Abstract
The utility model relate to a vertical boiler, in particular to a sectional high-effective boiler, consists of a boiler body, a combustion chamber and a flue, and is characterized in that the boiler body is incorporated by an upper boiler body and a lower boiler body. The lower boiler body is composed of an annular bearing base and the combustion chamber securely positioned on the annular bearing base. The combustion chamber is a U-shaped water jacket structure in the section. A reverse conic-shape water jacket is securely arranged between a side wall and a bottom of the U-shaped water jacket, and communicated with the water jackets on the side wall and the bottom of the U-shaped water jackets. The side wall and the bottom of the reverse conic-shape is formed into the annular flue. The reserve conic-shape water jacket is provided with 1-4 smoke exhaust hole(s). The upper boiler body is an enclosed container. The inside of the enclosed container is equipped with a secondary heat absorber of the smoke exhaust type. The utility model has the advantages that the smoke is guided into the secondary heat absorber of the smoke exhaust type through the flue, thus enabling a sufficient absorption of the waste heat in the smoke; also, can conveniently provides the hot water or steam through the reasonable connection of the pipelines; and has the advantages of a novel structure, a high utilization rate and a small environmental pollution.
