Coal is a sedimentary rock that is blackish or brownishblack in colour and is developed from start rock also referred to as coal seams. This is assumed to have developed from the residue of the algae plants. Coal is composed of a maximum amount of carbon with other organic elements chiefly hydrogen followed by sulphur, oxygen, and nitrogen.

Coal flowing around a bend will flow heavy on the outside corner of the bend, and in a horizontal run it will be heavy on the bottom of the pipe. Coal sampling data collected in a bend or on a horizontal run will not be representative.

How a Coal Plant Works. 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. Here's a real ...
