Definitions
- the invention relates to a co-current and fixed bed gasifier for the gasification of a carbonaceous solid fuel, such as, for example, solid biomass. More particularly, the invention relates to such a gasifier comprising a vertical tank having successively and from top to bottom: an inlet lock for introducing the fuel into the tank,
- a pyrolysis zone for pyrolyzing the fuel introduced into the tank and comprising first means for admitting a pyrolysis agent
- a combustion zone for burning pyrolysis gases originating from the pyrolysis zone and comprising second means for admitting a gasifying agent
- Said tank further comprises active transfer means for actively transferring solid material from the pyrolysis zone to the reduction zone, said active transfer means being located between the pyrolysis zone and the combustion zone.
- the active transfer means are located in the tank between the place where the first admission means of the pyrolysis agent are provided for admitting said pyrolysis agent in the tank and the place where the second intake means of the gasifying agent are provided to admit said gasifying agent in the tank.
- pyrolysis agent it is necessary to understand a neutral or reactive gas which will provide the energy necessary for the temperature rise of the solid fuel contained in the pyrolysis zone. This energy can be either carried by the gas itself or be generated by the reaction of gas with the products contained in the pyrolysis zone.
- Said pyrolysis agent may therefore for example be preheated ambient air, a gas with a higher concentration of oxygen, water vapor, carbon dioxide, a fuel gas or a mixture of these gases.
- gasifying agent it is necessary to understand a gas capable of reacting with the carbon and / or with the hydrogen contained in the solid fuel.
- Said gasifying agent may therefore for example be ambient air, a gas with a higher oxygen concentration. , water vapor, carbon dioxide or a mixture of these gases.
- the invention also relates to a gas production and combustion unit comprising such a gasifier for producing said gas.
- a gas production and combustion unit comprising such a gasifier for producing said gas.
- Such gasifiers are known and make it possible to produce a combustible gas from a carbonaceous solid fuel, in particular from wood waste, such as those originating, for example, from sawmills or from forestry operations, or from - agricultural products (straw, etc.), or from recycled wood.
- This combustible gas contains in particular carbon monoxide and hydrogen and can then be used for various purposes such as, for example, for supplying a gas turbine or an internal combustion engine or a boiler or an oven.
- most known co-current gasifiers provide a gas also comprising a significant amount of tars, which can adversely affect the operation of machines using such gas as fuel.
- Various solutions have therefore been proposed to reduce the tar content of the gas produced by such gasifiers.
- EP 1248828 discloses, for example, a gasifier in which a void space (i.e., a solid-free zone) is created in the combustion zone in order to obtain better combustion of the pyrolysis gases as well as better gasification of the pyrolyzed mass, which reduces the tar content of the gas at the outlet.
- a void space i.e., a solid-free zone
- this patent proposes to provide the lower portion of the reduction zone with a mechanism for controlling the transfer of solid material between the reduction zone and the ash collection zone.
- the lower part of the pyrolysis zone is also provided with funnels and a mobile grid to more or less measure the amount of solid fuel entering the combustion zone.
- Such a system has the disadvantage that, given the very random nature of solid flows, it is possible for material not yet completely pyrolyzed to enter the combustion zone. In addition, it is also possible that material not yet completely reduced enters the ash collection area. Indeed, in the case where the flow of material entering the combustion zone is faster than expected, the material transfer means to the ash collection area will open more strongly to maintain the empty space in the combustion zone.
- this inflow can vary depending on the circumstances, for example depending on the physical characteristics of the biomass used (particle size for example) and / or instantaneous characteristics of the flow.
- the patent NL-8200417 discloses a similar gasifier and proposes to provide the lower part of the pyrolysis zone with a mechanism for transferring solid matter from the pyrolysis zone to the reduction zone while leaving a gap between these zones. two areas.
- This solid material transfer mechanism comprises a cone placed at a distance from a corresponding conical neck of the tank and being able to be rotated and / or in axial movement in order to agitate the solid material so as to transfer it to the reduction zone. .
- fuel not yet completely pyrolyzed enters the combustion zone.
- An object of the invention is to at least partially solve the problems of known gasifiers.
