Face is provided with outer inclined-plane inwardly and downwards, which is equipped with several inner convex platforms 12 being spaced each other.Preferably, this implementation
A part of the inner convex platform 12 of example is arranged on the outer wall 10B of inner ring air cavity 120 and protrudes from outer wall 10B, another part setting
In outer inclined-plane and protrude from outer inclined-plane.
Further, outer lug boss 11 and the quantity of inner convex platform 12 are at least three.In the present embodiment, outer lug boss 11 and interior
The quantity of boss 12 is preferably four.
As shown in Fig. 3-4 and Fig. 6, the lower surface of outer fire cover 20A is equipped with several first outer grooves 21 being spaced each other and the
Two outer grooves 22.Further, the width of the first outer groove 21 and the second outer groove 22 is all larger than the width of outer lug boss 11, while outside first
The depth H of slot 211The depth H of the second outer groove of < 222The height of < outer lug boss 11, with this, outer lug boss 11 and the first outer groove 21 and/
Or second outer groove 22 when being staggeredly located out or matching, outer fire cover 20A matches the gap to form different height with distributor 1
3, make burner for the fire hole parameter of three kinds of different gaps 3, the outlet gap for breaking through existing burner is fixed and invariable
Bottleneck enables burner to be suitable for different gas sources or different thermic load, improves adaptability, and guarantees fuel gas high efficiency, steady
Fixed burning.
Further, the quantity of the second outer groove 22 is equal with the quantity of the first outer groove 21.First outer groove 21 and the second outer groove
22 are arranged in pairs, i.e., each pair of first outer groove 21 and the two in the second outer groove 22 are close to each other, with this, rotate outer fire cover by a small margin
20A, i.e., the mated condition of changeable outer lug boss 11 and the first outer groove 21 and/or the second outer groove 22, and then realize change burning
3 parameter of outlet gap of device, convenient for quickly adjusting.
In the present embodiment, the quantity of the first outer groove 21 and the second outer groove 22 is four.
As shown in Fig. 3 and Fig. 5-6, the lower surface of inner fire cover 20B is equipped with several first inside grooves 23 being spaced each other and the

The depth h of slot 231The depth h of the second inside groove of < 242The height of < inner convex platform 12 changes inner convex platform 12 and two outer grooves with this
When relative position, inner fire cover 20B matches the gap 4 to form different height with distributor 1, make burner with have three kinds not
Same inner ring outlet gap 4, keeps the adaptation range of same burner bigger, is conducive to generalization, the standardization of burner, from
And reach reduction manufacture and maintenance cost.
Illustrate the working principle of the present embodiment below with reference to Fig. 6-10:
As shown in fig. 6, the outer lug boss 11 of distributor 1 and the position of the first outer groove 21, the second outer groove 22 are staggered, this
When, it is L that outer fire cover 20A, which is matched with distributor 1 and to be formed gap 3,1The first outer fire hole, the fire hole face of the first outer fire hole
Product S1=π × D1×L1, D in formula1For the outer wall 10A interior diameter of outer ring air cavity 110.The similarly inner convex platform 12 and first of distributor 1
Position when being staggered of inside groove 23, the second inside groove 24, it is L that inner fire cover 20B, which is matched with distributor 1 and to be formed gap 4,1The of '
A kind of interior fire hole, the fire hole area S of the first interior fire hole1'=π × d1×L1', d in formula1For the outer wall of inner ring air cavity 120
10B interior diameter.
As Figure 7-8, outer lug boss 11 is matched with the first outer groove 21, outer fire cover 20A is matched with distributor 1 to be formed between
Gap 3 is L2Second of outer fire hole, the fire hole area S of this second outer fire hole2=π × D1×L2.Similarly, when inner convex platform 12 with
When first inside groove 23 matches, it is L that inner fire cover 20B, which is matched with distributor 1 and to be formed gap 4,2Second of ' (not shown)
Interior fire hole, the fire hole area S of fire hole in this second2'=π × d1×L2'.
As shown in figs. 9-10, outer lug boss 11 is matched with the second outer groove 22, and outer fire cover 20A matches to be formed with distributor 1
Gap 3 is L3The third outer fire hole, the fire hole area S of the third outer fire hole3=π × D1×L3.Similarly, when inner convex platform 12
When matching with the second inside groove 24, it is L that inner fire cover 20B, which is matched with distributor 1 and to be formed gap 4,3The third of ' (not shown)
Fire hole in kind, the fire hole area S of the third interior fire hole3'=π × d1×L3'.
Further, L1> L2> L3, and L1=H1+L2=H2+L3.Similarly, L1' > L2' > L3', and L1'=h1+
L2'=h2+L3'.
In the present embodiment, L1Preferably 1.45mm, L2Preferably 1.3mm, L3=it is preferably 0.8mm, D1Preferably
112mm.Assuming that rated heat input, rated heat load takes 4.8kw, outer ring thermic load is 3.84kw, then the area S of the first outer fire hole1=
509.9mm2, thermal intensity of fire port q1=7.53w/mm2, it is adapted to natural gas.The area S of second of outer fire hole2=457.2mm2, fire
Hole calorific intensity q2=8.4w/mm2, it is adapted to liquefied gas.The area S of second of outer fire hole3=281.3mm2, thermal intensity of fire port q3=
13.65w/mm2, it is adapted to artificial coal gas.
As it can be seen that making fire hole parameter change by the mated condition for changing boss and different depth recess, guarantee burning
Device is adapted to different gas sources, to reach efficient, stablize the purpose of burning.
Similarly, by changing L1、L2、L3Parameter, burner can also be made to adapt to the different thermic loads under same gas source, from
And reaches efficient, stablizes the purpose of burning.
Embodiment 2
The present embodiment is with embodiment 1 the difference lies in that the setting position of inside groove and inner convex platform 12 is exchanged.Specifically, interior
The lower surface of fire cover 20B, which is provided with, to be spaced each other and several symmetrical flanges.The upper surface outer wall 10B of inner ring air cavity 120 is set
There are several first grooves being spaced each other and the second groove, the first groove and the second groove are adapted to match with flange.Into
One step, the width of the first groove and the second groove are respectively greater than the width for being equal to flange, and the depth < of the second groove the
The height of the depth < flange of the second groove of depth < of the height or the first groove of the depth < flange of one groove.
Embodiment 3
If the present embodiment is with embodiment 1 the difference lies in that the lower surface of outer fire cover 20A and/or inner fire cover 20B are additionally provided with
The dry third groove being spaced each other, wherein the quantity of third groove is equal with the quantity of the first outer groove 21 or the first inside groove 23.
Third groove is arranged in pairs with the first outer groove 21 or the first inside groove 23.Further, the width of third groove is greater than outer lug boss
The width of 11 width or the width of inner convex platform 12 or flange, and the depth of third groove is less than the depth H of the first outer groove 211
Or first inside groove 23 depth h1Or second groove depth.Its position is same as Example 1.When boss and different depth
When being staggeredly located out or matching with any groove of groove, outer fire cover 20A and/or inner fire cover 20B can match with distributor 1
The fire hole that conjunction forms different height gap is realized burner and had not only been adapted to different gas sources with this, but also is adapted to negative in different heat
Lotus, it is versatile, be conducive to burner standardization and large-scale production.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
