Abstract

The utility model relates to an energy-saving boiler, which comprises a boiler body and a flame tube. The boiler body is of a sandwich-header structure, the lower portion of the boiler body is a hearth, the boiler body is communicated with the flame tube which is further provided with conducting strips outside, and the cavity between the inner surface of the boiler body and the flame tube is a flue. The flame tube of the energy-saving boiler is externally provided with the conducting strips, which extends the heat-absorbing area. The conducting strips prevent the rising of the flue gas, which makes that the heat of the flue gas can be used thoroughly, thereby increasing heat conversion efficiency and saving fuel. Moreover, the rising speed of the flue gas slows down, thus the discharge amount of smoke is reduced and pollution is mild.

Description

A kind of power economized boiler

One, technical field:

The utility model relates to boiler, what be specifically related to is a kind of power economized boiler with flue.

Two, background technology:

The boiler structure of people's use at present is different, wherein there is a kind of boiler to constitute by body of heater, flue, the body of heater of this boiler is the intermediate water cell structure, and flue is a tubulose, and flue communicates with body of heater, the bottom of body of heater is a burner hearth, the heat that produces by fuel combustions such as coals heats up to the water in body of heater and the flue, hot water is circulated, but there is the low problem of heat exchange efficiency in this boiler, energy consumption is big, and pollutes big.

Three, summary of the invention:

The purpose of this utility model provides a kind of power economized boiler, and this boiler is used to solve the low problem of original boiler heat exchange efficiency, and is energy-saving and cost-reducing.

The technical scheme that its technical problem that solves the utility model adopts is: this power economized boiler comprises body of heater, flue, body of heater is the intermediate water cell structure, and the bottom of body of heater is a burner hearth, and flue communicates with body of heater, flue has conducting strip outward, and the inner surface of body of heater and the cavity between the flue are flue.

Beneficial effect:

Flue of the present utility model has conducting strip outward, the heat that fuel combustion produces not only absorbs by flue and inboard wall of furnace body, the conducting strip that flue has outward also can absorb heat, this has enlarged the absorption area of heat, conducting strip hinders the rising of flue gas simultaneously, the heat of flue gas is fully utilized, improves heat exchange efficiency, fuel saving; In addition, because the rate of climb of flue gas reduces, the discharge capacity of flue dust reduces, and pollutes little.

1 body of heater, 2 flues, 3 conducting strips, 4 fire doors, 5 shoot doors, 6 peep holes, 7 water inlets, 8 delivery ports, 9 burner hearths, 10 flues

Five, the specific embodiment:

Fig. 1 provides front view of the present utility model, Fig. 2 provides profile of the present utility model, in conjunction with Fig. 1, shown in Figure 2, this power economized boiler comprises body of heater 1, flue 2, and body of heater 1 is the intermediate water cell structure, water inlet 7, delivery port 8 are arranged, the bottom of body of heater 1 is a burner hearth 9, and burner hearth 9 has fire door 4 and shoot door 5, is used to add fuel and cleaning ashes, peep hole 6 is arranged at the top of body of heater 1, is used to observe the combustion case in the stove; Flue 2 communicates with body of heater 1, is arranged in the body of heater 1, and water circulates in body of heater 1, flue 2, has conducting strip 3 outside the flue 2, and the cavity between the inner surface of body of heater 1 and the flue 2 is a flue 10, and conducting strip 3 can be iron plate or copper sheet or aluminium flake.Owing to have conducting strip 3 outside the flue 2, enlarged the absorption area of heat, conducting strip 3 hinders the rising of flue gases simultaneously, and the heat of flue gas is fully utilized, and improves heat exchange efficiency, fuel saving; In addition, because the rate of climb of flue gas reduces, the discharge capacity of flue dust reduces, and pollutes little.

Fig. 3 be A-A among Fig. 2 to profile, provided the distribution situation of same horizontal plane upper furnace among the figure; Fig. 4 is the side view of flue in the utility model.In conjunction with Fig. 3, shown in Figure 4, flue 2 is a tubulose, and its two ends communicate with body of heater 1, and the outside has circular conducting strip 3, and the cavity between the inner surface of body of heater 1 and the flue 2 is flue 10.

Fig. 5 is the structural representation of the another kind of embodiment of the utility model, and in this embodiment, the flue 2 outer conducting strips that have 3 are wrapped in outside the flue 2 for spiral helicine.Remaining structure is all identical with first kind of embodiment.

The outer conducting strips 3 of flue 2 can also be designed to squarely, oval-shaped in the utility model, and certainly, the shape of conducting strip 3 is unrestricted, have conducting strip 3 as long as flue 2 is outer, just in protection domain of the present utility model.In order to observe conveniently body of heater 1 outer thermometer, the Pressure gauge also installed of the present utility model.
