Coal HGI > 120 is classified as extremely soft and includes only some types of brown coal (Tichanek, 2008). Regardless of any specific correlation between grindability and maceral type, it is clear that some macerals are more difficult to grind than others. This results in a coal pulverizer generating a size range of particles with a general ...

These proportions depend on the polydispersity number n, which is mainly connected with the classifier design and also with the type of pulveriser. In typical installations for coal n = 0.8 - 1.2, where the lower values correspond to high-speed pulverisers (e.g. fan mills), while the higher numbers correspond to the medium- and low-speed mills.

Depending on speed pulverizers are classified as low-speed, medium-speed, and high-speed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuel-firing systems: bin system and direct-firing system. Coal feeders are either the volumetric or gravimetric type.

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.
