wood pellets 19 to thefire pot 4 is provided from awood pellet storage 20 by means of ascrew conveyor 10 extracting thewood pellets 19 from thewood pellet storage 20 and delivering the wood pellets to asupply tube 9, through which the wood pellets fall down on the chute 8 for receiving the wood pellets and delivering the wood pellets to thefire pot 4 on top of the grate 5. Thescrew 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 theflexible 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 thefire 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 thefire pot 4, the hot bulb 7 is no longer supplied with electricity to heat up the combustion air delivered thereby. - As shown in
FIG. 1 , the parts of the wood pellet burner comprising thefire pot 4, theback wall 18 and thewall section 15 are movable in a longitudinal direction along theslide bars 14 controlling said sliding movement, and said movement is furthermore controlled by thespindle 12 driven by themotor 13, By this moving mechanism, the wood pellet burner 3 can be moved to the right as seen inFIG. 1 , whereby thewall section 15 is brought into alignment with therefractory lining 2 of theburning chamber 1, whereby theburning 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. - Preferably, 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. - Preferably the 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. Preferably, 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 themotor 13 for thespindle 12 may be provided such that insertion of the wood pellet burner components into theburning 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. - Above the invention has been described in connection with a specific embodiment thereof, however, many modifications may be envisaged without deviating from the main principles of the invention. Among such deviations, the following may be stated.
