Description
Technical field
The utility model relates to technical field of burner, the burner that especially a kind of coal gas of high temperature and fuel oil are dual-purpose.
Background technology
Coal Gasification Technology is one of key technology of the solid carbon-containing fuel clean and effective utilizations such as current coal, living beings, petroleum coke, is also the main path that primary energy is converted into clean secondary energy sources.China is a big coal country, is also furtheing investigate always, and obtain very large success in Coal Gasification Technology.
Coal Gasification Technology had obtained very big breakthrough preparing aspect industrial combustion gas in recent years, particularly to prepare the technology that industrial combustion gas applies to aggregate heating system constantly ripe for fine coal atmospheric air gasification technology, because its clean environment firendly, manipulation are convenient and the advantage such as fuel saving cost greatly, just progressively replace traditional aggregate heating technique using fuel oil as fuel.For example operate in the fine coal atmospheric air gasification system of aggregate heating in bituminous mixing plant, just can save fuel cost over half, there are sizable market prospects.
In fine coal air gasification process, the gas temperature of gasification furnace outlet is higher, is generally 900~1200 ℃.For the maximization of energy, use, make full use of the sensible heat in coal gas of high temperature, directly using is most economical way.Because coal gas of high temperature has the features such as temperature is high, volume flow is large, the industrial furnace burner technology that directly uses high-temperature fuel gas is current still immature.Meanwhile, in order to guarantee to stablize lasting production, such gas burner is also wanted to use fuel oil simultaneously, to still can normally produce when coal gasifier fault or maintenance.
Therefore,, under the background developing rapidly in Coal Gasification Technology, both burning coal gas of high temperature of exploitation one, can be used again the dual burner of fuel oil to be necessary very much.
Utility model content
The deficiency that the utility model exists for prior art, provides a kind of coal gas of high temperature and fuel oil dual-purpose burner, makes its burning respectively that is applicable to two kinds of fuel such as coal gas of high temperature, fuel oil or the operating mode of two kinds of fuel arbitrary proportions mixed combustion.
For this reason, the utility model adopts following technical scheme: the burner that a kind of coal gas of high temperature and fuel oil are dual-purpose, comprise gas passage and the multiple combustion air nozzles that are arranged on gas passage front end, it is characterized in that, described multiple combustion air nozzles form at least one row, the multiple combustion air nozzles that are arranged in same row are circumferentially evenly arranged along gas passage, and the angle β that the axis of combustion air nozzle becomes with gas passage cross section longitudinal axis is 0~15 °;
The center of described gas passage is provided with air channel, center, and Gai center is provided with oil gun and igniter in air channel, and it circumferentially evenly arranges multiple swirl vanes air channel, center front end edge, and the angle γ of the axis of described swirl vane and air channel, center center line is 25~70 °.
Described oil gun is used for the various fuel oils that spray burning is used, and igniter is used for the fuel oil starting ignition after atomization to use.The composition of described coal gas of high temperature comprises one or several the mixture such as carbon monoxide, hydrogen, methane, hydrocarbon compound, semicoke.
Workflow during burner operation is as follows: when using fuel oil, fuel oil sprays through oil gun atomization, air channel, Yi Cifengjing center, swirl vane eddy flow spray and drive the fuel oil initial burning after atomization, and Secondary Air sprays into through combustion air nozzle, drive fuel oil fully to burn; When using coal gas of high temperature, coal gas of high temperature enters from gas passage, and the air entering with combustion air nozzle or air channel, center mixes and burns; When two kinds of fuel burn simultaneously, it is the stack of above-mentioned two kinds of flow processs.
As preferably, at least four of the numbers in row's combustion air nozzle form a circle of contact by the inner of the multiple combustion air nozzles in same row in burner, and its eddy flow direction is identical with the eddy flow direction of swirl vane.
As preferably, the angle β that the axis of described combustion air nozzle becomes with gas passage cross section longitudinal axis is 5~10 °.
As preferably, the angle γ of the axis of described swirl vane and air channel, center center line is 35~50 °.
The beneficial effect the utlity model has: the equipment such as gas passage, combustion air nozzle, air channel, center, oil gun and igniter by reasonable Arrangement burner, make the utility model burner be applicable to the burning respectively of coal gas of high temperature and fuel oil or the operating mode of two kinds of fuel arbitrary proportions mixed combustion, guaranteed to start rapidly oil inflame when the short confession of high-temperature fuel gas, guaranteed the continuity of kiln work.The no matter mixture of combustion high temperature coal gas, coal gas of high temperature and semicoke, fuel oil, fuel oil inferior, its efficiency of combustion is all high more than 5~10% than normal burner, facts have proved, and while using this burner, flame is bright, full, without black smoke, burns very abundant.
