Sep 30, 2018· Ash handling system are generally divided into three types fly ash handling system, bottom ash handling system and ash slurry disposal system. Fly ash handling system: Fly ash is captured and removed from the flue gases by economiser, airpreheater and electrostatic precipitator (ESP) located at the outlet of the furnace and before the induced ...
A. Dry Fly Ash Disposal system In dry disposal system, electrostatic precipitation (ESP) is the most popular and widely used method of emission control today which enables collection of dry Fly Ash. After collecting the Fly Ash in ESP, it is then transported by trucks or conveyors at the sight and disposed of by constructing a dry embankment.
