How to solve gas burner debugging problems? Teach you step by step how to debug the burner!
Things to note when debugging and repairing gas burners:
(1). When the gas burner continuously fails the secondary ignition program, it should be stopped to check whether the gas supply system of the burner is normal and whether the circuit connections are correct. The burner can be restarted only after the fault is resolved.
(2). It is strictly forbidden to knock or rub the gas supply pipeline with a wrench or metal rod to avoid causing static electricity or sparks, which may lead to a gas explosion.
(3)． Smoking, welding, cutting and other illegal operations are strictly prohibited on the gas supply valve block or pipe flange surface.
(4)． It is strictly prohibited to conduct any open flame test near pipelines, valve groups and pressure regulating valves to avoid major accidents.
(5)． To test whether there is fuel in the gas supply pipeline, usually use a gas low pressure gauge to test.
(6)． In the gas supply pipeline, even if it has been drained, but there are residual gas or liquid droplets on the pipe wall, it will also cause combustion and explosion if it encounters static sparks and open flames.
(7)． When the gas supply pipeline is ventilated and the valve group is faulty, it needs to be disassembled. First, the main valve at the front of the valve group must be cut off, and then the gas in the pipeline from the main valve to the valve group must be evacuated, and then the valve group can be disassembled and repaired.
(8). In debugging work, gas must be done carefully, safely and efficiently.
(9). It is prohibited to use non-explosion-proof electrical power tools on site.
(10)． Before using the VPS504 leak detection device, you must check whether the valve group head is covered.
(11)． It is recommended to use the VPS504 leak detection device for burners of 600,000 kcal and above. If the user does not fit it, the user will be responsible for any accidents caused.
(12)． Before starting the burner, the air supply pressure must be tested to check whether there is any leakage. After confirming that it is normal, simulate the operation again.
(13)． Explain safe operation precautions to customers in detail.
(14)． When the burner is not in use, inform the customer to cut off the main gas supply valve and main power switch.
(15)． It is recommended not to debug the gas engine at night.
(16)． At the end of debugging, it is necessary to organize operators to conduct training on the use of operating directions, and establish operating procedures if necessary.
The above are just some common methods and matters. Specific matters will be solved according to specific methods.
If it is an ignition failure, how to judge it? First, start the burner three times in a row. If there is no ignition and combustion, it is judged as an ignition failure, and corresponding inspections are required to eliminate the fault. The fan operates normally during ignition and the program is correct.
1. If the gas source fails, check whether the natural gas pressure is maintained at 3-5kpa. If it is too high or too low, it will cause misfire. Solution (adjust natural gas pressure regulation and set pressure).
2. If the damper is faulty, check the size of the damper. If the damper is too large, it is prone to multiple misfires. The solution is as follows: (Turn the damper down appropriately, but do not close it completely).
3. If the ignition electrode or ignition transformer fails, the ignition transformer does not ignite, or the ignition electrode is too dirty and is in the wrong position, an ignition failure will occur. Solution (test whether the ignition transformer is igniting, clean the ignition electrode, and adjust the ignition gap to maintain 2-3mm).
