For exhaust end.Inner cylinder 2 is arranged on the inside of outer barrel 1, can limit shape between inner cylinder 2 and outer barrel 1 with the concentric setting of outer barrel 1
Into space be configured to annular inlet chamber, annular inlet chamber is connected with the inlet end of inner cylinder 2, i.e., the gas in annular inlet chamber can
Entered by the inlet end of inner cylinder 2 in inner cylinder 2.
Secondary inlet pipe 5 is arranged in annular inlet chamber and at the exhaust end of inner cylinder 2, and secondary inlet pipe 5 is along inner cylinder
2 outer wall circumferentially extending, secondary inlet pipe 5 is provided with multiple steam vents, for injecting gas into annular inlet chamber；One is grading
The exhaust end of tracheae 3 is inserted in the inlet end of inner cylinder 2, and the part primary air inlet pipe 3 for being inserted into inner cylinder 2 can be same with inner cylinder 2
Axle center is set；One-level spray bar 4 is arranged in one-level air inlet pipe 3, and the fuel-oil atmozation hole of one-level spray bar 4 is substantially in inner cylinder 2
Inlet end at, the fuel-oil atmozation hole of the one-level spray bar 4 is generally also provided with igniter, for making ejection in one-level spray bar 4
The gas discharged of fuel and one-level air inlet pipe 3 occur combustion reaction in inner cylinder 2；Two-stage oil feeding pipe is arranged on the interior of inner cylinder 2
Portion and the top for being located at one-level air inlet pipe 3, the preferably overall helical structure of two grades of spray bars 6, and two grades of spray bars 6
Multiple fuel-oil atmozation holes are provided with, so that fuel is fully mixed with air-flow, moreover, two-stage oil feeding pipe 6 is close to preferably close to interior
The inwall of cylinder 2 is set, and the region residing for fuel gas that such two grades of spray bars 6 spray more can be with the inwall along inner cylinder 2
The position of the air-flow flowed up is corresponding, is burnt near the inwall of inner cylinder；Certainly, two grades of spray bars 6 can also be distribution
In on the whole cross section of inner cylinder 2, and multiple fuel-oil atmozation holes only are being opened up at the inside of inner cylinder, so can also be main
By fuel injection near the inwall of inner cylinder, and then it is used to make to be heated positioned at two grades of the part spray bar 6 of inner cylinder middle section, more
Be conducive to evaporation, the atomization of its inner fuel；So may be used towards the inlet end of inner cylinder 2 in fuel-oil atmozation hole on two grades of spray bars 6
With the flame gas formed with one-level spray bar 4 and the formation convection current of the gas from secondary inlet pipe 5, to lift mixed effect,
The flame ignition that the fuel that two grades of spray bars 6 spray is sprayed by one-level spray bar 4, and mainly with the gas in annular inlet chamber
Combustion reaction occurs for body.
When carrying out combustion test, on the one hand, the fuel that one-level oil inlet pipe sprays around it by one-level air inlet pipe 3 with being sprayed
Combustion reaction occurs for the gas come, combustion flame is formed in inner cylinder 2, but collect the fuel sprayed after all by one-level spray bar 4 more
In in the center of inner cylinder 2, so the flame that one-level spray bar 4 is formed also is concentrated mainly on the center of inner cylinder 2, the one-level oil spout
The flame that pipe 4 is formed may also pass through eddy flow, the structure such as speed reduction screen, flame concentration problem is improved, expands flame model
Enclose.
On the other hand, the gas that secondary inlet pipe 5 sprays makes the air pressure in annular inlet chamber after annular inlet chamber is entered
Rise, and because annular inlet chamber is also connected by the inlet end and the inner space of inner cylinder 2 of inner cylinder 2, so annular inlet chamber
In gases at high pressure have to be entered in inner cylinder 2 by the inlet end of inner cylinder 2, the gas entered in inner cylinder 2 is along inner cylinder 2 and one
Circular passage between level air inlet pipe 3 is flowed up, not only can be to being sprayed from one-level after flowing in the upper space of inner cylinder 2
The fuel formation afterburning that oil pipe 4 is imperfect combustion, also primarily to being mixed and by one with the fuel that two grades of spray bars 6 spray
The flame ignition that is formed of level spray bar 4, and in the process, due to the part primary air inlet pipe 3 that is inserted into inner cylinder 2 with it is interior
The guide functions of the circular passage formed between cylinder 2, the above-mentioned gas in annular inlet chamber is mainly along inner cylinder 2
Inwall is flowed up, and the fuel finally sprayed in the upper space of inner cylinder 2 at the region of cylinder inwall with two grades of spray bars 6 is formed
Burning, has thus filled up the weaker defect respectively of flame at the fringe region in inner cylinder 2, the fire formed with one-level spray bar 4
Flame is engaged, and makes the flame distribution in inner cylinder 2 uniform, it is ensured that the heating-up temperature at diverse location is more uniformly distributed, so as to
Uniform heating is not only formed to the experiment at the exhaust end of outer barrel 1, to obtain accurate heat-resistance test data.
