  • a generic heater which is designed for the preparation of hot water, is from the EP 0 064 456 A1 known. It is hereby a closed, continuously operated system disclosed with active air supply and a needs-based, actuated actuated supply of granular fuel.
  • a heater which is designed for the thermal utilization of granular fuel.
  • the heater has, as described above, an active supply air arrangement and a motor system for demand-based or continuous supply of the granular fuel in the storage chamber.
  • the system dispenses with a stovepipe and therefore also on a baffle plate, which is to prevent the entry of flames into the stovepipe.
  • the object of the present invention is to make a granular fuel-powered heater constructive so that the formation of large-volume flames favors and the flame pattern is approached during operation of the heater with the granular fuel to the classic flame image of a piece-fired heater.
  • the invention has the features of claim 1.
  • the particular advantage of the invention is that the volume body is encompassed by the flames.
  • the volume body splits the flames and increases their volume with the consequence that in the perception of an observer, the flames increase optically.
  • the flame image resembles a classic general cargo flame.
  • the solid formed from a non-combustible material may for example be spherical, conical, frusto-conical, pyramidal, truncated pyramidal or disk-shaped.
  • a particularly favorable influence of the flame image results when the volume body at least partially widens or widened in the direction of the flame deflection unit. This is especially the case of the spherical, conical, truncated cone, pyramid and truncated pyramid.
  • the solid can continue to be designed as a disk body or baffle plate and thus favor a turbulence of the fuel gases and visually increase the flames.
  • the solid can be formed for example of a metallic material or of a mineral material.
  • it can be positioned suspended in the flame chamber.
  • the volume body can be provided by means of a holding device wall-mounted or be supported by a buttress.
  • a receptacle for a chain or other fastening means can be provided, in particular in the region of a lower deflecting plate of the flame deflecting unit.
  • the granular fuel storage chamber is removable.
  • the heater can then be fired either with the granular fuel or with general cargo.
  • a grate or another support for the piece goods can be inserted.
  • the volume may either remain in the flame chamber or the volume may be removed from the flame chamber.
  • the volume is designed removable.
  • the solid is removed from the flame chamber with the chain, pillar, or other fastener.
  • An inventive heater according to the FIGS. 1 to 4 comprises as essential components a flame chamber 1, which is surrounded on the shell side by a wall 2, a storage chamber 3 for a granular kiln, a Flammenumlenkong 4 and a solid body 5 made of a non-combustible material.
  • the solid 5 is suspended in the flame chamber 1.
  • a chain 6 is provided, which is fixed to the end of the volume body 5 on the one hand and a baffle plate 7 of the flame deflecting unit 4 on the other.
  • the flame chamber 1 is further associated with a door 8 with a disc surface 9. Through the disc surface 9, a flame image can be considered during operation of the heater.
  • the heater can be operated for example with wood pellets as a granular fuel.
  • the wood pellets are filled into the storage chamber 3 provided below the flame chamber 1 and set on fire by means of a lighter.
  • a horizontal distance 10 between an upper edge 11 of the storage chamber 3 and the volume body 5 is selected so that the flames surround the volume body 5 or are split on the volume body 5.
  • the volume body 5 is a flow obstacle or a resistance for the fuel gases there, which causes turbulence in the flame chamber 1 leads.
  • the thermal utilization and conversion of the combustible is therefore above average and combustion takes place with low emissions.
  • the wall 2 of the flame chamber 1, as well as the lower baffle plate 7 at least partially from temperature-resistant fireclay bricks.
  • the combustion gases escaping from the flame chamber 1 via the flame reversal unit 4 are discharged via a furnace tube 12. Adjacent to the Flammenumlatician 4 in this case a furnace tube 12 encompassing heat storage 13 is provided, which is heated by the existing heat in the exhaust gases and the stored heat gives a time delay to the combustion process.
  • a supply of oxygen into the flame chamber 1 or the storage chamber 3 takes place for example via a supply air duct 14.
  • a controller may be provided for influencing a volumetric flow of the oxygen.
