Condition "NOx” stands for nitrogen oxides, a group of dangerous greenhouse gases. When fuel is burned at a high temperature, such as in an engine or a home gas stove, these gases are emitted. Low NOx and Ultra-Low NOx are terms used to describe product emission limits, which are set by regional EPA guidelines and differ for different types of heating equipment.

Low NOx emissions indicate that cold, premixed combustion played a significant role. In order to take into account the reduced NOx emissions, a conceptual modeling is proposed that explains the mixing process inside the combustion chamber.
