(4) on Inner Wall of Combustion Chamber, add heat-resistant lining, increased the service life of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram of the poly-fiery piece of the present invention's S type porous of arranging;
In figure: 1 air inlet cylindrical shell, 2 altar lamp ignition modules, 31 fuel gas delivery mains, 32 fuel gas ring pipes, 33 fuel gas efferent ducts, 331 nozzles, 4 premixers, 41 hybrid chambers, 42 hole enlargement chambeies, 5 combustion chambers, 6 heat-resistant linings, 7S type porous is gathered fiery piece, 8 air admission holes.
The specific embodiment
For ease of understanding technology contents of the present invention, below in conjunction with accompanying drawing, technical scheme of the present invention is described further.
As depicted in figs. 1 and 2, a kind of ammonia mix flare burner, comprises air inlet cylindrical shell 1, altar lamp ignition module 2, fuel gas transport portion, premixer 4 and combustion chamber 5.Air inlet cylindrical shell 1, premixer 4 and combustion chamber 5 threes coaxially arrange.
Described premixer 4 comprises hybrid chamber 41 and the hole enlargement chamber 42 that is arranged on hybrid chamber 41 upper ends and is communicated with it.Hybrid chamber 41 is also coaxial setting with hole enlargement chamber 42.When gas enters hole enlargement chamber 42 by hybrid chamber 41, flow velocity slows down, and starts to be disperse state, can further guarantee the mixing uniformity of ammonia and fuel gas, guarantees the completing combustion of ammonia.
Described hybrid chamber 41 is arranged on the upper end of described air inlet cylindrical shell 1 and is communicated with air inlet cylindrical shell 1, and described air inlet cylindrical shell 1 has certain overhang in described hybrid chamber 41.Described combustion chamber 5 is arranged on the upper end in described hole enlargement chamber 42 and is communicated with hole enlargement chamber 42.On the inwall of described combustion chamber 5, being consolidated with one deck heat-resistant lining 6(is flame retardant coating, and it can adopt refractory metal material, also can adopt high temperature ceramic material etc.).The poly-fiery piece 7 of multiple S type porous is set in the upper end of described combustion chamber 5.Preferably described S type porous gathered to fiery piece in the upper end of described combustion chamber circumferential arrangement and surround a steady pyrosphere.
Described altar lamp ignition module 2 can have multiple, and is circumferentially distributed in the periphery of described combustion chamber 5, and the firing tip of described each altar lamp ignition module 2 is arranged on a certain correct position place at the upper end open place of described combustion chamber 5.
On the bottom of described hybrid chamber 41 and the sidewall of described combustion chamber 5, be provided with multiple air admission holes 8.
In order to prevent from adulterating, air-flow forms dead angle near the bottom of described hybrid chamber 41, secular stagnation below, can not get effective circulation, so offer air admission hole 8 in the bottom of described hybrid chamber 41, size, shape and the number of air admission hole 8 is to guarantee forming enough circulations as benchmark, according to the size of inlet air flow, air admission hole 8 can be made as to circle, bar shaped or annular.On the sidewall of described combustion chamber 5, be provided with air admission hole 8, object is to promote that fuel gas fully contacts with air with the mixed gaseous mixture of ammonia, makes burning more abundant, thoroughly solves the problem of remaining ammonia.The number of equally, set air admission hole 8, shape, size and location can ensure enough air inlets and be as the criterion.
The fuel gas ring pipe 32 that described fuel gas transport portion comprises fuel gas delivery main 31, be communicated with described fuel gas delivery main 31 and be circumferentially distributed in the multiple fuel gas efferent ducts 33 that are communicated with on described fuel gas ring pipe 32 and with fuel gas ring pipe 32.Described fuel gas ring pipe 32 is nested with the periphery at described air inlet cylindrical shell 1.
The nozzle 331 of described fuel gas efferent duct 33 radially tilts to the axle center of described air inlet cylindrical shell 1 and extends axially up in described hybrid chamber 41, and described nozzle 331 is reducing form.The inclination angle of the axial relative level face of nozzle 331, guarantee that the fuel gas jet being penetrated by described nozzle 331 is injected in the position more than upper surface of described air inlet cylindrical shell 1.Preferably, the spout of described nozzle 331 is distributed in same level, and this horizontal plane is placed in described air inlet cylindrical shell 1 a distance, top, upper surface.
Fuel gas stream is entered after described fuel gas ring pipe by described fuel gas delivery main 31, penetrated by the nozzle 331 of each fuel gas efferent duct 33 respectively, because described nozzle 331 is reducing form, so have certain acceleration when fuel gas ejection, swiftly flowing fuel gas stream has strong perturbing property, impulse speed is very high, is conducive to fuel gas stream and mixes with intersecting of ammonia air-flow.And, when fuel gas is ejected by nozzle 331, there is certain axial velocity, this axial velocity can be accelerated the axial flow of the mist forming after fuel gas mixes with ammonia, thereby strengthen the air capacity of being introduced by hybrid chamber 41 bottom inflow holes 8, (fuel gas, ammonia and air three's mixing is again in combustion chamber 5 parts, the air of being introduced by the air admission hole 8 on combustion chamber 5 to realize fuel gas, ammonia and air three's first mixing; Three's the lighting-up tuyere place that is blended in combustion chamber 5 for three times).
Particularly the spout of nozzle 331 is distributed in same level, and this horizontal plane is in described air inlet cylindrical shell 1 a distance, top, upper surface, the fuel gas of ejection forms an annular, form strong turbulent flow with the ammonia being entered by described air inlet cylindrical shell 1 lower port, further promote the mixing uniformity of fuel gas and ammonia, increase flammable; Particularly, can promote to a great extent fuel gas to mix the axial flow velocity of the rear mist forming with ammonia, further strengthen the air capacity of being introduced by hybrid chamber 41 bottom inflow holes 8, improve the burn-off rate of ammonia.Mix rich fuel gas and ammonia gas mixture body, carry out after premix at hybrid chamber 41, enter hole enlargement chamber 42, because the cavity in hole enlargement chamber 42 makes to expand gradually, so failing to be convened for lack of a quorum, gaseous mixture forms a diffusion gas field, its flow velocity can slow down to some extent, and in this process, mixed airflow spreads fully, is conducive to the homogenising of gaseous mixture; After the Homogenization Process in hole enlargement chamber 42, mixed airflow enters described combustion chamber 5, is finally lighted completely.
Foregoing description basic principle of the present invention, principal character and advantage.For a person skilled in the art, it should understand the present invention and not be subject to the restriction of above-mentioned embodiment, and it is as a kind of embodiment of the best, and object is explanation technical characterstic of the present invention and principle.Protection scope of the present invention is defined by its claims.In the situation that not departing from design philosophy of the present invention and scope, those skilled in the art, in conjunction with known property general knowledge, can make multiple change or be equal to replacement, and they all should fall within the scope of protection of the present invention.
Except the technical characterictic described in description, be the known technology of those skilled in the art.
