PROBLEM TO BE SOLVED: To provide a combustion cylinder for an oil combustion appliance capable of preventing deterioration of exhaust gas while enhancing heating capacity.SOLUTION: An upper distributing plate 37 on which a hole part 38 is formed at an inner upper part of an inner cylinder 10 is provided, and also a middle distributing plate 35 on which a hole part 36 is formed at an inner substantially central part of the inner cylinder 10 is provided. Thereby, air flowed into the inner cylinder 10 from a through-hole 5 on an upper surface of a core guide inner cylinder 3 is decelerated by the middle distributing plate 35, one part of the air is blown out into a primary combustion chamber 17 from a small hole 23 of the inner cylinder 10 below the middle distributing plate 35, and also, the air passing through the middle distributing plate 35 is decelerated by the upper distributing plate 37, and one part of th air is blown out into the primary combustion chamber 17 and a secondary combustion chamber 31 from the small hole 23 of the inner cylinder 10 near a front side on the boundary between the primary combustion chamber 17 and the secondary combustion chamber 31. Thus, by accelerating combustion, a value of CO/CO2 of the exhaust gas can be improved. |
