Abstract: A burner nozzle for cutting purposes and provided with channels conducting cutting gas, burner gas and heating gas. The cutting gas channel extends rectilinearly through the entire nozzle. One of the other channels is annularly formed around the cutting gas channel and is connected at the outlet end of the nozzle to an annular chamber. Said chamber is connected with a plurality of narrow channels being inclined or turned relative the axis of the nozzle. Said narrow channels are mainly intended for the burning gas and said annularly formed channel is intended for the heating gas. The burning and heating gases are mixed when the heating gas flows out from said annular chamber in said inclined or turned channels. The gas mixture is arranged to flow annularly out around the jet of cutting gas and form a heating flame.
