Thermal Power Guidelines for New Plants

Ash residues and the dust removed from ex-haust gases may contain significant levels of heavy metals and some organic compounds in addition to inert materials. Fly ash removed from exhaust gases makes up 60–85 of the coal ash residue in pulverized-coal boilers. Bottom ash includes slag and particles that are coarser and heavier than fly ash.
