摘　　要：采用了TG—DTG—DTA联用的热分析技术,通过试验和分析了不同的热分析条件下,煤中黄铁矿在氧化过程中硫分析出的规律和燃烧特性;着重探讨了不同的黄铁矿重量、不同的升温速率和不同的掺比物对热分析逸出特性的影响。实验表明,不同的热分析条件对热分析的结果有一定的影响和规律。The focus of this paper is to examine the release characteristics and the influence of the pyrite in coal with the united technology of a controlledatmosphere programmedtemperature oxidation technique of TGDTGDTA thermal analysis. The release characteristics in different temperaturechange ratio, different sample weight and the mixed samples were examined. The results indicate that, in the temperatureprogrammed oxidation condition, the TGDTGDTA release characteristics of the pyrite in coal are changed with the different conditions.
