  • the closure member can be part of the configuration of the concentric connection duct as soon as it is installed (for example it can be installed in a straight part of the duct by being integrated into a part which itself forms a section of this duct) and be actuated or implemented when needed.
  • a connection duct is understood as being the part of the duct which is located between the generator of combustion products and the vertical duct, generally called the collective duct.
  • the vertical flue can be a concentric flue (double flue) which includes a central flue for the evacuation of the combustion products and a peripheral flue for the fuel supply or a simple flue which is used only for the evacuation combustion products.

  • a heating and/or domestic hot water production installation comprises several generators of combustion products, in this case boilers, two of which only are illustrated under the references 12 and 14.
  • the number of generators of combustion products is generally higher in a collective installation of a building such as an apartment building.
  • Each of the boilers 12 and 14 is connected to a vertical concentric conduit 19 which extends inside the building passing through the various rooms where the boilers of the installation are located and, for this purpose, crosses the partition wall. 16 and the roof portion 18 to emerge outside the building.
  • the vertical pipe can serve a greater number of premises and include a greater number of boilers (generators of combustion or reaction products).
  • Each boiler is connected to the vertical duct 19 via a concentric connection duct which is specific to each boiler, namely the duct 20 for the boiler 12 and the duct 22 for the boiler 14.
  • Each concentric connection duct corresponds generally to the pipe part of the collective installation which is located between one of the boilers and the collective vertical pipe.
  • Each concentric duct that is to say the vertical concentric duct 19 and each of the concentric connecting ducts 20 and 22, here comprises a central duct for discharging the boiler combustion products and a peripheral duct for supplying oxidant , here air, boiler.
  • the oxidant circulates in the peripheral duct against the current of the combustion products in the central evacuation duct.
  • the peripheral duct 19a of the vertical concentric duct 19 takes the oxidant (air) outside the building and conveys it to the various peripheral ducts 20a, 22a of the connection ducts 20, 22 to supply it to the respective boilers 12 and 14 for the feeding them with oxidizer.
  • the central duct 19b of the vertical concentric duct 19 collects the combustion products coming from the various central ducts 20b, 22b of the connecting ducts 20, 22 and conveys them outside the building above the roof of the latter.
  • the vertical duct does not necessarily have a concentric configuration but it necessarily comprises a vertical duct for the evacuation of the combustion products.
  • each concentric connection duct 20, 22, more particularly on the central conduit 20b, 22b of the latter one or more shutter members, in this case only one member is used, to locally shut off the central conduit (the shutter is carried out locally, at the place where the obturation member is positioned) without blocking the peripheral duct.
  • the circulation of the oxidant in the peripheral duct is therefore not disturbed, or in any case is not interrupted, by the closure member, which allows the oxidant to form an envelope or insulating sheath circulating around the central duct. and therefore providing additional protection by confining the products of combustion inside this envelope/sheath.
  • the closing devices are not represented on the figure 1 for the sake of simplicity. They are however shown in the following figures in the form of different possible embodiments.
  • Each concentric connecting duct forms an opening for inserting said closure member inside the central duct.
  • This opening is distinct from the inlet and outlet orifices of the central duct through which the combustion products circulate.
  • the opening opens on one side inside the central duct and on the other side on an outer wall of the concentric connection duct.
  • the opening opens onto the outside of the concentric connection duct. The opening thus allows access to the central duct.
  • An operator can insert the obturation member through the opening to allow the obstruction of the central duct.
  • the opening can also lead to the peripheral duct.
  • the opening also allows access to the peripheral duct. An operator can thus carry out a maintenance operation or a verification of the peripheral duct.
  • the shutter member or one of the shutter members is configured to obstruct the opening at the level of the peripheral conduit. This obstruction of the peripheral duct prevents air from escaping from the peripheral duct via the opening.
  • Said at least one closure member is preferably designed to be removable, in particular through said opening.
  • the term “removable” means that the closure member can be extracted from the opening. The removability is compatible with the possibility of locking the closure member when it is in one or more operating positions.
  • shutter members can be used to perform the function of local shutter of the central duct. It is in fact possible to use a first closure member intended to be inserted through an opening opening into the central duct. This first closure member is capable of obstructing the central duct when it is inserted inside this opening. A second closure member can then be used to obstruct the opening emerging into the central duct without obstructing the central duct itself.
  • the first closure member makes it possible to carry out maintenance operations on the installation or to condemn a central duct by preventing the combustion products from circulating through the central duct.
  • the second shutter member is used in normal operation of the combustion product generator by obstructing the opening allowing the insertion of the first shutter member while allowing the circulation of the combustion products through the central duct.
  • the closure member can also be made in several parts.
  • a first part can be configured to obstruct only the opening at the level of the peripheral duct while leaving the opening at the level of the central duct free.
  • a second part can be configured to obstruct the opening at the central duct as well as the central duct itself for the function of obstructing the products of combustion.
  • the first and second parts can be configured to interlock or connect together.
  • each closure member is capable of occupying, in the central duct, a first position, called open, in which the passage of combustion products is authorized and a second position, called closed, in which the passage of products combustion chamber is clogged.
