A process for drying a wet material in a drying system includes supplying a current of heated gas to a dryer from a combustion chamber. The material is exposed to the current in the dryer. The dried material is separated from the current of heated gas. The current of heated gas is split into a first stream of heated gas and a second stream of heated gas after the dried material has been separated. The first stream of heated gas is introduced into the combustion chamber so that the first stream is further oxidized therein. A third stream of heated gas is removed from the combustion chamber. The third stream includes at least a portion of the first stream. The second stream of heated gas is introduced into the combustion chamber so that it makes up a portion of the current conveyed to the dryer.
