Definitions

  • the invention relates to a heating device such as stove, fireplace, stove, central heating boiler, oven, dryer and others, for the combustion of solid fuels in closed and open spaces.
  • the main object of the invention is the production of a heating device which allows perfect control of the fire with a very high combustion temperature and a high yield, regardless of the species of solid fuel used.
  • Another object is that the fireproof glass which is in a door for closing, for example, a fireplace or a stove, is kept free of soot, tar and condensation. Yet another goal is to achieve a long life grid.
  • CH-A-261310 Also known from CH-A-261310 is a grid which consists of an upper grid and a lower grid which can be slid relative to each other in order to adjust the size of the passage openings of the wire rack.
  • the slit width between the grid bars over their entire length remains equal, so that this grid has the same drawback as that described in NL-A-29877.
  • no accessory device is provided for the supply of secondary air.
  • DE-C-936230 also discloses a grid made up of two grid parts which can be slid in a rectilinear manner with respect to each other, the width of the slot between the grid bars remains equal over their entire length, whatever or the position that the grids take in relation to each other, so that this grid also has the same drawback as the grids described in the abovementioned Dutch and Swiss patents.
  • this disadvantage is even greater because when the upper grid is rotated, on which occasion the slots of the upper and lower grids happen to overlap, the width of the slot is greatest against the periphery of the grid at the center of your gritte center. here not worse, there is no accessory device provided for the supply of secondary air.
  • the heating device according to the invention and described in the first characteristic part of claim 1 has the advantage that the center of the fire can receive more primary air than its periphery. This allows better fuel combustion for all fire capacities, depending on the position of the movable grate relative to the fixed grate. This is achieved by gradually closing the ends of the passage openings which are located at the periphery of the grids.
  • An additional advantage is that where there is the most fire on the grate and where the most air is brought in, this place is the most cooled, thanks to which the life of the grate is considerably extended.
  • Another advantage of the special construction of the heater according to the invention is the supply of secondary air through the opening, which opens vertically into the combustion space provided under the glass door. In addition, a perfectly clean air curtain is formed against the glass door, which keeps it perfectly clean. Another advantage is that air pollution by carbon monoxide is reduced and the volume of ash is reduced to a minimum.
  • openings passage 6-10 in the two grids 5-7 should also be able to have other forms and can be in the form of small holes, oval, round openings or in other forms, placed in a triangle, provided that it is ensured that the passage of each passage opening 10 formed in the grid 7 is greater in the center of this grid.
  • this grid could be provided in the center with openings which are larger than those provided near the lateral sides of the grid, or else one could provide in the center of the grid with more openings than near the lateral edges of this one.
  • This grid 7 is provided at the front with a lever 11, which can be actuated on the front of the open hearth to move said grid 7 relative to the grid 5. The passage of air is maximum when the passage openings 6 -10 of the two grids 5-7 are just superimposed.
  • each passage opening has the shape of a triangle.
  • the central part of the grate then receives more air than the lateral sides, so that the combustion of the fuel on the grate is most intense in the center of the fuel. An effective air adjustment is therefore possible depending on the size of the fire you want to obtain.
