摘要：The paper discusses intermittent gas preparation operation ideas of fixed bed gasifier from three aspects, that is two-balance, three-seven content, four uniform. And it briefly expounds strengthening process management from above three aspects, only do this can realize gas-making importance, that is stability coal bed, blast capacity, pressure, steam pressure, gasification layer thickness.%介绍从“两大平衡”、“三七”内容、“四个统一”三个方面对固定层煤气发生炉间歇制气的操作思路进行了探讨，并简要阐述了从以上三个方面入手加强造气的工艺管理，才能实现造气生产的“炭层稳定、风压风量稳定、蒸汽压力稳定及气化层厚度稳定”的重要性。
