Coal is crushed to desired fineness between spheres or cylindrical rollers. After that, air from the boiler is heated to around 330°C (650°F). The raw coal is then fed into the pulverizer where it is ground into fine coal particles. What are the Advantages of Pulverized Coal? Pulverized coal produces a larger amount of heat than traditional coal.
