NO x emissions from different commercial gas burners for metal heat treatment applications were measured for a research project of the Gaswärme‐Institut. The burners, rated at up to 50 kW, were installed for the tests in a laboratory combustion chamber operated at temperatures of up to 1400°C. The air for combustion was preheated to maximum temperature of 600°C. Following the tests, the potentials of different NO x control techniques were investigated. Methods explored included staged combustion air injection, staged fuel injection and fuel gas injection into the flue for NO x reduction. The results showed that it is feasible to reduce the NO x content of flue gases by as much as 90%.
