Description
Technical field
The utility model belongs to combustion in coal chemical industry equipment technical field, and in particular to a kind of integrated Water-coal-slurry nozzle and
Ignition method.
Background technique
Coal water slurry process burner is the gasification furnace for manufacturing the chemical products such as chemical fertilizer, methanol using coal as raw material.Water coal
Sizing process burner is one of technology the most key in coal water slurry gasification technology, it directly determines the efficiency and stabilization of technique
Property.
Typical coal water slurry process burner be designed to it is coaxial it is interior, in, outer three circles or annular, wherein inside and outside spout is
Oxygen channel, centre are water-coal-slurry channel.Water-coal-slurry and oxygen are sprayed into gasification furnace with high-speed jet, and medium is in gasification furnace
It hits, atomization, burning, and carries out complicated chemical reaction under high temperature, condition of high voltage, ultimately produce effective chemical analysis,
The structure process burner is generally only used for hot wall furnace, currently, all kinds of coal water slurry process burners are at home using for many years, technique is burnt
There are mainly three types of the damage modes of mouth: cooling water coil damage；Heat, chemistry, stress make outer damage of head；Middle spray head physics mill
Erosion.
1. cooling water coil damages
The effect of cooling water coil is to protect burner (body part in hot process gases), outside cooling water coil
Portion's bad environments.Damage mode mainly has following three kinds.
(1) cooling water coil and outer spray head weld thermal stress damage.
(2) cooling water coil during the bending process, bends deflection and Reducing thickness that speed guarantees tubing, and then influence disk
Manage integral strength after molding and rigidity.
(3) in normal course of operation, slag caused by gas backstreaming, which splashes, damages coil pipe.
2. the influence of heat, chemistry, the external spray head of stress
There is diameter radiotropism crackle and irregular cracking in outer spray head end face.After burner operates normally a period of time, along
The edge in outer spray head aperture will appear intensive diameter radiotropism crackle and irregular cracking.
For crackle Producing reason, it is that one extremely complex and composite factor influences as a result, it influences principal element
There is the following aspects.
(1) thermal shock effect: metal material long-term work under such hot conditions, and by high speed coal slurry, oxygen and
The process gas of reflux washes away
(2) chemical affect: high-temperature sulfidation attack.
(3) stress influence: the source of diameter radiotropism crackle is the aperture of outer spray head, this is answering after part machinery is processed
Power concentrate position, under the high temperature conditions, stress release be to form the root of radioactivity crackle, and outer spray head damage it is main
Factor.
The physical abrasion of spray head in 3.
Physical abrasion is the deadly defect of coal water slurry process burner, and influences that gasification furnace is continuous, core of stable operation
One of factor.In order to reach good atomizing effect, flow velocity must reach certain value.Due to containing a large amount of coal dust in mixture
Solid particle causes middle nozzle cavity to wear.Flow velocity can not be too big, and the axial velocity component of too big then mixture is big, flame
Will be elongated, influence residence time and the efficiency of carbon con version of partial material.
For the antiwear property of nozzle cavity in increasing, it is currently the only feasible for selecting the good material of abrasion resistance
Method, while being also contemplated that the antioxygenic property of material.

7 pyramidal structure with one heart and forms outer epoxy that spacing is 14mm into oxygen channel, and outer epoxy is into oxygen channel and outer epoxy into oxygen chamber
Body is connected, and the size of this design value is associated with the flow and temperature fields distribution in exit velocity and entire gasification furnace, out
Mouthful flow velocity more small―gap suture is bigger, and exit velocity gets over that wide arc gap is smaller, according to different oxygen flows, controls exit velocity in 90-
When between 150m/s, which is 8~20mm, and cool water mixture burning effect is best.

Necking form, it is therefore an objective to central oxygen be accelerated, while there is certain retraction in its end face relative to the head end face ring cowling 22-4
Amount forms the premixed chamber of a water-coal-slurry and central oxygen in this way, and the exit design of water-coal-slurry spray head 22-1 is at gradual change necking shape
Formula makes the water-coal-slurry into premixed chamber have certain speed, and the taper of water-coal-slurry spray head 22-1 is bigger, it is therefore an objective to provide more
Hyperoxia gas velocity can form tiny droplet by the oxygen stream " breaing up " of high speed after so that water-coal-slurry mixture is sprayed burner, into
The good atomization of row, to reach good gasification result in gasification furnace, the center of the utility model into oxygen, water-coal-slurry still
Outer epoxy all needs to meet the traffic requirement of respective medium into the circulation area of oxygen, in the case where supply pressure allows, strives
Reach good mixing and atomizing effect, therefore, the ratio of center into oxygen has certain limitation, generally the 10% of total oxygen demand~
20%, remaining is used as outer epoxy into oxygen.Center oxygen feeding amount cannot be too small, and the dilution to coal slurry is not so not achieved and accelerates to make
With.Center oxygen feeding amount can not be too big, on the one hand, oxygen feeding amount, which crosses conference, increases the mixture velocity of premixed chamber too much, makes
At center into the increased wear in the exit oxygen spray head 22-6, the continuous use service life of burner is reduced；On the other hand, center oxygen feeding amount
When increase, necessarily increase the axial velocity component of burner outlet material, radial velocity component reduces, as a result, making entirely to burn
The flame of mouth outlet becomes elongated, can not match with the inner profile of gasification furnace, larger-diameter pulverized coal particle is caused to gasify
Residing time in furnace shortens, and the phosphorus content in clinker increases, and gasification efficiency is caused to reduce.
