摘　　要：通过对煤粉气流爆燃产生的条件、爆燃后所产生的压力扰动等的分析,探讨磨煤机启停不投或少投油的安全性。同时,认为现行的磨煤机启停投油及其规程已不适应目前中大型直吹式墙式锅炉的磨煤机启动,并建议尽快建立与磨煤机启停不投油或少投油方式相适应的新规程。Through analysis of occurring condition for knocking combustion of pulverirized coal with air flow, and pressure disturbance produced after knocking combustion etc., the safety of startup and shutdown for coal pulverizer without injecting fuel oil or injecting little fuel oil has been discussed. At the same time, the recommendation has been made, pointing out that the injecting fuel oil during startup and shutdown of coal pulverizer, and the current code concerning stipulation in this aspect, have already been not suitable for largeand mediumscale direct wallfiring boilers.
