摘要

1. Process for drying granular material, in particular coal, in a fluidized bed heated by heating surfaces, whereby the discharged fluidizing agent mainly consisting of water after its cleaning is at least partially reused for fluidization and another part is withdrawn from the circuit in order to be condensed is withdrawn upstream of a circuit fan and led to a first mixing condenser and another part is withdrawn downstream of the circuit fan and led to a second mixing condenser generating a condensate temperature of more than 100 degrees C due to higher steam pressure and the condensate of the first mixing condenser is led to the second mixing condenser and the condensate of the second mixing condenser after heat emission is partly led to the first mixing condenser and the remaining part is discharged for further disposal.
