Introduction to the Precombustion Chamber of Low Nitrogen Burners

The low nitrogen burner precombustion chamber is an efficient and low NOx staged combustion technology developed and researched in China in the past decade.

The precombustion chamber is generally composed of primary air (or secondary air) and fuel injection system.

The fuel and primary air quickly mix, forming a rich fuel mixture in the primary combustion zone of the precombustion chamber. Due to oxygen deficiency, only part of the fuel is burned, and volatile matter is released from the fuel in the primary flame zone with poor oxygen and low flame temperature, Therefore, the generation of NOx is reduced.
