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.
Often in small power plants fly ash is collected 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. Depending on the situation, pneumatic conveyors that are completely impermeable are particularly suitable for transporting filter fly ash.
Fly ash is cooled and conveyed to a fly ash silo by mechanical 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.
Laitex designs and supplies fly ash handling systems that are customized based on customer’s needs. We create solutions for ash collection, conveying, handling, and storing. Our technology is suitable from small to large plants.
An important goal of Laitex is to create cleaner solutions for our customers around the world. Our mission motivates us to develop and create always better and more efficient devices. Laitex’s fly ash conveying equipment, storage silos and silo unloading equipment enable the flue gas cleaning systems to function properly and thus achieve the plant’s emission targets.
