MILD oxy-fuel combustion significantly improves furnace temperature uniformity and reduces NOx emissions.
At O2% = 31%, temperature uniformity and emissions reduction are at their peak with MILD combustion.
Higher oxygen concentrations enhance thermal efficiency, yet improvement decreases beyond O2% 51.
MILD combustion is recommended for natural gas or mixed gas use between O2% 51–71; coke oven gas is less effective.
