Abstract

The utility model discloses an overlapped water jacket heating flue, which comprises an internal water jacket, an external water jacket and water through pipe. The utility model is characterized in that the internal water jacket forms a flue by itself; the external water jacket is surrounded the periphery of the internal water jacket; a smoke and fire layer is formed between the internal and the external water jackets; the water through pipe is arranged between the internal and the external water jackets. The overlapped water jacket heating flue is arranged on the upper part of the heating boiler or the outlet of the smoke and fire, the smoke and fire can be discharged after the heat being absorbed by the internal and external water jackets when the smoke and fire passes through the flue, so that the heating area is enlarged, the heat utilization rate is increased, the utility model has the effects of strong energy saving and reduced labor strength.

Description

Overlapping water-jacket typ heating flue

Technical field:

The utility model belongs to heating system, is a kind of overlapping water-jacket typ heating flue.

Background technology:

At present, the caloric receptivity of many warming stoves is less, and heat has all run off from flue mostly, both wastes energy, and labor intensive is very inapplicable again.

Summary of the invention:

The technical problems to be solved in the utility model is to reduce the boiler heat to run off, and increases heating surface area.The heating installation of not only saving coal but also reducing labor intensity.

Solution of the present utility model is that the heating flue is made inside and outside two water jackets, wherein inner water sleeve is formed inner flue voluntarily, in the inner water sleeve periphery around outer water jacket, form smoke layer between inner water sleeve and the outer water jacket, install water service pipe between inner water sleeve and outer water jacket, overlapping water-jacket typ heating flue is installed in the top of heating boiler or pyrotechnics exit, when making pyrotechnics, be divided into inside and outside two-layer heat absorption back and discharge through flue.

The utility model is simple in structure, has increased heating surface area, has improved hot utilization rate, reduces labor intensity thereby can save coal.

Description of drawings:

Accompanying drawing 1 is the utility model cutaway view;

Accompanying drawing 2 is the flue cross section view.

The specific embodiment:

The utility model comprises inner water sleeve 1, and outer water jacket 2 and water service pipe 5 constitute, and inner water sleeve 1 is formed inner flue 3 voluntarily, forms smoke layer 4 between inner water sleeve 1 and the outer water jacket 2,2 installings of inner water sleeve 1 and outer water jacket water service pipe 5.

Claims

1, a kind of overlapping water-jacket typ heating flue, comprise inner water sleeve (1), outer water jacket (2) and water service pipe (5) constitute, it is characterized in that: inner water sleeve (1) is formed inner flue (3) voluntarily, form smoke layer (4) between inner water sleeve (1) and the outer water jacket (2), install water service pipe (5) between inner water sleeve (1) and outer water jacket (2).
