Typical maintenance costs and intervals for each pulverizer gearbox were as follows Oil changes required every 12 months at a cost of $5,000 in material and labor and $20,000 to $50,000 in lost electrical production, typical of most coal fired power generation units of this timeframe. This particular plant had 13 of these coal pulverizers.Figure 1 Coal fired Power Plant. Process. Coal is transported to the coal bin by use of a conveyer from the coal stock piles or rail car unloading stations. From the coal bin, the coal is fed into the coal pulverizer and dried using ~300 F air . When coal is pulverized, the process grinds the coal into a fine dust which expands the coal’s.
