PROBLEM TO BE SOLVED: To provide an oxygen enrichment device which can mix added oxygen gas and combustion air homogeneously in a short distance. SOLUTION: A pipe (2) for oxygen get is thrusted, in such condition that it crosses the streamline of combustion air, into a combustion air supply path (1) which supplies a combustion burner with combustion air. A plurality of oxygen nozzles (6) are arranged, along the axis of the pipe (2) for jetting oxygen, at the peripheral face of the pipe (2) for oxygen jet positioned upstream in the streamline of combustion air. The pipe (2) for oxygen jet is connected in communication with an oxygen supply source. |
