3. Defining features of the ultra low NOx burner

1) Ingeniously disperse the fuel across space to supply, significantly reducing the central flame temperature for optimal performance.
2) Experience a stable flame, expertly intertwined with secondary gas to facilitate further combustion, ensuring complete combustion for maximum efficiency.
3) Engage in a sophisticated heat exchange process where flue gas transfers heat to both gas and combustion air-boosting combustion with elevated inlet temperatures.
4) Observe how the design of the brazier brick affects fluid dynamics, strategically influencing the shape and spread of the flame for enhanced control.
5) Achieve a swirling flame by methodically switching the fuel supply on the ring as per specific guidelines, effectively preventing furnace flame erosion.
