Abstract
The utility model provides a gas burner which comprises an inner tube, an outer tube and a lining, wherein the spraying outlet of the burner is provided with a fire resistant material body with an inner hole, and the inner hole of the fire resistant material body is communicated with the inner tube of the burner. When the gas burner is used, the flame of the burner is only contacted with the fire resistant material body, and does not contact with the inner tube of the burner, thus playing a role in protecting the burner. The gas burner can be installed vertically or horizontally or in a certain inclined angle, as the flame only contacts with the fire resistant material body, the service life of the burner is prolonged by 12 to 13 months.
Description
Technical field
The utility model relates to a kind of fuel burner nozzle.
Background technology
The tradition fuel burner nozzle is made up of inside and outside two-layer seamless steel pipe, and middle the employing watered the material feeding filling as inner lining material.The tradition fuel burner nozzle in use, burner outlet 2-4cm place inner layer steel pipe directly contacts flame, uses after 2-3 month and should locate scaling loss, and the material feeding of watering of filling is dropped because of losing to support in the burner, move behind the burner mouth flame location, continue to use the risk that gas explosion is arranged.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of fuel burner nozzle that is difficult for scaling loss, long service life at the deficiencies in the prior art.
The technical solution of the utility model is: comprise interior pipe, outer tube, liner; The ejiction opening place of described burner is provided with the refractory body of band endoporus; The endoporus of described refractory body communicates with pipe in the burner.
The endoporus of described refractory body is a stepped hole; The step macropore place of refractory body is connected with the burner outer tube; The step small aperture of refractory body is less than or equal to the burner inner tube diameter.
Described refractory body is the square or circular configuration of band circular inner hole.
Described refractory body is set in outside the burner outer tube.
Described refractory body is a tubular structure.
Described refractory body is set in the interior pipe of burner.
Described refractory body is integrally formed refractory brick.
The fixed form of described refractory body and burner can adopt refractory body to be enclosed within on the burner or a fixedly mode of the support of refractory body (being specially adapted to export burner straight up) is installed on outer tube.
There is a hole that diameter is littler than fuel burner nozzle diameter of inner pipe at the center of described refractory body, and refractory body is enclosed within the outer tube outside, becomes the part of burner; in use; the flame of burner directly contacts refractory body, does not contact interior pipe, thereby plays the effect of protection burner.The utility model can vertically be installed, level is installed or be certain inclination angle installs.Flame only contacts refractory body, and burner extends to 12 ~ 13 months service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1, outer tube, 2, liner, 3, interior pipe, 4, refractory brick, 5, air intake, 6, fuel inlet.
The specific embodiment
Among Fig. 1, pipe 3, outer tube 1, liner 2 in burner comprises.Burner is provided with fuel inlet 6, air intake 5, ejiction opening.Interior pipe 3, outer tube 1 all adopt seamless steel pipe, and the crack that forms between interior pipe 3 and the outer tube 1 adopts and waters the material feeding filling as liner 2.Put the refractory brick 4 of pouring into a mould well high temperature resistant, being difficult for scaling loss in the outside of the ejiction opening place of burner outer tube 1.Refractory brick 4 is the cube of band circular inner hole, and this circular inner hole is a stepped hole, and step macropore place is connected with burner outer tube 1, and the step small aperture is than the little 2 ~ 4cm of interior pipe 3 diameters.Refractory brick 4 highly is 5 ~ 5.5cm.
Among Fig. 2,1 is outer tube, and 2 is liner, and 3 is interior pipe, and 4 is refractory brick, and 5 is air intake.
During the utility model work, the flame part only contacts refractory brick.Water the material feeding cast and high temperature resistant because refractory brick adopts, burner extends to 12 ~ 13 months service life.
