The device has a metal enclosure (1) for a hearth (3) made of refractory brick, draught boxes (4,5) and ducts (6,7) to preheat and set in motion the combustion air. A heat exchanger (9) has a support for multiple thermo-electric devices (10) , which create an electromotive force which supplies the motor delivering sawdust to the hearth. |
