Flame directly washes away the problem of workpiece heating.
5, furnace roof flat-flame burner is mounted on heating furnace furnace roof, and required burner can be arranged according to the width of stove
Quantity, therefore it solves the problems, such as that wide type of furnace furnace temperature is uneven.
6, all components of furnace roof flat-flame burner are detachable or replace, this just greatly increases each another component of burner
Utilization rate.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the natural gas radiation flat-flame burner structural schematic diagram provided in the present embodiment；
Fig. 2 is the bottom view of Fig. 1；
Wherein: (1) natural gas adapter tube, (2) combustion air adapter tube and burner shell, (3) air cyclone (4) natural gas
Cyclone, (5) are tubaeform burner block, (6) peep fire and gown part is hung in electric ignition hole, (7) burner.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
The utility model proposes a kind of for the new of the industries industrial furnace such as metallurgy, petrochemical industry, building materials, fire resisting, boiler, machinery
Type burner, i.e. natural gas radiate flat-flame burner, which specifically includes that natural gas adapter tube 1, combustion air adapter tube and burning
Mouth shell 2, air cyclone 3, natural gas swirl device 4, tubaeform burner block 5, peeps fire and electric ignition hole 6, burner hang gown part 7.
Its natural gas is 12-16m/s in velocity in pipes.Its structure is drawing out type.
Burner shell is the circular case structure made of certain thickness steel plate, and being lined with specific gravity is γ=0.8t/m3
Lightening casting insulation material, be welded with the stainless steel anchor that material is 1Cr18Ni9Ti every 50-80mm between lightening casting insulation material
Firmware.It needs to toast by certain temperature curve after the casting of lightening casting insulation material.The all connectors of cabinet are that can roll over imperial formula.
Combustion air enters through air cyclone 3 into burner core part from outer.The aperture of air cyclone 3 is along sky
The circumference of cyclonic current device 3 cuts burner core, swirl strength S=5-9, β=8-12 ° of α=25 ° in the shape of a spiral.Its flow velocity w
=35-50m/s.Its material is Cr25Ni20SiN.
Natural gas is burner core part to be screwed in out of natural gas swirl device 4 and with its direction of rotation of combustion air mixing
It is just on the contrary and identical with air direction of rotation.The aperture of natural gas swirl device 4 be along cyclone 4 surrounding in the shape of a spiral
Cut burner core, swirl strength S=4-6, β=6-10 ° of α=20 °.Its flow velocity w=30-40m/s.Its material is
Cr25Ni20SiN。
Tubaeform burner block 5 is equipped with peephole, burner fire hole, and tubaeform burner block 5 hangs gown on furnace roof, because
This, tubaeform burner block 5 wants pre-buried 4 groups of heat resisting steel stainless steels to hang gown part when being poured.The loudspeaker port radius one of tubaeform burner block 5
As be R=150-250mm.Its material is zirconium mullite refractory material, and castable needs to dry by certain temperature curve after casting
It is roasting.
This natural gas radiates flat-flame burner, and burner integral installation is on the furnace roof of industrial furnace, inside burner, burner
Equipped with ingenious unique structure, before natural gas and air burner are mixed and burned, ingenious unique nozzle structure makes in burner
Air and natural gas all there is radial and axial rotary force, and keep its direction of rotation opposite.Natural gas and combustion air are being burnt
Mouth inner edge rotation side moves forwards, and calculates its suitable swirl strength by precision, using the wall attachment effect of rotational flow gas,
Under the guiding of unique burner block, burner combustion is formed by thermal-flame and just forms the flat flame profile of dish type.In this way, industrial
It is heated workpiece in furnace, not traditional flame ejected with burner directly washes away heating workpiece, and flat flame is straight
The furnace roof for connecing heating furnace kiln, the heating furnace furnace roof heated by flat flame heat workpiece, therefore the heating of workpiece with the method for radiation
Especially uniformly.Due to avoid flame directly wash away workpiece heating, in this way, avoid workpiece heating process generate overheat,
The problems such as burning, decarburization, particularly with heating, some special rolling-mill sections are even more important.
This natural gas radiation flat-flame burner also solve large scale industry stove, the wide type of furnace furnace temperature width direction on
Temperature uniformity problem.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
