The purpose of this utility model provides does not a kind ofly have that heating surface pollutes, the deashing snaking easily and thoroughly, boiling water is fast, simple in structure, the life-span long, it is convenient to repair, and can guarantee the no setting-out membrane structure three backhaul boiler for domestic of long-term energy-efficient operation.
In order to achieve the above object, the utility model has been cancelled the water pipe heating surface and has been adopted full moisture film structure.And utilize
The shape moisture film is divided into two the flue of routine, just is provided with one in flue
Leave certain distance between the shape moisture film, it and flue top to constitute two parts connected entrance before and after the flue, be provided with the fin-shaped moisture film to constitute the heat convection space at boiler tail.
Shape moisture film vertical section preferably places on the vertical bisector plane of flue,
Shape water mould top heating surface has the above inclination of 10 degree, and the stagnant phenomenon of vapour appears in the top in the moisture film to avoid.Fin-shaped moisture film upper and lower side also has the above inclination of 10 degree, to avoid the stagnate deposition of temporary hardness of phenomenon and water of vapour.
In the flue
The shape moisture film is divided into two flue, red-hot flame and high-temperature flue gas are upwards flowed from flue first half space, flow downward in the latter half of space of flue again from flue top folding turnback then, level is left flue when arriving foot, and along upwards flowing with the fin-shaped moisture film heat convection space of boiler jacket wall formation, leave stove and enter atmosphere from this top, space outlet at last, thereby formed the heat exchange of three backhauls.
The ∽ shape that the shape moisture film has been controlled flame and flue gas closely flows to, and has prolonged flue gas flow, has improved the boiler output and the thermal efficiency greatly.Flue dust is because the most of bottom that is deposited on outlet of flue high-temperature flue gas and afterbody heat convection space of concentrating of inertia, can remove easily totally by little shoot door, not only reduced environmental pollution by self dedusting, and the cleannes of heating surface have been kept for a long time, thereby improved heat-transfer effect, guarantee long-term energy-efficient operation, thermal efficiency energy all-the-time stable is more than 75%.Afterbody fin-shaped moisture film has replaced conventional vertical water pipe,
The shape moisture film has replaced many horizontal water tubes, has also removed a large amount of hand hole devices from simultaneously, utilizes top to go into aperture apparatus, can easily clear up up hill and dale
Incrustation scale in shape moisture film and the afterbody fin-shaped moisture film.Such boiler structure is simple, and the life-span is long.
