采用氧弹法等方法对2种典型煤(XJ煤和QJY煤)热值进行了测量。采用热重试验法对试验煤样的燃烧放热特性进行了研究。计算并对比分析不同煤样的热释放速率。2种煤对比可知,XJ煤在较低温度水平时即可集中释放大量热,QJY煤在较高的温度水平较为长时间地平均地放出大量热。
The calorific values of two kinds of typical coal (XJ coal and QJY coal) were measured by oxygen bomb method. Thermal gravimetric method was used to study the combustion and exothermic properties of coal samples. Calculate and compare the heat release rate of different coal samples. The comparison of 2 kinds of coal shows that XJ coal can release a large amount of heat intensively at a lower temperature level, and QJY coal emits a large amount of heat at an even higher temperature level for a long time.
