The main categories of ash are bottom ash, fly ash, mill reject ash. Bottom ash, which accumulate at the bottom of the boiler in the form of lumps, requires mechanical, pneumatic conveying or hydraulic handling systems. Fly ash, which is more volatile, gets deposited at the bottom of the ash hoppers in the equipment downstream of the boiler.
