自80年代初宝钢自备电厂350MW机组全套引进了RP型中速磨煤机设备以来,河南姚孟、山东黄台、石横、福建福州、安徽平圩、浙江北仑港、上海石洞口第二等新建或扩建的大型燃煤火力发电厂均相继采用了此类磨煤机,比重日益增加。RP型磨煤机的单位功耗7～8kWh/t煤左右,大大低于钢球磨煤机的单位功耗,随着对节能降耗的重视,RP型磨煤机已越来越引起人们的注意。现将RP型磨煤机在宝钢自备电厂运行十余年出现的主要问题及对策介绍如下。
Since the early 80s 350 MW Baosteel Power Plant unit has introduced a full set of RP type medium-speed mill equipment, Henan Yao Meng, Shandong Huangtai, Shi Heng, Fujian Fuzhou, Anhui Ping Wei, Zhejiang Beilun Port, Shanghai Shidongkou second Such new or expanded coal-fired power plants have been using such coal mills, the proportion of increasing. RP unit coal mill unit power consumption of about 7 ~ 8kWh / t, much lower than the ball mill unit of power consumption, with the focus on energy saving, RP mill has caused more and more people note. Now RP mill in Baosteel owned power plant operation more than ten years the main problems and countermeasures are described below.
