生物质与煤混燃的燃烧特性实验研究

Experiment to Co-combustion Characteristics of of Biomass and Coal

利用热重分析仪研究了冷压成型生物质麦秆与煤混燃的燃烧特性,实验中生物质质量掺混比分别取0%、10%、50%、90%、100%。实验结果表明,掺入生物质有助于改善煤的燃烧特性;随生物质质量掺混比的增加,燃料的着火温度和燃尽温度降低,可燃烧性指数、燃尽特性指数、综合燃烧特性指数提高。

Experimental studies on the combustion characteristics were conducted by the thermogravimetry analyzer for the pelletized wheat stalk biomass-coal mixture under various biomass mass fractions of 0.10% .50% ,90%.100%. The results show that it is good for improving combustion characteristics of coal that biomass is mixed. The ignition temperature and burning out temperature of the mixtures decrease with the increasing of biomass mass fraction, while combustibility index.burning out characteristics index and combustion characteristics index increase.
