If the chemical reactivityofcoal is strong, the gasification reaction temperature will be relatively low and the gas outlet temperatures will also be lower.
气化化学反应活性较强的煤，气化反应温度相对较低，其正常炉出煤气温度也相应较低。

The research show that the content of disordered carbon is a good index of the reactivityofcoal and coal char, correlates with ignition characters very well.
结果表明：无序碳含量是衡量煤和煤焦活性的一个很好的指标，它与着火特性有很好的关联性；

Reactivity value was further turned into reactivity index T15by mathematics method which can reflect quantity of combustible volatile in coal.
