Definitions

  • the present invention relates to a fluid mixture combustion device, which makes it possible to obtain a high dilution ratio between an inducing fluid and one or more induced fluids; this device is particularly suitable as burners-torches industrial burnable fuels or residual gases in the best condi- TIOR s, and burners which can work with a high discharge pressure (combustion in a submerged position of the burner, for example).
  • the invention aims to improve such induction burners in order to allow in particular their application in large dimensions such as torch burners intended to burn combustible fluids such as coal or finely atomized fuel oil in air or l oxygen, or residual gases in industrial units - petroleum refineries, steel factories (blast furnace gas) - or in order to burn gases from the gasification of coal.
  • torch burners intended to burn combustible fluids such as coal or finely atomized fuel oil in air or l oxygen, or residual gases in industrial units - petroleum refineries, steel factories (blast furnace gas) - or in order to burn gases from the gasification of coal.
  • the combustion device In such applications as burners: industrial torches, the combustion device must be able to operate efficiently, that is to say ensure complete combustion of combustible materials, with a wide variety of gases, ranging from the heaviest ( butane) to the lighter (methane, refinery gas with a high hydrogen content) or ranging from the poorest gases (poor or medium gas from the gasification of coal) to the richest gases.
  • gases ranging from the heaviest ( butane) to the lighter (methane, refinery gas with a high hydrogen content) or ranging from the poorest gases (poor or medium gas from the gasification of coal) to the richest gases.
  • the ratio between the induced air flow and the flow of gas to be burned, acting as the driving gas, must at all times be greater than or equal to the stoichiometric ratio, so that the burner can operate completely independently , without additional external air supply, even if the flow and pressure of the engine gas vary suddenly in large proportions, as occurs frequently in industry.
  • the burner must, moreover, be able to work efficiently with a discharge overpressure, which, naturally, reduces the induction of atmospheric air. However, this remains sufficient to ensure combustion with excess air in many operating cases.
  • the burner can therefore find application when one wants to carry out a submerged combustion, in which it is necessary to overcome a significant pressure drop.
  • the burner must be equipped with a flame catching device which is effective for a large range of excess air and a wide variety of combustible gases and which does not cause excessive pressure drops additional to the burner nose.
  • the device according to the invention can also be used with steam as the working fluid; the induced fluids are then in principle atmospheric air, and the gas to be burned.
  • This device can then operate as a particularly efficient torch burner insofar as the introduction of steam under pressure makes it possible to considerably increase the induction of air, and to catalyze the combustion reaction.
  • the device according to the invention can finally be used with air or oxygen as the working fluid; the induced fluid or fluids are then combustible fluids.
  • This device can then operate in a manner known per se as a gasifier.
  • the device according to the invention aims to satisfy these various requirements.
  • the subject of the invention is a combustion method according to which a gaseous working fluid is injected at one end of a profiled body open to the atmosphere at its two ends and forming a venturi, so that said gaseous working fluid driven by induction of one or more fluids induced in said body, the resulting mixture being burned at the other end of said body, this process being characterized in that the injection of said working fluid is carried out in said body at least a ply of annular cross section.
  • the Applicant has, in fact, established that such an injection of gaseous fluid in the form of at least one ply or of a veil with annular section, has the effect of considerably increasing the contact surface with the induced fluid, which results in a very high training rate.
  • the induced fluid will be entrained not only at the periphery of the ply of annular cross section, but also along its internal surface, at least one inlet being provided for this purpose in the central part of the injection ring, which will double the exchange surface between fluids.
  • each annular injector is dimensioned, positioned and profiled so as to constitute a body of the tube for the injection nozzle which is located upstream in the flow.
  • the profiled body of the device according to the invention may comprise, in a known manner in the evening, an inlet for induced gaseous fluid, preferably circular, but which may be a simple frustoconical cone converging in the direction of flow of the gas flow, a cylindrical mixer coaxial with said inlet and connected thereto, a truncated cone diverging in the direction of flow in gas flow, this divergent being coaxial with said mixer and connected to it.
  • the diverging part of the body of said device will have the shape of a frustoconical corner with an apex substantially equal to 7 ° relative to the central axis.
  • the Applicant has observed, in fact, that the efficiency of the diffuser (ratio of potential energy recovered to kinetic energy lost) is maximum for an angle at the top of 7 ° relative to the central axis.
  • the diverging part can end in a flared profile, which makes it possible to reduce the size of the burner and to further increase the efficiency.
