Abstract： |
The present invention relates to an industrial furnace with high-temp. low-oxygen air burner, which is characterized by that the two ends of furnace cavity are respectively equipped with a high-temp. low-oxygen air burner. Said burner is formed from combustion chamber, combustion chamber end cover which is set at end hole of combustion chamber, possesses a circular through hole in its centre and is formed into a ring channel at end portion of the combustion chamber and cover plate positioned on the end cover of combustion chamber. Said burner can make oxygen being in high-temp. air obtain dilution by means of returned fume and convert it into low-oxygen air, and make the fuel combust under the condition of low-oxygen air, and its oxygen concentration is less than 15%. It not only effectively reduce NOx discharge, but also its discharge temp. only is 150-200 deg.C. so as to attain the goal of saving energy and protecting environment. |
