Description

The energy-conservation stove of S flue

Technical field:

The utility model relates to the energy-saving civil stove, especially the energy-conservation stove of S flue.

Background technology:

At present, Civil energy-saving cooking stove in the farming and pastoral area and combination area of city and country area use wider, because the simple general combustion rate of furnace binding is all lower, in the prior art, the flue of burner hearth junction is generally shorter, and hot flue gas and water jacket heat exchange contact area deficiency objectively cause outside exhausting phenomenon, cause the insufficient discharge flue dust that causes of burning to exceed standard seriously, easily environment is polluted.

Summary of the invention:

The purpose of this utility model provides a kind of heat exchange structure that increases in burner hearth, prolong the higher atmospheric energy-saving water heater of the thermal efficiency of flue effective length, i.e. the energy-conservation stove of S flue.

Realize that the measure of the present utility model purpose comprises: body of heater internal fixation burner hearth, outside the burner hearth and between furnace body outer wall water jacket is set, body of heater rear portion upper fixed outlet flue, water box before the burner hearth back upper place is fixing, the bottom is communicated with water jacket in the preceding water box, fixing back, water box rear water box before in the body of heater, back water box internal upper part is communicated with water jacket, the burner hearth rear portion upwards through preceding water box with after water box gap downwards then upward commentaries on classics be connected outlet flue lower end formation S shape flue.

Advantage of the present utility model is: S shape flue has increased heat exchange area, has improved the thermal efficiency, and it is energy-conservation, efficient to work, sufficient combustion, and heat waste is little, fuel savings, environmental protection and energy saving.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment 1

Reference numeral comprises: outlet flue 1, and body of heater 2, kitchen range mouth 3, back water box 4, the heat exchanging water pipe 5, fire door 6, burner hearth 7, air door 8, fire grate 9, water return outlet 10, delivery port 11, water jacket 12, flue 13, preceding water box 14, ash bin 15, ash hole 16.

The specific embodiment:

Embodiment 1: body of heater 2 internal fixation burner hearths 7, outside the burner hearth 7 and between body of heater 2 outer walls water jacket 12 is set, body of heater 2 rear portion upper fixed outlet flues 1, water box 14 before burner hearth 7 back upper places are fixing, bottoms are communicated with water jacket 12 in the preceding water box 14, fixing back, water box 14 rears water box 4 before in the body of heater 2, back water box 4 internal upper parts are communicated with water jacket 12, burner hearth 7 rear portions upwards through preceding water box 14 with after water box 4 gaps downwards then upward commentaries on classics be connected outlet flue 1 lower end formation S shape flue 13.Open kitchen range mouth 3 on the body of heater 2 of burner hearth 7 tops.

Fixing water return outlet 10 and the delivery port 11 that is communicated with water jacket 12 of body of heater 2 outer walls.Body of heater 2 internal furnaces 7 lower horizontal fixed grates 9, burner hearth 7 external furnace bodies 2 outer wall blow-on doors 6.Fuel adds on the fire grate 9 through fire door 6.Fire grate is provided with ash bin 15 9 times in the body of heater 2, on ash bin 15 external furnace bodies 2 walls ashpit 16 is set.The heat exchanging water pipe 5 who is communicated with water jacket 12 along horizontal fixed in the burner hearth 7.The heat exchanging water pipe 5 that horizontal fixed is communicated with water jacket 12 in the flue 13.

Fuel combustion after heat flue gas rises along burner hearth 7 on the fire grate 9, earlier heat exchanging water pipe 5 and preceding water box 14 downside water in the thorax pipe 7 are heated, after when further water box 14 and water box 4 gaps, back are downward before S shape flue 13 is crossed to preceding water box 14 upsides and back water box 4 downside water, and heat exchanging water pipe 5 heats in preceding water box 14 and water box 4 gaps, back, upwards effluxes through outlet flue 1 along changeing heating heat exchanging water pipe 5 backs on the S shape flue 13 with the after heat flue gas.S shape flue 13 has effectively prolonged heat exchange contact area and space, improves the thermal efficiency, and fully flue gas cool-down is obvious after the heat exchange, the abundant sedimentation of flue dust, and the discharged gas fume clean level obviously improves.

S shape flue 13 has increased heat exchange area among the utility model embodiment, has improved the thermal efficiency, and it is energy-conservation, efficient to work, sufficient combustion, and heat waste is little, fuel savings, environmental protection and energy saving.
