Lead fiery blade horizontal sextant angle 291 down: be meant down the angle of leading between fiery blade 29 and the horizontal plane.
When no whirlwind was led fiery device, high-temperature flue gas and flame that burning produces directly upwards jumped on the bottom of a pan, and it is abundant inadequately to burn; When only establishing a whirlwind and leading fiery device,, be not sufficient to make high-temperature flue gas fully to burn though prolonged the time of staying of high-temperature flue gas in stove.The design is after having possessed two-layer whirlwind and having led fiery device; High-temperature flue gas that burning produces and flame are led fiery device 27 rotations along following whirlwind earlier and are risen; Get into through taper combustion-supporting 21 and to lead fiery wall 23, the high-temperature flue gas of rotation quickens down to rotate with the effect that last whirlwind is led fiery device 26 at the vertical fiery wall 23 of leading with flame, and is less owing to leading fiery wall 23 diameters; The ascending air pilot flame that burning produces is from leading fiery wall 23 ejections, the vertical lifting the bottom of a pan of going directly.Last whirlwind is led fiery device 26 and following whirlwind is led fiery device 27 because the present invention possesses; Both cooperatively interact and can prolong the time of staying of high-temperature flue gas in stove greatly; Impel burning velocity to slow down; Thereby make materials such as charcoal and the fuel gas in the flue gas in the fuel, solia particle, tar be able to abundant burning, having reduced emission of harmful substances concentration 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 inlet of an air intake passage is grey chamber 5, adjusts the intake of an air intake through adjustment drawer 51 positions.Air intake gets into directly through fire grates 3 from grey chamber 5 that thorax 2 is the oxygen supply of burning in the stove.
The inlet of secondary air passage is the secondary air mouth 12 of furnace external chamber 1 below, and secondary air gets in furnace external chambers 1, the stove behind the secondary air duct 11 between the thorax 2 from secondary air mouth 12, is got into by the combustion air hole on 2 outer walls of thorax in the stove 24 to be the burning oxygen supply in the stoves in the thorax 2.
Combustion air hole 24 comprises fresh air inlet 241, middle fresh air inlet 242 and following fresh air inlet 243.At first, for the comburant in the cylindricality combustion chamber 22 oxygen is provided by the following fresh air inlet 243 that is uniformly distributed on the cylindricality combustion chamber 22, the high-temperature flue gas mixture that burning forms is led under the effect of fiery device 27 at following whirlwind; Rotation is risen and is got into taper combustion-supporting 21, then, continues as the burning oxygen supply by the middle fresh air inlet 242 on the taper combustion-supporting 21; At last; The high-temperature flue gas mixture continue to rise gets into leads fiery wall 23, is the burning oxygen supply by last fresh air inlet 241 again and since last fresh air inlet 241 with on lead fiery blade 28 and be provided with at interval; The high-temperature flue gas mixture is led under the acting in conjunction of fiery device 26 and last fresh air inlet 241 at last whirlwind after getting into and leading fiery wall 23; Can not only quicken rotation, and can be more even with oxygen mix, impel burning more abundant.Because it is less to lead fiery wall 23 diameters, the ascending air that burning produces can pilot flame from leading fiery wall 23 ejections, the vertical lifting the bottom of a pan of going directly; At this moment, the high-temperature flue gas mixture can not directly get into flue 13 under the effect of arc fire blocking plate 15, and frame has pan on the stove; Make the furnace inner space relative closure; High-temperature flue gas can only burn away in stove, and until sufficient combustion, fully the gas after the burning could get into flue 13 discharges from smoke input chamber 18.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 prolonged the time of staying of high-temperature flue gas in kitchen range, has improved temperature in the kitchen range.The design of arc fire blocking plate 15 has reduced flame and flue gas loss; Make materials such as charcoal and the fuel gas in the flue gas in the 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 the fuel unburned to finish and just runs off from flue.
