Coal Ash Basics | Coal Ash (Coal Combustion Residuals, or CCR

Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coal-fired power plants. Coal ash includes a number of by-products produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler.

Pulverised Coal - an overview | ScienceDirect Topics

For chain and sloping grate systems, fuel is fed into a feed chute and dragged onto the grate. For units burning wood, a typical design uses a “windswept spout,” where the combustion air injects the fuel above the bed and the fuel falls onto the bed. For units burning coal, a “paddle wheel” type of feeder puts the fuel onto the grate.
