This burner comprises a burner outer cylinder, a cylindrical burner inner cylinder provided inside the burner outer cylinder, a compressed air flow channel demarcated between the burner outer cylinder and the burner inner cylinder, and a plurality of fuel nozzles provided inside the burner inner cylinder, the compressed air flowing through the compressed air flow channel being substantially reversed in flow direction in the end of the burner inner cylinder and led into the plurality of fuel nozzles. The compressed air flow channel is provided with a fuel injection peg comprising an upstream fuel injection peg for injecting up-stream fuel and a downstream fuel injection peg for injecting downstream fuel, and is configured so that upstream fuel concentration fluctuations caused by pressure fluctuations in the burner reduce the peak of downstream fuel concentration fluctuations in the burning initiation position of the burner.
