低挥发分无烟煤及其混煤燃烧性能研究

Study on combustion characteristics of low-grade anthracite coal and its mixed coal

采用热天平和一维火焰炉对耒阳低挥发分无烟煤及其混煤的着火、燃烧、燃尽以及结渣特性等进行试验研究,分析了挥发分含量及掺配比对煤燃烧性能的影响。根据试验结果,运用模糊数学方法进行综合评判,确定了混煤的最佳掺配比,为混煤的合理燃烧提供了科学依据。

This article investigates the characteristic of ignition, combustion, burn out and slag formation about lowgrade anthracite and its mixed coals in Leiyang. The influence of volatile component and mixed-proportion for coal combustion is analyzed. Based on the test result, the optimized mixed-proportion is decided by blur algebra method, providing scientieal foundation to reasonable combustion of mixed coal.
