Therefore, it can be concluded that DTF reactor is more appropriate to be used for investigating high temperature gasification reactivity of coal char.

If the chemical reactivity of coal 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。
