There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

Pulverized coal combustion is a wellestablished technology that accounts for almost 97% of the world's coalfired power generation capacity [4]. Those units require the reduction of large size coal particles to a powdered form and carry the particles, using a carrier gas, into the combustion chamber (, furnaces and boilers).

The efficient burning of coal is a very dirty process to achieve the highest temperatures you use a "fluidized bed", that is, inject air into finely powdered coal. High temperatures = high efficiency. But you get lots of burning particles carried in the hot air stream. Keeping the flow velocity down you can let them turn harmlessly into ash ...
