Zusammenfassung:PROBLEM TO BE SOLVED: To prevent the generation of vibration and noises as caused by combustion while achieving a lowering of NOx in a combustion apparatus of a gas fired boiler. SOLUTION: In this gas fired combustion apparatus in which a secondary burner 2 is arranged surrounding a primary burner 1 and a tertiary burner 3 is provided on the outside or the like of the secondary burner 2. One step part is provided on an internal cylinder wall 4 of a burner tile part provided at the tip of the secondary burner 2 at a position equivalent to 1.5-3 times the inner diameter of the outlet of the secondary burner 2 while the height of the step part is made 0.08-0.5 times the inner diameter of the secondary burner 2. This can prevent the generation of vibration and noises during the combustion and also achieves a lowering of NOx.
