<p>Method and device for the supply of pulverized fuel material to a gas generator comprised by a vessel (1) maintained under pressure wherein are injected a combustive fluid, a moderator fluid, and a mixture (8) containing a solid carbonaceous fuel reduced to powder, that is introduced in the vessel of the reactor by means of a screw conveyor forming at the inlet of the vessel (1) a plug (80) of compressed material tight to the pressure of the reactor (1) and continuously renewed as it is introduced. According to the invention, for the driving and compression of the mixture (8) introduced in the vessel, by using at least two screws (2, 3) intermeshed, with similar helical threads, rotatingly driven in the same direction inside a sleeve (4) which envelopes them, the pressure-tight plug of compressed material introduced in the pressure vessel (1) contains at least 85 % of solid material and remains friable when entering the vessel (1) of the reactor.</p> |
