Combustion

Abstract

Abstract PURPOSE:To reduce the concentration of NOx generated from a burner by a method wherein an electrical field is imparted between a fuel nozzle and an electrode arranged at the outlet portion of the fuel nozzle. CONSTITUTION:An annular electrode 2 having larger bore diameter than the outer diameter of the fuel nozzle 1 is connected with a high voltage generator through a high voltage cable 4. The high voltage generated by the high voltage generator 3 is imparted to provide the fuel nozzle 1 side with positive polarity and the electrode 2 side with negative polarity or reverse polarities between the fuel nozzle 1 and the electrode 2 through the high voltage cable 4. According to this method, the concentration of NOx generated from the burner may be reduced remarkably compared with conventional method.
