Radiant Wall Burners of high quality and low nitrogen oxides emission, method of operation of the Burner and burner set.

摘要

Set for a Radiant Burner Burner which comprises a Burner in the form of a tubular duct Burner elongated with entry and exit ends Spaced.The Shaft is adapted and arranged to drive a poor fuel gas mixture, which contains a part of the total Fluid to burn Fuel and Oxygen from the inlet end to the Outlet End.The Set also includes, in the output end of the main pipe, a Nozzle Burner has a Central Axis, a wall that extends around a centrally located in the Chamber and an outlet end of the Outlet end of The Conduit spacing.The main Nozzle Burner is prepared and adapted to receive the fuel air mixture in the fuel from the poor and to ReOrient the duct through a Plurality of openings in the wall into a combustion Zone in the direction transverse to the axis and a Speed Th e greater than the flame speed of the gaseous mixture.The Openings are distributed circumferentially around the wall so that the mixture is directed through these openings, without substantial Recirculation with minimal Pressure drop, into the combustion Zone disposed in a pattern Round plane that separates the boqu IllaThe surrounding Wall and extends Outward through the radiating surface of a Ceramic Burner. The Fuel Burner also comprises An elongated Tube extends in a direction substantially parallel to the Axis of the nozzle and the fuel Pipe has one end portion of output.There is a secondary Fuel Nozzle includes a hole for secondary fuel in the portion of output end of the fuel Pipe.The opening of Secondary Fuel is located and arranged to supply fuel to a secondary position on the opposite side to the pattern of fuel on the radiating Surface, and far enough from the combustion Zone to Perm Transmit the same mixing with combustion gas before entering the area.
