Bottom Ash an overview ScienceDirect Topics

2.13 Coal bottom ash. CBA or BA is an incombustible product of unburned coal from the combustion process of coal. It is produced in coal-operated thermal power plants at the bottom part of the coal-fired furnace, where the coarser pieces are gathered. Many coal-operated power plants have this perennial problem of piling up of CBA, and thusget price
