• Coal Mills in Thermal Power Plant | PDF | Mill (Grinding)

    Coal is ground and is directly carried from the Pulveriser to the Furnace by use of Pressurised air. Pressurised Air from Primary Air Fans goes to the Pulverisers. Sufficient temperature is maintained for drying of coal and moving to the furnace without settling. INDIRECT FIRING: Here coal is ground and is carried to an Intermediate Bunker.

     · Primary air enters coal mill, and the pulverized coal is blown into classifier when it is dried. The fine pulverized coal is sent to boiler for combustion, and the coarser falls into coal chute to continue grinding ( Niemczyk et al., 2012 ). The establishment of coal mill operation balance is based on the following assumptions:

  • What Is Coal Power Plant and How Does it Work?

     · Coal that has been ground into a fine powder by a pulverize is blown into a furnacelike device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam. The highpressure steam turns the blades of a turbine, which is connected by a shaft to a generator.

    The pulverized fuel is injected horizontally into the furnace with a high degree of turbulent swirl to promote rapid combustion. Like downshot firing, each burner produces an individual and independent flame zone. This means that the correct amount of secondary air must be supplied to each burner to ensure proper combustion in each flame zone.
