磨煤制粉系统是火力发电厂燃煤锅炉主要系统之一,其运行的可靠性和经济性关系到机组的安全经济性。新中国成立以来,由于受传统设计思想的影响和设备制造条件的限制,国内燃煤电厂大多采用滚筒式低速钢球磨煤机中间贮仓式制粉系统,实践证明,这种设计偏于保守,经济效益不高。近几年,自国外引进了多种大型滚压式中速磨煤机,并取得了一定的运行经验,现已有条件按照安全经济的原则进行总结,选择出适合于我国煤源特点的各种大型磨煤机,以设 Pulverized coal milling system is one of the main systems of coal-fired boilers in thermal power plants. The reliability and economy of operation depend on the safety and economy of units. Since the founding of New China, due to the influence of traditional design ideas and equipment manufacturing conditions, the domestic coal-fired power plants mostly adopt the intermediate silo milling system of drum-type low speed ball mill. Practice has proved that this design is conservative, Economic efficiency is not high. In recent years, introduced a large number of large-scale rolling medium-speed mill from abroad, and has gained some operational experience, conditions are now available in accordance with the principle of safety and economy to summarize, select suitable for the characteristics of China’s coal resources Large coal mill to set
