PROBLEM TO BE SOLVED: To provide a small heat storage combustion apparatus which is compact with a lower NOx by utilizing jetting energy of a fuel. SOLUTION: A fuel gas is alternately injected from first and second gas nozzles 23a and 23b by alternately opening or closing first and second changeover valves 24a and 24b, passes through first and second current plates 22a and 22b facing each other while the surrounding air for combustion and exhaust gas are sucked and pass through the first and second current plates 22a and 22b. The fuel gas is burnt in a combustion space and the exhaust gas is discharged through the first and second current plates 22a and 22b other than those where a flame is formed. The waste heat of the exhaust gas is recovered by the first and second plates 22a and 22b to preheat the fuel gas and the combustion air in the subsequent changeover combustion. |
