Furthermore, the invention relates to a change system for the combustion chamber in this firing device.
  • Patio heaters of known design are mainly operated with flammable gases from pressure bottles. If the gases are of fossil origin, there is the disadvantage of a negative CO 2 balance.
  • a patio heater which has a firing point which is designed as a combustion chamber which can be filled with wood pellets and has a cross-sectional area which is constant in the vertical direction.
  • a hot gas guide device and a reflector body are arranged above the combustion chamber.
  • the combustion chamber has, in an upper region near the reflector body, a flame tube with a diameter which is reduced in comparison with the combustion chamber and the hot gas guide device, in order to guide the hot air generated in the combustion chamber in a compressed form in the direction of the reflector body.
  • several primary air openings are arranged in a level below the burning level of the wood pellets.
  • several secondary air openings are arranged in the area of the upper end in a level above the burning level of the wood pellets.
  • the DE 10 2013 100 972 A1 describes a device for generating a column of light, with a furnace for generating a flame suitable for forming a column of light.
  • the furnace is designed as a combustion chamber that can be filled with wood pellets and has a constant cross-sectional area in the vertical direction.
  • a substantially horizontally oriented focal plane of the wood pellets is formed between the upper end and the lower end of the combustion chamber.
  • a flame-guiding device is provided for guiding the flame generated in the combustion chamber into the ambient air, an air flow provided between the flame and the flame-guiding device cooling the flame-guiding device and shielding it from the flame and, on the other hand, the formation of a long flame as a pillar of light causes.
  • a patio heater heater for lighting, heating the environment and heating liquids is out of the DE 20 2011 001 786 U1 known.
  • the patio heater has a firing point for operation with lumpy biomass, such as wood pellets, which has a fuel interior, a cover with a central flame outlet opening and a fuel pipe above it. Combustion air regulation is provided between the fuel interior and an outer fuel jacket.
  • the DE 20 2008 007 919 U1 describes a radiant heater with a combustion chamber for burning wood pellets, which is connected to a radiation pipe arranged perpendicular to the combustion chamber. At the end of the tube facing away from the combustion chamber, the radiation tube has a hollow roof which is open at the bottom and which has the shape of a flat mushroom cap.
  • an outdoor furnace which has a burner for burning solid fuel, for example pellets.
  • the cylindrical or prismatic burner is height-adjustable in a housing by means of a lifting device via a spring device.
  • the EP 3 163 162 A1 describes a mobile radiant heater with a combustion unit for burning fuel, a radiation unit for radiating combustion heat, a storage unit designed separately for the combustion unit for storing the fuel and a transport unit for moving the entire mobile radiant heater.
  • the units can be exchanged between different types of radiant heaters.
  • the housing of the radiant heater has a receiving space for the combustion unit, which is designed to interchangeably accommodate the combustion unit.
  • a separate chassis for the firing unit is not provided.

  • the chimney has a housing with rings for engaging the mobile chimney section, from which a flexible tube leads to a chimney.
  • the DE 20 2006 008 993 U1 describes a real fire fireplace for domestic heating, which is surrounded by a combustion chamber that can be opened at the front and has a fireplace floor with a fuel tank.
  • a chimney support stand of the real fire fireplace has wheels with which the entire real fire fireplace can be moved like a toboggan.
  • Biomass wood pellets
  • wood pellets is known to consist of flammable and non-flammable components. If wood is burned, about 80% of the amount burns in a reaction with combustion air, which has flame and heat as process waste. The non-flammable components result in the ember stick, which takes a long time to burn out, i.e. cold. In this process, considerable residual heat is still released to the environment.
  • the object of the invention is to avoid these disadvantages and to increase the useful life of combustion sites operated with biomass for outdoor use.
  • the interchangeable burner unit is designed to be movable, the interchangeable burner unit having a chassis with at least two wheels or rollers, and preferably the interchangeable burner unit together with the combustion chamber is designed as a mobile burner carriage.
  • the still hot replacement burner unit with the glowing stick still glowing can be removed from the firing device and replaced by a freshly filled replacement burner unit.
  • the operation of the firing device is only interrupted briefly, for example for a few minutes.
  • the replacement burner unit, freshly filled with biomass in the combustion chamber, can be put into operation immediately after being replaced in the combustion device.
  • the furnace can therefore develop its full heat again after a short time.
  • the combustion chamber is detachably, preferably loosely, connected to the chassis. This enables the combustion chamber to be removed quickly from the chassis and a simple return of the combustion chamber.
  • the combustion chamber has at least one, preferably hook-like, receptacle for a manipulation device, the manipulation device preferably having a heat protection shield.
