【摘要】 采用热分析法对煤热分解进行了试验研究，探讨了影响煤热解的因素，例如，煤粉粒度对热解产物的影响；温升速率对煤热解的影响等。研究了混煤的热解特性，提出了反映煤热解特性的煤粉热解产物释放特性指数。用热解反应动力学方程研究煤的热解过程，并以平顶山煤为例，将计算数值和试验数据进行了比较，结果基本一致更多还原

【Abstract】 This paper gives the property index,which can represent the pyrolytic property of pulverized coal and probes the factors affecting the pyrolysis of the pulverized coal,such as,the grain size of the pulverized coal,the heating velocity,etc.The paper also researches first the pyrolytic property of mixed coal.Index r is based on the results of a lot of pyrolysis tests with a computer thermal balance,then the pyrolysis process by the equation of solid pyrolysis reaction speed.With Pingdingshan coal as an example.The authors compare the calculated value with the test data and find they are basically the same.更多还原
