A block-like curtain of reticulated ceramic foam is spaced forwardly of the burner nozzle of an industrial burner and, when heated by the flame of the burner, oxidizes unburned CO into CO2 to reduce the emissions of CO. By virtue of the curtain reducing the CO emissions, the burner may operate with a slower, longer and lower temperature flame so as to reduce NOx emissions. The curtain may be adjusted toward and away from the burner nozzle in order to correlate the position of the curtain with the length of the flame.
