1. Regularly clean dust and carbon deposits from the heat exchanger surface to maintain good heat transfer efficiency.
2. Check if the fan operates smoothly and if the bearings require lubrication.
3. Clean or replace the inlet air filter to prevent dust blockage from affecting airflow.
4. For combustion-type hot blast furnaces, regularly check the burner condition and clean carbon deposits from the nozzles to ensure complete fuel combustion.
5. Check that all sensor and controller wiring is secure to avoid control malfunctions due to poor contact.
6. When not in use for an extended period, disconnect the power, gas, or fuel supply, thoroughly clean the interior of the equipment, and take rust prevention measures.
