摘要
利用热重分析仪制取了生物质秸秆与煤不同混合比时的焦炭,并对焦炭的燃烧特性进行了研究。结果表明,掺入生物质促进了煤的焦炭的燃烧,但混合物焦炭的燃烧速率与生物质掺混比呈非线性关系。分析产生上述现象的原因主要是生物质焦炭和煤焦炭燃烧速率的差异和它们夺氧能力差异共同作用的结果。
The Charcoal of biomass stalk-coal mixtures at different mass fractions were obtained by thermogravimetry analyzer, and its combustion characteristics was studied. The results show that biomass can improve the combustion characteristics of charcoal formed by coal, but the combustion rate of the charcoal formed by the biomass-coal mixture is not in nonlinear relationship with the biomass mass fraction. It is suggested that it is caused by the difference of the combustion rate and oxygen consumption rate between biomass charcoal and coal charcoal.
