Definitions

  • the invention relates to a combustion granulate heating device operated without auxiliary energy, which is designed to burn combustion granulate, comprising a housing with a preferably vertically oriented housing wall, comprising a filling opening provided in the housing wall, comprising a door for selectively opening or closing the filling opening with a at least in sections transparent pane element, comprising a combustion chamber arranged in the housing, comprising a storage container arranged below the combustion chamber for the fuel granules with a base and a wall on the outer side protruding from the base in the direction of the combustion chamber, and comprising a wall in the combustion chamber above the storage container and at a distance from it to these intended refractory solids.
  • a supply for primary combustion air is typically designed in such a way that primary combustion air is advantageously supplied to the combustion site.
  • the primary combustion air supply is typically adjusted by the full or partial opening or closing of individual primary air ducts by means of a manually operated selector lever - this ultimately involves the risk that the primary combustion air is not optimally supplied.
  • a generic heater is for example from EP 2 918 916 A1 famous.
  • the provision of the volume body in the combustion chamber means that the comparatively small flames that arise when the fuel granules are burned up embrace the volume body and thus appear optically expanded.
  • the flame image is perceived by an observer as larger or more voluminous with the result that it corresponds to or is approximated to the classic flame image that occurs when firewood burns.
  • An auxiliary energy-free fuel granulate heating device is also from the FR 2 995 666 A1 famous.
  • the object of the present invention is to provide an improved heating device which can be operated easily and safely.
  • the possibility of incorrect operation due to incorrect positioning of a manually operable operating lever for setting a distribution of the primary combustion air should be avoided.
  • the invention is characterized in connection with the preamble of patent claim 1 in that on the reservoir in the base and adjacent to the base on the jacket side in the wall a first group of through-openings and above the first group of through-openings adjacent to the upper Edge of the reservoir shell side in the wall, a second group of passage openings are formed.
  • a feed for the supply of the primary combustion air is formed in the heater. The supply is guided and branched out in the housing in such a way that the primary combustion air is always supplied to the first group of through-openings and the second group of through-openings at the same time. A complete interruption of the primary air supply can also be provided.
  • passage openings are then provided adjacent to the bottom of the reservoir on the shell side in the wall thereof when the shell-side passage openings are provided in a lower third of a height of the reservoir that is determined vertically when the heater is installed. Passage openings are then adjacent to within the meaning of the invention an upper edge of the reservoir provided in the shell side of the same wall if they are formed in an upper third of the wall. In a central third, the shell-side wall is designed without passage openings or is closed.
  • the reservoir is used to store the fuel granules while they are being burned.
  • the primary combustion air for burning off the fuel granules is supplied in the same way via the first group of through-openings and the second group of through-openings.
  • the first group of through-openings when the fuel granules are ignited, it is possible to supply the primary air to them advantageously from below, thereby making the course of combustion favorable.
  • the second group of passage openings provided on the shell side in the wall of the reservoir near the upper edge when the fuel granulate burns off also serves to supply primary air. In any case, it does not negatively or noticeably affect the combustion of the fuel granules in the storage container.
  • the primary air supplied via the second group of through-openings supports the post-combustion of the fuel granulate and its thermal conversion, which is as complete as possible.
  • an energetically advantageous burn-off of the fuel granules in the heater is ensured, especially since the longer the burning granules burn, ash and other combustion residues can partially or completely close the first group of passage openings, with the result that the primary combustion air ultimately flows predominantly or exclusively via the second group passes through openings into the reservoir and from there into the combustion chamber.
  • the size or number of through-openings in the second group is designed such that even when the first group of through-openings is closed, a sufficient quantity of primary combustion air is supplied for burning off/the combustion granules.
  • the heater according to the invention is particularly easy to operate and safe. In particular, incorrect operation and a malfunction of the heating device occurring as a result of the incorrect operation are effectively prevented.
  • the combustion process can be optimized at the same time through the combustion-optimized design of the reservoir and the provision of the first group of flow openings and the second group of flow openings, and the flame pattern during burning granules can be approximated to the flame pattern known from classic firewood burning.
  • the heating device according to the invention corresponds to the classic fireplaces or stoves operated with logs in terms of operation, the combustion process and the visual appearance during operation.
  • secondary combustion air can be supplied to the combustion chamber in addition to the primary combustion air. While the primary combustion air is fed into the combustion chamber from below via the storage container for the fuel granules and/or an ash container, the secondary combustion air enters the combustion chamber directly. For example, it flows into the combustion chamber from above along a glass pane (pane element) assigned to the combustion chamber.
  • the secondary combustion air can be supplied purely passively.
