淮南发电厂~#3、4炉为400吨/时超高压中间再热锅炉,配置了两台DEM380/550双锥型球磨机的中间储仓制制粉系统,排粉机为Mg-27-11No-16.5D型。该制粉系统自投产以来,虽经调试,但制粉电耗一直较高,在32～33度/吨煤的水平,降不下来,其主要原因在于系统阻力较大,粗粉分离器效率低以及排粉机选型偏大等。 Huainan Power Plant ~ # 3,4 furnace 400 tons / hour EHV intermediate reheat boiler, equipped with two DEM380 / 550 double cone ball mill in the middle of the system for the production of flour system, powder machine Mg-27-11No -16.5D type. Although the commissioning of the milling system has been put into operation, the power consumption of pulverizing has been relatively high at the level of 32-33 degrees / ton of coal. The main reason is that the system resistance is large and the efficiency of the coarse powder separator Low as well as large selection of powder machine and so on.
