What is the operation process of a low nitrogen burner?
The maintenance of low nitrogen burners is very convenient, and the mixing device can be directly removed without the need to remove the burner from the boiler, which can adapt to any type of combustion chamber. What is the operation process of a low nitrogen burner?
As long as you understand the operation engineering of low nitrogen burners, you can repair and troubleshoot the combustion engine when it malfunctions. Introduction to the operating process of a combustion engine/incinerator. Taking a compound proportion gas combustion engine as an example, its operating process has four stages: preparation stage, pre blowing stage, incineration stage, and normal incineration stage.
In the preparation stage of the low nitrogen burner, after the program control machine is powered on, the internal program self check begins, and the servo motor drives the air door to the closed state. After the program self checks, it is in standby mode. When the temperature controller, ultra-low pressure switch, steam boiler steam pressure switch and other constraint switches are activated, the program control machine starts to start and enters the pre blowing stage.
If the solenoid valve of the low nitrogen burner is equipped with a leakage detection system, when the above constraint switch is approved, the system will first detect the leakage of the valve, and after passing the detection, it will enter the pre blowing stage. In the pre blowing stage, the servo motor drives the air door to the open state, starts the fan motor, starts supplying air for 13 seconds, and blows in air for pre blowing.
