Principle of the present invention is described as follows:

1, upper whirlwind is led fiery device 26 and lower whirlwind is led fiery device 27:

Referring to figure 1 – Fig. 5, lead on the inwall of fiery wall 23, being provided with whirlwind and leading fiery device 26, described upper whirlwind is led fiery device 26 and is arranged along same even circumferential by leading fiery blade 28 on multiple, and the height that upper whirlwind is led fiery device 26 equates with the height of leading fiery wall 23.On lead fiery blade 28 and be crescent shape, quantity is 20 of 10 –, its Breadth Maximum is 10mm – 25mm, and on to lead fiery blade horizontal sextant angle 281 be that 30 Du – 45 spend.

On the inwall of cylindricality combustion chamber 22, be provided with lower whirlwind and lead fiery device 27, described lower whirlwind is led fiery device 27 and is arranged along same even circumferential by leading fiery blade 29 under multiple, and the height that described lower whirlwind is led fiery device 27 is 1/3 – 1/2 of cylindricality combustion chamber 22 height.Under lead fiery blade 29 and be crescent shape, quantity is 20 of 10 –, its Breadth Maximum is 10mm – 25mm, and under to lead fiery blade horizontal sextant angle 291 be that 30 Du – 45 spend.

On lead fiery blade 28, under lead fiery blade 29 and be all crescent shape, in the middle of wide two ends narrow, thereby, described Breadth Maximum refer to lead fiery blade 28, under lead the width of fiery blade 29 the widest part.

On lead fiery blade horizontal sextant angle 281: refer to the angle of leading between fiery blade 28 and horizontal plane.

Under lead fiery blade horizontal sextant angle 291: refer to down the angle of leading between fiery blade 29 and horizontal plane.

While leading fiery device without whirlwind, high-temperature flue gas and flame that burning produces directly upwards jump on the bottom of a pan, burn abundant not; When only establishing a whirlwind and leading fiery device, although extended the time of staying of high-temperature flue gas in stove, be not sufficient to make high-temperature flue gas fully to burn.The design leads after fiery device having possessed two-layer whirlwind, the high-temperature flue gas that burning produces and flame are first led fiery device 27 rotations along lower whirlwind and are risen, enter and lead fiery wall 23 by taper combustion-supporting 21, high-temperature flue gas and the flame of rotation accelerates rotation vertical leading under the effect that fiery wall 23 and upper whirlwind lead fiery device 26, owing to leading, fiery wall 23 diameters are less, the ascending air pilot flame that burning produces sprays from leading fiery wall 23, the vertical lifting the bottom of a pan of going directly.Because the present invention possesses, upper whirlwind is led fiery device 26 and lower whirlwind is led fiery device 27, both cooperatively interact and can greatly extend the time of staying of high-temperature flue gas in stove, impel burning velocity to slow down, thereby make the materials such as fuel gas in charcoal and the flue gas in fuel, solia particle, tar be able to abundant burning, reduce the concentration of emission of the harmful substances such as the flue dust that burning produces, sulfur dioxide, nitrogen oxide, carbon monoxide, environmental protection more, safety.

2, air intake and smoke evacuation:

The present invention has two air intake passages, is respectively air intake passage and secondary air passage.

The entrance of an air intake passage is grey chamber 5, adjusts the intake of an air intake by adjusting drawer 51 positions.It is burning oxygen supply that an air intake directly enters thorax 2 in stove from grey chamber 5 through fire grate 3.

The entrance of secondary air passage is the secondary air inlet 12 of furnace external chamber 1 below, and secondary air is in secondary air inlet 12 enters furnace external chamber 1, stove the secondary air duct 11 between thorax 2, and being entered in stove by the combustion air hole 24 on 2 outer walls of thorax in stove is burning oxygen supply in thorax 2.

Combustion air hole 24 comprises upper air inlet hole 241, middle fresh air inlet 242 and lower fresh air inlet 243.First, provide oxygen by being uniformly distributed in lower fresh air inlet 243 on cylindricality combustion chamber 22 for the comburant in cylindricality combustion chamber 22, the high-temperature flue gas mixture that burning forms is led at lower whirlwind under the effect of fiery device 27, rotation is risen and is entered taper combustion-supporting 21, then, continue as burning oxygen supply by the middle fresh air inlet 242 on taper combustion-supporting 21, finally, high-temperature flue gas mixture continues to rise to enter to lead fiery wall 23, be burning oxygen supply by upper air inlet hole 241 again, due to upper air inlet hole 241 with on lead fiery blade 28 intervals and arrange, high-temperature flue gas mixture is led under the acting in conjunction in fiery device 26 and upper air inlet hole 241 at upper whirlwind after entering and leading fiery wall 23, can not only accelerate rotation, and can be more even with oxygen mix, impel burning more abundant.Owing to leading, fiery wall 23 diameters are less, the ascending air that burning produces can spray from leading fiery wall 23 by pilot flame, the vertical lifting the bottom of a pan of going directly, now, high-temperature flue gas mixture can not directly enter flue 13 under the effect of arc fire blocking plate 15, and on stove, frame has pan, make furnace inner space relative closure, high-temperature flue gas can only burn away in stove, until sufficient combustion, the gas after fully burning could enter flue 13 from smoke input chamber 18 and discharge.The design of leading fiery wall 23 can make the flame the bottom of a pan of going directly, and has increased the heating surface area in the bottom of a pan, has extended the time of staying of high-temperature flue gas in kitchen range, has improved temperature in kitchen range.The design of arc fire blocking plate 15 has reduced flame and flue gas loss, make the materials such as fuel gas in charcoal and the flue gas in fuel, solia particle, tar be able to abundant burning, free from environmental pollution, the heat major part that burning produces is absorbed and used, and effectively avoids that fuel unburned is complete just to run off from flue.

3, pot circle 4:

Pot circle 4 comprises cauldron circle 41, middle pot circle 42 and fire sealing cover 43, and cauldron circle 41 is donut structure with middle pot circle 42, and fire sealing cover 43 is disc-shaped, and three cooperatively interacts, and can adapt to the pan of different sizes.When stove is only when warming oneself, cover fire sealing cover 43 and can make the inner space that forms a relative closure of stove, slow down burning velocity, extend the heating time.

4, reinforced and collection ash:

Charge door 6 is communicated with thorax 2 and furnace external chamber 1 in stove, it is larger that charge door 6 designs, when reinforced, open reinforced lid 61 and just can put into fuel, fuel tumbles on fire grate 3 along cinder catcher 31, ashes remaining after completing combustion drop on the drawer 51 of grey chamber through fire grate 3, pull out drawer 51 and outwell ashes wherein when cleaning.
