Definitions

  • the present invention relates to a wood burning stove with wood pellet burner of a kind, in which there is provided a possibility of burning either wood logs or wood pellets, and where the burning of wood pellets can be performed in an automated manner.
  • wood burning stoves with wood pellet burners it has been known to rearrange the components of the wood pellet burner manually in order to make it possible to burn wood logs, whenever this is desired.
  • a wood burning stove with wood pellet burner of this kind is known from the firm Bioline.
  • Bioline construction a covering has to be placed manually on top of the wood pellet burner in order to be able to burn wood logs in the stove. A corresponding manual removal of the cover is required in order to be able to start the wood pellet burner.
  • This repositioning can be performed automatically such that an automatic change can be performed when the wood logs in the burning chamber are burned out. Automatic introduction of the wood pellet burner into the burning chamber and starting thereof can be performed without any manual intervention.
  • the wood burning stove with a wood pellet burner shown in Fig. 1 comprises a burning chamber 1 provided with a refractory lining 2.
  • a wood pellet burner generally indicated by the number 3, comprises, as shown in Fig. 2 , a fire pot 4 provided with a grate 5 for supporting the burning wood pellets 19, combustion air being supplied from underneath the grate 5 via an air supply tube 6.
  • the wood pellets 19 will be ignited when starting up the wood pellet burner by means of a hot bulb 7 positioned in a separate part of the air supply tube 6 separated from other parts of this air supply tube 6 by means of a separating wall 17, whereby the air supplied via the separated part of the air supply tube containing the hot bulb 7 will have a sufficiently high temperature to ignite the wood pellets 19.
  • Supply of wood pellets 19 to the fire pot 4 is provided from a wood pellet storage 20 by means of a screw conveyor 10 extracting the wood pellets 19 from the wood pellet storage 20 and delivering the wood pellets to a supply tube 9, through which the wood pellets fall down on the chute 8 for receiving the wood pellets and delivering the wood pellets to the fire pot 4 on top of the grate 5.
  • the screw conveyor 10 is driven intermittently by a motor 11 in order to deliver the wood pellets at a suitable rate, said rate possibly being variable, depending on the required heating level.
  • the delivery of combustion air via the air supply tube 6 and the flexible tube 16 is provided by means of a fan, not shown in the drawings, said fan possibly being controlled in its velocity in order to deliver a suitable amount of combustion air corresponding to the amount of wood pellets delivered to the fire pot 4.
  • the hot bulb 7 is naturally only used for ignition when starting up the wood pellet burner, and as soon as the wood pellets 19 are burning inside the fire pot 4, the hot bulb 7 is no longer supplied with electricity to heat up the combustion air delivered thereby.
  • the parts of the wood pellet burner comprising the fire pot 4, the back wall 18 and the wall section 15 are movable in a longitudinal direction along the slide bars 14 controlling said sliding movement, and said movement is furthermore controlled by the spindle 12 driven by the motor 13.
  • the wood pellet burner 3 can be moved to the right as seen in Fig. 1 , whereby the wall section 15 is brought into alignment with the refractory lining 2 of the burning chamber 1, whereby the burning chamber 1 is freed from all the components of the wood pellet burner 3 and thus can be used for burning wood logs or the like.
  • the burning chamber 1 is supplied with primary air for the burning of wood logs through a grate at the bottom of the burning chamber and the burning wood delivers heat by the combustion air circulating inside the burning chamber and through suitable channels connecting to a chimney.
  • the burning chamber may, as is ordinary within the art of wood burning stoves, be provided with a glass door such that the burning wood or burning wood pellets can be viewed from outside.
  • control of the electrical components I.e. the hot bulb 7, the spindle motor 13, the screw conveyor motor 11 and the combustion air fan, are controlled automatically in order to secure the correct functioning of the stove.
  • different temperature sensors are provided in order to secure this correct functioning of the stove, whereby detection of correct ignition of the wood pallets, the burn out of possible wood logs can be detected correctly in order to automatically shift from wood log burning to wood pellet burning, based on e.g. a thermostat detecting the room temperature close to the stove.
  • the control of the insertion and retraction of the wood pellet burner components may comprise detectors for detecting the end positions of the wood pellet burner components, and furthermore in order to avoid faults due to possible blocking of the movement due to residual material inside the burning chamber 1, an over-current detection on the motor 13 for the spindle 12 may be provided such that insertion of the wood pellet burner components into the burning chamber 1 can be stopped without destruction of any of the components and a fault report or signal be set when such fault has been detected.
