A low oxygen vortex burner is provided. With the use of exhaust gas discharged from a combined boiler internal combustion engine as a supply source of air for re-combustion, it is possible to have the exhaust gas discharged in a state of complete combustion and to suppress the pollution of the natural environment due to the exhaust gas. The low oxygen vortex burner includes: a frame 100 including a barrier plate 130 for segmenting an inlet space 110 and a combustion chamber 120; an outer casing 220 having a plurality of vortex pipes 400 arranged thereon with the same intervals in a tangential direction of the outer casing so as to cause a vortex of the exhaust gas introduced from said inlet space 110 of the frame 100; a nozzle 500 installed along an axial direction of said outer casing 200 and injecting fuel for combustion; an orifice 800 formed at a location corresponding to an end of said nozzle 500 and passing the exhaust gas in the outer casing 200 and the fuel with a higher speed for accelerating the combustion; a choke 700 formed at the opposite side of said orifice 800 located at a side of said combustion chamber 120 so as to re-circulate a flame within the combustion chamber 120; and fire-resistive materials 600 surrounding the combustion chamber 120 except for said choke 700 and said orifice 800.
