淮南发电厂10号炉系上海锅炉厂生产的65吨/时机播链条炉,1961年投入运行,1965年改为70吨/时煤粉炉,具有钢球磨贮仓式制粉系统,设计煤种为淮南望峰岗洗中煤(A~g=26.4%,V~r=39%,Q_d~g=4689大卡/公斤)。该炉正常运行中掺烧邻炉的6台151型中速碗式磨煤机排出的矸石,占总燃煤量的10~15%,加上球磨机铸铁球耗损较大,同时高温级省煤器处烟气流速较高,因此该级蛇形管磨损较严重。特别是1970年7月提高出力至90吨/时运行后,磨损更为加剧。
Huainan Power Plant No. 10 furnace Shanghai Boiler Factory production of 65 tons / hour sowing chain furnace, put into operation in 1961, 1965 to 70 tons / h pulverized coal pulverizer, with a ball mill silo milling system, the design of coal Huainan Wangfeng Gang washing coal (A ~ g = 26.4%, V ~ r = 39%, Q_d ~ g = 4689 kcal / kg). In the normal operation of the furnace, 6 sets of 151 type medium speed bowl coal mills with adjacent ovens were burned, accounting for 10 to 15% of the total amount of coal burned. In addition, the abrasion of cast iron ball of the ball mill was large, Flue gas flow rate is high, so the level of serpentine wear more serious. Especially in July 1970 increased output to 90 tons / hour operation, the wear and tear even worse.
