Definitions

  • the present invention relates to a heating apparatus, more particularly to a solid fuel domestic heating appliance, such as wood or coal, provided with a regulation that optimizes combustion and thereby maximizes the efficiency of the appliance.
  • a wood or coal heater can operate in several gaits.
  • a maximum pace corresponding for example to P max
  • an intermediate or average pace corresponding to P max / 2
  • a minimum pace corresponding to P max / 4
  • a pace of idling corresponding to P max / 8.
  • P max is the maximum power of the appliance which, for a wood stove, is typically between 5 and 15 kW. This classification is only given by way of example to allow the following illustration of the invention and to give orders of magnitude. It goes without saying that other intermediate steps and other power criteria are possible.
  • the so-called "idle" pace for a wood stove, is typically intended for night use. At bedtime, the user reloads the stove and sets the primary air valve on the minimum position. Upon awakening, the user reloads the stove into logs and opens the flapper up to fire.
  • the losses q 1 are the highest and therefore the minimum efficiency, possibly lower than the nominal efficiency of the device, which is determined under very specific conditions.
  • the smoke temperature is the lowest and the highest efficiency, but care must be taken to stay above the dew point of the fumes (60-70 ° C), otherwise condensation occurs with accumulation of soot.
  • the technical problem to be solved, in order to optimize the performance of the apparatus independently of the pace chosen, preferably automatically, is to reduce in a controlled manner the temperature of the smoke or combustion gases, especially at high speeds.
  • Heat recovery wood stoves are also known such that the evacuation of fumes from the heating body takes place along a maximized path, by a suitable design of the evacuation duct, possibly coupled with a sheath of the type convector (see for example document BE 903 620 A ).
  • the present invention aims to overcome the disadvantages of the state of the art.
  • the object of the invention is to optimize the combustion for each heating step.
  • the invention also aims to provide security to prevent tarring in the flues, which could lead to a build-up of soot and possibly a chimney fire.
  • the invention also aims to optimize combustion irrespective of the type or the height of the chimney, as well as in the case of variable atmospheric conditions.
  • the figure 1 is a perspective view in section, right and back, of an exemplary embodiment of the regulated heating apparatus according to the present invention.
  • the figure 2 represents a right and sectional view of the device of the figure 1 .
  • the figure 3 schematically represents a perspective view of the back of the camera the figure 1 .
  • the figure 4 schematically represents a view from the right and in section of the apparatus of the figure 1 , with the smoke path shown at maximum speed.
  • the principle implemented in the invention is to reduce the smoke temperature precisely by extending the path traveled by the fumes between the combustion chamber and the entry into the chimney. Indeed, this elongation of path traveled allows greater expansion of gas and / or better heat exchange with the walls, so the cooling of fumes. According to the invention, it is desired to constantly adapt the path traveled by the fumes at different speeds of the heater, so as to optimize the performance of it, regardless of the pace adopted.
  • a heating device as shown on the figures 1 and 2 , in which the combustion chamber 1 is provided with a double wall 2A which can communicate with the combustion chamber by means of a plurality of valves, for example at least four in number of valves 11, 12, 13, 14 located at different heights h1, h2, h3 and h4, such as h1>h2>h3> h4.
  • a damper system or damper suitable for controlling the draft of a heater may be used in the context of the present invention.
  • the invention is advantageously implemented automatically by means of an open or closed loop regulation, comprising a temperature sensor (7) located in the upper part of the chimney (8, figure 3 ) and an actuator (not shown) which opens or closes the various valves above according to the value measured for the flue gas temperatures and the set temperature.
  • a temperature sensor (7) located in the upper part of the chimney (8, figure 3 ) and an actuator (not shown) which opens or closes the various valves above according to the value measured for the flue gas temperatures and the set temperature.
  • Each valve is secured to a small motor that is controlled by wire connection or radio frequency.
  • the figure 4 shows the path traveled by the fumes in the case of the maximum pace (valve 11 open).
  • the fumes escape to the atmosphere by backward passage 4 or above 4A (towards the chimney).
  • the "labyrinth" path of the fumes can be obtained by any simple means of construction known to those skilled in the art, for example by means of an "L” folded sheet revealing an orifice 2B in the lower part. stove.
  • valve 13 (14, etc.) will be open (valves 11, 12 closed) to further reduce the distance traveled by the fumes and increase the smoke temperature, and so on. If that's not enough, a direct draft damper 5 directly admitting the flue gases into the chimney, which is normally closed at other speeds, will be open at the last end, away from the dew point.
  • the "double wall" of the apparatus according to the present invention becomes a triple wall, which exchanges heat with the heating channel of the incoming air, which is also heated by the combustion chamber.
  • This sandwiching of the heating channel between two hot walls makes it possible to increase in this case the inlet temperature of the air preheated in the combustion chamber and to reduce the losses q 2 , because the combustion is improved when it is powered by preheated air.
  • the losses q 1 can also increase, which must be readjusted by means of the regulation according to the invention.
