Description
Technical field
The present invention relates to a kind of burner, specifically referring to one can be with natural gas, coke-stove gas, producer coal
Gas is the industrial kiln high-power heat exchange type burner of fuel medium.
Background technology
At present, the burner of self-preheating type structure has obtained widely in terms of Industrial Stoves Burner Technology
Application, the preheating of its combustion air is typically all and uses the method increasing separate exchangers to realize.Although should be certainly
The burner of the pre-heated structure of body has a preferable using effect, but it yet suffers from following defect:
One, owing to adds additional separate exchangers on the burner of self-preheating type structure, therefore leads
Having caused whole equipment volume bigger than normal, it installs extremely inconvenience.
Its two, due to self-preheating type structure burner all be use a heat exchange method realize, because of
This its heat exchange power is typically all less than 1500KW, just can only be fired by increase on some big load industrial furnace
The method of burner quantity solves, and not only investment cost is big, and heat transfer effect is poor.
Its three, due to burner wind dish and combustor many employings metal structure of self-preheating type structure burner
Making, therefore its service life is shorter.
In sum, the burner of current self-preheating type structure exists that volume is bigger than normal, install inconvenient, merit
The defect such as rate is less, heat transfer effect is poor and service life is shorter.
Summary of the invention
The purpose of the present invention is just that the volume existing for burner overcoming current self-preheating type structure is inclined
Greatly, the defects such as inconvenient, power is less, heat transfer effect is poor and service life is shorter are installed, it is provided that one
Plant industrial kiln high-power heat exchange type burner.
The purpose of the present invention is achieved through the following technical solutions: a kind of industrial kiln high-power heat exchange type burning
Device, mainly by having the heat exchanger of air flow channel and flue gas flow channel, arrange on heat exchangers and with its air stream

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention do not limit
In this.
Embodiment
As it is shown in figure 1, high-power heat exchange type burner mainly includes heat exchanger 1 described in the present embodiment, it is arranged on
Air inlet duct 4 on heat exchanger 1, the combustor 3 being connected with heat exchanger 1 and air inlet duct 4, if
Put at the blender 2 within combustor 3, the injector 5 being connected with air inlet duct 4, and with mix
Main rifle 6 that device 2 is connected and burning torch 7.
Wherein, heat exchanger 1 is the core heat exchanger components of the present embodiment, and its concrete structure is as shown in Figure 2.I.e.
The coaxial rings crack structure of generally more than 3 layers of this heat exchanger 1, it mainly by exchange cylinder 11, is enclosed within exchange
Inner fin cylinder 12 outside cylinder 11, is enclosed within the outer fin cylinder 13 outside inner fin cylinder 12, and set is outside
Shell 14 outside fin cylinder 13 forms.Above-mentioned exchange cylinder 11, inner fin cylinder 12, outer fin cylinder 13
And the central axis of shell 14 is respectively positioned on same straight line, in addition at inner fin cylinder 12 and exchange cylinder 11
Between be formed with ground floor circumferential weld 113, be formed with second layer ring outside between fin cylinder 13 and inner fin cylinder 12
Seam 112, be formed between shell 14 and outer fin cylinder 13 respectively with ground floor circumferential weld 113 and combustor 3
The third layer circumferential weld 111 being connected.Therefore, said structure is just referred to as " coaxial rings crack structure ".
Owing to ground floor circumferential weld 113 is connected with combustor 3 after third layer circumferential weld 111, during connection,
Its needs are connected with air inlet duct 4, therefore institute between ground floor circumferential weld 113 and third layer circumferential weld 111
The connection circumferential weld formed just is air flow channel.Second layer circumferential weld 112 is flue gas flow channel, and it is direct and outside
Combustion flue is connected, to guarantee that the high temperature combustion flue flue gas by producing in combustion flue can pass through second layer circumferential weld 112
Defeated.
Air inlet duct 4, mainly under the effect of combustion fan, carries to the air flow channel of heat exchanger 1 and helps
Combustion air.As shown in Figure 3,4, i.e. it is by inner sleeve 41, is enclosed within inner sleeve for the structure of this air inlet duct 4
Outside 41 and the trocar sheath 42 of formed circumferential weld, the deflector 43 arranged along inner wall of circumferential seam helically line,
And the fin 44 being arranged on inner sleeve 41 inside forms.Since Ru Ci, the ring of this air inlet duct 4
Seam has become one around the spiral circumferential weld of inner sleeve 41.During connection, the circumferential weld of this air inlet duct 4 is wanted
It is connected with the ground floor circumferential weld 113 of burner 1, to guarantee that combustion air can enter after flowing in the shape of a spiral
To ground floor circumferential weld 113, i.e. enter into air flow channel.
Meanwhile, the internal cavities of inner sleeve 41 to be connected with the inside of combustor 3, to guarantee through combustor
High-temperature furnace gas after 3 abundant burnings is discharged by injector 5 after its internal cavities again.
For guaranteeing that high-temperature flue gas can fully carry out heat exchange, the wing set by inner sleeve 41 inside with combustion air
Sheet 44 can use two ways to realize.One is, every fin 44 is an entirety, and it is uniform
The sidewall being distributed in inner sleeve 41 on；It two is that it is a set of for arranging quantity in inner sleeve 41 inwall front end
Above front end fin, arranging quantity equally in inner sleeve 41 rear inner wall is more than a set of and quantity is equal
Rear end fin, and front end fin and rear end fin be cross arrangement along the central axis of inner sleeve 41.This reality
Executing example preferentially uses the second way to realize.
In order to overcome shorter defect in conventional burners service life, the combustor 3 described in the present embodiment is served as reasons
Burner block assembles the cylinder cavity body of formation.This burner block is then by heat resisting pipe skeleton, and is cast in this
The refractory material of heat resisting pipe skeleton outer surface is prepared from.
Blender 2 is then arranged at the inside of combustor 3, is i.e. positioned at cylinder cavity body portion.Defeated for combustion gas
The one end of the main rifle 6 sent is positioned at the inside of heat exchanger 1, and is connected with blender 2, its other end then position
In the outside of heat exchanger 1, enter for outside combustion gas and realize ignition function.In like manner, burning torch 7
One end is connected with blender 2, and the other end is then positioned at the outside of heat exchanger 1 and for lighting a fire.And this igniting
Rifle 7 is then the igniter for starting main rifle 6.
During operation, burning torch 7 first starts, in order to start main rifle 6.Combustion fan starts and air feed enters to air
Mouth pipe 4.Now, first the combustion air entered from air inlet duct 4 fills with inside combustor 3
The high-temperature flue gas carried after divided combustion and through inner sleeve 41 carries out primary heat exchange；Then, first is carried out
Combustion air after secondary heat exchange again with from combustion flue and in heat exchanger 1 high temperature combustion flue flue gas flow channel conveying
Combustion flue flue gas carries out second heat exchange；Finally carry out the ability of the combustion air after second heat exchange and blended device 2
The combustion gas of input is burnt in combustor 3, and discharges under the effect of injector 5.
As it has been described above, the present invention just can well be realized.
