Most of the combustion systems currently available in the market attempt to achieve their low NOx emissions combined with low CO emissions and stable combustion by employing relatively long flames, staged combustion air/fuel and with mechanical provisions near the flame to create swirl. The EUROPEM Ultra-low NOx burners use a different philosophy to achieve complete and stable combustion along with ultra-low NOx emissions: The use of thin and short flame profiles: Empirical evidence shows that narrow and short flame profiles achieve the lowest NOx emission values. Controlled flame temperatures: The flame temperature is controlled at a temperature high enough to ensure that no CO is formed whilst the temperature is low enough to avoid any NOx formation. Oxygen concentration near the flame is controlled such that the faster hydrocarbon reaction depletes all the oxygen before NOx can be formed by the slower N2 to NOx reaction. Internal flue gas recirculation: The high velocities at the burner mouth create an internal venture effect which in turn results in internal flue gas recirculation around the flame. A stable and uniform temperature profile without hot spots created in the flame will further minimize NOx formation. EUROPEM Ultra-low NOx burners are equipped with a windbox giving tangential entry of the combustion air to create a natural swirl around the flame. This principle is also employed for the waste gases entering the burner so that additional swirl is created by one or more waste gas streams. Support fuel and rich waste gas are injected through a shell type disc to obtain a narrow and short flame profile. A “tulip flame profile” or “balloon flame profile” are selected, depending on the fuel characteristics.
