The on-line ash cleaning device is suitable for the tubular horizontal on-line air preheater in the furnace. It consists of comb-shaped ash cleaning elements and supporting rods through special parts. The driving rod is installed to drive the dust removal element to reciprocate in the gap between the tubes of the air preheater, and the dust removal frequency can be set to10min, 20min and 40min to prevent fly ash from accumulating on the air preheater, thus achieving the purpose of dust removal.
The on-line ash cleaning device can be used for on-line ash cleaning without stopping the boiler, which is automatically controlled by PLC and can be remotely connected to the boiler DCS system.
