Description
Technical field
This utility model is related to a kind of burner, specifically a kind of coil pipe cooled burner for being applied to BGL gasification furnaces.
Background technology
In BGL gasification furnaces, lump coal is entered by the lock hopper at the top of coal charge bed in the gasification furnace of pressurization, in this process
Middle slagging scorification agent and coal add together.When coal is moved in gasification furnace from top to bottom against air-flow upwards, waved by drying, removing
Send out and divide, gasify, finally burning.In the substrate of gasification furnace, the mixture of water vapour and oxygen is sprayed into combustion zone by nozzle, here oxygen
Hyperpyrexia of the temperature higher than 2000 DEG C is discharged with remaining burnt reaction.Such high temperature be enough to make grey fusing, and provide heat with
Support gasification reaction.Liquid lime-ash is first discharged in furnace bottom collecting pit, then enters automatically water cooling plant again.Lime-ash is in water cooling plant
Form a kind of slag shape vitreous solid that is tasteless, can not being percolated.
As there is BGL gasification furnaces coal to change into, synthesis gas efficiency is higher, and disposal ability is high, and steam and oxygen consumption are few,
In product gas, CO2 contents are low and the advantage of slag departure process in the form of not leachable glass-clear solid, therefore
BGL gasification furnaces are widely paid close attention in recent years.But the burner due to being applied on BGL gasification furnaces needs to be inserted into slag

Further, the thickness of the dividing plate is more than or equal to 10mm.
The beneficial effects of the utility model are：
1st, cooling water cavity is arranged by the head in burner body, makes cooling water enter directly into the head of burner body, between having
Connect to cool down to be changed into directly cooling down and effectively avoid in traditional burner as heat conduction causes the feelings of burner head damage not in time
Condition, is that burner head is maintained in certain safe temperature, extends the service life of burner.
2nd, the nozzle in this utility model is using the structure for detachably adjusting, when needing to adjust, by nozzle from chuck
Extract out, after adjusting size, in insertion chuck, firm welding just can be used, convenient, simple and direct.
3rd, pass through dividing plate is arranged in cooling water cavity, and pod apertures are set on dividing plate, and described pod apertures are before tiltedly
Side arranges, so that cooling water forms uniform High Speed Flow Field, the high temperature to head in high-temperature region in water outlet intracavity formation vortex
Area carries out uniform decrease in temperature, so not only increases cooling effect, while also avoiding cooling water rapid evaporation in an environment of high temperature
Become gas, it is unfavorable that burner is caused.

Specific embodiment
As shown in Figures 2 and 3, a kind of coil pipe cooled burner for being applied to BGL gasification furnaces includes burner body 1, the burning
It is provided with for being passed through the centre bore 15 of oxygen and steam gas along the direction of gyroaxis on mouth body 1.The burner body 1
Front end (with the direct of travel of air-flow as front, similarly hereinafter) is provided with cooling water cavity 11, and the front end of the burner body 1 passes through cooling water
Chamber 11 protrudes from the outside of cooling water cavity 11.Dividing plate 12 is provided with described cooling water cavity 11, and described dividing plate 12 will cooling
Water cavity 11 has been divided into intake antrum 13 and water chamber 14, and described water chamber 14 is enclosed in the outside of the intake antrum 13, institute
The intake antrum 13 that states is connected with water inlet pipe 2, and described water chamber 14 is connected with outlet pipe 3.Described water inlet pipe 2 and water outlet
Pipe 3 is wrapped in the outside of the burner body 1, and described water inlet pipe 2 and outlet pipe 3 are arranged in double-spiral structure.
If as shown in figure 4, be provided with dried layer pod apertures 121 in the axial direction on described dividing plate 12, as a kind of concrete
Embodiment, is provided with five layers of pod apertures 121 in the axial direction in the present embodiment.As shown in Figure 6 and Figure 7, leading described in each layer
Discharge orifice 121 is uniform in an axial plane, as shown in fig. 7, the angle i.e. between the pod apertures 121 of adjacent layer is equal, is α.Such as
Shown in Fig. 5, along arrangement in the same direction, (referring in the same direction here is all clockwise or is all counterclockwise each pod apertures 121 in per layer
Arrangement), the main purpose of so design is, by the pod apertures 121 being obliquely installed along diagonally forward, to make cooling water in water chamber 14
Interior formation is vortexed, and so as to form uniform High Speed Flow Field in high-temperature region, carries out uniform decrease in temperature to the high-temperature region of burner head, with suitable
The high intensity of burner, high temperature is answered continuously to run, it is to avoid area of localized hyperthermia occur and cause radiating uneven, localized burn occur.Separately
On the one hand cooling water can also be avoided in head high-temperature region rapid evaporation, becomes gas, make the pressure rise in cooling water cavity 11,
Burner is caused to damage.
Further, if described cooling water cavity 11 is using taper or other angular shapes of tool, in water chamber 14
During interior formation vortex, sharp corner occurs cooling dead angle, i.e., do not have cooling water to enter at this, or do not flow after cooling water is entered
Dynamic, so that the position temperature is raised, effectively cannot cool down, for this purpose, preferably, described cooling water cavity 11 adopts hemisphere
Shape, accordingly, described dividing plate 12 is hemisphere planar, and described dividing plate 12 and described 11 arranged concentric of cooling water cavity.
Further, due to when the thickness of dividing plate 12 is excessively thin, can affect be vortexed formation, it is preferred, therefore, that described every
The thickness of plate 12 is more than 10mm.
Further, due to burner outlet size need specifically calculated according to the loading of burner, therefore when
The loading of burner is accomplished by entirely changing burner when changing, and not only Renewal process is loaded down with trivial details, and needs standby plurality of specifications
Burner, cost also can increase therewith, and in order to overcome this class problem, as shown in Fig. 3, the front end of the centre bore 15 is provided with
The boss of annular is together form between first hole, and the first described hole and centre bore 15, is provided with the first described hole
Nozzle 4, the rear end of the nozzle 4 are resisted against on described annular boss.So when nozzle 4 is installed, directly nozzle 4 is inserted
Dao burner mouth in, the rear end of nozzle 4 is made to be resisted against on the boss of annular, then by the front end of nozzle 4 and 1 firm welding of burner body
?.When needing to change nozzle 4, it is only necessary to polish off the solder joint of 4 front end of nozzle by way of grinding, then pull out spray
Mouth 4 is changed, convenient and swift, it is not necessary to change whole nozzle 4.
