Coal can be used in the production of thermal power. Then this thermal helps further to produce electricity. In this process, coal has to be transformed into powder form. The powdered coal is now heated at a very high temperature to turn water into steam. Electricity is generated when the steam turns turbines at high speed. 4. Cement

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 ...
