Fly ash handling systems

Fly ash is generated in fuel combustion process. Its particle size is fine and therefore it rises in the boiler with the hot air. It’s important to collect and process the ash so that it doesn’t enter in the atmosphere and nature. Nowadays, air pollution control standards require fly ash handling.

conveying systems for fly ash

Fly ash handling systems are part of Laitex’s full scope solutions. We have delivered a variety of systems around the world, regardless of size, boiler type and fuel.

Fly ash conveying and fly ash silos

Often in small power plants collect fly ash on the same conveyors as bottom ash. This way, the same conveyor system can handle both bottom and fly ash. Fly ash goes through same, screening and storage process as bottom ash.

If fly ash is collected separately, it is often done with a different type of filters, cyclons and an ESP (electrostatic precipitator) equipment. ESP is the last separator in the line which separates even the finest particles from flue gases.

Fly ash is cooled and conveyed to a fly ash silo by conveyors or pneumatic conveyors. The ash is transported from the silo by trucks to further processing. Almost half of the fly ash produced can be recycled to be used in for example cement or plaster.
