Definitions

  • the invention relates to bifocals and more specifically relates to a device for adjusting combustion and re-ignition of smoke for a improved efficiency and reduced gas unburnt.
  • a chimney is said to be double hearth when it allows both to provide an open and visible fire, but also to have a closed or partially closed combustion vessel closed operating like a traditional wood stove.
  • FR-A 2 597 197 in the name of Applicant a chimney type combustion vessel, which has two levels of hearths: a closed lower hearth, closed at its upper part by two shutters likely to move relative to each other, and a focus open upper whose bottom is formed by these flaps which form the basis of this upper hearth.
  • the recipient forming the lower hearth is surrounded on the bottom and lateral sides of at least one traffic envelope air which heats up on contact with said walls container.
  • the fumes from the lower hearth must therefore circulate first along the side walls container before reaching the rear wall and exhaust duct, and this precisely to allow a good heat exchange with the air in the external envelope.
  • the Applicant endeavored to find a solution to this problem, which allows, under certain conditions to operation, a re-ignition of the fumes at the base of the exhaust duct, and consequently decrease the emission of unburnt gases and the concentration of carbon at this lower hearth.
  • the main object of the invention is therefore a device regulating combustion in a double hearth fireplace comprising a combustion chamber which can be closed, connected to a discharge pipe and delimited by a plurality of refractory plates, and whose walls outside are surrounded by an envelope intended for air circulation, said chamber being closed by at minus a removable upper wall which forms the base a second open hearth, a device according to which the wall removable upper consists of two elements separable with guide means allowing their easy spacing from one another for adjustment of the additional combustion air induction slot in the combustion chamber, and according to which an opening is provided in the bottom refractory plate for the passage direct combustion gases to the exhaust pipe in function of the introduction of combustion air between the separable elements.
  • the separable elements are sliding plates positioned on an angle iron surrounding the central opening of the hearth plate, and below its upper side, to put the hearth plate and the plates sliding at the same level as the masonry elements of the fireplace.
  • an inclined panel is provided along the orifice center of the hearth plate, on the front side of the combustion.
  • the spacing of the plates is prepositioned by grooves and a bar secured to the front plate.
  • the section of the direct passage opening of products of combustion to the exhaust pipe is about one tenth of the normal cross section of products of combustion by the sides of the appliance.
  • the container of combustion 1 has a closed enclosure 2 which constitutes the combustion chamber of the lower hearth, the face of which upper 3 is pierced with an opening closed by two separable elements which in this case are plates sliding 4 and 5. These plates form the basis of a second upper fireplace which, depending on their opening - can communicate with the lower fireplace.
  • the plates could be replaced by any tilting or interlocking system.
  • Chamber 2 is closed by side walls 6, a front wall 7 and a rear wall 8.
  • the face upper 3 is a hearth plate which integrates advantageously flush with the masonry elements 9 as is see more clearly in Figure 2.
  • a conduit 10 smoke evacuation which communicates with the bottom of the combustion chamber 2, is arranged along the wall rear 8.
  • a peripheral envelope is mounted 11 intended for the circulation of air which will heat up contact of the walls of the lower hearth.
  • This air enters the casing by a conduit 12 near the front face from the combustion vessel and emerges from it through a conduit 13 to proximity to the rear face and the opposite side.
  • sliding plates 4 and 5 are positioned on an angle iron 17 surrounding the central orifice of the hearth plate 3. These angles serving as support are below the upper face of the hearth plate. So the sliding plates are level with the hearth plate.
  • the sliding plate 5 is easily released towards the front thanks to an inclined panel 18 provided along the orifice center of the hearth plate, on the front side of the combustion, the side angles acting as slides for plate 5.
  • the angle 17 and the pan inclined 18 together constitute the means for guiding the plates (4, 5).
  • the fire develops inside enclosure 2, most of the combustion products bypassing refractory plates (14, 15) up to the exhaust duct 10. Little combustion gas passes directly from the fireplace to the conduit through the opening 16; the temperature is practically the same on both sides of the hole.
  • the chimney can also function as a chimney classic, the fire being created above the hearth plate. Alternatively, if the plates (4, 5) are ajar the chimney will work with normal draw and reverse draw to the bottom.
  • the invention provides an additional possibility for closed stove operation, taking advantage of the opening 16 provided in the refractory plate 15 for the direct passage of combustion products to the flue exhaust, and additional air induction oxidizer through the slot created between the two plates (4, 5) when we separate them from each other, to optimize the combustion as a function of the vacuum in the duct evacuation.
  • the orifice 16 For good re-ignition efficiency, the orifice 16 must not be too small in diameter, in which case it would be ineffective. It must not have too large a diameter which would cause too much direct passage of combustion gas at the expense of a good heat exchange with the air of the peripheral envelope 11.
  • the diameter of the opening represents a gas passage section of the order of 13 cm 2 .
  • the section of the lateral passages for the combustion products bypassing the side refractory plates 14 is of the order of 130 cm 2 .
  • the section of the direct passage opening 16 of the combustion products towards the evacuation duct 10 is approximately one tenth of the normal section of passage of the combustion products through the sides of the appliance.
  • the user will move the plate 5 more or less to activate the combustion and obtain a re-ignition of the fumes.
  • Such a system does not exclude operation in double hearth, i.e. a fire in bedroom 2 and a other above the hearth plate 3.
  • the plate 5 is released easily out of the hearth plate 3, for example for the loading the wood into the combustion chamber ( Figure 2).
  • the two plates 4 and 5, in position closed or ajar are at the same level as the plate hearth 3 and that the masonry elements 9 which presents a great advantage in terms of aesthetics.
