Abstract

The utility model provides a novel secondary heater of a furnace. The lower end of the secondary heater is connected with a flue outlet of the furnace, and the upper end is connected with a chimney. The secondary heater comprises an outer pipe (1), a flue pipe (2) and clapboards (3), wherein the lower part of the outer pipe (1) is provided with a water inlet (4), and the upper part is provided with a water outlet (5). The clapboards (3) are respectively arranged under the water inlet (4) and above the water outlet (5) to form a water chamber (6). The clapboards (3) are closely connected with the outer pipe (1), and the flue pipe (2) is closely connected with the upper and lower clapboards (3) respectively. The waste heat of coal in the furnace after burning passing through the chimney is effectively utilized, so that a heating system is fast heated and has high temperature. After secondary heating, the temperature of the water outlet is increased by 10-30 DEG C, and the maximum temperature can achieve 100 DEG C. 10-20% of coal can be saved annually, and normal boiling water, cooking and the like are not influenced. The waste heat of the furnace after secondary heating reduces temperature, so the dust emissions are reduced, and the purposes of energy saving, emission reduction and high efficiency are achieved.

Description

The after-heater of central heating stove
Technical field
The utility model relates to the after-heater of heat supply furnace, particularly a kind of domestic heating stove.
Background technology
Common family expenses indigenous heating stove has the heat of 30-40% outdoor by the chimney discharge behind coal burning, heat waste in vain, and heating system is also not very awfully hot.Usually stove and accessory manufacturer often pays attention to manufacturing and designing of body of heater internal structure, has ignored the energy through chimney, and the producer that has adds the chuck hydroecium on the body of heater chimney, and it is also undesirable to add thermal effect.
Summary of the invention
In order to overcome present domestic heating stove above shortcomings, the utility model provides a kind of after-heater of novel household furnace, it does not need other energy, the waste heat that only needs the flue gas of stove, not only can improve the boosting power of furnace, make its circulation more unimpeded, and can make full use of waste heat, reduce pollution, energy savings.
The technical scheme that the utility model adopted is: increase an after-heater on the flue outlet of furnace, the last termination chimney of post bake, after-heater comprises outer tube, flue tube and dividing plate, and the outer tube bottom is provided with water inlet, with the delivery port of furnace in succession; Top is provided with delivery port, is connected with the heating system upper hose, below the water inlet and respectively be provided with dividing plate more than the delivery port, constitutes hydroecium, and dividing plate is connected with outer tube enclosure, and flue tube is connected with last lower clapboard is airtight respectively.
Described after-heater is characterized in that flue tube can adopt shell and tube, coil pipe type.
Described after-heater is characterized in that flue tube can adopt the 3-12 root.
The heating system water cycle process is: water enters the after-heater post bake after heating through furnace, passes through heating pipeline again to radiator, by water return pipeline, returns the Natural Circulation process of body of heater.
The furnace after-heater that the utility model provides, effectively utilized in the stove behind the coal burning waste heat through chimney, make heating system heat fast, temperature is high, the delivery port temperature improves the 10-30 degree after the post bake, reach as high as 100 degree, water outlet is condensed into water through independent heat exchanger and enters the heating system filler if the boiling back produces steam is discharged by blast pipe, simultaneously the heating of the water in the heat exchanger can be used for bathing.
Because the key effect of novel indigenous heating stove after-heater, the heating system temperature improves greatly, make heating area increase by 30% than original, year is saved coal 10%--20%, and do not influence normally and heat up water, cook etc., stove waste heat and through lowering the temperature after the post bake has reduced the discharging of dust, played energy-conservation, reduce discharging, purpose efficiently.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a generalized section of the present utility model;
Fig. 3 is an attached view of the present utility model.
Among the figure 1, outer tube, 2, flue tube, 3, dividing plate, 4, water inlet, 5, delivery port, 6, hydroecium.
The specific embodiment
Get Isometrical with chimney, the h=500mm seamless steel pipe is manufactured heater outer tube 1, hydroecium 6 high 480mm, diameter Flue tube 2 selects diameter Four in seamless steel pipe, dividing plate 3 adopts Disk, be connected outer tube 1 inboard, each communicates water inlet 4, delivery port 5 with outer tube 1 with one-inch gas thread silk head, more than all connecting portions be to weld entirely.

Claims (3)

1. the after-heater of a central heating stove, the lower end of after-heater links to each other with the flue outlet of furnace, last termination chimney, it is characterized in that described after-heater comprises outer tube (1), flue tube (2) and dividing plate (3), outer tube (1) bottom is provided with water inlet (4), top is provided with delivery port (5), respectively be provided with dividing plate (3) below the water inlet (4) and more than the delivery port (5), constitute hydroecium (6), dividing plate (3) and airtight connection of outer tube (1), flue tube (2) respectively with airtight connection of last lower clapboard (3).
2. after-heater according to claim 1 is characterized in that flue tube (2) can adopt shell and tube, coil pipe type.
