Abstract
The utility model relates to a nozzle device of premixed combustion of pure oxygen and fuel oil or fuel gas. The nozzle device comprises a fuel oil or fuel gas burner (1), a compressed oxygen swirling flow spout (2), a ceramic ring (3), a nozzle housing (4) and a premixed combustion nozzle outlet (5) from inside to outside successively. The centers of the parts are located on the same axis. The nozzle device employs premixing of the pure oxygen and the fuel oil or fuel gas and enables the fuel oil atomized through pressure to be further atomized through impact or enables the fuel gas to be further contacted with the oxygen through impact by fully employing the characteristics of high speed of flow of compressed oxygen at the spout, thereby realizing full premixing of the pure oxygen and the fuel gas or atomized fuel oil and strengthening combustion of the fuel gas or fuel oil and the pure oxygen.
Description
Technical field
The present invention relates to a kind of fuel oil or combustion gas and fully mix with pure oxygen, and can clean-burning a kind of burning nozzle structure.
Background technology
Fuel oil or the fuel gas buring technology generally used at present are to pass into air, and therefore air distribution combustion, exists following shortcoming:
Summary of the invention
Above problem for existing fuel oil or the existence of fuel gas buring technology, the object of the present invention is to provide fuel oil or combustion gas burn-off rate high, flame rigidity is strong, central temperature is high, momentum is large, flame propagation speed, little, the convenient for installation and maintenance efficiently fuel oil of equipment volume or gas combustion apparatus.
Because the particularity of pure oxygen and fuel oil premixed combustion, its burning shower nozzle just need possess corresponding characteristics: 1, premix should be abundant; 2, the above extreme high temperature of anti-2000 degree; 3, be convenient to dismounting, maintenance; 4, easily manufactured, cost is low.
For above requirement, the object of the present invention is to provide a kind of safety, reliable, the burning shower nozzle of practical a kind of pure oxygen, fuel oil or gas premixing burning.
For reaching above purpose, solution of the present invention is:
The device of a kind of pure oxygen, fuel oil or gas premixing burning shower nozzle, it is characterized in that, this shower nozzle is followed successively by from the inside to the outside: fuel oil or gas nozzle (1), compressed oxygen eddy flow spout (2), ceramic ring (3), nozzle housing (4), premixed combustion shower nozzle outlet (5), and with the center of upper member all on same axial line.
Further, described fuel oil or gas nozzle (1) are apart from premixed combustion shower nozzle outlet (5) 40mm ~ 60mm.
Further, described fuel oil or gas nozzle (1) Range compress oxygen eddy flow spout (2) outlet 5mm ~ 15mm.
Further, described compressed oxygen eddy flow spout (2) places outside fuel oil or the gas nozzle (1), and both centers are all on same axial line, and employing is threaded, and compressed oxygen eddy flow spout (2) is apart from shower nozzle outlet 5mm ~ 15mm.
Further, described compressed oxygen eddy flow spout (2) angle is 40 degree ~ 60 degree, and eddy flow direction and fuel oil or combustion gas atomizing afterwards to form the eddy flow direction consistent.
Further, ceramic ring (3) is positioned at nozzle housing (4) ring wall, makes nozzle housing (4) have high-temperature stability.
Principle of the present invention and characteristics are: change air air distribution fuel oil or the fuel gas buring method generally used traditionally, adopt the burning of pure oxygen and fuel oil or gas premixing, and take full advantage of that nozzle compressed oxygen air-flow characteristics are at a high speed further clashed into the fuel oil of pressure atomization against atomizing or contact is further clashed in combustion gas, thereby make combustion gas or atomized fuel and the abundant premix of pure sun, strengthen response area; Meanwhile, the oxygen of strong eddy flow is consistent with atomized fuel eddy flow direction, has strengthened greatly entrainmenting high-temperature flue gas, make atomized fuel dilatation, heating, within the extremely short time, finish the evaporation gasification of mist of oil, fuel oil, pure oxygen contact area are sharply increased, strengthen fuel oil and pure oxygen burning.
Above principle and characteristics have possessed this burner combustion spout: premix is abundant; High temperature resistant; Be convenient to dismounting, maintenance; The characteristics such as easily manufactured, cost is low are conducive to use at specific environment.
Description of drawings:
Fig. 1 is the utility model apparatus structure schematic diagram.
The specific embodiment:
Below in conjunction with specification and Fig. 1 pure oxygen, oil or gas premix burner are described further.
The device of a kind of pure oxygen, fuel oil or gas premixing burning shower nozzle, this shower nozzle is followed successively by from the inside to the outside: fuel oil or gas nozzle (1), compressed oxygen eddy flow spout (2), ceramic ring (3), nozzle housing (4), premixed combustion shower nozzle outlet (5), and with the center of upper member all on same axial line.
Fuel oil or gas nozzle (1) are apart from premixed combustion shower nozzle outlet (5) 40mm ~ 60mm.Fuel oil or gas nozzle (1) Range compress oxygen eddy flow spout (2) outlet 5mm ~ 15mm.
Compressed oxygen eddy flow spout (2) places outside fuel oil or the gas nozzle (1), and both centers are all on same axial line, and employing is threaded, and compressed oxygen eddy flow spout (2) is apart from shower nozzle outlet 5mm ~ 15mm.
Compressed oxygen eddy flow spout (2) angle is 40 degree ~ 60 degree, and eddy flow direction and fuel oil or combustion gas atomizing afterwards to form the eddy flow direction consistent.
Ceramic ring (3) is positioned at nozzle housing (4) ring wall, makes nozzle housing (4) have high-temperature stability.
The compression fuel oil is formed hollow by fuel oil or gas nozzle (1) by pressure atomization or semi-hollow eddy flow cone mist of oil, again since compressed oxygen stream by having 40 degree ~ 60 degree angles and the compressed oxygen cyclone spout (2) on same axle center to shear the just further contact area of atomized fuel and increase fuel oil and oxygen of cone mist of oil.
Again because the cause of high speed oxygen air-flow, entrainment back simultaneously a large amount of high-temperature flue gas, fuel oil is carried out dilatation, heating, finish the evaporation gasification to fuel spray within the extremely short time, fuel oil, pure oxygen contact area are sharply increased, fully burning in the fuel oil short time discharges heat energy, thereby it is strong to show flame rigidity, the characteristics such as momentum is large, and central temperature is high, and spread speed is fast.
Above enforcement; it only is the general description to this patent; be not that scope to this patent limits; under the prerequisite that does not break away from this patent design spirit; anyone is to various distortion and improvement that the technical scheme of this patent is made, all should fall in the protection domain that claims of this patent determine.
