Multichannel combination burner 1 for coal slurry gasifier 100 according to embodiments of the present invention is described below with reference to Fig. 1.
The Multichannel combination burner 1 for coal slurry gasifier 100 of reference picture 1, according to a first aspect of the present invention embodiment,
Including burner body and fire rod 5.
Specifically, one end (for example, referring to lower end of burner body in Fig. 1) of burner body is provided with and is suitable to and water-coal-slurry
The first oxygen connected respectively with burner mouthful 11 is defined in the burner mouthful 11 that the furnace chamber 10 of gasification furnace 100 is connected, burner body
Gas passage 12, the second oxygen channel 15, fuel gas passageway 21 and coal slurry channel 31.Wherein, the first oxygen channel 12,
Two oxygen channels 15 can be passed through oxygen, and fuel gas passageway 21 can be passed through fuel gas, and coal slurry channel 31 can be passed through coal
Slurry.The outlet of coal slurry channel 31 outwards exceeds the outlet of the first oxygen channel 12 and the outlet of fuel gas passageway 21, in order to
Coal slurry in coal slurry channel 31 is flowed into the furnace chamber 10 of coal slurry gasifier 100 from exit.
Fire rod 5 is movably located in burner body, and the firing tip 51 of fire rod 5 is in point in coal slurry gasifier 100
During the fiery stage in fuel gas passageway 21 and between the outlet of the first oxygen channel 12 and the outlet of coal slurry channel 31,
And stretched into after the completion of the igniting of coal slurry gasifier 100 in the first oxygen channel 12.Thus, in coal slurry gasifier 100
During in ignition phase, the firing tip 51 of fire rod 5 is located at going out in fuel gas passageway 21 and positioned at the first oxygen channel 12
Between mouth and the outlet of coal slurry channel 31, now oxygen is entered by the first oxygen channel 12 and the second oxygen channel 15 respectively
Burner mouthful 11, fuel gas enters burner mouthful 11 by fuel gas passageway 21, and fire rod 5 is lighted a fire, and fuel gas is in burner
Burnt at mouth 11.Oxygen, can by entering burner mouthful 11 by the first oxygen channel 12 and the second oxygen channel 15 respectively
So that fuel gas is sufficiently mixed with oxygen, and the swept area of combustion flame can be increased.
After the completion of coal slurry gasifier 100 is lighted a fire, fire rod 5 is stretched into the first oxygen channel 12, thus it can be prevented that igniting
Rod 5 is burned, and extends the service life of fire rod 5.Then, stove can be adjusted by increasing the flow of fuel gas and oxygen
Intrinsic thermic load, it is possible thereby to be preheated to coal slurry gasification furnace.Coal slurry gasification furnace preheat complete when, i.e. furnace chamber 10
When interior temperature reaches feed temperature, now coal slurry is entered by coal slurry channel 31 in the furnace chamber 10 of coal slurry gasification furnace, and is stopped
The only conveying of fuel gas, progressively increase amount of oxygen and coal slurry amount until coal slurry gasification furnace at full capacity.
Thus, during coal slurry gasifier 100 is run, Multichannel combination burner 1 need not switch burner just can be real
Now light a fire, heat up, feed intake integration work, thus it can be prevented that coal slurry gasifier 100 in the process of running because switching is burnt
Mouth and the furnace flame that occurs spray, too low in-furnace temperature and the problems such as leakage, thereby may be ensured that coal slurry gasifier 100
Reliably continuously run, and the security of coal slurry gasifier 100 can be improved.
The Multichannel combination burner 1 for coal slurry gasifier 100 according to embodiments of the present invention, by by multiple passage groups
Close, can make coal slurry gasifier 100 need not switch burner can just realize igniting, heat up, feed intake integration work, by
This can prevent the furnace flame that coal slurry gasifier 100 occurs because switching burner in the process of running from spraying, in-furnace temperature
The problems such as too low and leakage, so as to improve the reliability of operation of coal slurry gasifier 100, and in coal slurry gasifier
Fire rod 5 can be stretched into the first oxygen channel 12 after the completion of 100 igniting, it is possible thereby to extend the service life of fire rod 5,
Coal slurry gasifier 100 need to carry out once mounting operation simultaneously, and without changing burner, more convenient operation can be improved
Production efficiency.
In some embodiments of the invention, reference picture 1, Multichannel combination burner 1 also includes at least one flame detector 7,
It can also be multiple that i.e. flame detector 7, which can be one,.Flame detector 7 is adapted to extend into coal slurry gasifier 100,
To detect the ignition conditions in coal slurry gasifier 100.Thus, can according to the ignition conditions in coal slurry gasifier 100
Suitably to adjust the amount of oxygen, the amount of fuel gas and its ratio, so as to improve the pre- thermal efficiency.
It is understood that when flame detector 7 is set to multiple (for example, two), multiple flame detectors 7 can
With being arranged circumferentially along coal slurry gasifier 100, so as to be conducive to observing coal water slurry gasification with direction from different angles
Flame combustion situation in stove 100.
In some embodiments of the invention, reference picture 1, Multichannel combination burner 1 also includes executing agency 6, executing agency
6 are connected with fire rod 5 is moved with drive ignition rod 5.For example, in the example of fig. 1, being opened in coal slurry gasifier 100
When beginning to run, the drive ignition rod 5 of executing agency 6 is moved down, so that the firing tip 51 of fire rod 5 is located at fuel gas passageway
In 21 and between the outlet of the first oxygen channel 12 and the outlet of coal slurry channel 31, now fire rod 5 can be carried out a little
Firer makees.After the completion of the igniting of fire rod 5, fire rod 5 is stopped, and now the drive ignition rod 5 of executing agency 6 is upward
Mobile, the firing tip 51 of fire rod 5 is retracted in the first oxygen channel 12.Thus, it is possible to prevent fire rod 5 to be burned,
Extend the service life of fire rod 5.
In some embodiments of the invention, reference picture 1, burner body includes oxygen inner tube 13, cartridge 22, coal slurry pipe
32 and oxygen outer tube 16.Specifically, the first oxygen channel 12 is defined in oxygen inner tube 13, fire rod 5 is along along oxygen
The axial direction of pipe 13 is movably located in oxygen inner tube 13, to drive firing tip 51 to extend into or out the first oxygen channel 12.
Cartridge 22 is set in the outside of oxygen inner tube 13, and fuel gas passageway 21 is limited between cartridge 22 and oxygen inner tube 13,
Coal slurry pipe 32 is set in the outside of cartridge 22, is limited between coal slurry pipe 32 and cartridge 22 outside coal slurry channel 31, oxygen
Pipe 16 is set in the outside of coal slurry pipe 32, and the second oxygen channel 15, oxygen are limited between oxygen outer tube 16 and coal slurry pipe 32
One end of outer tube 16 is provided with burner mouthful 11.
Thus, it is possible to make the simple in construction, compact of Multichannel combination burner 1, and coal slurry gasifier 100 is contributed to exist
Warm-up phase oxygen and fuel gas are sufficiently mixed so that fuel gas fully burns, and the efficiency of heating surface are improved, while also contributing to
Coal slurry and oxygen are sufficiently mixed when being fed intake, and improve the gasification efficiency of coal slurry.Alternatively, fire rod 5, oxygen inner tube
