Definitions

  • the present application relates to a device that can be integrated into a chimney. More particularly, the present application relates to such a device for improving combustion within a chimney.
  • chimneys are known. Two main types of chimneys can be distinguished: closed fireplaces in which the fireplace is confined in a closed enclosure, and open fireplaces in which at least one wall of the fireplace is in contact with the open air.
  • the high temperature in the home can limit these toxic emissions.
  • the Combustion temperature is generally greater than 573 ° C, and more complete combustion occurs than in the case of an open fire, during which volatile elements harmful to the environment and health are burned.
  • the patent US 6484714 discloses a device adapted to be disposed in the hearth of a chimney comprising transfer tubes for heating the room in which the chimney is inserted (and not an improvement of the combustion of the combustion gases).
  • An object of an embodiment is to provide a device that can be integrated within a chimney and ensuring the realization of a double combustion.
  • an embodiment provides a device defining approximately a shape of L and having, in the foot of the L, at least two first nested tubes and, in the branch of the L, at least a second tube provided with at least one opening , the first tubes being arranged to define a conduit between an end of a first central tube and the at least one opening through defined passages at the ends of the first tubes.
  • the second tube comprises a plurality of lateral openings.
  • the conduit travels the entire volume of the first and second tubes.
  • the first and second tubes are circular in section.
  • the first and second tubes are made of refractory steel, stainless steel, cast iron, or a metal such as copper.
  • the first tubes define stages of the duct, the stages having an increasing section with their distance to the center of the first tubes.
  • the section of a second tube is smaller than the section of an external stage.
  • the axes of the first tubes are parallel to each other and coplanar in a plane passing through the second tube, the axis of a first tube of a first section being located above the axis of a first tube of a second section if the first section is greater than the second section.
  • the device further comprises a third tube provided with at least one additional opening, the third tube being parallel to the second tube, being located at the end of the first tubes opposite to the second tube, and extending from a first intermediate tube to form a second conduit.
  • the device comprises three first tubes.
  • An embodiment further provides an insertable block in a chimney comprising at least one device as proposed above.
  • the block comprises at least two devices as proposed above defining independent conduits, the devices being held in position by means of a frame comprising four side walls.
  • the block further comprises a removable plate capable of being positioned on the surface of the frame to close the top of the frame.
  • a wall of the armature comprises discharge openings associated with an exhaust duct.
  • the exhaust duct is defined along the armature, on the side of the second tubes.
  • the figure 1 illustrates an example of a chimney in which a block may be inserted according to one embodiment.
  • the fireplace represented in figure 1 is an open fireplace, that is to say that the fireplace is not partitioned by a closed enclosure but is created in an enclosure open at least on one of its sides.
  • combustion improving block proposed here is also adapted to be integrated into a closed fireplace or stove, to further improve the combustion of harmful volatile elements that would still be present within such a device.
  • the chimney comprises a hearth 10, also called hearth, closed by a bottom 12, side walls 14, and a horizontal floor 16.
  • the top of the chimney is partitioned by a throat 18 whose section is reduced to reach a conduit 20 smoke evacuation.
  • the floor 16 may be covered with andirons, not shown, on which are arranged fire logs.
  • a system of recovery of ash, not shown, is generally provided at the floor level of the chimney.
  • the combustion temperature of the wood is limited by the supply of fresh air on the side of the opening of the chimney.
  • the temperature above the flames can be less than 573 ° C, which allows only partial combustion: the harmful volatile elements released during the main combustion of wood (also called first combustion) are not burned.
  • a device capable of being integrated into a chimney of the type of the figure 1 , but also in a closed fireplace, allowing the realization of a double combustion within the home, this double combustion allowing the combustion of at least a portion of the harmful elements from the first combustion.
  • double combustion or after-combustion or second combustion, is meant here a combustion which is created by an intake of fresh air, the secondary air, at the level of the fumes, at a temperature sufficient for the combustion of harmful gases takes place. In practice, this temperature is greater than or equal to 573 ° C.
  • the figure 2 is a perspective view of such an insertable device within the fireplace hearth.
  • the device of the figure 2 comprises a tank 30 defining a volume in which the logs to be burned will be placed.
  • This tray 30 comprises for example four side walls.
  • the bottom of the tank 30 is delimited by a set of horizontal elements 32 acting as andirons.
  • the andirons 32 extend between the front and rear of the tank 30, that is to say they will be placed between the front and the back of the fireplace fireplace in use.
  • the andirons are constituted, as we shall see later, several tubes, for example cylindrical, nested and communicating with each other.
  • Openings 34 are defined on the front face of the receptacle 30, these openings corresponding to the end of the central tubes of each of the andirons 32.
  • Each element of greater section of each of the andirons 32 is connected to the rear of the device, that is to say in the part which will be arranged at the bottom of the hearth of the chimney, to a vertical tube 36.
