摘要
利用TG-DTG热分析技术对煤、生物质及二者混合物的燃烧过程进行分析,研究了煤种、生物质、生物质添加比例、升温速率及氧气流量等因素对燃烧特性的影响.结果表明,生物质的着火特性、燃尽特性和燃烧性能明显优于原煤;添加生物质可以改善原煤的燃烧特性,随着生物质添加量的增加,燃烧性能改善越显著;升温速率增加,着火特性指数和综合燃烧特性指数升高,燃尽性能降低;增加氧气流量,可以显著改善燃料的燃烧性能.
The TG-DTG thermal analysis technology was applied to analyze the combustion process of the coal, biomass and their mixture, and the influence of coal kinds, biomass kinds, biomass addition ratio, heating rate, oxygen flowing rate to the combustion characteristic of mixture was also studied. The results show that the biomass＇s ignition, burnout and combustion characteristics are better than the coal＇ s. Biomass can improve the combustion characteristics of coal. With the increase of the biomass addition, the combustion characteristics improve more obviously. With the increase of heating rate, the ignition characteristic parameters and combustion characteristic parameters are increased, while burnout characteristic is reduced. With the increase of oxygen flowing rate, the combustion performances of flue can be improved.