  • an ash container 15 is provided at the furnace below the storage chamber 3.
  • the ash container 15 serves to receive residual ash resulting from the combustion process.
  • a second inventive heater according to the Figures 5 and 6 has essentially the same components essential to the invention.
  • the volume body 5 is provided suspended in the flame chamber 1.
  • the storage chamber for the granular fuel and the ash container 15 are provided below the flame chamber 1.
  • the solid 5 is spherical as before and spaced from the wall 2 of the flame chamber 1 and provided in the door 8 disc surface 9 is provided.
  • the heater has a particular circular cross-sectional shape. It is dispensed in the illustrated embodiment, a heat storage in the region of the furnace tube 12. Optionally, such a heat accumulator can be attached to the heater.
  • a third inventive heater according to the FIGS. 7 and 8th provides a fixed to a fixture 16 solid 5 before.
  • the holding device 16 is L-shaped.
  • a holding arm 17 extends substantially horizontally and is connected at the end to the volume body 5.
  • a support arm 18 extends substantially vertically. The support arm 18 is fixed to the support arm 17 and supported on a surface of the flame chamber 1.
  • the geometry of the heater can be designed variable.
  • any cross-sectional geometry can be used.
  • the provision of a heat accumulator is optionally possible in each embodiment.
  • the heater can be designed in each case as combi unit for the combustion of fuel granules and general cargo or as a pure granular heater.
  • FIGS. 9 to 16 show various embodiments of the bulk body 5 and an assignment thereof to the storage chamber. 3
  • the volume body 5 is spherical.
  • the storage chamber 3 has a circular opening 19 facing the volume body 5 and a substantially cylindrical, stepped running surface 20.
  • a collar 21 is formed on the volume body on the shell side, and a collar 22 in the region of the shell 21 on the shell side.
  • the collar 22 serves to apply the storage chamber 3 to a bottom 23 of the flame chamber.
  • the storage chamber 3 is designed removable.
  • the collar 22 is located on the bottom 23 of the flame chamber 1 and is supported on this.
  • two handles 24 are also provided.
  • the heater according to the invention with the removable storage chamber 3 may be designed so that firewood and ignited on the floor 23 or an additional inserted intermediate floor.
  • the heater is then used as a combi unit and can optionally with the granular fuel - for example Wood pellets. Foliage pellets, straw pellets or the like - or be fired with firewood, briquettes or similar fuels.
  • the volume body 5 is conical with a tapering in the direction of the storage chamber 3 cone.
  • FIGS. 13 and 14 is the solid body 5 realized in a pyramid shape.
  • a tip of the cone is the opening 19 of the storage chamber 3 facing.
  • the volume body 5 may be frustoconical or truncated pyramidal or designed in the manner of a dome or an octahedron.
  • the storage chamber 3 can be embodied, for example, insulated on the inside, so that the temperature of the flames increases.
  • the storage chamber 3 may be executed, for example, perforated at least in sections or have openings which improve the supply of oxygen or air.
  • the volume body 5 is realized a substantially horizontal extended, circular plate.
  • the volume body 5 is formed in the manner of a baffle plate. From the bottom of the plate 5 beating flames surround the plate and are thereby enlarged in accordance with the invention.
  • the baffle plate 5 also offers in a known manner the possibility to bring about a strong turbulence of the fuel gases and to provide an optimized supply of oxygen.
  • the baffle plate 5 may be executed perforated, or it may be spaced from each other two baffles or two other solids are provided.
  • the opening 19 in any case partially occlusive Cover can be provided with a small opening compared to the opening 19.
  • the cover may be placed on the opening 19, for example, after the ignition and firing of the granular fuel.
  • By partially covering the opening 19 or by placing a cover with a recess reduces an effective cross-sectional area for the passage of fuel gases into the flame chamber 1. It thus results in a higher pressure of the fuel gases or a higher flow rate with the result that the Flames spatially concentrated and appeared larger than usual.
  • the recess may be provided in the cover immediately below the volume body 5.
