Definitions
- the present invention relates to a burner with several combustibles.
- the technical sector of the invention is the field of manufacture of industrial burners for rotary kilns.
- the present invention relates more particularly to a burner supplied with at least two different fuels: a first ordinary fuel known as rich, that is to say of PCI generally at least equal to 8000 kcal / Nm 3 , in solid form (pulverulent ), liquid or gaseous, and a second so-called lean fuel, that is to say a PCI of less than 8000 kcal / Nm 3 , in particular whose PCI is located in a range going from 0 to 3000 kcal / Nm 3 .
- a first ordinary fuel known as rich that is to say of PCI generally at least equal to 8000 kcal / Nm 3 , in solid form (pulverulent ), liquid or gaseous
- a second so-called lean fuel that is to say a PCI of less than 8000 kcal / Nm 3 , in particular whose PCI is located in a range going from 0 to 3000 kcal / Nm 3 .
- the second fuel (lean) is for example constituted by a gas resulting from the pyrolysis of metallurgical sludge, by a gas resulting from the fermentation of organic waste of animal origin or plant (“biogas”), by waste gases from production of chemicals, in particular installations petrochemicals, by gases resulting from the distillation of alcohol in particular, or a mixture of these poor gases; these poor gases have a Relatively low PCI and also variable depending on conditions of the installation from which they come; these gases can contain tars, acids and / or dust.
- biogas organic waste of animal origin or plant
- the burner described in this document also includes a flame stabilizer located at the end of the central duct, which has a flange-shaped hub and a central hole arranged in the extension of the oil spray nozzle; the hub has small openings and fins that guide the primary air coming out of these openings; the distance (measured radially) from outlet openings of the third and fourth annular duct by relation to the axis of the burner is at least equal to twice the radius of the central opening of the flame stabilizer; this configuration allows, by circulating in the central duct a small proportion (2 to 10%) of the primary air stream (the majority of this stream being delivered by the third and fourth "axial" air ducts and "Radial”), creating a "dead" central zone (without combustion noticeable) enlarged and the appearance of combustion to a greater distance in front of the nozzle.
- a flame stabilizer located at the end of the central duct, which has a flange-shaped hub and a central hole arranged in the extension of the oil spray nozzle; the hub has
- the object of the present invention is to adapt such burners designed for heating rotary ovens such as cement factories, to make them compatible with such fuels poor.
- the object of the present invention is to provide a burner allowing a reliable and rational use of these fuels mostly gaseous poor.
- the invention consists in proposing a burner which has two separate circuits for introducing (injecting) the lean fuel in the combustion chamber: a first circuit includes means for rotating the lean fuel, and a second circuit surrounds the first circuit and is substantially devoid of means for rotating the lean fuel; these two circuits are arranged outside the annular transport conduits "axial" and "radial" air, which are themselves arranged outside a central air transport duct terminated by a stabilizer flame, and outside of a rich fuel transport duct.
- Each of the two fuel (fuel) lines poor person is preferably fed by a nurse provided with an organ (such as a movable flap valve) for adjusting the fuel flow poor delivered to each conduit; this allows you to adjust the speed of ejection of the swirling jet (s) leaving the fifth conduit and the axial jet (or jets) (-aux) leaving the sixth conduit; the adjustment of these speeds - and of the flow rates - makes it possible to adjust the flow lean fuel injected into the combustion chamber of the furnace depending on its pressure, its nature, its temperature and its PCI, and prevents disruption of fuel combustion rich by lean fuel jets; the output speed of the lean fuel in the combustion chamber may be lower that of the rich fuel as well as that of the oxidizer injected between the rich fuel transport lines and the transport of lean fuel; in particular, the speed of lean fuel circulation is around 20 to 70 meters per second when the lean fuel is hot, i.e.
- a temperature of the order of at least 300 ° C. in particular of the order of from 300 ° C to 500 ° C
- is of the order of 20 to 30 meters per second when the lean fuel is cold that is to say at a temperature of the order from 0 ° to 100 ° C
- a minimum speed of approximately 20 meters per second is used to cause particle entrainment (dust) or droplets possibly present in the lean fuel.
- the kinetic energy (and / or the momentum) of the gas at low PCI should be as low as possible so as not to disrupt the combustion of rich fuel, and therefore do not change the shape too much flame; however the speed of the lean fuel must be sufficient to avoid the deposit of dust (in the case of a gas dusty), so generally more than 20 meters per second, and / or to avoid condensation of heavy tars (in the case of a pyrolysis gas).
- the two lean fuel transport circuits are designed to receive gas at a fairly high temperature (higher at 300 ° C). The temperature is chosen and kept above that of the deposition of the heaviest compounds.
- the nozzle can be preheated by passage of hot (clean) gases before the introduction of pyrolysis; preferably the internal (radial) transport circuit of the lean fuel is thermally isolated from the central part of the nozzle, in particular thanks to a double wall (filled stainless steel tube insulation).
- the outer tube of the oxidizer transport duct (axial), is also thus protected from heat by the insulation.
