Ash Handling Systems(Bottom Ash, Fly Ash
An ash handling system collects and transports the bottom ash and the fly ash generated in coal fired thermal power plants to an ash pond or ash storage silo. There are two types of bottom ash handling system; wet handling system cooling by water and dry handling system cooling by air. The fly ash is used as a raw material for cement and an additive mixture for concrete while the bottom ash is recycled into bricks and aggregates as construction materials. Halla’s ash handling systems minimize environmental pollution and maximize the economical benefits from the extended recycling