- the gasifier according to the invention is characterized in that the active transfer means comprise a transfer lock capable of preventing a direct flow of the solid material from the pyrolysis zone to the reduction zone, said transfer airlock. being permeable to pyrolysis gases.
- a transfer airlock also makes it possible to better regulate the flow rate of solid material poured into the reduction zone and is thus better to ensure a void space (that is to say a zone free of solid matter) above the reduction zone. which also helps to reduce the amount of tars in the exhaust gases.
- the transfer lock comprises a first turntable having at least a first off-center opening and a second turntable having at least one second off-center opening, the two plates being arranged horizontally and at a distance from one another, thus defining a transfer zone between the two plates, each of the first openings being offset horizontally with respect to each of the second openings, and the transfer zone is provided with a first fixed obstacle relative to the tank.
- a preferred device makes it possible, thanks to the decentering and the rotary movement of the first opening, to better distribute the solid fuel sample in the pyrolysis zone. This device thus makes it possible to better approach an ideal flow of the "LILO" type (Last In Last Out) of the solid material in the pyrolysis zone and thus contributes to making the pyrolysis even more complete.
- this preferred device makes it possible to distribute the solid matter more evenly over the bed of material in the reduction zone, which contributes to a better gasification.
- a more uniform distribution makes it possible to avoid preferential paths for the gas flow through the reduction zone, which would otherwise lead to a lower completion of the reduction reactions between solid particles and gas flows by a too fast passage of said flows. gaseous in the reduction bed.
- the first obstacle is fixed with respect to the tank, this has the effect of preventing at least a portion of the solid material from being rotated by the rotation of the first and / or second plate, which allows effective emptying of the transfer zone through the second opening.
- the first rotary plate is surmounted by a second fixed obstacle relative to the tank in order to prevent at least a portion of the solid material located in the pyrolysis zone from being rotated by the rotation of the first plateau, which would disturb otherwise the flow as desired of the material in the pyrolysis zone.

- Fig.1 shows schematically a frontal section of a gasifier (1) according to the invention.
- This gasifier is formed by a reactor in the form of a vertical vessel (4) comprising successively and from top to bottom:
- a pyrolysis zone for pyrolyzing the biomass introduced into the tank and comprising first means for admitting a pyrolysis agent (11),
- the biomass (2) for example wood chips, is introduced into the tank (4) from above by means of the inlet lock (5) (for example a rotary valve) and thus enters the pyrolysis zone ( 10) where it decomposes, under the effect of heat, into volatile matter and into a carbon-rich solid residue generally called
- Said gas may, for example, be an oxygen-containing reactive gas which, by burning a fraction of the biomass or products of the decomposition of the biomass, will release the energy necessary for the pyrolysis. It can also be an inert gas (such as carbon dioxide, nitrogen, water vapor) which, preheated, will provide the energy necessary for pyrolysis. It can also be a combination of both types of gas.
- the vessel also has active transfer means for actively transferring solid material (essentially "char") from the pyrolysis zone (10) to the reduction zone (30), said transfer means being located between the pyrolysis (10) and the combustion zone (20).
- the active transfer means are located in the tank between the place (11a) where the first means (11) for admitting the pyrolysis agent are provided for admitting said pyrolysis agent in the tank and the place (21a) where the second means (21) for admitting the gasifying agent are provided to admit said gasifying agent in the tank.
- These active transfer means comprise a transfer lock (50) able to prevent a direct flow of the solid matter (2) from the pyrolysis zone (10) to the reduction zone (20).
- transfer means therefore have a dual function: on the one hand, they provide a physical separation for the solid material (2) between the pyrolysis zone (10) and the rest of the reactor (zones 20, 30, 40), and on the other hand they actively control the flow of solid material (2) between these two parts of the reactor (4). It should be noted that these transfer means must allow the passage of volatile materials from the pyrolysis zone to the combustion zone in order to be burned. In other words, said transfer lock is permeable to the pyrolysis gases.
- the volatile materials (also called “pyrolysis gases”) entering the combustion zone (20) are burned partially or totally at the level of the second means for admitting a gasifying agent (21).
