The maintenance of the burner mainly includes the following aspects:

1. Function inspection: ensure that the burner can fire normally, and check whether the flame is stable, so as to evaluate the combustion efficiency.

2. Air tightness check: check the gas tightness of all gas lines to ensure no leakage. Clean or replace the gas filters to avoid them

Pressure-free drop.

3. Parts inspection: Check the key components such as electrode ceramic pipes, valves and pipes to ensure that they are in good condition.

4. Control system inspection: verify the working status of the air combustion proportional valve, check the opening and closing functions of the electrical connection and automatic control program 1.

5. Daily maintenance: keep the surface of the equipment clean, check the differential pressure gauge reading regularly, and flush the filter element when necessary.

6. Regular inspection: Regular inspection shall be carried out in strict accordance with relevant regulations, including wall thickness measurement and nondestructive testing, and the inspection results shall be recorded in the technical files.

7. Special circumstances: when there is pressure inside the equipment, any maintenance. For the maintenance under special circumstances, the relevant regulations shall be strictly observed.

Common problems and solutions to the burner:

Spray hole blockage: when troubleshooting, the control valve on the corresponding gas transmission line of the burner should be completely closed, and the fault should be removed before recovery.
