Description
Technical field
The utility model belongs to gasification furnace structure, and in particular to a kind of gasification furnace process burner structure.
Background technique
It is combustion apparatus important in industrial furnace currently, burner is larger in industrial furnace related fields demand, China at present
Burner used in relevant industries generally uses external product, expensive, and service life is short, and operation and maintenance cost are high.
In addition, there is also following obvious disadvantages for existing burner: first is that cooling water cavity is a simple cavity, cooling water flow velocity
Slowly, it is easy vaporization, even so as to cause inhomogeneous cooling, effect is poor.Second is that combustion high temperature area is gathered in existing burner use process
The head of burner body is easy to burn out on the head of burner body.The burning of coke-stove gas and oxygen is violent exothermic combustion, burning
The head that high-temperature region is gathered in burner body shortens the service life of burner.
Utility model content
The purpose of the utility model is to provide a kind of gasification furnace process burner structures.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of gasification furnace process burner structure, including high pressure steam generator and fine coal conveyance conduit, the fine coal conveying
Pipeline is orderly arranged outside each oxidant channel and cooling duct, is provided with annular steam pipeline, ring in the fine coal transfer passage
Shape jet chimney bottom is uniformly distributed towards downward steam jet, and annular steam pipeline top is sent out by first pipe and high steam
Raw device connection；Steam (vapor) outlet is arranged in the top of the cooling duct, and bottom is provided with cooling water outlet, is arranged in cooling duct high
Cooling water pressure channel, the top in the high-pressure cooling water channel are arranged high-pressure cooling water import, and high-pressure cooling water channel is towards powder
Coal conveyance conduit side is evenly arranged with high-pressure cooling water nozzle.
The cooling water outlet connects cooling water storage tank by second pipe, and cooling water storage tank passes through booster pump and high pressure water
Import connection.
Heat exchanger is set on the second pipe.
The steam (vapor) outlet connects third pipeline, and third pipeline is connected to by threeway with first pipe.
The outlet at bottom end of fine coal conveyance conduit includes two sections, and upper section is in back taper, and lower part is cylindrical in shape；Oxidant is logical
The outlet at bottom in road is back taper.
Compared with prior art, the utility model has the advantage that
The high-pressure cooling water nozzle that the utility model uses directly sprays oxidant channel, can enhance heat transfer and disturb
Dynamic, very big augmentation of heat transfer effect prolongs the service life so that protection burner temperature is excessively high well；
It is on the one hand used as the carrier gas of fine coal using steam, the density of fine coal is on the other hand diluted, with fine coal transfer passage
The outlet end of lower section cooperates, and accelerates the flow velocity of fine coal, extends the spray distance of fine coal, so that it is poly- further to solve combustion high temperature area
Collect the problem for causing burner temperature excessively high on the head of burner body；
The high-temperature water flowed out out of cooling duct is recycled by sending after heat exchange to cooling water storage tank, while by
The steam that cooling duct generates is utilized after sending to jet chimney, and whole process heat maximizes the use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of annular jet chimney in the utility model.
Specific embodiment
A kind of gasification furnace process burner structure as depicted in figs. 1 and 2, including high pressure steam generator 1 and fine coal conveying
Pipeline 2, the fine coal conveyance conduit 2 are orderly arranged outside each oxidant channel 3 and cooling duct 4, in the fine coal transfer passage 2
It is provided with annular steam pipeline 21,21 bottom of annular steam pipeline is uniformly distributed towards downward steam jet 211, annular steam pipeline
21 tops are connect by first pipe 5 with high pressure steam generator 1；Steam (vapor) outlet 41, bottom is arranged in the top of the cooling duct 4
Portion is provided with cooling water outlet 42, and high-pressure cooling water channel 43, the top in the high-pressure cooling water channel 43 is arranged in cooling duct 4
High-pressure cooling water import 44 is arranged in portion, and it is cold that high-pressure cooling water channel 43 towards 2 side of fine coal conveyance conduit is evenly arranged with high pressure
But (operating) water nozzle 45.The cooling water outlet 42 connects cooling water storage tank 7 by second pipe 6, and cooling water storage tank 7 passes through booster pump
8 connect with high-pressure cooling water import 44.Heat exchanger 8 is set on the second pipe 6.
The steam (vapor) outlet 41 connects third pipeline 9, and third pipeline 9 is connected to by threeway with first pipe 5.Fine coal conveying
The outlet at bottom end of pipeline 2 includes two sections, and upper section 22 is in back taper, and lower section 23 is cylindrical in shape；The bottom of oxidant channel 3 goes out
Mouth is back taper.
The working process of the utility model is as follows: steam generator 1 generates steam, into fine coal conveyance conduit 2, carries in steam
Under body effect, the density of fine coal is diluted, and cooperate with the outlet end of the lower section of fine coal conveyance conduit 2, the flow velocity of fine coal is accelerated, powder
The spray distance of coal extends, and causes burner temperature is excessively high to ask to solve combustion high temperature area and be gathered in the head of burner body
Topic；Directly oxidant channel is sprayed using the high-pressure cooling water nozzle 45 in the present apparatus, heat transfer disturbance can be enhanced, greatly
Augmentation of heat transfer effect prolongs the service life so that it is excessively high to further decrease burner temperature；The height flowed out out of cooling duct 4
Warm water is recycled by sending after heat exchange to cooling water storage tank 7, while being sent by the steam that cooling duct 4 generates to steam
It is utilized after pipeline, whole process heat maximizes the use.