  • the vertical tubes 36 comprise a set of openings 38 preferably defined laterally and on the side of the hearth.
  • the insertable block proposed here comprises a set of independent elementary structures each consisting of a chenet 32 and a vertical tube 36 held in position relative to each other.
  • the chenet 32 plays the role of a counter-current heat exchanger air-ember so that air, inserted through the opening 34, is heated using the embers formed by the logs placed on the andirons 32.
  • the heated air then passes through a means of communication between each of the andirons 32 and each of the vertical tubes 36, until reaching the openings 38 and be reinjected at the level of the fire formed in the hearth .
  • the secondary air heated within the andirons 32 and tubes 36 is returned to the top of the flames, through the openings 38, at a temperature sufficient for the mixture between this air and the gases from the flames fire present at the openings 38 at a temperature above 573 ° C.
  • the injection of secondary air via the duct formed between the openings 34 and 38 makes it possible to perform a double combustion at the openings 38, and thus to burn off the harmful gases which are released from the first combustion and who were not burned at the flames.
  • the inventors have found that it is necessary to provide at least a double passage, and preferably a triple passage, of the secondary air along the length of the andirons, a simple passage not allowing sufficient preheating of the secondary air to reduce pollution.
  • the andirons 32 are preferably arranged so that a space separates them so that ashes formed during the burning of the wood fall into an ash collection receptacle placed beneath the device (not shown).
  • the space between the andirons 32 may be between 5 and 20 mm, preferably 10 mm. Such a gap makes it possible to maintain the hot embers above the andirons 32, while allowing the evacuation of ashes down.
  • each system comprising a combination of a chenet 32 and a vertical tube 36 operates independently and defines an independent air supply duct.
  • the secondary air heated at the level of the andirons is distributed on each of the vertical tubes 36, which ensures the realization of a double combustion on a large surface of the bottom of the chimney.
  • the figure 3 is a sectional view from front to back of the device of the figure 2 .
  • the structure of the andirons 32 and their association with the vertical tubes 36 are shown in more detail.
  • the figure 4 resumes, in an isolated and enlarged way, only this association.
  • each chenet 32 consists of a set of nested tubes. In the example shown, three nested tubes are shown, but it will be noted that less than or more than three tubes may be used, preferably an odd number of tubes to facilitate the entry of air.
  • the chenet 32 comprises a first central tube 40, a second intermediate tube 42, and an outer tube 44.
  • the central tube 40 has an end located at the front of the device which corresponds with the opening 34 of the container 30.
  • lateral openings 46 are provided which allow the air from the central tube 40 to the intermediate tube 42.
  • the bottom of the central tube 40 is in this case closed.
  • the lateral openings 46 are located at the bottom of the tube 40, that is to say opposite the opening 34, so that the air circulates all along the central tube 40 before passing into the intermediate tube 42.
  • the intermediate tube 42 comprises lateral openings 48 which allow air to flow from the intermediate tube 42 to the outer tube 44. The front end of the tube 42 is in this case closed.
  • the vertical tube 36 is provided to nest in the outer tube 44 at the bottom thereof (side openings 46) so as to form a hermetic assembly.
  • openings 49 may be provided alternately either in the tube 44 or in the tube 36 to allow air to flow between these two tubes.
  • the device defines a hermetic conduit between the air inlet point 34 and the lateral openings 38 formed in the vertical tube 36.
  • the axes of the tubes 40, 42 and 44 are provided as being parallel and coplanar in a plane passing through the vertical tube 36, the axis of an outer tube being located above the axis of a tube inside. This ensures heat exchange with the brazier of good quality.
  • tubes 40, 42 and 44 are only one example, and that other assemblies allowing the realization of the same function, that is to say to define a conduit between one end of a chenet 32 and openings defined in the vertical tubes by snaking in the different tubes, may be provided.
  • tubes 40 and 42 slightly shorter than the length of the andirons 32 and held by one of their ends, so that the air flows between the tubes via the free ends of the tubes 40 and 42 (on the opposite side to the tube holding system).
  • logs are placed on the surface of the andirons 32.
  • this arrangement makes it possible to form a very hot zone on the surface of the andirons 32, which heats the air circulating in the duct formed between the inlet 34 and the outlets 38 , and firstly the air in the stage defined between the outer tube 44 and the intermediate tube 42.
  • the tubes 40, 42 and 44 define in the foxhires 32 countercurrent exchangers.
  • it operates in the andirons 32 a natural convection of air due to these heat exchanges.
  • the section of the central tube 40 (first stage) is smaller than that of the second stage (inner section of the tube 42 minus outer section of the tube 40), and that the latter is smaller than the section of the third stage (inner section of tube 44 minus outer section of tube 42).
  • This allows a relaxation between each stage, which causes a slowing of the air flow between the different tubes and allows to store a greater amount of heat energy in the heat exchange with the brazier.
  • Air compression also occurs at the inlet of the duct at the opening 34.