  • the manipulation device can be suspended in the receptacles via finger-shaped U-shaped holding brackets, as a result of which the combustion chamber can be lifted up with the manipulation device without risk of injury.
  • the interchangeable burner unit preferably has an integrated ash drawer below the burner chamber, which is preferably integrated in the chassis. This can be dimensioned in such a way that the ash can be absorbed in several combustion cycles. When the interchangeable burner unit is removed from the firing device, all the ash is also removed.
  • the removed interchangeable burner unit with the afterglow glow stick can slowly cool down outside the firing device and then be prepared for the next use by emptying the combustion chamber and the ash drawer and refilling the combustion chamber with biomass.
  • the burner nozzle is arranged fixed in the housing in the firing point.
  • the burner nozzle thus remains in the housing of the firing device when the interchangeable burner unit is replaced. This allows the height and weight of the interchangeable burner unit to be kept as small as possible. It is particularly advantageous if a defined gap is formed between the combustion chamber and the burner nozzle when the interchangeable burner unit is inserted into the housing. On the one hand, the gap enables the interchangeable burner unit to be moved in and out of the firing device without jamming and, moreover, can act as a secondary air supply opening in order to improve the combustion.
  • an exchange system for the combustion chamber in the firing device with at least one alternating burner unit is provided according to the invention, the firing device having at least one receiving space for receiving at least one alternating burner unit.
  • the exchange system additionally has a warm box and / or a heat table with at least one second receiving space for receiving at least one interchangeable burner unit.
  • the still hot replacement burner unit can be moved out of the firing device and exchanged for a freshly filled replacement burner unit, which was kept in the cold box in the warming box or in the heating table.
  • the still hot replacement burner unit is moved into the receiving area of the warming box or the hot table and can then heat up and cool down while releasing its residual heat.
  • the annealing process of the burned-out burner unit still provides enough residual heat to comfortably warm the area of the warming box or the hot table. Since the burning process and the annealing process take about the same amount of time, the areas of the warming box or the heating table can be heated for longer periods in continuous operation for people who are outdoors, with only brief interruptions in the heat release during the exchange of the burner units enter the warm box or hot table.
  • Fig. 1 shows a firing device formed by a patio heater 100, which has a housing 110 in which a firing point 1 for the outside area for the combustion of wood pellets is arranged.
  • the patio heater 100 also has a support structure 120 for a roof 200 connected to the housing 110.
  • a tubular radiation body 130 runs between the firing point 1 and the optional roof 200, the outer surface of which is surrounded by a suspended contact protection.
  • An upper part 140 with a fine dust filter 150 and a combustion adjustment device 160 adjoins the radiation body 130 at the top.
  • Reflective mirror covers 210 and LED lighting 220 are provided in the roof 200 ( Fig. 2 and Fig. 4 ).
  • a circumferential LED lighting 220 is integrated in the roof 200.
  • the mirror diaphragms 210 which are also arranged all around in the roof 200, are arranged in such a way that the heat radiation emitted during the burning process and the flame light are reflected there.
  • the angles of inclination of the mirror diaphragms 210 are selected such that the largest possible radius is emitted.
  • the mirror covers 210 Another function of the mirror covers 210 is the exhaust gas routing. If the mushroom-shaped patio heater 100 is not heated, it can serve as an outdoor lamp due to the integrated LED lighting 220. In this case, the integrated mirror covers 210 reflect the light from the LED lighting 220.

  • the interchangeable burner unit 510, including the combustion chamber 2 can be inserted into or pulled out of the first receiving space 530 of the housing 110 of the patio heater 100.
  • the interchangeable burner unit 510 which can be moved by the chassis 560, it is possible, after the end of the burning process, to replace the combustion chamber 2 together with the burned-out wood pellets very quickly by a combustion chamber 2 freshly filled with wood pellets, and thus the operation of the patio heater 100 after a very short interruption continue.
  • the change system 500 can have a heat box 540 and / or a heat table 550 which serves to store at least one change burner unit 510, the heat box 540 or the heat table 540 being designed to receive the change burner unit 510 with a corresponding second receiving space 535 for receiving the change burner unit 510 ,
  • the interchangeable burner unit 510 and the combustion chamber 2 are constructed in such a way that they can be introduced both into the first receiving space 530 of the patio heater 100 and into the second receiving space 535 of the heating box 540 (storage box) or into a heating table 550.
  • the heat box 540 and the heat table 550 are designed such that the embers of the interchangeable burner unit 510 accommodated in the second accommodating space 535 can completely burn out.
