Claims (8)

Nozzle tip for burner of fine fuel combustor, in which the fine fuel and conveying air are defined between the flow passage from the burner into the furnace, and the inner and inner ends of the open end having the inlet and outlet ends are separated and First and second flows extending from the inlet end of the inner to the outlet end of the inner in such a way that air diverges from the burner to the space formed between the open end and the flow restricting passage, defined between the annular flow passages leading into the furnace. Nozzle tip and vortex preventing plate of the fine fuel burner, characterized in that it comprises a plate means disposed in the interior for branching the flow passage leading to the passage. 2. The plate means according to claim 1, wherein the plate means comprises first and second vortex breakers disposed within the inner rim, wherein the first and second vortex breakers each have an induction end disposed across the inner flow passage at the inlet end. It has an orbital end extending from the outlet end across the inner flow passage, extending along the line at the inlet of the inner end and branching out toward the outlet end of the inner side, coupled by the first swirl preventing plate and the inner side. And a nozzle tip of the fine fuel burner characterized in that it is isolated from the space area as a means for branching the flow passage flowing through the inner passage into the second flow passage coupled by the first flow passage and the second vortex preventing plate and the inner shell. Vortex Vane. 2. The nozzle tip and vortex breaker of claim 1, wherein the first and second vortex breakers branch at an angle of about 20 degrees. 3. The nozzle tip and vortex breaker of claim 1, wherein each track end of the first and second vortex breakers is scalloped. 5. The plurality of track end portions of the first and second vortex breakers of claim 4, wherein the track ends of the first and second vortex breakers extend outwardly from each guide end of the first and second vortex breakers in parallel across the inner flow passage. And a first portion of the orbital end strips being alternately disposed between the second portions of the orbital end strips and bent radially away from each guide end of the first and second vortex breakers. The nozzle tip and the vortex prevention plate of the fine fuel burner, characterized in that the scalloped raceway ends of the first and second vortex prevention plate are formed respectively. 6. The method of claim 5, wherein the second portion of the raceway end strips comprises a first and a first portion in a direction opposite to the direction in which the first portion of the raceway strip is radially bent away from each guide end of the first and second vortex breakers. 2 Nozzle tip and vortex preventing plate of the fine fuel burner, characterized in that the radially bent away from each induction end of the vortex blocking plate. 7. The method of claim 6, further comprising a plurality of spacing plates disposed transversely between adjacent first and second portions of the raceway strip along the common area such that the fuel and conveying air are branched adjacent to the raceway strip. And a nozzle tip and a vortex preventing plate of the fine fuel burner, characterized in that they do not flow across the shared area formed between the second portions. 8. The nozzle tip and vortex breaker of claim 7, wherein the guide ends of the first and second vortex breakers branch at an angle of about 20 degrees. ※ Note: The disclosure is based on the initial application.
