Abnormal ash cleaning system: Damaged pulse valves, insufficient compressed air pressure, or excessive moisture in the compressed air.

Filter media clogging: Filter cartridges/bags have reached their service life, or the processed dust is highly humid and viscous, leading to clogging.

Improper ash cleaning program: Excessively long injection intervals result in incomplete ash cleaning.

Excessive dust load: The inlet dust concentration far exceeds the designed value.

Solutions: Check the air source and pulse valves, optimize the ash cleaning program, or replace with specially treated filter media such as oil-water resistant or PTFE membrane-coated types.
