SHAPED BURNER PIECE WITH INTERNAL FLUE GAS RECIRCULATION

patent

The cylindrical burner fitting consists of an inlet gas-air diffuser and an outlet gas-air flue diffuser at an axial distance in front of it, the diffusers are connected together by four ribs regularly spaced along the inner circumference of the fitting. The gas-air diffuser has a hollow conical constriction terminated by a cylindrical rectifier and the gas-air flue diffuser has a hollow conical constriction terminated by a cylindrical rectifier, the gas-air flue diffuser has a larger diameter at the beginning and end of the constriction than the diameter at the beginning and end of the constriction of the gas-air diffuser and in the interstices between the outer surface of the gas-air diffuser and four evenly spaced flue gas ducts with flue gas inlets are formed on the circumferential shell of the fitting by the inner face of the flue gas diffuserand the inner surface of the constriction, and groove-shaped channels are formed on the outer circumference of the fitting along its entire length, which are embedded in each rib.
