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.
