Ash handling in hard coal and lignite-fired power plants. Reliable fly ash removal. The fly ash contained in the flue gas is normally removed in electrostatic precipitators (ESPs) or baghouse filters. Depending on the level of unburnt carbon and other residues, the collected fly ash is used as a raw material for the cement industry. The fly ash is sorted depending on the unburnt
