摘　　要：现行电厂运行中,启动磨煤机要求投用油枪助燃以提供足够的点火能量,这在磨煤机频繁启动时将消耗比较多的燃油。为降低锅炉燃油消耗量,达到节能的目的,某电厂进行了不同负荷下不投油启动磨煤机的试验,结果表明,当机组负荷大于180 MW时,不投油启动磨煤机是可行的。Nowadays, most power plants need igniting oil guns to provide enough firing energy tor pulverized coal comhustion when starting a mill. Thus, it will consume much fuel oil when starting mills frequently. In order to reduce the oil consumption and save energy, experiments on starting mills without oil on different unit load levels have been done in a power plant. Results show that it is feasible to start one coal mill without oil when the unit load is bigger than 180 MW.
