Definitions

  • the invention relates to a high efficiency closed hearth, in particular for chimneys of apartments or individual houses, and, in particular, of the flame vision type.
  • the improvement applied to high efficiency closed fireplaces according to the invention relates more precisely to a combination of means making it possible to improve the combustion and the thermal efficiency of such devices.
  • the closed hearth is produced with double walls between which circulates a first stream of recovery air intended to carry and to eject by evacuation openings provided on the front face the calories radiated by the walls of the hearth.
  • the second recovery air flow passes through the volume delimited by the exterior walls and the chimney wall.
  • Another way of improving the thermal efficiency and the power of such devices is to promote combustion by an appropriate arrangement, arrangement or configuration of technical elements or forms.
  • the general idea of the invention consists in providing means for increasing the path of the smoke and hot combustion gases inside the appliance, and in particular in the upper part, while keeping an effective draft adjustable progressively and individually between a minimum value (slow-motion fire) and a maximum value (high fire), this in combination with an admission of air uniformly diffused in the upper and lower parts, by linear ramps or vents to which one can add, but not necessarily, a or two diffuse ramps side zion.
  • Figure 1 is a schematic view in open perspective of the improved closed hearth according to the invention.
  • Figure 2 is a schematic cross-sectional view of the closed fireplace hearth improved according to the invention.
  • Figure 3 is a schematic detail view in perspective of the upper part of the closed hearth improved according to the invention.
  • Figure 4 is a schematic view in vertical section parallel to a front plane of the upper part of the closed hearth improved according to the invention along the line IV-IV of Figure 2 in the open direct discharge valve position.
  • Figure 5 is a schematic detail view in longitudinal vertical section of the upper part of a preferred variant of the improved fireplace according to the invention in the open direct discharge valve position.
  • the improvement according to the invention relates to a combination of means making it possible to appreciably improve the thermal efficiency of closed hearths in particular for fireplaces without bringing additional constraints in the maintenance of these devices.
  • This compartment communicates in the lower part with the hearth 2 by a passage 6, for example rectangular, delimited by the walls of the hearth and the lower edge of the plate 3 of shorter length than the height of the hearth.
  • This deflection plate 3 is entirely removable. It can be pivotally mounted around an upper articulation axis 7 or movable vertically by translation along slides 8 or racks 9.
  • This deflection plate can be coordinated with the movements of the valve 10 for direct evacuation of the fumes by a mechanical connection 11 so that at a determined position of the valve 10 corresponds to an inclination or a vertical level of said plate, thus achieving the optimal distribution of discharge rates.
  • Reverse combustion consists in bringing the combustion air in the opposite direction, that is to say from the top to the bottom. It provides many benefits from improved thermal efficiency through more complete and cleaner combustion.
  • the improvement according to the invention requires a particular diffusion of the combustion air and this as soon as it enters the hearth.
  • the profile constituting the frame can be drilled on its rear face of intake orifices such as 17 with fixed or adjustable flow in linear arrangement on its crosspieces 12 but also on its uprights 13 thus forming as many linear diffusion ramps 18 directed towards the foyer.
  • the air will be admitted by means of a damper 19, for example sliding or with tubes coaxial 20, provided for example in the lower part of the access door.
  • a first distribution is planned during construction in the choice of the ratio between the surfaces of the high and low openings.
  • Maintaining a combustion air supply in the lower part is essential for starting the fire, which necessarily requires a large draft.
  • the arrows show by way of illustration an example of distribution of the air and hot gas currents in the hearth. We note that we favor the evacuation by the exchange compartment 5.
  • the draft When switching on and during the heat-up phase, the draft will be adjusted to its maximum value by acting not only on the air inlets, but also on the control of the direct smoke evacuation valve 10.
  • the valve for direct smoke evacuation is completely closed, the upper air inlets of the upper ramp 18 are opened to the maximum.
  • the combustion air arriving from the upper ramp 18 will create along the rear face of the window or the access door a protective curtain which will prevent the deposition of dirt and will maintain this surface in a satisfactory state of cleanliness.
  • the air intake comes from the chimney through the lower passage 6 located in a position opposite the upper air inlet.
  • the combustion air flow crosses the ignited wood from top to bottom at an adjustable rate through the air inlets and the section of the lower passage 6.
  • a secondary operating mode relates to the door open operation in which the door and the direct evacuation valve are open. In this operating mode, combustion is maximum.
  • the control of the direct evacuation valve is subject to the door so as to guarantee its total opening as soon as the door reaches a degree of opening deemed dangerous.
  • the compartment 5 is extended upwards by the smoke box formed by two horizontal channels 23 and 24 delimited by the side walls of the interior 2 jacketed interior 25 and two vertical blades 26 and 27 arranged on either side of the duct smoke evacuation 28.
  • the blades 26 and 27 are made of length less than that of the hearth so as to form a slight shrinkage 29 at the front wall to allow the flue gases and combustion gases having traveled along the channels 23 and 24 to join the central evacuation volume 30 delimited by the blades 26 and 27 and the upper horizontal walls 31 and 32 of the foyer.
  • the exhaust volume 30 is completely closed at its rear part to avoid semi-direct communication of the fumes with the exhaust duct 28, the normal inlet of the fumes being constituted by the withdrawal 29 and the front wall. full adjacent.
  • the evacuation compartment 30 communicates with the base 33 of the flue 28 passing through the upper ejection volume 34 of the hot air at the front wall.
  • This ejection volume is produced in this case entirely open on its front face, as can be seen in FIGS. 1 and 3.
  • the base 33 of the flue pipe 28 faces exactly or offset the outlet for direct smoke evacuation so as to create the maximum air draw in the open position.
  • this technical configuration makes it possible to recover a significant amount of calories normally lost because carried away by the fumes.
  • the smoke path is increased by at least one hearth length and the exchange surfaces are found to be significantly larger.