- These second intake means of a gasifying agent may for example comprise a plurality of nozzle (s) opening laterally into the tank at the combustion zone. This combustion produces essentially carbon dioxide (C0 2 ), water (H 2 O), and of course heat. Typically, temperatures above 1100 ° C are attainable in the combustion zone.
- the "tank” that has been transferred to the reduction zone will react with the combustion products to form carbon monoxide (CO) and hydrogen (H 2 ).
- this reaction typically occurs in a temperature range. between 300 ° C and 800 ° C. This temperature may nevertheless be higher and reach or even exceed 1300 ° C in the case where a higher carbon fuel is used and / or preheated reagents are used.
- the gases produced by this reaction will be collected at the outlet (6) of the reactor which is located in the bottom of the tank (4). There is thus at the outlet (6) a fuel gas typically comprising about 15% to 30% CO, 10% to 25% of H 2 , 0.5 to 3% of CH 4 , 5% to 15% of C0 2 and 49 % N 2 when using ambient air as a gasifier.
- the ashes will be harvested in the bottom (40) of the tank.
- transfer lock device (50) Apart from the transfer lock device (50), such gasifiers are known and therefore will not be entered in more detail in their design or operation. Attention will now be focused on the transfer lock (50), examples of which will be provided hereinafter.
- Fig.2 shows a frontal section of an embodiment of a gasifier according to the invention.
- the transfer lock (50) here comprises a hopper (55) under which is mounted a worm (56) driven by a motor (M), said screw being surrounded by a cylindrical piece (57) opening into the combustion zone .
- This transfer lock therefore makes it possible to actively transfer the "tank” from the pyrolysis zone (10) to the reduction zone (30), while preventing a direct flow from the "tank” of the pyrolysis zone to the reduction zone.
- the flow rate of "char” may for example be adjusted by acting on the speed of rotation of the motor (M). In particular, this flow rate will be adjusted so as to leave permanently a solids vacuum above the reduction zone.
- the control of the motor speed (M) can be done in a closed loop.
- Presence detectors for solid matter in the combustion zone can be used for this purpose.
- Other material transfer mechanisms may be envisaged, such as, for example, a double sliding door lock (for example an entry door directed towards the pyrolysis zone and an exit door directed towards the combustion zone, the entrance door is open when the exit door is closed and vice versa, it is also possible to envisage several entry doors and several exit doors), in which case the "char" flow rate can be adjusted by acting on the opening and closing rhythms of said entry and exit doors.
- said inlet and outlet doors can not be gastight because the transfer lock must be able to let the pyrolysis gases pass continuously.
- the material transfer means comprise a transfer lock, of which an inlet (pyrolysis zone side) is formed by a plurality of transverse bars spaced and parallel to one another, at least one of said bars being rotatable and preferably having a polygonal section (for example a square section), and an output (combustion zone side) is formed by one or more movable flaps.
- the distance between two adjacent bars as well as their respective sections will be designed such that, in the absence of rotation of the rod (s) which is (are) rotatable among said two adjacent bars, the solid material remains blocked above said two adjacent bars by a vault effect resting on said two adjacent bars.
- Fig.3 shows a frontal section of a preferred embodiment of a gasifier according to the invention.
- the transfer lock (50) here comprises a first turntable (51) having at least a first opening (61) and a second turntable (52) having at least a second opening (62).
- the two plates are arranged horizontally and at a distance from one another, so as to form a transfer zone between the two plates.
- the two plates are preferably connected to a central shaft (100) vertical axis Z can be rotated, for example by means of a motor (101).
- the two openings (61, 62) are off-center with respect to the Z axis and they are also horizontally offset relative to each other, so that the "tank" (2) can not pass directly from the pyrolysis zone (10) to the reduction zone (30).
- the first openings (61) of the first plate are designed not to cover the second openings (62) of the second plate.
- the trays (51, 52) have a circular shape and the tank (4) has a circular cross section whose diameter at the trays is slightly greater than the diameter of the trays.
- the transfer zone between the two plates is also provided with a first obstacle (70) fixed relative to the tank. It may be for example one or more transverse bar (s) attached (s) directly or indirectly to the tank (4). This obstacle makes it possible to prevent the solid material from being driven by the rotational movement of the second plate (52) and thus to force said material to pass through the second opening (62) when it arrives opposite the second opening.
