摘要
应用TG-DTG热重分析方法研究分析煤与生物质的混合燃烧过程,考查了生物质占比、O2浓度、升温速率对煤与生物质混合燃烧特性参数的影响。结果表明,生物质掺入煤中可以改良原煤的燃烧性能,增加生物质占比、O2浓度、升温速率都可以改善煤的着火性能、燃尽性能及综合燃烧性能,有助于燃烧的进行。
The combustion process of coal and biomass mixture was analyzed by application of TG-DTG thermogravimetric analysis,and the influence of biomass addition ratio,O2 concentration and heating rate on combustion characteristic parameter were investigated.The results show that the combustion performance of raw coal can be improved by adding biomass into coal,and increasing the addition ratio of biomass,heating rate and oxygen concentration can improve the ignition performance,burnout performance and comprehensive combustion performance of the coal and biomass mixture,helps with the combustion process.
