Description
Technical field
The utility model belongs to petrochemical industry, is specifically related to a kind of bushing type burner.
Background technology
Bushing type burner belongs to exterior mixing burner, and its structure is simple, can be used for the combustion system of Heating Furnace.When fuel is gaseous fuel, air mixes with fuel gas the flame mechanism that process determines fuel, the mixing process of two kinds of air-flows mainly comprises mixing velocity and the mixing adequacy of two gas, if directly adopt bushing type burner, air and fuel gas form laminar flow respectively in outer tube and inner sleeve, outer tube and the port of export air of inner sleeve and the angle of cut of fuel gas very little, thus be difficult to realize rapid mixing and mix fully, thus affect burning quality, and may imperfect combustion be caused, reduce efficiency of combustion.
Summary of the invention
For the problems referred to above, the purpose of this utility model provides a kind of bushing type burner.
A kind of bushing type burner, comprises inner sleeve, outer tube, burner end cap, also comprises air ring cowling, showerhead; Described inner sleeve comprises pedestal from left to right successively, reducing type jet pipe and minor axis jet pipe; The front end welding showerhead of described minor axis jet pipe, the left end of described outer tube is threaded inner sleeve pedestal, the right-hand member of described outer tube is threaded burner end cap, weld air ring cowling between described burner end cap with minor axis jet pipe front end, described air ring cowling arranges trapezoidal aperture.
The centre of described pedestal arranges through hole, and described through hole is connected with reducing type jet pipe.
Described outer tube top arranges air intake.
Arrange spout in the middle of the right-hand member of described burner end cap, described spout is corresponding with showerhead.
Described inner sleeve, detachably, fuel gas enters through inner sleeve entrance, and then successively through reducing type jet pipe, minor axis jet pipe, obtains larger jet velocity.
Described outer tube, detachably, air is entered by air intake, then enters circular passage.
Described burner end cap, detachably, described burner end cap formed together with outer tube, inner sleeve air the circular passage of process, larger spouting velocity can be provided to fuel gas.
Described air ring cowling, arranges some trapezoidal apertures above, during air ejection, becomes thin stock flat stream to concentrate to centre ejection, makes fuel gas and the air mixing angle of cut larger, make mixing more abundant, improve burning quality.
Described showerhead, when fuel gas with larger speed through shower nozzle, can be formed divergent shape spray, accelerate two gas and vapor permeation.
Whole device, fuel gas enters from inner sleeve entrance, through reducing type jet pipe and minor axis jet pipe, creates larger flow velocity, and through showerhead ejection, air enters from air intake, and the slotted eye through air ring cowling sprays, and fully mixes with fuel gas.
The beneficial effects of the utility model are: structure is simple, deft design, and whole device makes fuel gas and the air mixing angle of cut larger, make mixing more abundant, improve burning quality.
Accompanying drawing explanation
Fig. 1 is the utility model burner generalized section;
Fig. 2 is the utility model showerhead front view;
Fig. 3 is the utility model air ring cowling front view;
In figure, 1 is through hole, and 2 is inner sleeve, and 21 is pedestal, and 22 is reducing type jet pipe, and 23 is minor axis jet pipe, and 3 is air intake, and 4 is outer tube, and 5 is burner end cap, and 6 is air ring cowling, and 7 is showerhead, and 8 is spout.
Detailed description of the invention
A kind of bushing type burner, comprises inner sleeve 2, outer tube 4, burner end cap 5, also comprises air ring cowling 6, showerhead 7; Described inner sleeve 2 comprises pedestal 21 from left to right successively, reducing type jet pipe 22 and minor axis jet pipe 23; The front end welding showerhead 7 of described minor axis jet pipe 23, the left end of described outer tube 4 is threaded inner sleeve pedestal 21, the right-hand member of described outer tube 4 is threaded burner end cap 5, weld air ring cowling 6 between described burner end cap 5 with minor axis jet pipe 23 front end, described air ring cowling 6 arranges trapezoidal aperture; The centre of described pedestal 21 arranges through hole 1, and described through hole 1 is connected with reducing type jet pipe 22; Described outer tube 4 top arranges air intake 3; Arrange spout 8 in the middle of the right-hand member of described burner end cap 5, described spout 8 is corresponding with showerhead 7.
After air enters outer tube by outer tube entrance 3, successively by annular reducing pipe, static air pressure is increased, then through tubule, air velocity increases, then by air ring cowling, air is made to be the ejection of multiply thread, under the effect of trapezoidal hole, change the direction of air-flow, air is concentrated to third side to ejection.Fuel gas enters inner sleeve by inner sleeve entrance 1, under Venturi effect, larger speed is reached in tubule, then through inner sleeve sprinkle nozzle, spray in multiply thread, in surrounding divergent shape, form the larger angle of cut with air stream, thus two air-flows are fully mixed fast, improve burning quality.
