The specific embodiment
To combine accompanying drawing and specific embodiment that the present invention is done further explain below.
Embodiment one: as shown in Figure 1, a kind of domestic biomass combustion furnace comprises the body of heater 1 with air chamber 2; And flue of settling in the air chamber 2 of body of heater 13 and the bell 4 on the body of heater 1, the loam cake of said flue 3 outstanding bodies of heater 1 suitable for reading also comprises blower fan 5; Said blower fan 5 is air chamber 2 air-supplies of body of heater 1 through the fan wind inleting tube 6 of body of heater 1 bottom, and said flue 3 is arranged in the air chamber 2 of body of heater 1 through support 7, and the bottom surface of flue 3 bottom surfaces and said air chamber 2 does not join; The bottom surface of said flue 3 is provided with the main wind pushing hole 8 that communicates with said air chamber 2, and said support 7 is round table-like network structure, and its bottom surface is conflicted on the bottom surface of said air chamber 2; Its connected mode can be to be tightly connected with screw, also can be that other connects, and said flue 3 is placed in the upper bottom surface of this support 7; Its connected mode can be that screw connects; Also can be that other connects, air chamber 2 bottom surfaces in the present embodiment be rounded, and the bottom surface of above-mentioned support 7 is also rounded; And its radius equates that with air chamber 2 bottom surface radiuses support 7 just can tightly be installed on the bottom surface of air chamber 2 like this.Said body of heater 1 has an air chamber 2; Present embodiment is blown into air through the blower fan 5 of body of heater 1 bottom in air chamber 2; Through the main wind pushing hole 8 of flue 3 bottom surfaces air is sent in the flue 3 again; Can effectively guarantee the amount of oxygen in the flue 3, promote the abundant burning of its fuel, avoid cigarette greatly and the problem of extinguishing easily.
Said flue 3 inside are divided into the fuel region of bottom and the flame zone of top, fuel region; Said flue 3 side wall upper part are provided with the spiral spiral wind of inwall hole 9 and charge wind hole 10; The said wind hole 10 of charging is positioned at the flame zone of flue 3, and said spiral wind hole 9 is positioned at the top in the above-mentioned wind hole 10 of charging.During use, blower fan 5 is blown into air to air chamber 2, and flue 3 fuel constantly burning cause air minimizing in it; Air is except getting into the flue 3 from main wind pushing hole 8, and remaining is then got into spiral wind hole 9 by the wind hole 10 of charging, and consumes a large amount of air because flue 3 fuel are constantly burnt; And main wind pushing hole 8 needs behind the fuel region, just can rise to flame zone; Supply the output of fuel combustion and flame, but it can not satisfy the demand of flame zone to air far away, the air in the air chamber 2 then can get into flame zone by the wind hole 10 of charging fast; The formation shape of charging; Carry air to flame zone apace, it both can provide fuel combustion necessary air to flame zone, can flame upwards be transferred out flue 3 again; Another part air of air chamber 2 then gets into flues 3 by spiral wind hole 9, and because of the inwall in spiral wind hole 9 shape in the shape of a spiral, air can form eddy current after it gets into flue 3; Strengthened flowability,, promoted flowing of flue 3 interior air and flame especially not only for it provides burning required air again; Air and flame in the flue 3 are fully stirred, make air more even with burning, flue 3 fuel combustion get more abundant; And flame is more prosperous, exports higher.
Said bell 4 is tapered; Its top be tubular fire the tube 17; Tube 17 the sidewall that fires is provided with induced draft hole 12, and tube 17 inside that fire are provided with crater 18, when flue 3 fuel during in burning; Air just can reduce gradually in it, bell 4 air outside then since action of negative pressure through above-mentioned induced draft hole 12 get into the tube 17 that fires flame zone.Therefore the internal diameter of crater 18 can form pressure less than the internal diameter of fan wind inleting tube 6 in flue 3, make temperature rising in the flue 3.The present invention is through main wind pushing hole 8, spiral wind hole 9, the repeatedly air distribution such as wind hole 10 and induced draft hole 12 of charging; Impel flue 3 interior temperature risings and fuel combustion to get more abundant with the pressure that can form in 18 pairs of flues of crater 3; Firepower is powerful; Make its fuel produce Pintsch process, fuel is fully burnt, can reach effects such as energy-efficient, smokeless and dust free, low-carbon environment-friendly.And bell 4 is designed to taper, compares with common bell, and its outlet is littler, and the height of flame ejection and the temperature of flame then can be higher, and firepower is more powerful.
In addition, be insulation and the safe effect that strengthens this combustion furnace, on the bottom surface of body of heater 1 inwall and/or flue 3 outer walls and/or air chamber 2, be provided with heat-insulation layer 11.
This combustion furnace burns through prepackage fuel, and less expensive is fit to be widely used.
Embodiment two: as shown in Figure 2; The combustion furnace of present embodiment also comprises the feed mechanism of transfer the fuel in flue 3; Said feed mechanism is made up of loading hopper 13, the conveyance conduit 14 and the propulsive mechanism that communicate with flue 3, and said propulsive mechanism is the spiral propeller 16 that is arranged in the conveyance conduit 14 and is driven by motor 15.All the other structures of present embodiment are identical with embodiment one.
Through feed mechanism flue 3 fuel are sprung up reinforcedly, need not to pre-install fuel at every turn, especially be suitable for the downdraft burning, i.e. burning from top to bottom, and cigarette is few, has increased the adaptation of product, and higher with being worth in fact, use more should be widely promoted.
The above is merely preferred embodiment of the present invention, so can not limit the scope that the present invention implements with this, the equivalence of promptly doing according to claim of the present invention and description changes and modifies, and all should still belong in the scope that patent of the present invention contains.