- Fig. 4 shows a cross sectional view (AA) of the gasifier of Fig. 3.
- the first fixed obstacle comprises at least a first fixed crosspiece extending radially relative to the plates.
- the motor (101) may have a continuous rotary motion or a clockwise-counterclockwise oscillating movement. In the case of a continuous rotary movement, the rotational speed of the motor will for example be of the order of 5 to 15 revolutions per hour.
- the motor (101) will be slaved to the "char" demand in the reduction zone (30) and so as to maintain a vacuum above the material bed in the reduction zone. To this end, it is possible to provide a high level sensor and a low level sensor of "char" in the reduction zone and to control the motor (101) so that it starts to rotate when a low level is detected and for it stops when a high level is detected.
- Fig. 5 shows a cross sectional view (AA) of a preferred embodiment of the gasifier of Fig. 5.
- the first fixed obstacle comprises at least a first fixed cross member (71) extending radially relative to the plates and furthermore at least one other cross member (72) angularly offset relative to the at least one first cross member (71) and extending partially radially from the outside to a center of the trays.
- the other cross member (72) extends about half of a radius of a tray (51, 52). This other cross (72) prevents the material from accumulating to the right of the first cross
- FIG. 6 shows a frontal cut of a more preferred embodiment of a gasifier according to Fig.3.
- the first plate (51) is surmounted by a second obstacle (80) fixed relative to the tank, such as a radial cross member for example.
- This second obstacle makes it possible to prevent the solid material (2) in the pyrolysis zone (10) from being rotated by the rotational movement of the first plate (51) and thus to ensure a more homogeneous flow. (LILO) matter from top to bottom.
- the second fixed obstacle is mounted so as to be aligned relative to the first fixed obstacle in the direction of the vertical axis Z.
- the first fixed obstacle comprises for example four radial crosspieces (71) as illustrated in FIG. FIG. 5
- the second fixed obstacle will preferably also comprise four radial crosspieces aligned vertically with respect to the four radial crosspieces (71) of the first obstacle.
- Fig.7 shows a frontal cut of a more preferred embodiment of a gasifier according to Fig.3.
- the vessel (4) further comprises shearing means (90) for shearing, in a transverse plane, the solid material (2) located in the pyrolysis zone (10).
- these shearing means (90) are located just above the second obstacle (80).
- These shearing means make it possible to prevent the formation of vaults of solid matter (2) in the pyrolysis zone, by breaking the bases of these vaults which generally rest on the second obstacle (80). This results in a more homogeneous flow (“LILO”) of the material.
- LILO homogeneous flow
- the shearing means comprise a movable knife (91) extending substantially horizontally in the vessel (4).
- the knife (91) is attached to the central shaft (100) so that it can be rotated by the latter.
- the knife (91) can be rotated or translated by own drive means.
- the invention also relates to a gas production and combustion unit comprising a gasifier as described above for producing said gas. It can act for example an assembly comprising a gasifier as described above and an internal combustion engine, the outlet (6) of the gasifier being connected to a fuel intake system of the engine.
- a carbonaceous solid fuel gasifier comprising a vertical vessel (4), said vessel comprising successively, from the top to the bottom: an inlet (5) of carbonaceous solid fuel ( 2) to gasify, a pyrolysis zone (10) of said fuel to produce pyrolysis gases and "char", a combustion zone (20) of the pyrolysis gases, a reduction zone (30) of the "char”, an outlet (6) of gas, and an ash harvesting area (40).
- the pyrolysis zone (10) is separated from the combustion zone (20) by active transfer means comprising a transfer lock (50) able to transfer the fuel (2) from the pyrolysis zone (10) to the zone reduction device (30) without said fuel being able to flow directly from the pyrolysis zone (10) to the reduction zone (30), thus making it possible to better control the flow rate of solid material between these two zones.
- active transfer means comprising a transfer lock (50) able to transfer the fuel (2) from the pyrolysis zone (10) to the zone reduction device (30) without said fuel being able to flow directly from the pyrolysis zone (10) to the reduction zone (30), thus making it possible to better control the flow rate of solid material between these two zones.
