The effect of the central wind

The central wind plays a crucial role in the burner, and although its proportion is small, its effect is significant. Here are the main functions of the central wind:

Forming a cold air flow zone: the central wind can form a small range of cold air flow zone in front of the coal nozzle to prevent the high temperature flue gas from backflow from burning the nozzle.

Increase the area of the recirculation zone and the central flow rate: The central wind can significantly increase the area of the recirculation zone and the central flow rate, promoting pulverized coal combustion and stable combustion flame, so it is also called "flame stabilizer".

The significance of the central wind

The significance of the central wind is that it has an important impact on the stability and efficiency of the entire combustion process:

Protection equipment: By forming a cold air flow area, the central wind can effectively protect the coal nozzle from high temperature flue gas damage and prolong the service life of the equipment.

Promote complete combustion: central wind helps to increase the area of the recirculation zone and the central flow rate, so as to promote the combustion of pulverized coal, ensure the complete combustion of fuel, and improve the combustion efficiency.

Stable flame: The central wind is essential for a stable combustion flame. It helps maintain the shape and strength of the flame, avoiding problems such as unstable flame or excessive scouring of the kiln skin.

To sum up, the role of central wind in burner is mainly reflected in protecting equipment, promoting complete combustion and stabilizing flame, which is of great significance for ensuring the efficient operation of combustion system and extending the service life of equipment.
