Center portion position, or on air heat-accumulating burner top (bottom) or be that (right side) insertion is natural on the left of air heat-accumulating burner
Gas blowout pipe.
Former form, natural gas jet pipe are fully located at high-temperature region, although can improve natural gas jet pipe material or
Natural gas jet pipe is made using resistant to elevated temperatures nonmetallic materials, but it is natural gas tube easily scaling loss to actually use situation, is needed regular
Change, influence to produce, cost is high, and this form is the sleeve type structure of air parcel combustion gas, combustion gas by center steel pipe
Spray, combustion air sprays into burner hearth by the sleeve pipe in periphery, and the two burns on burner hearth inner edge mixing side, forms cylinder or loudspeaker
The revolving body flame of shape, flame inside are the reducing atmospheres based on fuel, and outside is steamed with air, carbon dioxide, water
Oxidizing atmosphere based on the combustion products such as gas.On the one hand, blank is surrounded by the oxidizing atmosphere all the time in heating process, causes
Make blank oxidization burning loss serious；On the other hand, degree of sprawling is shorter in the horizontal direction for this revolving body flame, causes high-temperature region collection

Thermal effect, area of localized hyperthermia is also easily formed, and the presence in area of localized hyperthermia, the generation to thermal NO provide just
Sharp condition, cause the amount of nitrogen oxides in combustion product higher, easily cause environmental pollution.
Latter two form, although natural gas jet pipe, not in high-temperature region, natural gas and high temperature combustion air are by each
From spout enter stove in after just while mixing while dispersed combustion, due to the volume ratio of natural gas and high temperature air differ huge, work
Volume ratio about 1 under the conditions of condition:50, easily cause natural gas to mix bad, incomplete combustion with combustion air, over-emitting black exhaust occur and show
As fuel consumption is high, and unburnt natural gas is inhaled into air heat storage tank in commutation process, secondary in heat storage tank
, there is potential safety hazard in burning, and cause heat storage to damage, and influence normally to produce, and production cost is high.
Above no matter which kind of form, during reversing combustion, natural gas jet pipe is under the hyperthermia radiation of furnace gas, spout position
Put easily and knot carbon coking phenomenon occur, ultimately cause the blocking of natural gas jet pipe scaling loss, influence the using effect of burner.

Fig. 5 is the local scheme of installation of the present invention, and heat-accumulating burner may be mounted above heated object --- as " on
Burner ", the multithread stock spout of combustion air are pressed close on heated object with natural gas multithread stock spout in arrangement, gas flow up and down
Surface, it is secondary, away from blank, natural gas premixes and carries out imperfect combustion combustion air with First air half three times, imperfect combustion production
Thing is sprayed into burner hearth at a high speed by mixed gas spout, and volume inhales surrounding furnace gas, increases the volume of combustion product, reduces burning fire
The temperature of flame central area, suppress thermal NO x generation, and the volume of unburnt product gradually increases, by
It is secondary with it is secondary, combustion air is mixed three times, and whole combustion process is completed in burner hearth, realize natural gas and combustion air in stove
It is sufficiently mixed under high temperature disperse formula state, completely burned, temperature field in furnace is uniform.Because combustion-supporting wind snout is all the time away from heated
Part, the flame front for pressing close to blank upper surface are weak reducing atmosphere, can effectively reduce the oxidization burning loss of steel billet, make blank heating matter
Amount is greatly improved.Conversely, heat-accumulating burner may be mounted at below heated object --- as " lower burner ", combustion air
Multithread stock spout and natural gas multithread stock spout are in lower upper arrangement, and gas flow presses close to heated object lower surface, secondary, three times
For combustion air away from blank, the flame front for pressing close to blank lower surface is weak reducing atmosphere, can effectively reduce the oxidization burning loss of steel billet,
Blank heating quality is set to be greatly improved.
A kind of multistage combustion energy-conserving and environment-protective burner of the present embodiment, combustion air can be preheated to 1000 DEG C or so, in fact
Existing waste heat high efficiente callback, reduces fuel consumption, gives full play to the advantage of air staged combustion technology, using combustion with meagre oxygen mechanism,
Ensure that natural gas is sufficiently mixed with air, burnt completely, burner flame face is in reducing atmosphere, effectively inhibits NOx to generate, greatly
The big discharge capacity for reducing the pollutants such as nitrogen oxides.The mixed effect that efficiently solves conventional natural gas single regenerative burner is poor,
Incomplete combustion, fuel consumption are high, flame heating quality is poor, oxidization burning loss is serious, the easy carbon distribution coking of natural gas jet pipe, burning are produced
The pollutant load such as nitrogen oxides is higher in thing waits technical barrier.
Schematically the present invention and embodiments thereof are described above, this describes no restricted, institute in accompanying drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So if common skill of this area
Art personnel are enlightened by it, without departing from the spirit of the invention, without designing and the technical scheme for creativeness
Similar frame mode and embodiment, protection scope of the present invention all should be belonged to.