Further, since the gas temperature that secondary inlet pipe 5 sprays is relatively low, if the gas of this low temperature is directly discharged into inner cylinder
The fuel mixed combustion sprayed in 2 upper space, with two grades of spray bars 6, it is initial that meeting greatly two grades of spray bars 6 of suppression spray
Combustion rate, is additionally, since that two grades of spray bars 6 are closer to the distance apart from the exhaust end of outer barrel 1, i.e., the fuel that two grades spray bars 6 spray
The distance of the gas mixing after-combustion sprayed with secondary inlet pipe 5 is shorter, under the influence of this double factor, can make two grades of oil spouts
The burning for the fuel that pipe 6 sprays is extremely insufficient, therefore can hardly reach the effect that uniform heating surface is formed at the opening of outer barrel 1
Really.

Degree, and it is beneficial to the service life of extension inner cylinder 2.
Wherein, the internal diameter of inner cylinder 2 is preferably gradually increased by inlet end to exhaust end, i.e., inner cylinder 2 is generally a butt
Pyramidal structure, the fuel that one-level spray bar 4 sprays is typically radial, and the fuel of ejection is that surrounding comes from one-level air inlet pipe 3
Gas burning during, the volumetric expansion of mixed gas finally reaches larger heating surface at the exhaust end of outer barrel 1
Product, to meet the heat-resistance test requirement to large-scale material.
Further, the steam vent on secondary inlet pipe 5 is set preferably towards inner cylinder 2, because the barrel of inner cylinder 2 is cone
Face structure, so after the gas of the steam vent ejection on secondary inlet pipe 5 is on the outer wall for blowing to inner cylinder 2, being made by inclined-plane
With the outer wall that may proceed to downwards and be close to inner cylinder 2 flows, and thus can further improve heating of the outer wall to gas of inner cylinder 2
Effect, can also improve the cooling effect to inner cylinder 2.
Gas flow direction on, be inserted into the inlet end of inner cylinder 2 the air inlet pipe of part first internal diameter be preferably by
It is cumulative big, be so not only more suitable for the burning for the fuel that one-level spray bar 4 is sprayed, but also can be with inner cylinder 2 formation phase

Space structure, by inwall from the air flow guiding in annular inlet chamber to inner cylinder 2.
The inlet end of outer barrel 1 is connected by first annular baffle plate 11 with the outer wall of one-level air inlet pipe 3, first annular baffle plate 11
There is gap between the inlet end of inner cylinder 2, connection is so on the one hand established between one-level air inlet pipe 3 and outer barrel 1 and is closed
System, is relatively fixed the two, but also self-assembling formation is used to make annular air inlet between the inlet end of a ring baffle and inner cylinder 2
The passage that gas in chamber is entered in inner cylinder 2.
The exhaust end of inner cylinder 2 is connected by the second ring baffle 12 with outer barrel 1, so both can inner cylinder 2 and outer barrel 1 it
Between set up annexation, be relatively fixed the two, can also be by the closed upper part of annular inlet chamber.
The middle part of inner cylinder 2 is preferably connected by the 3rd ring baffle 13 with outer barrel 1, on the 3rd ring baffle 13 and is leaned on
Multiple passages are offered at the outer wall of nearly inner cylinder 2, multiple passages are circumferentially arranged along the 3rd ring baffle 13, the passage
Preferably elongated hole-shape structure, to possess more preferably by property；3rd ring baffle 13 can both be strengthened between inner cylinder 2 and outer barrel 1
