How Do You Pulverize Coal?
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. This leads to more fuel-efficient and easier-to-burn low-grade fuel sources.
This type of coal fineness increases the surface area for burning. This leads to an increased combustion rate and shelf life of the coal. Pulverized coal is typically used in power plants heated in fired furnaces.
Coal Pulverizers for Solid Fuel
Williams’ Vertical Roller Mill Pulverizers are perfect for coal and pet coke applications. These normally require fine to ultra-fine particle sizes for direct firing into boilers, kilns, and screen plates. This type of coal pulverizer mill uses centrifugal force to grind solid fuels while maintaining low operating costs.