  • the cross section of the vertical tube will preferably be smaller than the section of the third stage so that it is created at the inlet of the tube 36 a compression and therefore a new acceleration of the air flow before coming into contact with the unburnt combustible gases to cause double combustion at the openings 38.
  • This configuration advantageously helps to improve the natural convection of air between the inlet 34 and the outlet openings 38.
  • the central tube 40 may have an internal diameter equal to 9.5 mm and a thickness of 2 mm (section of the first stage equal to 70.9 mm 2 ), the intermediate tube may have an internal diameter equal to 17.3 mm and a thickness equal to 2 mm (section of the second stage equal to 92 mm 2 ), the outer tube 44 may have an internal diameter equal to 36 mm and a thickness of 2 mm (section of the third stage equal to 661.6 mm 2 ), and the vertical tube 36 may have an internal diameter equal to 9.5 mm and a thickness of 2 mm, that is to say a section of this tube of the order 70.9 mm 2 .
  • the openings 46 defined between the first stage and the second stage may have a section equal to 84.8 mm 2
  • the openings 48 between the second stage and the third stage may have a section equal to 115.5 mm 2
  • the openings 49 between the third stage and the vertical tube may have a section equal to 70, 9 mm 2
  • the lateral openings 38 defined on the height of the tube 36 may be made by drilling, and have a diameter of between 3 and 6 mm. It will be noted that the opening 34 will advantageously be provided with the same diameter as the internal diameter of the central tube 40.
  • the outer tube 44 and the vertical tube 36 may be, to be compatible with the direct contact with the brazier, refractory steel or stainless steel.
  • the tubes 40 and 42 can also be made of steel refractory, or stainless steel.
  • the tubes mainly those in contact with the brazier, will be of a material with high temperatures and high thermal conductivity, for example cast iron or a metal such as copper.

  • FIGS 5A and 5B illustrate a practical embodiment of sleeves intended to be positioned at the front and rear of andirons 32 so as to maintain the different tubes 40, 42, 44 in position.
  • tubes 40, 42 and 44 of circular section are considered.
  • a sleeve before 50 ( Figure 5A ) is provided on the front part of the chenet 32, for example in solidarity with the receptacle 30, and a rear sleeve 52 ( Figure 5B ) is provided on the rear portion of the receptacle 30 so as to maintain the tubes 40, 42 and 44 in position.
  • the front sleeve 50 has an opening of the same diameter as the opening 34, intended to be positioned opposite the opening 34.
  • the sleeve 52 is hermetically sealed. Opposite the opening 34, the rear sleeve has a circular portion 53 in extra thickness.
  • the sleeves 50 and 52 May be provided, on the outside of the sleeves 50 and 52, an extra thickness or a sub-thickness to ensure the maintenance of the sleeves in the receptacle 30.
  • the sleeve holding elements ensure correct positioning of these, and therefore tubes 40, 42 and 44 (so as to ensure significant heat exchange with the brazier).
  • the figure 6 illustrates an alternative embodiment of the insertable block in a chimney of the figure 2 .
  • openings 60 are formed in the rear part of the receptacle 30, above the andirons 32.
  • a rear piece 62 is placed behind the openings 60 to form a duct 64 between these openings 60 and the upper part from the fireplace.
  • the structure of the openings 60 and of the part 62 allows evacuation of the fumes from the fire via the duct 64.
  • This variant is particularly advantageous in a case where it is desired to close the device of the figure 2 .
  • FIGS. 7 and 8 illustrate this state, respectively in perspective and in sectional view.
  • a removable plate 70 is placed above the brazier so as to seal the receptacle 30.
  • the smoke from the combustion are then discharged through the openings 60 to the conduit 64, and are redirected by this conduit to the duct 18 of the chimney.
  • the closing of the receptacle 30 by the plate 70 can be performed at the end of combustion, when the fire is being extinguished. This makes it possible to concentrate the heat inside a stove which would be, at that moment, with a focus almost closed by the plate 70. Other applications can then be envisaged for the chimney, for example using the plate 70 as a cooking medium for food.
  • a trap system to prevent fumes exiting through the conduit 64 are brought back into the living room.
  • conventional trap systems integrated in the chimney can be used.
  • cylindrical form of the andirons 32 and tubes 40, 42 and 44 is not limiting. Indeed, these elements may have other sections, for example rectangular, triangular, hexagonal or other, and not necessarily the same form of section between them. Indeed, only the ratio between the sections of the different elements, and the relative positioning thereof, has an influence on the effectiveness of the device.
  • the tubes 36 may be of non-circular section.
  • the number of structures comprising a chenet 32 associated with a tube 36 may vary. Indeed, we can adapt this system to fires more or less important, and more or less large areas. In the same way, it will be possible to place structures allowing the double combustion only in the center of the brazier. It will also be possible to integrate only one structure comprising an association of a chenet 32 and a vertical tube 36 in a chimney.
