4 split flame burner
The principle is to divide a flame into several small flames. Due to the large heat dissipation area and low flame temperature, the "thermal reaction NO" decreases. In addition, the flame shortens the residence time of oxygen and nitrogen in the flame, and obviously inhibits the "thermal reaction NO" and "fuel NO".
5 mixed promotion burner
The retention time of flue gas in the high temperature zone is one of the main factors that affect the production of NOx. Improving the mixing of combustion and air can reduce the thickness of the flame surface. In the case of constant combustion load, the retention time of the flue gas in the flame surface is shortened, thus the generation of NOx is reduced. The mixing and boosting burner is designed according to this principle.
6 low NOx pre combustor burner
The pre combustion chamber is a high efficiency and low NOx grade combustion technology developed and studied in China in the past 10 years. The pre combustion chamber is usually composed of primary air (or two air) and fuel injection system. Fuel and primary air are mixed rapidly. A fuel mixture is formed in a combustion zone in the pre combustion chamber. Due to oxygen, only some fuel is burned. The volatilization of fuel in the primary flame area with low oxygen and low flame temperature reduced the formation of NOx.
