PURPOSE:To improve the radiating efficiency, and prevent the titled device from producing of carbon monoxide and odor by a method wherein a red-hot cylinder is provided at the upper part of a inner flame cylinder, and a movable damper which controls the amount of the air flow passing through a upper opening part of said red-hot cylinder is also provided. CONSTITUTION:A first red-hot cylinder 4 connected with the upper part of a outer flame cylinder 3, a light permeable outer cyliner 5 composed of a heat resistant and light permeable material such as a glass and the like, and metallic outer cylinder 6 etc. supporting said outer cylinder 5 are prepared. Then, a inner flame cylinder 2, said outer flame cylinder 3 and said metallic outer cylinder 6 are arranged in almost concentric manner, in order from inside to outside, by the appropriate means. Further, a interstructure plate 7 connected with said inner flame cylinder 2, a second red-hot cylinder 8, an upper cover 9 supporting said the second red-hot cylinder 8, and an air opening 11 are arranged. An air inlet 10 is provided between said inner flame cylinder 2 and the second red-hot cylinder 8. A movable damper 12 is connected with a outside burning adjusting mechanism by a connecting rod 13, accordingly, moved up and down. |
