Non coking coal with a CV in the range of 6500 kcal/kg to 7000 kcal/kg is a preferred coal in these rerolling mills for the combustion in the reheating furnace. In coal fired reheating furnace, besides CV of the coal, other factors which are important include (i) ash, moisture, and the volatile matter contents of the coal, (ii) consistency of ...
Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill "puffs". Explosions in a pulverized coal system are normally called "puffs.". A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.

Coal Mills are the Heart of a Coal Fired Plant Maximum capacity, reliability and performance of your operation rely on the critical roles that your coal mills perform: Conditioning coal for proper combustion. (Fineness, fuel distribution, throughput) Delivering 100% of fuel to the boiler.
The four most common coal pulverizers types are: BallTube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills.

Each rolling stand consists of a top and a bottom roll, driven through a gearbox by an electric motor. The rolls of the stands have contours or "grooves" machined into the rolls, so that the hot billet passing between the grooves is reduced in size and shaped by each subsequent stand. Typical motor sizes for modern mills is 600kW to 1200kW ...
Operation. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles. The primary air flow to the furnace is fed through the mill, with the purpose of heating and lift the coal particles out ...
