PURPOSE:To improve the stability of auxiliary flame and also the stability of main flame by a method wherein a flt part is arranged at a connection part with a fuel feeding cylinder for a combustion plate inlned toward the direction of flow of combustion gas in the gas burner. CONSTITUTION:Fuel fed from the fuel feeding port 3 in the burner tip 2 at the leading end of a fuel feeding cylinder 1 is injected in parallel with the flat part 16 without having an air feeding port 5 formed between the fuel feeding cylinder 1 of the combustion plate 4 and the inclination part so as to form an auxiliary flame 13. During this formation, the flame 13 is combustioned without being abutted against the combustion plate 4 and also without being affected by the air feeding port 5, a part of the hot generated gas is circulated again and then fed to the auxiliary flame 13. Further, at this time, the auxiliary flame 13 is present at an area where the height of the burner tip 2 is enclosed by the flat part 16, so that the hot combustion gas is not directly flowed into a base part of the auxiliary flame 13, and then the auxiliary flame 13 shows a stable combustion. Therefore, the stability of the main flame 14 may be improved more due to the high stability of auxiliary flame 13. |
