Abstract
The invention discloses a forced-draft flameless combustor, which mainly solves the problems of incomplete gas combustion and black smoke rising of the conventional combustor. The forced-draft flameless combustor comprises a combustor main body, wherein an air inlet is arranged at the bottom of the combustor main body, and a combustion seat is arranged at the top of the combustor main body; a gas inlet pipe is arranged in a vertical part of the combustor main body; a gas inlet is arranged at the bottom end of the gas inlet pipe, and an internal nozzle is arranged at the top end of the gas inlet pipe; the combustion seat is formed by movably overlapping a plurality of layers of funnel-shaped structures; and an adjustable clearance is reserved between every two layers of funnel-shaped structures. By unique design of the forced-draft flameless combustor, gas can be completely combusted, temperature is uniform during the arrangement of a plurality of combustors, a disk-shaped blue flame can be formed, a process is safe, carbon absorption is avoided, the problems of back fire and black smoke rising are solved, and the forced-draft flameless combustor is particularly applicable to a cracking furnace.
Description
Technical field
The present invention relates to a kind of burner, specifically a kind of forced ventilation flameless burner.
Background technology
The application of burner in various Industrial Stoves is very extensive, and the burning seat of existing burner is divided into two kinds of cellular type and clearance types, and its mode of operation is that combustion gas feeds behind the burner body and the oxygen mix burning, the flame of generation from the through hole or the slit emerge.Said burner since flame from the through hole or the slit emerge and cause its temperature also inhomogeneous, the burning of combustion gas is also incomplete, flame is crocus, can produce over-emitting black exhaust and tempering phenomenon.In addition, because its non-uniform temperature, in use the higher point of temperature can produce and inhale the carbon phenomenon, influences the performance of equipment.For pyrolysis furnace, its temperature requirement to flame is higher, and existing burner is not well positioned to meet the requirement of pyrolysis furnace, therefore need a kind of temperature evenly, burning fully, the burner of process safety.
Summary of the invention
The object of the present invention is to provide a kind of forced ventilation flameless burner, the fuel gas buring of this burner is complete, flame temperature is even, has solved the problem of tempering, over-emitting black exhaust.
The present invention solves the technical scheme that its technical problem takes: a kind of forced ventilation flameless burner, comprise burner body, the bottom bend of burner body also is provided with air inlet in the end, the top is provided with the burning seat, it is characterized in that, the burner body vertically inside of part is provided with the fuel gas inlet pipe, and described fuel gas inlet pipe bottom is stretched out the outside of burner body and is provided with fuel gas inlet, and the top is provided with inner nozzle; The top of the inner inner nozzle of burner body is provided with a holder, and described burning seat is connected on the holder; Described burning seat is made of the movable stack of multilayer funnel-shaped structure, is provided with adjustable gap between every two-layer funnel-shaped structure.
One side of described air inlet is provided with the accent windshield plate, and the inside of described burner body is provided with air regulating board.
Be provided with bracing frame between the sidewall of described fuel gas inlet pipe and described burner body.
Described burner body is provided with mounting flange.
The present invention compared with prior art has following outstanding beneficial effect: combustion gas is from the inner nozzle ejection, and the chamber that sprays near the burning seat burns, and avoids producing tempering phenomenon under the effect of inner nozzle; The size of transferring windshield plate and air regulating board can regulate air quantity guarantees that combustion gas can completing combustion, makes it produce blue flame, has avoided the over-emitting black exhaust phenomenon that produces because of incomplete combustion; Burning seat is made of the movable stack of multilayer funnel-shaped structure, and flame is emerged from the gap between every two-layer funnel-shaped structure, the flames of anger when the outside is seen, and flame forms discoidly, and temperature is even, does not inhale carbon.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 burner body, 2 air inlets, 3 fuel gas inlet, 4 fuel gas inlet pipes, 5 mounting flanges, 6 bracing frames, 7 inner nozzles, 8 air regulating boards, 9 holders, 10 burning seats, 11 transfer windshield plate.
The specific embodiment
The invention will be further described below in conjunction with Figure of description:
As shown in Figure 1, a kind of forced ventilation flameless burner, comprise burner body 1, the bottom bend of burner body 1 also is provided with air inlet 2 in the end, the top is provided with burning seat 10, the burner body 1 vertically inside of part is provided with fuel gas inlet pipe 4, and described fuel gas inlet pipe 4 bottoms are stretched out the outside of burner body 1 and are provided with fuel gas inlet 3, and the top is provided with inner nozzle 7; The top of burner body 1 inner inner nozzle 7 is provided with a holder 9, and described burning seat 10 is connected on the holder 9; Described burning seat 10 is made of the movable stack of multilayer funnel-shaped structure, is provided with adjustable gap between every two-layer funnel-shaped structure.
One side of described air inlet 2 is provided with transfers windshield plate 11, and the inside of described burner body 1 is provided with air regulating board 8.The size of transferring windshield plate 11 and air regulating board 8 can regulate air quantity guarantees that combustion gas can completing combustion, makes it produce blue flame, has avoided the over-emitting black exhaust phenomenon that produces because of incomplete combustion.
Be provided with bracing frame 6 between the sidewall of described fuel gas inlet pipe 4 and described burner body 1.Because fuel gas inlet pipe 4 is elongated tubular structure, bracing frame 6 can play it and support firm effect, avoids it to take place in the course of the work to be offset and to rock, and guarantees the service behaviour of burner.
Described burner body 1 is provided with mounting flange 5.Mounting flange 5 is used for install combustion device main body 1.
During use, will transfer windshield plate 11 and air regulating board 8 to adjust to proper state, air enters burner body 1 from air inlet 2, and fuel gas enters fuel gas inlet pipe 4 and from inner nozzle 7 ejection from fuel gas inlet 3.Under the ejector action of inner nozzle 7, fuel gas and air can be above inner nozzle 7 near the chamber internal combustion of burning seat 10.The blue flame that burning forms is emerged from the gap between burning seat 10 every two-layer funnel-shaped structures, the flames of anger when the outside is seen, and flame forms discoid.Gap between every two-layer funnel-shaped structure can be adjusted, and satisfies the demand of people to the different structure form, to adapt to different payload.When a plurality of burners are arranged by rule, still can guarantee the even of its temperature like this, avoid suction carbon phenomenon, be particularly suited for pyrolysis furnace and use.
The above, principles more of the present invention just explain through diagrams, this specification be not be the present invention to be confined to shown in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
Except that the described technical characterictic of specification, all the other technical characterictics are those skilled in the art's known technology.
