Get PriceHere the coal is crushed and injected into swirling air in a cyclone. The liquefied ash collects on the walls of the cyclone and is drained away. For small steamgenerating units, stokers provide a slower, more stable combustion process. Lumps of coal are spread on a grate and burn in a flow of air passing through the grate.
Get PricePulverized Fuel Ash — Ash generated by burning of ground or pulverized or crushed coal or lignite fired boilers. It can be fly ash, bottom ash, pond ash or mound ash. Reactive Calcium Oxide (CaO) — That fraction of the calcium oxide which under normal hardening condition can form calcium silie hydrates or calcium aluminate hydrates.

Get Price· First the coal is crushed by preliminary crasher. The coal is crushed to cm. or less. Then this crushed coal is passed through a magnetic separator to separate any iron content from the coal. Iron must be removed, otherwise during pulverizing iron particles will cause spark which results in unwanted fire hazard.
