宝钢电厂两台35万千瓦机组的锅炉配备三菱CE碗形磨煤机10台(每台出力为28.5吨/时)。自1982年5月并网以来,锅炉由于全烧煤,磨煤部件的磨损速度较快,特别是磨煤机的主要磨损件——辊套,使用了3700小时即要调换备品(日方介绍预想使用寿命为6000小时)。这样,不到一年,两台锅炉的磨煤机就要更换20多次,需要调换辊套60余只,并出 Baosteel Power Plant two 350,000 kilowatts of boilers equipped with Mitsubishi CE bowl mill 10 (each output of 28.5 tons / hour). Since the grid was opened in May 1982, the boiler has been worn out by coal and the wear rate of the coal grinding parts has been faster. In particular, the roller mill, which is the main wear part of the coal mill, has been used for 3700 hours to replace the spare parts Expected service life of 6000 hours). In this way, in less than a year, the two coal-fired boilers will have to be replaced more than 20 times and need to replace more than 60 roller sets
