The burner (device) is one of the main components of the boiler. Its good or bad determines whether the boiler can effectively use the heat after fuel combustion, achieve rated output and operate safely, reliably and economically. Its function is to ensure that the fuel can be fully mixed when entering the furnace and ignite and burn steadily in time.

A well-performing fully automatic oil (gas) burner installed on a boiler still maintains its excellent combustion performance to a large extent, depending largely on whether the gas dynamics of both can match. Only when the boiler and burner are well matched can the burner's performance be fully utilized, ensuring stable combustion in the boiler furnace, achieving the expected heat output, and obtaining good thermal efficiency from the boiler. So, how should users select burners to maximize their performance?

In order to adapt to the needs of combustion process in the furnace and ensure the safe and economic operation of the boiler, the burner should have the following main technical performance:

1. High combustion efficiency is required

For fuel burners within a certain adjustment range, they should be able to atomize the fuel oil well, with fine and uniform droplets, appropriate atomization angles, and even distribution of oil mist along the circumference to increase the contact area between the oil mist and air. For gas burners at rated gas pressure, they should be able to pass through the rated gas volume and fully combust it to meet the production requirements of the boiler's rated thermal load.

2. Reasonable air distribution to ensure stable and complete combustion of fuel

The air necessary for combustion is supplied from the base of the torch, ensuring rapid and uniform mixing with the oil mist to guarantee complete combustion. The formation of harmful substances (such as CO and NOX) in the flue gas should be minimized. An appropriate recirculation zone should be formed in the airflow, placing the fuel and air in a higher temperature field to ensure rapid ignition and stable combustion.

3. The flame produced by combustion is adapted to the shape of the furnace structure

The flame produced should be well filled. The flame temperature and blackness should meet the requirements of the furnace, and the flame should not wash the furnace wall, the bottom of the furnace and extend to the convective heating surface.

4. Large adjustment range, can adapt to the need of adjusting boiler load

When the boiler is at the lowest load to the highest load, the burner can work stably without backfire and fireout.

5. Less energy is required for combustion atomization.

6. The resistance of the wind regulating device is small.

7. The ignition, ignition and adjustment operations are convenient, safe and reliable, and the operation noise is small.

8. The flow resistance is small and the amount of pollutants generated is small.
