Description
Technical field
This utility model relates to a kind of burner, particularly to a kind of new type high temperature rotational flow air burner.
Background technology
HTAC has energy-efficient and low pollution emission dual superiority in commercial Application, is subject to
Scientific circles and the extensive concern of industrial quarters, and be successfully applied to iron and steel, metallurgy, machinery, etc. in industrial department, presented swift and violent
The impetus of development, becomes one of the most promising combustion technology.At present, the industrial furnace equipment of China is large number of, its energy
Consumption accounts for the 1/4 of whole nation industry total energy consumption, and most industrial furnace have employed traditional combustion system, causes energy consumption too high, heat
Efficiency is low, seriously polluted.Application HTAC can be the relevant industries of China bring the biggest economic benefit with
Environmental benefit, develops and applies this technology tool to be of great significance.At present, the high temperature air combustion applied in engineering
The burner structure major part burning industrial furnace is all that high-temperature preheated air and gaseous fuel spray into stove at a high speed in the way of direct projection stream
Thorax.
But direct projection stream burner is in use, it has been found that problem once:
1. atomization is not good enough.After straight Gas Jet entrance combustor, the mixability with fuel oil is substantially reduced, and causes
Burning insufficient, efficiency of combustion is substantially reduced.
2. range of circulating flow and degree ratio in the stove that direct projection stream causes are relatively limited, and Comparatively speaking, eddy flow can play preferably
Immixture.In addition, the mode that sprays into of conventional direct projection stream make fuel oil in high temperature environments burn produce nitrogen oxidation
The concentration of the pollutant such as thing is greatly increased.
Utility model content
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that a kind of new type high temperature eddy flow is empty
Air burner, by the eddy flow of gas fuel oil is atomized and change supersonic combustor distribution make fuel in combustion chamber oil with
The mixability of preheated air is greatly increased, thus improves efficiency of combustion, reduces the discharge of pollutant.
Its technical scheme is: include air inlet, air inlet pipe, fuel oil burner, oil inlet pipe, smoke chamber exocoel
The outlet of body, regenerative apparatus, air cyclone, gas fume of combustion chamber, combustor, smoke chamber, high-temperature flue gas outlet, described combustor sets
At smoke chamber inner chamber, chamber front end installs fuel nozzle and air cyclone, is distributed outside the outlet of described gas fume of combustion chamber
Having regenerative apparatus, described smoke chamber is column structure, and the top of smoke chamber is provided with high-temperature flue gas outlet.
Above-mentioned combustor is column structure.
The beneficial effects of the utility model are: air swirl technology is had by this utility model with high-temp combustion technology
The high temperature swirl flow combustion being implemented in combination with fuel oil of machine, thus substantially increase the adequacy of burning, reducing nitrogen oxidation
Improve again efficiency of combustion while the pollutant emissions such as thing, and this burner structure is simple, cost of manufacture is low, is readily obtained
Promote the use of on a large scale.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
In upper figure: air inlet 1, air inlet pipe 2, fuel oil burner 3, oil inlet pipe 4, smoke chamber outer chamber 5, regenerative apparatus
6, air cyclone 7, gas fume of combustion chamber outlet 8, combustor 9, smoke chamber 10, high-temperature flue gas outlet 11.
Detailed description of the invention
In conjunction with accompanying drawing 1, the utility model will be further described:
This utility model include air inlet 1, air inlet pipe 2, fuel oil burner 3, oil inlet pipe 4, smoke chamber outer chamber 5,
Regenerative apparatus 6, air cyclone 7, gas fume of combustion chamber outlet 8, combustor 9, smoke chamber 10, high-temperature flue gas outlet 11, described cigarette
Air chamber outer chamber 5 is internal is provided with combustor inner chamber body 9, described combustor 9 front end and fuel nozzle 3 and air cyclone 7 phase
Connecting, regenerative apparatus 6 is distributed outside described gas fume of combustion chamber outlet 8, described smoke chamber 10 is column structure, smoke chamber 10
Upper end is provided with high-temperature flue gas outlet 11.
Wherein, air enters combustor 9 with rotation streaming mode after air inlet pipe 2 enters cyclone 7；Above-mentioned regenerative apparatus 6
It is connected with air inlet pipe 2.
This utility model is that air swirl technology and high-temp combustion technology have been carried out organic combination, utilizes swirling eddy
Atomized fuel oil, utilizes gas energy warm-up fuel, is considerably increasing burning degree, while improve efficiency of combustion, and fall
The low discharge capacity of pollutant.
Its work process: combustion air enters cyclone 7 through air inlet pipe 2 and forms rotational flow air flow field, in jet axis district
Territory creates internal reflux district, reaches to reclaim high-temperature flue gas ability, stablizes the effect of flame.Fuel oil through fuel nozzle 3 with direct projection
The form of stream sprays at a high speed combustor 9, and volume inhales substantial amounts of flue gas in stove, reduces the oxygen concentration in combustion air jet thus has
Help the atmosphere pollutions such as the nitrogen oxides that controlling burns produces.In chamber system, gas fume of combustion chamber outlet 8 is arranged on combustion
Burn near the import of room, thus contribute to the Involving velocity of combustion air and fuel oil.The gas energy that burning produces passes through accumulation of heat
Air in air inlet pipe 2 is preheated by device 6, thus contributes to high-temp combustion.Finally, the flue gas that burning produces passes through flue gas
Exhanst gas outlet 11 above room 10 is discharged.
The above, be only preferred embodiment of the present utility model, and any those of ordinary skill in the art all may profit
By the technical scheme of above-mentioned elaboration this utility model revised or be revised as equal technical scheme.Therefore, foundation
Any simple modification that the technical solution of the utility model is carried out or substitute equivalents, belong to the greatest extent this utility model claimed
Scope.
