Precautions for commissioning and maintenance of gas turbines

1. When the secondary ignition procedure of the gas burner fails continuously, it should be stopped to check whether the gas supply system of the burner is normal and whether the circuit connection is correct. The burner can be restarted only after the fault is removed.

2. The gas supply pipeline is strictly prohibited to be tapped or rubbed with a wrench or metal rod to avoid static electricity or sparks and gas explosion.

3. It is strictly forbidden to smoke, weld, cut and other illegal operations in the air supply valve group or the flange surface of the pipeline. 4. It is strictly forbidden to conduct any open flame test beside the pipeline, valve group and pressure regulating valve to avoid major accidents.

5. Test whether there is fuel in the gas supply line, usually with a gas low pressure gauge. 6. In the gas supply pipeline, it has been emptied, but there are residual gas or liquid droplets on the pipe wall, which will also cause combustion and explosion in case of 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 end 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 emptied, and then the valve group can be disassembled and repaired.

8. In the commissioning work, the gas must be serious, safe and efficient.

9. It is forbidden to use non-explosion-proof electric power tools on site.

10. Before using the VPS504 leak detection device, the valve block cover must be checked.

11. It is recommended to use VPS504 leak detection device for burners of 600,000 kcal and above. If the user does not match it, the customer will be responsible for the accident.