  • the exit angle of the divergent in this case, is at most 20 °.
  • the means for injecting the pressurized gaseous fluid will comprise one or more annular injectors disposed at the upstream end of the body of the burner.
  • these injectors will be arranged along the axis of said body and the injectors of increasing section will be offset from upstream to downstream along said axis.
  • the annular injector or injectors preferably have a restriction or neck upstream of their orifice and their dimensions are such that the speed of the working fluid at the neck is equal to that of the sound in this fluid. If it is desired to obtain high dilution rates and if there is fluid under high pressure, this is injected into the body of the device with a largely supersonic expansion rate.
  • the annular section of the injector will thus have a convergent-divergent profile and the Applicant has established that it is desirable that the exit angle of the divergent from the injector is equal to approximately 24 °.
  • the outlet section of the injector is then equal to its section at the neck.
  • the ratio R between the section at the annular neck of each injector and the section of each mixer should be very low (0.0033, ⁇ R ⁇ 0.033).
  • an additional induced fluid inlet will be present in the central part of each injector, in order to double the exchange surfaces.
  • the flame catcher will therefore be of the aerodynamic type with opening and it will include for this purpose two coaxial cylinders of unequal length joined by an annular part, the shortest cylinder, open at its two ends, being connected to the end of the diffuser. , preferably by means of a cylindrical element forming stabilizer of the speed of the fluids, the annular part joining the two cylinders being perpendicular to the axis of the burners.
  • the longer outer cylinder promotes the establishment of a stable flow regime. It is connected to a conical opening angle at the top between 10 and 35 °.
  • the profile of the flue can be scalable with a cylindrical radius of curvature, so that the angle at the final apex of the flue is equal to 180 °.
  • the flame adheres to the wall of the refractory pipe, by Coanda effect.
  • This workpiece, heated at high temperature, radiates towards the charge to be heated.
  • the ignition of the fluids takes place at the end of the internal cylinder thereof, while a recirculation of the fumes occurs between the two cylinders and brings the combustible mixture to a temperature above its ignition temperature.
  • Two or more passages can advantageously be provided in the internal cylinder of the flame catcher, so as to supply a combustible mixture to the smoke recirculation zone.
  • one or more fresh air intake orifices may be provided in the external cylinder.
  • the quantity of fluid induced in such a burner is such that the dilution rate, that is to say the ratio of the mass flow of induced fluid to the mass flow of working fluid, is clearly greater than unity and can reach values greater than 50, whatever the supply pressure, while obtaining a perfectly stable flame.
  • the injectors of annular sections can be produced in a manner known per se: they can also be advantageously replaced for reasons of simplicity of construction by one or more bundles of cylindrical tubes arranged in rings on the outer surface a metallic or refractory skirt which fulfills the function of the body of the horn described above.
  • the device according to the invention can be advantageously used in industry in all techniques using industrial burners or gasifiers, for example in heat treatment furnaces, in refinery furnaces or flares, glassworks, furnaces ceramic, in processes with submerged combustion or when the burnt gases must overcome a high pressure drop, as well as in the gasification processes of coal or petroleum residues.
  • the burner shown in FIG. 1 comprises two induced fluid inlets 1, arranged upstream in the direction of flow of the gas and delimited by a converging profile, which may possibly be frustoconical. Each profile is connected to a cylindrical portion 2, forming a mixer, extending by a divergent 3, in the form of a truncated cone forming a diffuser.
  • the diverging portion of the burner body may have a profile 3a which widens regularly downstream in the manner of a trumpet, which increases the efficiency of the diffuser.
  • the exit angle 0 ′ of the divergent 3a is at most equal to 20 °.
  • a cylindrical chamber 4 serve as a stabilizer intended to homogenize the speed of the gases.
  • the chamber 4 is provided, at its downstream end, with an aerodynamic type flame catcher, which will be described in more detail below.
  • the inlet of the working fluid is effected by a nozzle 6 with annular section.
  • the nozzles 6 are pierced along the axis of a conduit 8, open at their two ends and which communicate with the atmosphere through their downstream end.
  • the air supply is carried out in the usual way by entrainment by the combustible gas, which acts as a driving agent, but, the gas being injected under pressure and at high speed in the form of a sheet cylindrical or conical, in contact with the air both by its external part and by its internal part, diffusion and mixing with the air occur very quickly, with a minimum pressure drop in contact with the walls.
