Abstract

The utility model relates to a high efficiency energy-saving boiler which comprises the outer shell 7 of the boiler. The lower part of the outer shell 7 of the boiler is provided with a lower combustion chamber 1, a hanging bag 2 is arranged above the lower combustion chamber 1, and a preheating water pipe 3 which is arranged in a horizontal way is arranged above the hanging bag 2. A plurality of rows of water pipes 4 which are arranged in a horizontal way and are vertical to the horizontal direction of the preheating water pipe 3 are arranged above the preheating water pipe 3. A turritus flue 5 is arranged above the water pipes 4, and the top of the flue 5 is provided with a chimney 6. The utility model has the advantage of simple structure. Flame gas rotates and flows many times, and flame gas combusts by secondary air. Therefore, the combustion efficiency is high, the residual heat utilization rate is high, and the utility model has the effect of high efficiency and energy saving.

Description

Energy saving non-pressure boiler

The utility model relates to a kind of combustion apparatus, specifically is meant a kind of energy-efficient pressure-less boiler.

Boiler is widely used combustion apparatus at present, the equipment of pressure-less boiler many especially units supply boiling water and hot water, the greatest drawback of the pressure-less boiler that uses is that its efficiency of combustion is not very high at present, and waste heat does not make full use of, cause the waste of the energy, simultaneously because of very fully not the causing entering in the flue dust of atmosphere and have a lot of pernicious gases of burning, atmosphere pollution influences health.

Goal of the invention of the present utility model is that open kind makes full use of waste heat, reduces the energy-saving efficient boiler of atmosphere pollution.

Provide structure of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the sectional structure chart of facing of a kind of embodiment of the present utility model.

Fig. 2 is a side-looking cross-sectional view embodiment illustrated in fig. 1.

See also Fig. 1～Fig. 2, structure of the present utility model is as follows: bag stove outer covering 7, its underpart is lower combustion chamber (1), lower combustion chamber 1 top is for hanging courage 2, the top of hanging courage 2 is provided with horizontal preheating water pipe 3, hot-water line 3 tops are provided with many rows and the perpendicular horizontal water pipe 4 of hot-water line 3 horizontal directions, and the top of water pipe 4 is a turriform flue 5, and the top of flue 5 is a chimney 6.In the described stove outer covering 7 is inner bag 8, inside and outside courage is welded into integral body by top end socket, lower raft, central dividing plate is divided into warm water chamber and following boiling water chamber with boiler, warm water chamber, hang courage and boiled water tank, hang courage 2 and be connected the back with inner bag 8 it forms four and half garden shape quirks between the two by being connected to form a big linker interior communicating pipe.

During burning, formed flame rises by four and half garden shape quirks in the lower combustion chamber 1, rise to certain position, the secondary air of getting back, and then finish the first step of flue gas flow, the flame flow of Shang Shenging second step of finishing flame flow by horizontal preheating water pipe 3 afterwards, last flame flow continues the 3rd step of rising and finishing flame by horizontal water pipe 4, and the nubbin of flame flow is discharged outside the boilers by flue 5 and chimney 6 then.

The utility model is simple in structure, because of flame gas repeatedly turn round mobile, and secondary air burning, Gu the efficiency of combustion height, utilization rate of waste heat is very high, has energy-efficient effect.

Claims

1, a kind of energy-efficient pressure-less boiler, comprise stove outer covering (7), it is characterized in that stove outer covering (7) bottom is lower combustion chamber (1), lower combustion chamber (1) top is for hanging courage (2), the top of hanging courage (2) is provided with horizontal preheating water pipe (3), hot-water line (3) top is provided with many rows and the perpendicular horizontal water pipe (4) of hot-water line (3) horizontal direction, and the top of water pipe (4) is turriform flue (5), and the top of flue (5) is chimney (6).

2, by the described boiler of claim 1, it is characterized in that being inner bag (8) in the described stove outer covering (7), inside and outside courage is by the top end socket, and lower raft is welded into integral body.
