Bottom Ash - an overview | ScienceDirect Topics

Boiler ash comes from the suspended particles in exhaust gas and then drops into the flue-dust retainer as blocked by boiler tube. It can be gathered alone or with bottom ash. Fly ash is the fine particles gathered by the fume cleaning system, predominantly the baghouse, and may contain CaCl 2, CaSO 4, Ca(OH) 2, active carbon, and most importantly, dioxins and soluble heavy metals.