  • a variant of this gas burner type application consists in supplying the device shown in FIG. 1 with a working fluid consisting of pressurized steam in place of the combustible gas.
  • the induced fluids are then the combustible fluid and the atmospheric air which can be introduced as a mixture or separately.
  • the flame catch 5 disposed at the downstream end of the stabilizer 4 is of the aerodynamic type and comprises two coaxial cylinders 5a, 5b, joined by an annular part 9 perpendicular to the axis of the stabilizer 4.
  • the cylinder 5a open at its two ends, is arranged in the extension of the stabilizer 4. Its walls are pierced with orifices 10, allowing the passage of the combustible mixture in the interval separating the cylinder 5a from the cylinder 5b.
  • the latter is longer than the cylinder 5a.
  • It is extended by a frustoconical opening 11 which diverges in the direction of flow, with an apex angle p of between 10 and 35 °.
  • the profile of the opening 12 can be evolving cylindrical with an angle at the final vertex of 90 ° relative to the axis.
  • the initial ignition of the air-gas mixture arriving through the stabilizer 4 and the continuous re-ignition of the flame are ensured by the recirculation, in the space separating the two cylinders, of high temperature fumes, which bring the combustible mixture to a temperature higher than its ignition temperature. Because no material obstacle is placed on the path of the gas mixture, it does not undergo significant pressure drops.
  • FIG. 3 A preferred embodiment of an annular injection nozzle appears in FIG. 3.
  • the wall of each injector closest to the axis X'X, is substantially cylindrical and ends in a diverging angle of angle e substantially equal to 7 °.
  • the other wall has a protuberance defining with the adjacent wall a neck 7 separating a convergent from a diverging angle of angle ⁇ 2 between 0 and 24 ° (0 ° in the case where the gas pressure is low, and the flow is subsonic, and 24 ° in the case of a sonic flow at the neck and largely supersonic in the divergent).
  • the values to be adopted vary according to the gas considered, its temperature and its pressure, and it is therefore desirable to be able to easily replace one or more injectors of the same burner.
  • Figure 4 shows a detailed view of the entire fluid injection section here comprising three injectors.
  • Example 1 illustrates the dilution effect which can be obtained on gas burners fitted with injectors described above.
  • FIG. 5 relates to the injection of methane with an annular injector having a slit width of 0.1 mm.
  • the dilution rate Q "/ Q ' is very high and clearly higher than the stoichiometric ratio. It is however necessary to operate under an injection pressure of at least 3 bars relative, because, at lower pressure, the quantity of induced air is too high, which results in mixing conditions between methane and air, such that one is outside the flammable boundary conditions, in which case the latter must be artificially reduced the induced air flow by means of an adjustable intake window.
  • FIG. 6 reports tests carried out with ethane and an annular injector with a slit width equal to 0.1 mm.
  • the dilution rate is equal to or greater than the stoichiometric ratio and there is an excellent adaptation of this ratio to the injection pressure.
  • the flame is perfectly stable throughout the pressure range.
  • FIG. 7 relates to propane tests with an annular injection slit of 0.1 mm. of width.
  • Q also, the dilution ratio is generally higher to the stoichiometric ratio, although it tends to decrease at high pressures.
  • FIG. 8 relates to similar tests carried out with butane and an annular injector with a slit width equal to 0.1 mm. These tests show that the dilution ratio is very close to the stoichiometric ratio.
  • FIG. 9 relates to other tests carried out with methane and an annular injector with a slit width equal to 0.2 mm. This figure is therefore to be compared with FIG. 5, which relates to similar tests carried out with an injection slot of width equal to 0.1 mm. In this case, too, the report adapts well to pressure variations and remains close to the stoichiometric ratio. The flame is perfectly stable throughout the supply pressure range.
  • Example 2 illustrates the advantage of the device according to the present invention when using a working fluid consisting of steam under pressure.
  • Curve A in FIG. 10 relates to the injection of steam as a working fluid with an annular injector having a slit width of 0.1 mm.
  • the combustible gas is induced in the axis of the device, and the induced air arrives at the periphery of the annular injector.
  • This curve A shows that the dilution rate obtained is very high and can commonly reach values from 30 to 50.
  • annular injection of example 2 was replaced by a bundle of 8 tubes of 2mm diameter at the neck arranged in a ring on a metal skirt of diameter equivalent to that of example 2.
  • Curve B of FIG. 10 relates to the results obtained with this type of injector by annular bundles of tubes. These results show the equivalence of the results with those of the previous example.
