An oxygen burner is provided which flame is digested with the emitted fuel even if the flame of the high temperature is required and the fuel of the large amount is emitted in the oxygen burner through vent is provided. An oxygen burner comprises a burner body consisting of an oxygen inlet(11) and an oxygen nozzle part(10) discharging oxygen through the oxygen inlet; a fuel nozzle part(20) in which the fuel inlet(21) which supplies the fuel is equipped while being inserted through in the burner body. An oxygen outlet(12) of the oxygen nozzle part and fuel outlet of the fuel nozzle part have the step height(T1) in order to increase the mixing efficiency of the fuel and the ejected oxygen. An auxiliary air nozzle part(30) for improving the directivity of the flame due to the firing of the fuel and oxygen is equipped on the fuel nozzle portion. The air outlet of the auxiliary air nozzle part has the step height(T2) about the fuel outlet of the fuel nozzle portion. The oxygen outlet of the oxygen nozzle part is formed with the radial structure.
