Description
Technical field
The present invention relates to premix metal burners, belong to field of combustion technology.
Background technology
Early in 20 beginnings of the century just it is proposed that the theory of pre-mixing gas combustion burning, but until 50 years 20th century
Generation, gas ceramic premix Multi-hole infrared ray burner just have large development.This burner pollutant emission is low, noise is small, combustion
It is big to burn intensity height, adjustable range.Ceramic body sends out far infrared radiation, for the fields such as dry.Metallic fiber is invented again later
Surface combustion burner manufactures combustion head with metallic fiber sintered or weaving manufacture hardware cloth.This metal fiber surface combustor
It is higher than the thermal shock resistance of ceramic body multi-orifice burner, long lifespan, anti-backfire.Due to the nitrogen oxidation of Metal Fibre Combustion
Object discharge is low, environmental requirement higher and higher today, is more paid attention to.Especially nearest Metal Fibre Combustion extensive use
In fields such as boiler, the industrial furnaces of low nox emission.But metal fiber surface combustor finds there is stifled ash in use
Phenomenon.
Invention content
To solve the problems, such as that the stifled ash of existing metal fiber surface combustor in use, the present invention use metal grid
Make premixed combustion head.Specifically adopt the following technical scheme that：
A kind of metal grid combustion head, it is characterised in that the combustion head is by lining barrel and the metal being arranged on the outside of lining barrel
Grid cylinder forms；With a metal wave band and a straight band of metal fit closely composition one group of metal tape, this group of metal tape from
One end of lining barrel starts, and the lateral surface along lining barrel circumferencial direction in lining barrel carries out helically coiling, metal wave band and gold
The zone face for belonging to straight band is each perpendicular to side and the axis of lining barrel, metal tape close-packed arrays, and coiling terminates to the lining barrel other end,
The metal grid auxiliary cylinder is formed on the outside of lining barrel.
Another technical solution of the present invention is：
A kind of metal grid combustion head, it is characterised in that the combustion head is by lining barrel and the metal being arranged on the outside of lining barrel
Grid cylinder forms；One group of metal tape of composition is fitted closely with a metal wave band and a straight band of metal, this group of metal tape
Length is identical with lining barrel length, and multigroup metal tape is placed in lining barrel lateral surface, length direction and the lining barrel axis of metal tape
To parallel, the zone face of metal wave band and the straight band of metal is perpendicular to the side of lining barrel, and each group metal tape is along lining barrel circumference side
To close-packed arrays, it is booked lining barrel lateral surface, forms the metal grid auxiliary cylinder on the outside of lining barrel.
Metal grid combustion head of the present invention is used for premix burner, and pre-mixing gas combustion is by lining barrel aperture, then passes through metal
Aperture on grid cylinder is reached on the outside of metal grid auxiliary cylinder and is burnt, and the stifled ash for not only solving metal fiber surface combustor is asked
The advantages that inscribing, while metal fiber surface combustor low-nitrogen oxide discharging, anti-backfire, small noise can be retained, structure letter
It is single at low cost, it is easily fabricated, there is very strong practicability.

Specific implementation mode
Embodiment one
As shown in Figs. 1-5, metal grid combustion head is made of lining barrel 2 and the metal grid auxiliary cylinder 1 being arranged in 2 outside of lining barrel.
Lining barrel 2 is the drum being rolled by thick 1.5mm stainless sheet steels, drum diameter 200mm, long 500mm, and top is thick with 1.0mm
Stainless sheet steel does bottom plate closing.Such as Fig. 5, laser, every 10mm, is used in 2 side of lining barrel along drum length direction and circumferencial direction
The aperture of a width 1mm, long 10mm are opened, opening length direction is axially parallel with bucket, and aperture is covered with lining barrel side.These apertures are used
Pass through in allowing pre-mixing gas combustion.Welded flange at lining barrel air inlet, for coupling with burner fan interface flange.Such as Fig. 3, gold
It is Thin Stainless Steel narrowband, thick 0.5mm, wide 10mm to belong to directly band 1-2 materials.Such as Fig. 2, metal wave band 1-1 materials are Thin Stainless Steel
Narrowband, thick 0.5mm, wide 10mm, using equilateral triangle wave, equilateral triangle length of side 2mm.By a metal directly band 1-2 and
A piece metal wave band 1-1 is fitted closely, and the mode of fitting is that the angle of wave band and straight band zone face fit, and one group of composition has hole
Metal tape, keep the straight band of metal and metal wave band zone face and lining barrel side and axis it is vertical, opened from lining barrel one end
Begin, by this group of metal tape along lining barrel circumferencial direction helically coiling in the lateral surface of lining barrel 2, often encloses arrangement of combining closely, around
It makes 2 other end of lining barrel to terminate, metal grid auxiliary cylinder 1 is formed in 2 outside of lining barrel.Two endpoints of coiling use welding manner
It is fixed.Fig. 4 is metal grid auxiliary cylinder expanded schematic diagram.The combustion head of the metal grid auxiliary cylinder as pre-mixing gas combustion burner.In advance
Mixed combustion gas penetrates laser aperture inside lining barrel, comes out, is firing into the grid aperture of metal grid auxiliary cylinder, then from grid aperture
Burn burning on the outside of head.
Embodiment two
The present embodiment and embodiment one the difference is that, metal grid auxiliary cylinder be not formed by one group of metal tape helically coiling, and
It is to be rearranged by multigroup metal tape.
As shown in fig. 6, fitting closely one group of metal tape of composition, fitting side with a metal wave band and a straight band of metal
Multigroup metal tape is placed in lining barrel lateral surface as in the first embodiment, the length of this group of metal tape is identical with lining barrel length by formula, gold
The length direction for belonging to band is axially parallel with lining barrel, and the side of the zone face and lining barrel of metal wave band and the straight band of metal is hung down
Directly, each group metal tape is booked lining barrel lateral surface, forms metal grid on the outside of lining barrel along lining barrel circumferencial direction close-packed arrays
Auxiliary cylinder.Metal grid auxiliary cylinder is fixed by the way of ferrule.
In the above two embodiments, the wave-like of metal wave band can be triangle, can also be polygon or
It is arc-shaped etc..Metal wave band and the straight band of metal fit closely, to ensure burning surface homogenous combustion.
