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.

Fly Ash. Fly Ash is a byproduct of coalfired electric generating plants. The coal is pulverized and blown into burning chambers for immediate combustion. Heavier ash particles (bottom ash or slag) fall to the bottom of the burning chamber and the lighter ash particles (Fly Ash) fly out with the exhaust gas, thus the term Fly Ash.
