Bottom ash is a larger particle size then fly ash and is a heavier waste that resembles a mix of sand and small rocks. Just over 10% of coal combustion waste is bottom ash. Boiler slag is made when bottom ash melts under the intense heat of combustion. Boiler slag resembles the size of gravel.Power Boiler Ash Handling TrainingMany power boilers burn solid fuels such as wood residue or biomass and coal, which produce large amounts of ash that must be handled and disposed of. Each solid fuel boiler has a specially designed system to safely remove, transport, and dispose of the ash generated during operation of the boiler.
