Definitions

  • the invention relates to a fuel-free operated fuel granulate heater, which is designed for combustion of fuel granules, comprising a housing with a preferably vertically oriented housing wall, comprising a provided in the housing wall filling opening comprising a door for selectively releasing or closing the filling with a section at least transparent disc element, comprising a combustion chamber arranged in the housing, comprising a reservoir arranged below the combustion chamber for the fuel granules having a bottom and a peripheral side projecting from the bottom in the direction of the combustion chamber, shell side wall, and comprising one in the combustion chamber above the reservoir and spaced to the very same refractory solid.
  • a supply of primary combustion air is designed so that in each case advantageously primary combustion air is supplied to the place of combustion.
  • the adaptation of the supply of the primary combustion air is typically carried out by the complete or partial release or closing of individual primary air ducts by means of a manually operated selector lever - this ultimately entails the risk that the primary combustion air is not supplied optimally.
  • a generic heater is for example from the EP 2 918 916 A1 known.
  • the comparatively small flames which are produced during combustion of the fuel granules embrace the volume body and thus appear visually expanded.
  • the flame image is perceived by a viewer larger or more voluminous so with the result that it corresponds to the classic, occurring in the combustion of firewood flames or is approximated.
  • Object of the present invention is to provide an improved heater, which can be operated in a simple manner and operated safely.
  • the possibility of incorrect operation by incorrect positioning of a manually operable control lever for setting a distribution of the primary combustion air should be avoided.
  • the invention in connection with the preamble of claim 1, characterized in that on the reservoir in the bottom or adjacent to the bottom shell side in the wall, a first group of passage openings and above the first group of passage openings adjacent to the upper Edge of the reservoir shell side in the wall, a second group of passage openings are formed.
  • a supply for the supply of the primary combustion air is formed in the heater. The supply is guided and branched in the housing so that the primary combustion air is always supplied simultaneously to the first group of passage openings and the second group of passage openings. A complete interruption of the primary air supply may also be provided.
  • passage openings are then provided adjacent to the bottom of the reservoir shell side in the wall thereof, when the shell-side passage openings are provided in a lower third of a vertically determined in the installation state of the heater height of the reservoir. Passage openings are then adjacent to within the meaning of the invention an upper edge of the reservoir shell side provided in the wall thereof when they are formed in an upper third of the wall.

In any case, it does not negatively or appreciably affect the burnup of the fuel granules in the storage container.
  • the primary air supplied via the second group of passage openings assists the afterburning of the fuel pellets and their as complete as possible thermal conversion.
  • an energetically advantageous burn-up of the fuel granules in the heater is ensured, especially as the firing period of the fuel granules ash and other combustion residues partially or completely close the first group of passage openings, with the result that the primary combustion air finally predominantly or exclusively via the second group from passage openings in the reservoir and from there into the combustion chamber.

  • the diaphragm may have two horizontally spaced discs, between which the passage recess extends vertically and / or annularly or annular segment-shaped.
  • the patch placed on the reservoir aperture serves insofar as to adapt the flame pattern during combustion granules burn-on to the classic flame pattern of logs burn-off. It is such that by providing the diaphragm with the passage recess, the fuel gases or the flames locally concentrated get into the combustion chamber and thus a larger flame above the passage is formed, which additionally appears optically enlarged when grasping the volume body. At the same time, the reaction of the fuel gases with the oxygen provided in the combustion chamber is promoted by splitting the flames. In this respect, an improved thermal conversion or a particularly high thermal efficiency for the heater according to the invention can result.
