PROBLEM TO BE SOLVED: To provide gas combustion equipment preventing occurrence of a thermal fatigue crack at a gas injection orifice of a burner nozzle. SOLUTION: A gas burner 1 is provided with gas fuel piping 7 supplying gas fuel and an annular gas burner ring, a base of which is connected with the gas fuel piping 7. The gas burner ring 11 is made in a shape of a horseshoe with an opening at its lower part so that drain is not accumulated in the gas burner ring 11. A ring structure of the gas burner ring 11 is changed to the horseshoe shape with its lower side cut off in the vicinity of No.(4) and (5) of a burner element 4 to prevent accumulation of the drain. The thermal fatigue crack at the gas injection orifice of the burner nozzle 5 is prevented by preventing the drain from accumulating in the gas burner ring 11. COPYRIGHT: (C)2004,JPO
