Pulverization of coal is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.

The fundamental principle behind coal power plants is the combustion process. Coal is pulverized into a fine powder, often as small as talcum, to maximize its surface area. This finely ground coal is then blown into a combustion chamber, along with a stream of air. The heat generated by combusting the coal transforms water into …
