It comprises a hopper 1, a boiler 2, a horizontal spindle 3 for the supply of the combustible product, a helical rod 5 for advancing the combustible product and ashes through the burner 4, a fan 6 for propelling air to the burner 4, a lower spindle 7 arranged under the burner 4 of the boiler 6 for collecting the residues from the burner 4, a circuit for the circulation of the smoke (fumes) and a circuit for circulating the heating air, and it is characterized in that it comprises, in the circuit for the circulation of the smoke, a heat-recovery device which includes a plurality of horizontal tubes 14 provided with a spiral in their inside via which passes the smoke and over whose external surfaces the heating air circulates in a vertical direction. The heating-air circuit passes via the outer wall of the boiler 2, utilizing the latter's heat. A high level of thermal output is achieved. <IMAGE>
