This is typically where the NOx is formed. These hydrocarbons interact with the already formed NOx. Nevertheless, developmental work continues to enhance the design, and improve the performance of existing burners and engineer and develop new and advanced low NOx burners. Home Low NOx Burners. About Low NOx Burners. The exposure to this gas can result in:. Thus, the emission of this gas has to be reduced under all circumstances.

But where does NOx come from? In general, NOx comes from three primary sources:. As you might have gotten an idea of how much harm the burners can cause to the environment. But to overcome this limitation, scientists have designed special ultra-low NOx burners that can manage and optimize the fuel and air mixing which occurs inside the burners and boilers.

As the process is optimized, a large and much more balanced flame is created which reduces the peak flame temperature and hence a minimal amount of NOx is produced. At the same time, the flame structure also works to reduce the oxygen supply to the hottest part of the flame. This not only improves the efficiency of the burner but also decreases the risk of production of NOx. The process is successfully attained in three different stages:. As you can see, as an industrial burner , almost every move is made to ensure that the amount of NOx produced in the burners and boilers is reduced somehow.
