Pulverizedcoal firing is especially suitable for very large boilers and cement kilns A wide range of coals can be burnt but coal preparation and gas cleaning are major cost items 70 75 μm is required for bituminous coals 80 for anthracite Coal dried with air at 250–350°C for milling in low medium or highspeed mills Main milling costs are power and replacement of worn partsGet Price
Nov 17 2012 · pulverizermill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill The coal flow is controlled by the feeder allowing coal to flow into the pulverizer mill The pulverized coal and air mixture is then transport to the boiler burner panelsGet Price

Typical maintenance costs and intervals for each pulverizer gearbox were as follows Oil changes required every 12 months at a cost of 5000 in material and labor and 20000 to 50000 in lost electrical production typical of most coalfired power generation units of this timeframe This particular plant had 13 of these coal pulverizersGet Price
3 The pulverizer always runs at its rated load irrespective of the load on the plant therefore its power consumption per ton of coal crushed per hour is less 4 Burners can be operated independently of the operation of coal preparation 5 The pulverizer can be shut down when sufficient reserve capacity hasGet Price
