摘　　要：从理论到实际剖析了煤气炉内存在的吹风与制气、上吹与下吹、加炭与排渣三大矛盾和物料与碳平衡、热平衡、化学平衡三大平衡。介绍了它们对提高煤气炉的气化强度和降低煤耗的重要性。An analysis made from theory to practice of the three major contradictions, viz. , blow gas and gas generation, upward blow and downward blow and coke addition and slag discharge, and the three major equilibria., viz. , material and carbon equilibrium, thermal equilibrium and chemical equilibrium existing in coal gasifiers. An introduction is given to their importance in increasing the gasification intensity of coal gasifiers and reducing coal consumption.
