What is boiler? It is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical …
Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise most coal pulverizers currently in service at pulverized coal power plants. The grinding rolls are stationary in this design, while a worm gear drive rotates the ring (commonly known as the bowl).

A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.

In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.
Answer (1 of 6): It is highly not recommended as seal air prevents coal dust powder to enter in bearing area. Thus running a mill without seal air would damage bearings. For protection, mills do have tripping on lower DP between seal air and primary air pressure. Not a good idea!
