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
  • E P-A- 1,653, 154 discloses a wood burning stove comprising a burning chamber and a wood pellet burner.
  • the connection between the wood burning burner and the burning chamber is restricted by a cover, which is removed in order to be able to activate the wood pellet burner.
  • This repositioning can be performed automatica ⁇ y such that an automatic change can be performed when the wood iogs 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,
  • Fig. 1 schematically shows an overview of essential parts of the wood burning stove with wood pellet burner in accordance with the present invention
  • Fig. 2 schematically shows an enlarged view of some parts of the wood pellet burner of Fig. 1.
  • 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 peliets 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 1 1 in order to deliver the wood pellets at a suitable rate, said rate possibly being variable, depending on the required heating level.
  • 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 1 1 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 pellets, 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.
  • the movement of the pellet burner in and out of the burning chamber may be provided by means of a rack and pinion drive or other linear movement drives instead of the mentioned spindle drive.
  • the guidance of the movement of the pellet burner in and out of the burning chamber may be provided by means of other types of rails than the rails shown in the drawings, which are rods of circular cross-section co-operating with corresponding bushings on the pellet burner system.
  • the rails may be simple rails on which sliding elements of the pellet burner are sliding, or rails on which wheels connected to the pellet burner are rolling or vice versa, rails on the pellet burner rolling on wheels mounted inside the stove.
  • the transport of the pellets from the storage means to the wood pellet burner may be provided in many other ways than the shown screw conveyor, thus e,g. the screw conveyor may be positioned horizontally instead of obliquely upwardly extending, and other types of conveyors may be used for controlled delivery of the wood pellets to the wood pellet burner.
  • the insertion and retraction of the wood pellet burner into and out of the burning chamber may be performed through a sidewall instead of through the back wall as shown in the drawings.