  • a supplied amount of the secondary combustion air can be regulated.
  • a separate flow rate modulator can be used for regulation, or the secondary combustion air can be regulated together with the amount of primary combustion air via a common flow rate modulator.
  • the heater is designed as a heater operated without auxiliary energy.
  • this is to be understood as meaning a heater in which the primary combustion air is passively sucked in or supplied during continuous operation and the fuel granules are not conveyed during operation.
  • the storage container is filled once with fuel granulate for operation.
  • a liquid or solid lighter can then be used and ignited to ignite the fuel granules.
  • Electrically operated fans for actively supplying the primary combustion air and/or discharging the air are therefore dispensed with, as are motorized auxiliary and conveying means for sequentially or continuously supplying the wood fuel, i.e. the fuel granules.
  • the electrical operation of the heater is dispensed with in the sense that neither an electrical control nor electrically actuated actuating means or the like are provided.
  • the volume body formed from a non-combustible material can, for example, be spherical, conical, truncated, pyramid-shaped, truncated-pyramid-shaped or disk-shaped.
  • a particularly favorable influencing of the flame pattern results when the volume body widens or broadens at least in sections in the direction of the flame deflection unit. This is particularly the case with spherical, conical, truncated cone, pyramid and truncated pyramid shapes.
  • the volume body can also be designed as a disc body or baffle plate and thus promote turbulence of the combustion gases and optically enlarge the flames. Other shapes are also conceivable, as long as their geometry makes them suitable for the flame to embrace and thus optically widen the flame.
  • the volume body can be formed from a metallic material or from a mineral material, for example. In particular, it can be positioned hanging in the combustion chamber.
  • the volume body can be wall-mounted by means of a holding device or supported by a support pillar.
  • a holder for a chain, a rod, a rope or another attachment means can be provided, in particular in the area of a lower deflection plate of the flame deflection unit.
  • the fuel granulate heating device according to the invention can be designed, for example, in the manner of a wood-burning stove or a chimney or an outdoor chimney.
  • the heat generated by the heater can be used to heat and/or fire an oven and/or roast or bake and/or grill or the like.
  • the supply for the primary combustion air provides a manually or passively operable flow rate modulator.
  • the flow quantity modulator is designed in such a way that the quantity of the primary air supplied to the first group of flow openings and to the second group of flow openings can be adjusted continuously or in stages at the same time.
  • the flow rate modulator it can succeed in this respect, the amount of primary supply air and thus in particular to control and optimize the combustion process.
  • the flow rate modulator can have a manually operable pivoting lever for adjusting the air volume.
  • the actuation of the flow rate modulator can, for example, be designed in such a way that there are two preferred positions for the flow rate modulator due to a local tightness in the pivoting area or a detent-like shape.
  • the primary air supply for the burning process is optimally designed.
  • there is an optimal primary air supply for continuous operation which is advantageously selected in particular with regard to the emission values or other firing values.
  • the actuation of the flow rate modulator has no influence on the always equally regulated or distributed supply of the primary combustion air to the first group of through-openings and the second group of through-openings.
  • the flow rate modulator is not a selector lever for changing the air flow.
  • a temperature-sensitive switch in particular a bimetal switch, can be provided for passive actuation of the flow rate modulator.
  • the reservoir for the fuel granules is covered by a screen with at least one passage through which the flames or fuel gases are conducted into the combustion chamber.
  • the through-hole can extend horizontally or vertically and can be used to optimize combustion or to influence the flame pattern.
  • secondary air can be prevented from entering the reservoir.
  • the screen can be disk-shaped or ring-shaped, with the passage opening being provided in the plane of the screen.
  • the screen can have two horizontally spaced discs between which the through-hole extends vertically and/or in the form of a ring or ring segment.
  • the cover placed on the storage container serves to further adapt the flame pattern during burning of fuel granules to the classic flame pattern of firewood burning.
  • the fact is that by providing the screen with the through-hole, the combustion gases or the flames reach the combustion chamber in a locally concentrated manner and, to that extent, a larger flame above the through-hole is formed, which also appears optically enlarged when gripping around the volume body.
  • the splitting of the flames promotes the reaction of the combustion gases with the oxygen provided in the combustion chamber.
  • an improved thermal conversion or a particularly high thermal efficiency can result for the heating device according to the invention.
  • the emission during operation of the heater which is already particularly favorable due to the optimized primary air supply, can be additionally improved in this respect.
  • the reservoir for the granular fuel can be designed to be removable. This simplifies the filling of the reservoir with the fuel granules and the cleaning of the reservoir after combustion.
