PURPOSE: To make an apparatus light and the assembling work easy by forming opening parts in a side wall for making a gas transversely flow in a combustion cup in a housing, producing a chamber from the side wall, an end part wall, and a cover, and forming opening parts in a side wall for making a gas transversely flow in a diffuser cup. CONSTITUTION: A housing 40 is constituted of a diffuser cup 42, a combustion cup 44, and a combustion chamber cover 46 and the side wall 50 of the diffuser cup 42 is formed between an upper part circular end plate 54 and a lower part circular flange 56. Gas outlet opening parts 58 are formed in the upper part of the side wall 50 in a circular arrangement and the combustion cup 44 is installed in the inside of the diffuser cup 42 and a side wall 60 is formed between a flat and non-porous front part end wall 64 and the lower part circular flange 56. Gas outlet opening parts 68 are formed in the lower part of the side wall 60 in a circular arrangement. The upper part end wall 64 of the combustion cup 44 is welded to the upper part end wall 54 of the diffuser cup 42 and a combustion cup flange 66 is welded to the diffuser cup flange 56. |
