Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of air jet pipe among Fig. 1;

Fig. 3 is the structural representation of movable sheet 9 among Fig. 1.

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model is by body of heater, and catalysis aerogenesis apparatus and loose-leaf three parts are formed.

As shown in Figure 1, the body of heater profile is all similar with normal domestic use three joint honeycomb briquette stoves with structure: in furnace shell 3, be provided with heat-insulation layer 2 and flue 1 successively.In the outside of furnace shell 3, the storage box 17 and the switch valve 15 of a storage catalytic liquid is housed, both are communicated with sebific duct or rubber tube 16.

The catalysis aerogenesis apparatus is positioned at furnace shell 3, and by gasification courage 4, air supply pipe 5 and air jet pipe are formed, and the three is arranged above and below and is communicated with successively.Being enclosed within the gasification courage 4 on the flue 1, is to be welded with 2 block plates, and formed interlayer inner chamber can hold catalytic liquid or by the formed fuel gas in catalytic liquid heat absorption back.One side of gasification courage 4 is provided with a weldering pipeline even with it, and the other end of pipeline (being the import termination) is threaded with the switch valve 15 that passes furnace shell 3 sides, is fixed on the furnace shell 3; Opposite side then welds with air supply pipe 5.

As shown in Figure 2, air jet pipe by one be responsible for 8 and with it the arm 10 of weldering company form.The quantity of arm 10 generally is 4, and middle 2 are long slightly, and 4 nozzle bores 18 are respectively arranged, and two is short slightly, and 2 nozzle holes 18 are respectively arranged.Being responsible for 8 is straight tubes, connects with fire grate 6 welderings.Arm 10 is arranged in the fire grate mouth, and its effect one is jet to flue 1, and the 2nd, can support coal cinder; Being responsible for 8 also can be winding form, becomes " L " shape (see figure 1), and arm 10 is welded in that level folding pipe is gone up and it is between fire grate 6 and furnace bottom.An end of the person in charge 8 (upper end, folding part) links to each other with air supply pipe 5 screw threads and is fixed on the fire grate 6 with nut 7, and the other end is equipped with blowdown nut 12.Back out nut 12, promptly available pin or thin wire are disclosed out the pipeline that is stopped up by dirt.

Loose-leaf comprises that partly movable sheet 9 and the handle 12(that is attached thereto see Fig. 1), movable sheet 9 usefulness bolts, nut 11 activities are contained in the furnace bottom below.As shown in Figure 3, on the movable sheet 9, have with the identical shape of the slag-drip opening of furnace bottom, equirotal 2 slag-drip openings 19, its effect one is a deslagging, the 2nd, play the fire door effect, the air mass flow that control enters flue.0-4 scale arranged on the furnace shell 3, and numeral is big more, and it is big more to represent that the movable sheet 9 and the slag-drip opening of furnace bottom overlap degree, and for example scale 4, and the expression full weight is closed (being equivalent to the fire door standard-sized sheet).And for example handle 13 is when scale zero, and both slag-drip openings are completely wrong to be opened (be fire door close bank up a fire).Sequence number 20 is apertures, passes for bolt 11.

Sequence number 14 is stove pin.Each stove pin becomes del to arrange with 3 screws, makes stove pin upper end fixing with furnace shell 3, and wherein Shang Fang two screws are longer, so that after passing furnace shell 3, can support fire grate 6.

Need heat up water when cooking, can stir handle 13 by 0 to 1 grade of scale or other scale position as required, so air flows in the flue, coal cinder takes fire.Wait a moment, opening switch valve 15(this measure is in order to save catalytic liquid, if body of heater has temperature or not fire extinguishing always, can be not limited), like this, catalytic liquid in the fluid storage tank 17 under the pressure of self in sebific duct 16, switch valve 15 constantly flow into courage 4 chambeies of gasifying, be gasificated into combustible gas after being heated immediately.Hot gas flows in the air jet pipe through air supply pipe 5, is sprayed to burner hearth by nozzle hole 18, burns with red carbon, and very fast raising furnace temperature makes the thorough conflagration of coal.This is because behind the red carbon of gasification liquid one contact, just meet thermal decomposition and go out oxygen element, most of result with the direct and red carbon reaction of atomic state.

If when not needing big fire or in time not replenishing catalytic liquid, the utility model also can resemble common coal stove and use.Because the former fire door goes to the lower end of furnace bottom, improved the effect of ventilating, so make its combustion efficiency improve 1-3 doubly than the latter approximately.
