<p>1. A device for converting and recovering thermal energy comprising a conversion chamber of cylindrical shape provided at one end with means for producing an exothermic reaction giving off gases at high temperature and communicating at its other end with a recovering chamber comprising a heat recovering structure constituted by at least two coaxial tubular exchange surfaces defining a central space (20) and an annular space (10) through which travel in opposite directions gas currents, the assembly being placed inside an outer container (1) capable of resisting pressure and defined by a cylindrical lateral wall (11) closed at its ends by an upper end wall (12) and a lower end wall (13), characterised in that the conversion chamber occupies the whole of the central space (20) whose height defined by the two end orifices corresponds to the distance required for the development of the conversion reaction and is completely surrounded by the recovering chamber placed in the annular space (10), the conversion chamber (20) communicating with the recovering chamber (10) through a circular gap (3) in which is produced the separation of the ashes entrained with the gases issuing from the conversion by inversion of the direction of the gaseous current at the outlet of the conversion chamber (20).</p> |
