[0002] A low-nitrogen water-cooled burner is a combustion device that produces low nitrogen oxide emissions during the combustion process. It is mainly used to reduce nitrogen oxide emissions during the combustion process, because nitrogen oxides are the main driving force behind the production of acid rain, photochemical smog and ozone destruction, and are also an important culprit for the production of atmospheric ultrafine particulate matter PM2.5. The low-nitrogen water-cooled burner nozzle is a key component of this burner. It is an important component for achieving fuel and air mixing during the burner combustion process. By controlling the flow, direction and speed of the nozzle, the combustion process can be optimized and the combustion efficiency can be improved.

[0003] With people's increasing concern about environmental issues, reducing nitrogen oxide emissions has become an important task facing various companies. During the combustion process, the amount of nitrogen oxides generated is affected by factors such as combustion temperature, oxygen concentration, combustion space and residence time. The traditional burner nozzle structure often makes it difficult to achieve effective control of nitrogen oxides. For this reason, we propose a low-nitrogen water-cooled burner nozzle structure to solve the above problems. Utility Model Content
