Fly Ash Conveying System

The fly ash is pneumatically transported from collection hopper of economiser, air-preheater and electrostatic precipitator (ESP) to storage silo for subsequent transport by trucks.Fly ash is produced by coal-fired electric and steam generating plants. Typically, coal is pulverized and blown with air into the boiler's combustion chamber where it immediately ignites, generating heat and producing a molten mineral residue.Ash conveyors are devices that help move ash from one system to the next. The most common of these conveyors use a giant screw inside a tube. One end of the tube is inside the ash that needs to move. As the screw turns, it pulls the material up from the pile and traps it between its teeth.
