Miniature energy-saving consumption-reducing vertical bearing boiler

Abstract

The invention relates to an improved design of a vertical pressure boiler with small size, energy saving and consumption reduction. The design structure comprises a water tank of the boiler and a combustion chamber on the upper part of the water tank. The key improvements of a flue which is used for communicating the combustion chamber with a chimney port are as follows: first, the water tank is reformed into a vertical pressure vessel; second, the vertical pressure vessel is located on the upper part of the combustion chamber formed by an outer sheath and compound refractory materials, the periphery of the vertical pressure vessel is provided with an insulation casing, a flue gas channel is formed between the insulation casing and the pressure vessel, and a chimney interface is arranged on the lateral side of the upper end of the insulation casing; third, rib shaped tubes are evenly distributed between the upper section and the lower section, and on the periphery of the vertical pressure vessel; fourth, an upper flue gas damping separator and a lower flue gas damping separator are separately arranged between the flue gas channel and the combustion chamber, the flue gas channel and the flue gas vent.

Description

technical field [0001] The invention relates to a small vertical pressure-bearing boiler. technical background [0002] Most of the small vertical boilers currently used are atmospheric water tube boilers. The design is relatively simple, and a sandwich water jacket type water tank is usually used. A combustion chamber is arranged under the water tank, and the flue connecting the combustion chamber and the chimney mouth passes through the water tank. In order to prevent a large amount of heat loss caused by the central flue structure, the existing small vertical boilers are constantly improving the shape and arrangement of the heat exchange mechanism in the water tank and the flue to improve the thermal efficiency of the small vertical boiler . However, the basic structural form of small vertical boilers has not been improved. With the needs of industrial development, small vertical pressure boilers for small and medium-sized industries have formed a market demand. It is n...

However, the basic structural form of small vertical boilers has not been improved. With the needs of industrial development, small vertical pressure boilers for small and medium-sized industries have formed a market demand. It is no longer possible to meet the market demand only by increasing the steel grade and thickness. , especially the substantial price increase of steel and coal at present, making the manufacturing cost and application cost of small vertical pressure boilers remain high
