Type or by being welded together, it uses mould that need not be complicated when being integrally formed to cast fire hole, in addition, the bar is stitched
Formula extroversion fire hole passage 14 is tilted upward from the annular fuel gas chamber 10 to the lateral wall direction of external ring fire cover body 1, is easy to
Heating to top heated object, and the export-oriented opening of the export-oriented fire hole passage 14 of the slit-aperture type is formed in the external ring fire cover sheet
On the lateral wall of body 1, it is easy to convenient to the slit-aperture type when outside air of external ring fire cover body 1 is flowed up during burning
The upper flame of the export-oriented export-oriented opening of fire hole passage 14 carries out auxiliary air supplement, is conducive to combustion gas fully to burn, improves the thermal efficiency.
As described above, when it is implemented, the extroversion that the dowel 13 is located at the export-oriented fire hole passage 14 of the slit-aperture type is opened
Within mouthful, the export-oriented opening of the export-oriented fire hole passage 14 of some slit-aperture types is linked to be annular export-oriented opening, in this way, it is conducive to mitigating
The dowel 13 is to the compartmentation of the export-oriented fire hole passage 14 of adjacent two slit-aperture type, in this external ring fire cover sheet during in order to burn
Annular crater is formed on body 1, more uniform annular-heating is realized.
As described above, when it is implemented, the annular inboard wall body 15 of the external ring fire cover body 1 and the annular upper wall body
The slit-aperture type center communicated with the annular fuel gas chamber 10 is connected and is formed between the two between 11 also by dowel 13
To fire hole passage 16, the slit-aperture type center is to fire hole passage 16 from the annular fuel gas chamber 10 to the external ring fire cover body 1
Center position is tilted upward, and is easy to the heating to top heated object, the slit-aperture type center to the center of fire hole passage 16 to
Opening is formed on the ring heart side wall of the external ring fire cover body 1, the ring heart side air of external ring fire cover body 1 when being easy to burn
Auxiliary air when flowing up to the slit-aperture type center to from the center of fire hole passage 16 to opening flame is supplemented, and is conducive to combustion gas
Fully burning, improves the thermal efficiency, also, the export-oriented fire hole passage 14 of the slit-aperture type export-oriented opening and the slit-aperture type center to
The center of fire hole passage 16 is opposite to opening, during burning on slit-aperture type extroversion fire hole passage 14 flame and slit-aperture type center to fire hole
On passage 16 flame will not chiasma interference, be less prone to the underproof situation of Huang Yan, CO content.
As described above, when it is implemented, the dowel 13 is located at the slit-aperture type center to the center of fire hole passage 16
To within opening, some slit-aperture type centers are linked to be annular center to opening to the center of fire hole passage 16 to opening.In this way, its
Be conducive to mitigating the dowel 13 to compartmentation from adjacent two slit-aperture types center to fire hole passage 16, during in order to burn
Annular crater is formed on this external ring fire cover body 1, more uniform annular-heating is realized.
As described above, when it is implemented, the upper end of annular upper wall body 11 is provided with connected annular horizontal wall 110 and ring
Shape inclined wall 111, the annular inclined wall face 111 is set close to the annular inboard wall body 15 and it gradually inclines from inside to outside
Set obliquely, in this way, being conducive to the slit-aperture type center to the center of fire hole passage 16 to opening and the annular inclined wall face
Upper-side area between 111 upper ends is supplemented to the center of fire hole passage 16 to the auxiliary air of flame in opening slit-aperture type center.
As described above, when it is implemented, the slit-aperture type center to the inclination angle with respect to the horizontal plane of fire hole passage 16 at 25 °
Between~45 °, its direction is adapted to, and inclination maximum is 45 degree so that on the slit-aperture type center is open to fire hole passage 16 is export-oriented
Flame, which is tilted, to be sprayed, and it is difficult the stop by the annular upper wall body 11, and minimum angle-of-incidence is 25 degree, air-flow when it combines burning
The influence moved upwards so that the slit-aperture type center will not be heated to the upper flame of the export-oriented opening of fire hole passage 16 away from upside
Body.
As described above, when it is implemented, the slit-aperture type extroversion 14 inclination angle with respect to the horizontal plane of fire hole passage 25 °~
Between 45 °, its direction is adapted to, and inclination maximum is 45 degree so that got angry to opening at the export-oriented center of fire hole passage 14 of the slit-aperture type
Flame, which is tilted, to be sprayed, and it is difficult the stop by the annular upper wall body 11, and minimum angle-of-incidence is 25 degree, its combine when burning air-flow to
The influence of upper motion so that the export-oriented center of fire hole passage 14 of the slit-aperture type will not be heated to flame in opening away from upside
Body.
As described above, this case protection is a kind of fire cover on burner, all are same or like with this case structure
Technical scheme should all be shown as falling into the protection domain of this case.
