Carbonizing furnace, as a high-temperature treatment equipment, is widely used in the carbonization of wood, bamboo and other materials. Due to its long-term operation in high temperature and high pressure environment, it is inevitable that various failures will occur. The following are some common faults in the operation of carbonizer and their solutions.

1. Abnormal temperature

Fault symptom: The temperature in carbonizing furnace is too high or too low to meet the set requirements.

Possible causes: Temperature control system failure, heating element damage, thermocouple failure.

Solution: Check whether the thermostat works normally, and replace the damaged parts if necessary; Regularly calibrate thermocouples to ensure accurate data; Check whether the heating element is aging or broken, and replace it in time.

2. The furnace body is poorly sealed.

Fault symptom: Gas leakage in the furnace leads to poor carbonization effect or increased energy consumption.

Possible causes: Aging sealing strip, lax door closure, cracking of welding parts.

Solution: Check the integrity of the sealing strip regularly and replace it in time if it is found to be aging; Adjust the oven door fastening device to ensure tight closure; Repair or re-weld the welded parts.

3. Uneven heating

Fault symptom: Decline of product quality.

Possible causes: Unreasonable arrangement of heating elements and failure of internal circulation system.

Solution: Optimize the layout of heating elements to ensure the uniform distribution of heat; Check whether the circulating fan or airflow guide device is running normally, and maintain or replace it if necessary.

4. Electrical system failure

Fault symptom: The control panel is inoperable or an abnormal alarm appears.

Possible causes: Short circuit, loose wiring and damaged controller.

Solution: Check whether the circuit connection is firm and whether there is short circuit or open circuit; Diagnose the controller and replace it with a new controller if necessary.

5. Furnace corrosion

Fault symptom: Corrosion or corrosion perforation appears on the inner wall of the furnace body.

Possible cause: The corrosion of furnace body by chemical gas in high temperature environment.

Solution: Choose corrosion-resistant materials to make the furnace body; Regularly clean the residues in the furnace to reduce the accumulation of corrosive substances.

In order to ensure the normal operation of carbonizer and prolong the service life of equipment, daily maintenance and regular overhaul are very important. Operators should be familiar with equipment performance, find problems in time and take effective measures. At the same time, strengthening the maintenance of key components can effectively reduce the occurrence of faults and improve production efficiency.
