Abstract
The invention relates to a combustor for industrial kilin which comprises air-inlet tube, oil-intake tube and combustion chamber. At the wall of the combustion chamber is provided with air inlets admitting air to blow in transversely corresponding to the fuel-oil, and the facing direction of the air-inlet is bias to the section center of the combustion chamber to make the combustion-assisting air form cyclone. Said invention features in simple structure, safety combustion, strong fire, heat-insulation and cocking-proofing etc..
Description
The present invention relates to a kind of industrial furnace burner, especially relate to a kind of pneumatic type burner.
In present burner, the atomization type burner comparatively more sees that this kind burner adopts high pressure throttling, oil atomizing structure mostly, and machining, also accurate especially to the technological requirement of burner, thereby the processing technology more complicated, and cost is also higher.
There are many professionals to attempt the structure of burner is improved, so that burner becomes simple in structure, sufficient combustion etc.As 89211871.7 utility model patents, a kind of straight tubular burner has been proposed, this burner is to adopt air to spray the oblique air that tapered sleeve ejects, and the mist of oil cone angle is shunk.But because spraying tapered sleeve, its air is installed on the oil-in place, thereby action effect and imperfect, structure is still very complicated simultaneously.
The object of the present invention is to provide a kind of pneumatic type burner simple in structure, the combustion air that is imported by the transverse air-intake mouth mixes with liquid fuel, makes fuel combustion abundant, and firepower is vigorous.
The object of the present invention is achieved like this.A kind of pneumatic type burner comprises combustion chamber, blast pipe and oil inlet pipe, and oil inlet pipe passes combustion wall, and row's mouth is positioned at combustion chamber.Combustion chamber has the air channel that is communicated with blast pipe outward, is furnished with the tuyere that laterally is blown into respect to fuel oil on the chamber wall of combustion chamber.When liquid fuel when oil inlet pipe flows in the chamber internal combustion, the air that is sprayed into by tuyere dispels fuel oil and mixes with air, and further meets with the combustion air that enters in the chamber with wind flow, reaches clean-burning purpose.
The tuyere that is furnished with on the combustion chamber can partly or entirely be the cavity cylinder, these can obliquely be installed on the chamber wall of combustion chamber for the tuyere of cylinder, the direction of cylindricality tuyere and the cross section of combustion chamber radially become angle, be that the direction that the direction of tuyere is advanced to the liquid oils materials flow tilts, the axle center of departing from oil inlet pipe is again pointed in the axle center of tuyere simultaneously, the air that tuyere is input into forms whirlwind at the central shaft of combustion chamber, whirlwind dispels fuel oil, mix with fuel oil, and form eddy flow and further fully mix with the air that is blown into, make the oil inflame better effects if.
The present invention is owing to adopted said structure, and fuel oil needn't add high pressure when flowing into combustion chamber, atomizes during ejection, the fuel oil that utilizes crosswind force will flow into combustion chamber dispels, and fuel oil is repeatedly fully mixed with air, and very big to the progradation of flame, thereby oil inflame is abundant, and firepower is vigorous.Adopted the thermal insulation fire-resistant material layer in the combustion chamber again, high insulating effect makes fuel oil in high temperature chamber internal combustion, and it is more abundant to burn, and prevents to tie charcoal, and the present invention simultaneously is simple in structure, easy to manufacture, thereby with low cost.
The present invention is described further below in conjunction with accompanying drawing.
Fig. 1 is the structure cutaway view of the embodiment of the invention.
Fig. 2 is the sectional view of combustion chamber of the present invention.
The pneumatic type burner comprises combustion chamber 3, blast pipe 2 and oil inlet pipe 1, combustion chamber 3 is a hollow cavity, cavity inner wall is anti-attached fiery material layer, oil inlet pipe 1 passes combustion wall from the rear portion of combustion chamber and enters combustion chamber, its oil drain out is positioned at combustion chamber 3, the length that oil inlet pipe 1 inserts in the combustion chamber is as the criterion to be lower than 1/4 of whole combustion chamber length, distance forms a passage between the outside of air inlet 2 and combustion chamber 3, air channel 7 is furnished with tuyere 4 on the chamber wall of combustion chamber 3, and the part of tuyere 4 is a cylinder, another part is the cloth air port, and cylindricality tuyere 4 can be installed on the chamber wall of combustion chamber 3 at interval with cloth air port 4.By air inlet 2 leaked-in airs through the air channel 7, again in tuyere 4 blows into combustion chamber 3, the liquid fuel that is flowed into by oil inlet pipe 1 is when combustion chamber 3 internal combustion, the air that is blown into by tuyere 4 will laterally blow to liquid fuel, the installation of cylindricality tuyere 4 becomes the angle of inclination with the central axis of combustion chamber 3, and the direction that the sensing that is to say these cylinder tuyeres 4 is advanced to the liquid oils materials flow tilts.During like this by oil inlet pipe 1 influent fuel oil, the air that these cylinder tuyeres 4 are input into dispels fuel oil, acts on fuel oil one thrust forward simultaneously, and air was fully mixed with fuel oil, strengthens the intensity of a fire again simultaneously, makes burning vigorous.These garden post tuyeres 4 tilt to be installed on the chamber wall of combustion chamber 3 again simultaneously, the sensing of cylindricality tuyere 4 deviates from the center of combustion chamber cross section, that is to say that the sensing of tuyere 4 deviates from the axle center of oil inlet pipe 1, the angle that departs from is 15, when each cylindricality tuyere 4 depart from oil inlet pipe 1 identical being when clockwise or counterclockwise of direction, the air that is input into by tuyere 4 is just at the fuel oil place, promptly the central shaft at combustion chamber forms whirlwind, owing to form whirlwind, make more abundant that air mixes with fuel oil, forward propulsion is stronger, thereby can make burning more abundant, and firepower is more vigorous.At this moment action effect is best.The part of tuyere 4 is the cloth air port, interts cloth on combustion wall, in order to replenish the input quantity of air, makes the more even of air input.The number of tuyere 4 and cylinder length can be according to the oil masses of fuel oil, and the size of combustion chamber 3 etc. design voluntarily.Cylinder tuyere 4 can be installed on the cross sections different on the fuel oil process direction with the cloth air port.Because oil inflame is abundant, firepower is vigorous, thereby reduces the possibility of finishing charcoal.
The inwall of combustion chamber 3, with thermal insulation fire-resistant material layer 5, for make tack good, can be earlier the nail of plastering be installed at the inwall of combustion chamber 3, reinforcing bar is first-class, and then smear one deck thermal insulation fire-resistant material layer, uncovered cleanliness is arranged on the surface of this heat-insulation layer, can make fuel oil keep the combustion chamber internal combustion of high temperature like this, thereby burning is more abundant, action effect is better always.
For preventing fuel oil drippage, pollution combustor, 7 li are provided with an oil-containing groove 6 in the air channel, and this groove can often clean, and changes to keep health.
Because this burner has adopted above mode, so fuel oil can be input in the oil pipe by natural fluid, and need not extraneous particular pressure, can achieve the goal.
