摘　　要：在电厂燃煤机组中,一次风用于干燥和携带煤粉,并且直接关系到炉膛内的实际燃烧工况。某电厂1号锅炉磨煤机普遍存在低负荷时一次风压偏高的问题,经过深入分析,进行低负荷下的一次风优化工作,降低一次风量以最大限度地挖掘节能潜力,并收到显著效果。In the coal-fired generating unit, the primary air that was to dry and carry coal dust had effect on the burning operation mode in furnace. The problem was universal that the pressure of primary air was higher at the first mill in some plant, and the works of optimizing the primary air at low load condition and reducing the primary air flow to make sure the max-capacity of energy-saving were accomplished and obtained significant effect on the basis of deeply analysis.
