<p>The invention relates to a fluidized-bed drier with its own power supply and with built-in heating surfaces 4 for condensing heating steam, in which a steam generator 2 is connected to the drier 1 in two circuits, in which case the bulk material of the drier 1 is fluidized by the exhaust gases of a steam generator 2 before they are discharged into the free atmosphere, and the steam generated by the steam generator 2 is expanded in a back- pressure turbine 3 and the expanded steam is condensed in the heating surfaces 4 of the drier 1, and the condensate produced is fed back into the steam generator 2. If lignite or another solid fuel is used as the material to be dried, some of the dried bulk material is burned in the steam generator, as a result of which the plant becomes self-sufficient in energy. <IMAGE></p> |
