PURPOSE:To facilitate complete combustion of a preheating combustion flame, by a metod wherein the preheating combustion flame is burnt as it is returned to a gas generating chamber again through a return window from a combustion body. CONSTITUTION:A combustion body 1 and a gas generating chamber 10, which are situated adjacent to each other, are communicated at the interior with each other through a single flow-in window 13, bored in the forward end side of a recess flame wall surface 3, and two return windows 14, 14 which are provided in laterally symmetrical positions on the base end side. A preheating combustion flame, formed in the gas generating chamber 10, freely flows in the combustion body 1 through the flow-in window 13 from the gas generating chamber 10, and a part of the preheating combustion flame, flowing in a gas chamber 2, is returned to the base end side of the gas generating body 10 through the two return windows 14, 14. Free return of the preheating combustion flame to the combustion body 1 and the gas generating body 10 causes an increase in the area of the combustion chamber, resulting in achievement of complete combustion of the preheating combustion flame. |
