Bottom ash. Bottom ash is most commonly conveyed in a hydraulic system in which the ash is entrained in a high flow, circulating water system and delivered to either an ash pond or to a remote dewatering device. Alternatively, mechanical drag systems have been used to convey bottom ash to the dewatering storage bin because they use less water and usually have a lower initial cost.

Boiler tubes extract heat from the boiler, cooling the flue gas and causing the residue to harden into ash. About 10% of the particles are coarse ash – also known as bottom ash or slag – that falls to the bottom of the combustion chamber. The remaining 90% are tiny particles that remain suspended in the flue gas. These become the fly ash.
