摘要
利用管式炉热重实验系统进行恒温下煤粉/生物质混燃实验。引入参数"可失重额余量",并提出"过燃份额"、"燃尽时间"、"稳定因子"、"参差指数"等参数,对不同掺混比、煤种及温度下的实验结果进行判定分析。结果表明:对于整个混燃失重过程,该判定方法不仅可定量化描述恒温条件下煤粉/生物质混燃特性,且能从反应前期与后期的失重分布差别的角度上深入探讨混燃效果。
The co-combustion of pulverized coal and biomass blends at constant temperature was carried out by thermogravimetry experimental system in tube furnace. The parameter ＇mass remain＇ was introduced, and the parameters ＇ overfire share＇ , ＇ burnout time＇ , ＇ steady factor＇ and ＇ uneven index＇ etc. were put forward to judge and analyze the experiment results in different blending ratios, coal types and temperatures. The results show that the judgment method not only can reflect the co-combustion characteristics of pulverized coal and biomass blends at constant temperature in weightlessness process, but also can investigate co-combustion effects based on the distribution difference of weightlessness between at earlier stage and at later stage of the whole weightlessness process.
