How does a coalfired boiler work?

How does a coalfired boiler work?

By Perrine Juillion / June 25, 2019. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

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 ...

Coal is a nonrenewable resource we will eventually use it all, so we cannot rely on it for a long term energy source, especially at the rate we are currently consuming it. When coal is burned it pollutes the air. Greenhouse gasses produced cause global warming and toxins released by burning coal can harm people and the environment.
