Specifically, as shown in figure 4, a boss 56, cooling jacket 34 are extended in the top of combustion head outer wall 54 laterally
Top be fixedly attached to the outer rim of boss 56, such as weld.It is spaced between cooling jacket 34 and combustion head outer wall 54 to be formed
Coolant flow channel 44, cooling jacket 34 are collectively forming circumferentially arranged with some windows 58 through cooling jacket 34, some windows 58
The air intake 30 of air flow channel 28.
In an illustrated embodiment, some windows 58 are arranged at the top of cooling jacket 34.Each window 58 is rectangle,
Some windows 58 are evenly spaced setting along cooling jacket 34 is circumferential, and a cut-off portion is provided between every two adjacent windows 58
59.The cooling structure includes some radiating rib plates 60 being arranged between cooling jacket 34 and combustion head outer wall 54, radiating ribs
Plate 60 is exchanged heat to suck between the air of window 58 and radiating rib plate 60, so as to realize to the cold of combustion head 10
But, each radiating rib plate 60 is positioned at a corresponding position of window 58.In this embodiment, axle of each radiating rib plate 60 along burner
To arrangement, and, each radiating rib plate 60 vertical with the inwall of combustion head outer wall 54 and cooling jacket 34 simultaneously of radiating rib plate 60
In the centre position of corresponding window 58 in the circumferential.
In the present embodiment, some heat emission holes 62 are provided with each radiating rib plate 60, increase the surface area of radiating rib plate, from
And promote radiating.
As shown in Figure 5 and Figure 6, in the embodiment shown in Fig. 5 and Fig. 6, it is contemplated that burner is in burning, combustion head 10
The temperature on top is higher than the temperature of bottom, and therefore, the cooling demand on the top of combustion head 10 is eager to excel than the bottom of combustion head 10.For reality
The now demand, some windows 58 are designed as to be in inverted trapezoidal in the present embodiment so that window 58 is tapered from top to bottom, thus makes
More air can be sucked by obtaining the top of window 58, be cooled down with combustion head outer wall 54 top higher to temperature.Shown here
Inverted trapezoidal is a kind of citing, can also use other tapered shapes.In the present embodiment the other structures of burner with it is upper
It is identical to state embodiment, will not be repeated here.
During work, the spray fuel gas of nozzle 14 causes air flow channel 28 and the bottom of nozzle 14 to form certain vacuum, by
Normal temperature air outside negative pressure, combustion head 10 is inhaled into coolant flow channel 44 through window 58, and air passes through the He of radiating rib plate 60
Coolant flow channel 44, by heat convection take away the inwall of combustion head 10 be transmitted through come heat, to be cooled down to combustion head 10,
Improve the working environment of combustion head 10.
The present invention's remains the advantage of injection burner from cooling injection burner, and adds again for burning
First 10 refrigerating function.The augmentation of heat transfer of radiating rib plate 60 is set, combustion-supporting air is participated in and first take part in cooling to combustion head 10,
Participate in burning again.So that the gaseous mixture enthalpy in mixing tube 12 improves, the stability of burning was both improved, has extended combustion head again
10 service life, reduce radiation of the combustion head 10 to environment.Moreover, radiating rib plate 60 is connected to cooling jacket 34 and combustion head
Structural support can be formed between outer wall 54, the fixed effect of support is played to cooling jacket 34 so that cooling structure is more steady
Gu.
It should be appreciated that in an illustrated embodiment, window 58 is designed as rectangle and inverted trapezoidal, but the present invention ought not
As limit, in other embodiments, window 58 can also be designed as to other shapes according to the actual requirements, for example, ellipse or
Circular and other shapes combinations.
It should also be understood that the set-up mode of above-mentioned radiating rib plate 60 is only one embodiment of the present invention, at it
In his embodiment, according to the specific design demand of burner, radiating rib plate 60 can also be set with other mounting means, such as will
Radiating rib plate 60 is designed as having certain angle with cooling jacket 34 and combustion head outer wall 54.
For the fixation of chuck 26, in an illustrated embodiment, using in absorption tube chuck portion 50 and corresponding absorption tube
Some screws are set on 22, recycle screw to fix.Similarly, some spiral shells are set close to one end of combustion head 10 in mixing tube 12
Hole, while set same amount of screw in the mixing tube chuck portion 36 of correspondence position, profit is screwed, so as to by chuck
26 are fixed on burner.Certainly, in other embodiments, chuck 26 can also be fixed on burning using other fixed forms
On device, the present invention is not limited this.
In summary, the present invention is proposed a kind of from cooling injection burner, and air ejection mouth is arranged on outside combustion head
All portions.By adding a chuck to form the air flow channel that one end is closed all the way to whole burner, cooling is provided with outside combustion head
Structure, cooling structure include cooling jacket, coolant flow channel are formed between cooling jacket and combustion head outer wall, and cooling jacket is provided with
The air intake connected with coolant flow channel.Operation fuel nozzle sprays high velocity fuel gas, and nozzle bottom and air flow channel are made
Into certain vacuum degree, air is inhaled into outside combustion head to be entered the mixing tube of burner along coolant flow channel and is mixed with fuel gas
Conjunction sprays burning again.Combustion head inner flow passage is thermal-flame, is normal temperature air outside combustion head.Air is flowed through outside combustion head
Radiating rib plate on wall and outer wall takes away amount of heat by heat convection and combustion head is cooled down.Because the present invention will be used for
Combustion-supporting air introduces combustion head and is used as combustion-supporting again after cooling, and the advantage for remaining injection burner adds combustion head again
Cooling, had not only improved the stability of burning but also had extended the service life of combustion head, reduced radiation of the burning head to environment.
Concepts described herein may be embodied to other forms in the case of without departing from its spirit and characteristic.It is disclosed
Specific embodiment should be considered as exemplary rather than restricted.Therefore, the scope of the present invention be by appended claim,
Rather than it is determined according to these descriptions before.Any change in the letter of claim and equivalency range is all
