What is the operation process of low nitrogen burner?
The maintenance of the low nitrogen burner is very convenient. The mixing device can be directly removed without removing the burner from the boiler. It can adapt to any type of combustion chamber. What is the operation process of low nitrogen burner?
As long as you know the operation engineering of the low nitrogen burner, you can repair and remove the fault when the combustion engine breaks down. Introduction to the operation process of burner / incinerator take the complex proportion gas burner as an example. Its operation process includes four stages: preparation stage, pre purging stage, incineration stage and normal incineration stage.
In the preparation stage of low nitrogen burner, after the program control machine is powered on, the internal program self-test starts, and the servo motor drives the damper to the closed state. After program self-test, it is in standby state. When the temperature controller, the ultra-low pressure switch, the steam pressure switch of the steam boiler and other constraint switches are operated, the program controls the machine to start and enter the pre purging stage.
If the solenoid valve of the low nitrogen burner is equipped with a leakage detection system, when the above constraint switch agrees, the system will first detect the leakage of the valve and enter the pre purging stage after passing the detection. In the pre purging stage, the servo motor drives the damper to the firing state, starts the fan motor, starts air supply for 13 seconds, and blows air for pre purging.
