摘  要:采用热重分析仪对油页岩半焦与不同煤化程度的煤混合燃烧特性进行动态分析,讨论了掺混煤种和比例对燃烧过程的影响.结果表明,燃烧特性好的煤种可以改善页岩半焦燃烧特性,额吉长焰煤是最佳掺混煤种,随着煤掺混比例的提高,混合物燃烧特性指数增大.Thermal analysis and combustion characteristics of mixture of oil shale semicoke and coal investigated on TG analyzer, with regard to comparing the process of the mixture with those of the individual components. Meanwhile, the effect of rank of coalification and the rate of coal, which was mixed into the oil shale semi-coke, was studied. Results show that: the combustion characteristics can be improved by mixing coal with good combustion performance; the mixture of oil shale semi-coke and Erji jet coal had better combustion performance than other mixtures; the index of combustion performance of the mixture increased with the augment of the proportions of EJ coal.
