FIELD: power industry.SUBSTANCE: burner nozzle contains nozzle casing. Fuel pipe and pipe for gas sustaining combustion are provided in the nozzle casing. The pipe for gas sustaining combustion is located around the external part of the fuel pipe. The output end of the pipe for gas sustaining combustion goes further then output end of the fuel pipe. The pipe for the gas sustaining combustion is provided with separating pipe that separates the pipe for gas sustaining combustion as first pipe for gas sustaining combustion, and second border pipe for gas. The second border pipe is located around the external part of the first pipe for gas sustaining combustion. The output end of the fuel pipe goes further then end of the separating pipe.EFFECT: pipe end wear prevention of pipe for gas sustaining combustion.7 cl, 3 dwg |