  • the passage from one position to another is made possible in a particularly simple manner thanks to the presence of an actuating part or implementation of the closure member which is arranged outside the concentric duct connection (in a suitable place, generally easily accessible from the outside) and which can therefore be handled/operated from outside this duct by an operator.
  • the closing of the central connection duct can therefore be carried out in a particularly simple manner, when a maintenance operation must take place, without having to dismantle this duct.
  • Said at least one closure member is configured to obstruct said opening when it occupies the first and second positions in the central duct. Thus, no combustion products escape through this opening when combustion products are generated. Said at least one closure member therefore forms a plug for this opening in addition to its function of closing the central duct.
  • the first and second positions can be achieved by different shutter members.
  • the insertion of the second closure member corresponds to the first position, called open, in which the passage of the combustion products is authorized.
  • the insertion of the first closure member corresponds to the second position, called closed, in which the passage of the combustion products is obstructed.
  • Said at least one closure member is preferably capable of occupying a third assembly/removal position in which the closure member is free to be inserted into or removed from the opening.
  • This third position is distinct from the first and second positions.
  • the installation may further comprise at least one device for detecting the presence or the position of said at least one closure member in the central duct.
  • said at least one detection device can detect whether the closure member is placed in the opening and/or its position in this same opening.
  • said at least one detection device is configured to detect when said at least one shutter member is in the first and/or in the second position and/or in the third position, as the case may be.
  • Said at least one detection device is configured to transmit to at least one control member of the installation information representative of the presence and/or of the position of said at least one shutter member in the opening.
  • the control member can be internal to a generator of combustion products or external to the latter.
  • the control member can also be collective, i.e. in charge of controlling a plurality of combustion generators.
  • the control of the generator of combustible products can thus be carried out according to this information.
  • the start-up of the fuel product generator arranged upstream of the concentric connection duct may be subject to the presence and the correct position of the closure member therein, for example the first position.
  • starting up the fuel product generator can be made impossible if the closure member is absent or in a maintenance or intermediate position.
  • the information relating to the presence and/or to the position of said at least closure member can be transmitted to several fuel product generators in order to control their operation.
  • Said at least one detection device may comprise an end-of-travel detector configured to detect whether said shutter member is in a predetermined position.
  • Said at least one detection device may comprise a plurality of end-of-travel detectors, for example two, to determine several positions of the shutter member. Position detection can be performed via a contact, for example with a contactor brought into contact with the shutter member, or without contact.
  • the installation can also provide a locking system for the shutter member.
  • This locking system may provide for locking the arrangement of the shutter member inside the opening for security reasons. In this case, the shutter member can still move from the first position to the second position and vice versa. However, the extraction of the shutter member from the opening is prohibited by the locking means.
  • the deactivation of the locking means can for example make it possible to move the closure member into the third position in order to be able to be extracted from the opening.
  • the locking means can for example be deactivated by a tool or even a control signal authorizing the extraction of the closure member.
  • the shutter member can also provide a visual position indicator.
  • a visual indicator may be provided to determine in which position among the first, second and third positions the closure member is located.
  • This visual indicator is for example luminous, colored, a shape or even a relief.
  • the shutter member(s) of the concentric boiler connection ducts can be positioned at different places on the duct and can, for example, be different from one connection duct to another.
  • connection ducts all have the same geometrical arrangement since, on the one hand, they each comprise a part forming an elbow or a T connection to the boiler 20c, 22c which is here connected to the top wall of the boiler and extends vertically and obliquely and, on the other hand, they each extend by a horizontal rectilinear section 20d, 22d which is connected to the vertical conduit 19.

  • the portion 50a has, at one of its two opposite ends, an end face 50a3 closing the hollow cylindrical space of said portion (the cylindrical space is open at the opposite end of the portion 50a which faces the remaining portion of the connecting duct) and on which is mounted a part or actuating element 62 which remains accessible to an operator from outside the connecting duct, regardless of the position of the closure member.
  • part 62 is connected to end face 50a3 via a rod 64.
  • the portion 50 forms together with the actuating part 62 and its rod 64 a device of the piston type.
  • sealing gasket devices 66 and 68 are respectively provided at the two opposite ends of the portion 50a in order to ensure sealing with the inner face of the conduit portion 58 in which it slides.
  • an annular seal is provided at the outer edge of the opening 50a1, in cooperation with the internal face of the conduit portion 58.
  • An opening 53 is formed in the part 52 to allow the insertion and/or the withdrawal of the shutter member 50.
  • This opening 33 opens inside the horizontal duct portion 58.
  • the opening 33 is arranged at the intersection between the horizontal 58 and vertical 60 duct portions.
  • the opening 53 is here aligned with the horizontal duct portion 58.
  • the opening 53 is separate from the inlet 55 and outlet orifices 57 combustible products.
  • the opening 53 here formed by an open end of the T-shaped piece 52.
  • a third embodiment of a shutter member 80 is illustrated in the figures 4A-B .
  • the member 80 is placed in a rectilinear part 82 of a connecting duct such as one of those illustrated on the figure 1 , for example part of a horizontal conduit 20d or 22d.
