Coal mills at the power plant crush the coal even smaller and dry it out. Giant fans blow the coal through tubes into the furnace, where it is ignited. Water is pumped from the San Juan River into a reservoir at the power plant. The water then goes through a treatment process that makes it cleaner than typical tap water.
Following a global trend away from coal as a source of energy production, by 2020, it was announced that all three of New Mexico's coal-fired power plants (CFPPs) were scheduled for retirement in the near future. Potential new owners of two of those CFPPs the San Juan Generating Station and the Escalante Power Plant – –
Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shock-resistant. NFPA requires coal mills to be good for 50 PSI.

Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
