Decreased dust removal efficiency: This can be due to clogged filter bags with excessive dust accumulation. The solution is to clean or ｒｅｐｌａｃｅ the filter bags. If the filter bags are damaged, they should be replaced promptly. A malfunctioning ash cleaning system can also cause this issue. Checking and repairing the system can solve the problem.

Insufficient air volume: Fan breakdowns, blocked air ducts or air leakage are possible causes. Repair or ｒｅｐｌａｃｅ the faulty fan. Clear the blockages in the air ducts and seal any leakages to restore adequate air volume.

Excessive dust emission: Damaged filter bags or an improperly designed dust collector may be the culprits. Besides replacing the damaged bags, reevaluate and modify the collector's design if it's inadequate for the processing requirements. Correct operation parameters, such as adjusting the processing air volume, can also help.

Electrical failures: Control circuit malfunctions or motor damage can occur. Inspect and repair the control circuits or ｒｅｐｌａｃｅ the damaged motor to ensure normal operation.

Excessive ash accumulation in the ash hopper: A faulty ash discharging device like a clogged or non-functional ash discharge valve is often the reason. Unclog or repair the valve to allow for timely ash discharge.

Abnormal pressure: Blockages in the inlet and outlet air ducts or abnormal fan operation can lead to this. Clear the ducts and ensure the fan is working properly to stabilize the pressure.
