中文摘要：

以中小型钢铁企业应用最广的混合发生炉为载体，建立了煤气化数学模型。根据模型研究了通入的空气量、蒸汽量等操作因素对煤气化指标的影响。这对优化混合发生炉气化操作参数和实现中小型钢铁企业的高效煤气化具有重要的意义。

英文摘要：

The mixture generator which is widely used in small and medium steel companies is used as a cartier to establish a model of coal gasification. Based on the model the influence of gasification operation parmeters such as the steam volume, the air volume on gasification indices was studied. It is important for optimizing gasification operation parameters of the mixture generator and small and medium steel companies to achieve high efficiency gasification.
