ABSTRACT:
This disclosure relates to a process for steam dewatering of brown coal, using a plurality of autoclaves, each of which, in cyclic sequence among the autoclaves, repeats a batch process comprised of an atmospheric pressure stage to unload the coal dewatered and to load the coal to be dewatered, a heating stage to heat and dewater the loaded coal and a depressurizing stage to lower the interior pressure for the unloading of coal, wherein the heating stage comprises first and second steaming steps successive in this order at the final period of this stage to be supplied with fresh steam from an external source, and an initial steaming step under which the autoclave is connected with the other autoclave undergoing the second heating step, thereby intensifying the steam ventilation at the second heating step.
