Abstract
The application concerns a method for drying a fibrous material by means of a process gas stream flowing through a pipe, including heating the process gas flowing through the pipe by means of a heater with controllable heating power, and conducting a portion of the process gas stream through a bypass pipe bypassing the heater, wherein the ratio of mass flows of process gas flowing through the heater and through the bypass pipe is adjustable, and is distinguished by the fact that the heating power of the heater is controlled according to the set ratio of mass flows of process gas through the heater and through the bypass pipe. The application further concerns a corresponding drying apparatus.
