Function Of Various Parts Of Air Supply System Of Low Nitrogen Burner
During the use of low nitrogen burner, the air supply system can send air with a certain wind speed and volume to the combustion chamber, which has an important impact on the combustion effect of the equipment. It is generally composed of the shell, fan motor, fan impeller, air gun fire tube, damper controller, damper baffle, diffusion plate, etc. The functions of these seven components are described below.
1. Shell: it is the main component of the mounting bracket of various components of the burner and the fresh air inlet channel.
2. Fan motor: it mainly provides power for the operation of fan impeller and high-pressure oil pump. Some burners also use a separate motor to provide power for the oil pump. The motor is generally 2800 rpm.
3. Fan impeller: generate enough air pressure through high-speed rotation to overcome furnace resistance and chimney resistance, and blow enough air into the combustion chamber to meet the needs of combustion.
4. Air gun and fire tube: it can guide the air flow and stabilize the air pressure.
5. Damper controller: It is a driving device that controls the rotation of damper plate through mechanical linkage.
6. Damper plate: It is mainly used to adjust the size of the air inlet channel to control the air inlet volume.
7. Diffusion disk: also known as flame stabilizing disk, its special structure can produce rotary airflow, which is conducive to the full mixing of air and fuel, and also plays a role in regulating the secondary air volume.
From the introduction of the functions of various parts in the air supply system of low nitrogen burners, we can know that fans also play a vital role in the working process of such combustion equipment. It can even be said that the air supply function of the air supply system is mainly completed through fans. Therefore, we should take it seriously when selecting the fan configuration of the equipment.
