By the structural feature that supplies further to understand the utility model, application technology means and the effect reached of expection, now the occupation mode of the utility model is narrated, believing to have more deeply and concrete understanding the utility model, is described below:

See also Fig. 2 to shown in Figure 4, the self-heating gas high-temp combustion device of the utility model is for deriving gas and air respectively by gas pipe 213 and air hose 214 earlier; The air that this air hose 214 is derived can pass through air spiral ribs 2141 and produce the air-flow of a rotation, and simultaneously, the gas that this gas pipe 213 is derived can produce a radial air flow via this openend grooving 2131; Then be directed to this spiral ribs 2132 again and make this gas also generate swirling eddy, these two strands of swirling eddies can make air and gas can produce the good mixing effect, and the air velocity after mixing is accomplished is about 70 ~ 150m/s and is directed to this guide port 212; And light the gas that this premix is accomplished through igniter 22, after the igniting, gas can be led to this guide port 212 and be conducted in this pre-burning unit 23; Wherein this guide wire 2121 can be concentrated gas and be directed in this pre-burning unit 23, avoids the air-flow sinuous flow, after air-flow is directed in the pre-burning unit 23; The aflame gas that has the part flow in the cushion space 2311 and burns slowly, becomes guiding flame (Pilot) burning, heating, simultaneously; Most gas can burn toward combustion chamber 232 in, because of the caliber of combustion chamber 232 caliber greater than guide port 212, so except the combustion gas of central authorities fail to be convened for lack of a quorum guide forward; The combustion gas of all sides is known from experience generation one gyration airflow, makes combustion-gas flow can carry out the effect that a burning heats up in this combustion chamber 232, so; After combustion-gas flow advances to this fireworks outlet 233; Can be with the flame tail ejection of a high temperature, the guiding lip 2331 of this fireworks outlet 233 can make this flame tail concentrate ejection, through the effect of this device; Making combustion-gas flow can in combustion chamber 232, carry out pre-burning earlier heats up; The flame tail of terminal high temperature then can be by these fireworks outlet 233 ejections, and the speed that combustion chamber 12 temperature in this stove and accessory 10 are raise promotes, and increases the efficient of stove and accessory 10.

In addition, see also shown in Figure 5, when this self-heating gas high-temp combustion device 20 is lighted; The parallel airflow of a HTHP can be produced, after air-flow is sprayed by this fireworks outlet 233, the guidance part 31 of other side guide unit 30 can be sprayed to; This guidance part 31 can become uprush with the air-flow guiding conversion direct of travel of fireworks outlet 233 ejections, and then, this vertical gas fails to be convened for lack of a quorum and flows to this supplemental pilot unit 50; Through the supplemental pilot portion 51 of this supplemental pilot unit 50, air-flow is further turned to again and make air-flow can produce a good circulation in the chamber 12, in addition in combustion; Local air-flow then can flow toward this opening 13; And then be directed in this flue 40, making can be through the guide functions of guide unit 30 and this supplemental pilot unit 50 by the air-flow of this fireworks outlet 233 ejections, makes this air-flow can in stove and accessory 10, carry out a good circulation; Can increase the efficiency of combustion of sintering furnace, and combustion 12 inside, chamber are heated evenly.

In addition, like Fig. 6 and shown in Figure 7, when this inductor 91 is sensed capacity in the stove and accessory 10 when little; Can pass through this this second valve 72 of second driver, 932 interlocks, and then this second smoke guide port 62 is opened, if sense the exhaust quantitative change when big; Then can select to drive this this first valve 71 of first driver, 931 interlocks this first smoke guide port 61 is opened relatively,, then can relatively this first smoke guide port 61 and second smoke guide port 62 be opened simultaneously if when capacity increases again; To obtain a bigger capacity person, see through the induction of inductor 91 and can drive these drivers 93, in addition to obtain a preferable exhaust effect; Please cooperate and consult shown in Figure 1ly, the air guide port 81 of these chimney 80 bottoms can be opened when flue gas velocity is too fast; Import local air, to relax the speed of smoke evacuation.

The above person is merely a preferable possible embodiments of the utility model, changes so use the equivalent structure that patent specification and claim do such as, ought to be included in the protection domain of this patent.
