ABSTRACT:
Large numbers of vent holes are respectively formed in inner and outer flame cylinders defining an annular combustion chamber to supply air thereto. A total opening area of the vent holes formed in the outer flame cylinder is greater than that of the vent holes formed in the inner flame cylinder. As a result, the heat capacity of the outer flame cylinder is smaller than that of the inner flame cylinder. During combustion, the outer flame cylinder is heated to red-hot. A plurality of projections are formed on the outer wall surface of the inner flame cylinder to allow complete combustion of a fuel vapor.