- the annular duct (the fifth duct) for transporting the lean fuel surrounding the annular duct (the fourth duct) for transporting the oxidizer is separated from the latter (fourth) led by an insulating layer thermal over a substantial part of its length; this allows avoid cooling (and / or limiting cooling) the fuel poor by oxidizer (air), which could cause condensation of condensable compounds and the deposit of condensate on the walls of the fifth lean fuel transport pipe; given that these deposits (acids, tars, dust) are likely to disturb the operation of the burner, and / or cause its corrosion, this thermal insulation can be made necessary.
- Figure 1 illustrates in front view the end 22 of the nozzle of the burner.
- Figure 2 is a half-view in section along the broken line A-A of Figure 1, on an enlarged scale.
- FIG. 3 schematically illustrates a setting wing rotation of the “internal” flow of lean fuel and is a view according to III-III of figure 2.
- Figure 4 illustrates in the same way as Figure 2 a burner of cement kiln, according to an alternative embodiment.
- nozzle 31 and the main conduits 5, 7, 9, 11, 15, 17 of the burner extend along a longitudinal axis 1; in the case of an oven cement plant, axis 1 can be substantially coaxial with the axis of the oven, in a horizontal position or slightly inclined with respect to the horizontal.
- the central part of the nozzle comprises a central duct 5 of air transport delimited by a tube 6 of axis 1; inside the duct 5 extend four conduits (Figure 2) parallel to the axis 1; a conduit 3 solvent injection, which is delimited by a tubular wall 4 of axis 2, as well as a conduit for transporting animal meal; products transported in these two conduits are intended to be incinerated in the oven combustion chamber; two other conduits are used for transport of combustible gas and waste water to be incinerated (and / or contain an ignition rod);
- a only fuel transportation conduit 3 is shown; conduit 3 is terminated by a fuel spray nozzle 3a.
- the tubes 6, 8, 10, 12, 16, 18 are respectively terminated at their free end by a sleeve 6a, 8a, 10a, 12a, 16a, 18a; these sleeves have a shape having a symmetry of revolution along axis 1; the thickness of the sleeves can be variable the along axis 1, to delimit annular (and / or flared) conduits for ejecting the products respectively transported in the combustion, which provide each with gaseous and / or pulverulent flows ejected into the chamber at a predetermined speed and direction; at this effect, in addition, fins 9a inclined relative to the axis 1 ensure a radial guidance of the air delivered by the conduit 9, for the formation in the room of a whirlpool; fins 11a parallel to axis 1 ensure axial guidance of the air delivered by the duct 11.
- the burner in the vicinity of its nose or front end 22 (of ejection in the chamber of combustion), includes fins 20 for deflecting the internal flow of lean fuel leaving the line 15, for training in the chamber of swirling jets around the air jets from the ducts 9 and 11, and comprises fins 21 for axially guiding the external flow of lean fuel leaving the duct 17.
- the nose has a ferrule 23 supporting the fins 20 which extend along a longitudinal axis 24, which is inclined to cause the flow leaving the duct 15 to rotate.
- the angle 25 of inclination of the axis 24 relative to the axis 1 is generally located in a range from 10 ° to 50 °.
- Pyrolysis gas is supplied to the pipes 15 and 17 of the nozzle by pyrolysis gas supply pipes, which are preferably respectively fitted with a valve 30 for adjusting the flow of pyrolysis gas introduced into each of the conduits 15, 17.
- the burner has an annular outlet opening 7b for solid and / or gaseous fuel, which is located radially inside the outlet openings 9b, 11b of the primary air rotated and of the axial air, and at the exterior of the flame stabilizer 5a; the stabilizer ( Figure 4) is disposed at the front end of a central oil nozzle holder; the minimum radial distance of the openings 9b, 11b for the outlet of most of the primary air from the center of the burner nozzle is at least twice the radius of the central opening of the flame stabilizer ( Figure 4); said stabilizer clearly protrudes in the radial direction relative to the opening of a central duct which corresponds substantially to the orifice of the nozzle 3a of the central fuel duct 3 (FIG.
- the annular supply conduits may have, upstream of their outlet opening, portions of conical walls (such as 7c, 7d, 11c, 11d) movable axially with respect to each other; some of the annular supply conduits may include an axial cylindrical end portion extending a portion of conical wall giving the end of the conduit an "S" shape (in longitudinal view).
- the annular channel 11 for the axial air comprises partitions 11a for the supply and the axial orientation of the primary air in separate channels, arranged on a ring and extending axially; the annular passage section for axial air or the corresponding channels arranged in a ring can be at least partially closed and closable; the sum of the free passage sections of the axial channels is substantially smaller than the section of the annular duct for the primary air flowing in the axial direction; the stabilizer 5a is axially offset backwards with respect to the outlet openings 9b, 11b of the rotating air and of the axial air, and with respect to the outlets 7b, 15b, 17b of solid or gaseous fuels, rich and lean.
- the opening 5c can, as a variant, be disposed at the periphery of the fuel spray nozzle 3a, or at any other position between the nozzle 3a and the wall 6 delimiting the central duct 5; this opening 5c can be delimited by two concentric tubular walls defining a fourth primary air supply duct independently of the three other conduits; this opening can facilitate the control of the mixture air-fuel in the central "dead" zone, reducing the reducing nature of the air / fuel mixture, and / or by improving this mixed ; one or more can be associated with this opening deflector wall (s) for guiding the primary air.