  • the duct part can be vertical or adopt a different configuration insofar as it is a rectilinear part or section of a concentric connecting duct.
  • the rectilinear part 82 of the concentric connection duct comprises a peripheral duct part 82a conveying the oxidant and a central duct part 82b conveying, in the opposite direction, the combustion products from the boiler.
  • the boiler is connected directly or indirectly to the left of the straight part 82.
  • the shutter member 80 is arranged inside the central duct part 82b and is rotatably mounted around an axis or control rod or actuation 84 which passes through the two walls of the two conduit parts 82a and 82b respectively in sealed manner.
  • the axis of rotation is perpendicular to the rectilinear part of the duct.
  • An actuating part or element 86 accessible from the outside of the rectilinear part 82 (this part is generally arranged adjacent to this rectilinear part and, for example, along it) is connected to the axis of rotation 84 to cause its rotation, therefore that of the closure member 80, and thus the change of position of this closure member between the open position of the figure 4A (the combustion products generated by the boiler can be freely evacuated through the central duct part, while the oxidant circulates in counter-current in the peripheral duct part) and the closed position of the figure 4B (the combustion products are blocked by the shutter member, while the oxidizer still circulates against the current in the peripheral duct part).
  • the shutter member 80 has the general shape of a disk which, when it is positioned parallel to the axis of the central conduit part (more precisely, parallel to a vertical plane which is here the plane of the figure and which contains the axis of the central duct part), allows the products of combustion to pass freely and, when positioned perpendicular to this axis, after a rotation of 90°, opposes the passage of combustion products.
  • the control shaft 84 passes through the disc in its thickness and extends along a diameter of the disc, in the middle thereof. Seals can be arranged around the disk or on the internal wall of the central duct, at the place where the disk comes to rest.
  • the maneuvering piece 86 can adopt different shapes such as, for example, that of a butterfly valve handle.
  • the closure member 90 is engaged inside a second portion of the central duct of the T-shaped or elbow-shaped part (the second portion corresponds for example to the second portion 38 of the figure 2A or to portion 58 of the Figure 3A ) and has a free emerging end 90a which is bevelled. More particularly, this bevelled end 90a is arranged at the intersection between the two portions of central duct 38, 40 of the part which are mutually perpendicular so as to give a general T shape, as in the figures described above.
  • the two intersecting portions 38, 40 could adopt different geometric orientations with respect to each other, as already described above.
  • the shutter member 90 thus configured in this variant is capable of being moved in rotation around its longitudinal axis which extends inside the second portion 38 of central duct mentioned above so that, in a first position ( fig. 5A ), the beveled emerging end 90a is positioned angularly so as to be oriented opposite the first portion 40 and the second portion 38 of the central duct to place the two portions in communication with each other and allow the evacuation combustion products.
  • the shutter member 90 can be moved into a second position ( fig. 5B ) in which its beveled emerging end 90a is oriented opposite to the first portion 40 in order to present vis-à-vis the latter the non-bevelled zone of the emerging end and therefore to obstruct the intersection and thus passage of combustion products.
  • the oxidant can always circulate freely in the peripheral duct of the connecting duct.
  • an external actuating part or element 42 is arranged to move the shutter member 90 from one position to another.
  • An opening 93 is formed to allow the insertion and/or the withdrawal of the closure member 90.
  • This opening 93 opens inside the second portion 38.
  • the opening 93 is arranged at the level of the intersection between the first 40 and second 38 servings. In particular, the opening 93 is here aligned with the second conduit portion 38.
  • the opening 93 is separate from the inlet 95 and outlet 97 orifices of the combustible products.
  • the opening 93 here formed by an open end of the T-shaped or elbow-shaped part.
  • the figure 6 illustrates another embodiment of an installation 100 according to the invention in which the vertical duct does not have a concentric dual-flow configuration: it is a single collective vertical duct 102 which is used to evacuate the products of combustion (here the combustion gases from boilers 104 and 106) and which, for this, is connected to concentric connecting ducts such as ducts 108 and 110. It will be noted that in practice the collective vertical duct can be arranged inside another duct or plug, not shown here .
  • Each concentric connecting duct 108,110 comprises a peripheral duct 108a, 110a surrounding a central duct 108b, 110b which is directly connected to the vertical collective duct 102 for the evacuation of combustion products from the boilers.
  • each concentric connection conduit is not connected to a peripheral vertical conduit for supplying oxidizer (eg air) which surrounds the vertical collective conduit for the evacuation of combustion products.
  • oxidizer eg air
  • the peripheral duct 108a, 110a of each concentric connection duct 108,110 is directly connected to an air supply which can be either the ambient air of the room or the air outside the room and, for example, the air outside the building (via a feed pipe not shown in the figure).
  • one or more peripheral air inlets E1, E2 are arranged directly at the level of the wall of the peripheral duct concerned and the supply air is illustrated by arrows pointing to the air inlet(s).
  • the air inlet(s) of each peripheral duct are arranged as close as possible to the collective vertical duct 102.
