合燃料燃烧性能的影响因素不同,在掺混比例较小时,主要是降低燃料的活化能,在掺混比例较大时,主要是增大反应的频率因子。
Reaction kinetics parameters of the mixture of coal and biomass stalk were obtained by thermogravimetry analyzing. The parameters show that biomass mixed is good for improving combustion characteristics of coal. There is obvious effect during pyrolysis,but not during charcoal combustion. The influence factors are different at different biomass mass fraction. When it is smaller,the main factor is decreasing activation energy of the mixture and it is increasing frequency factor of reaction when bigger.
