METHOD FOR OPERATING A STEAM TURBINE POWER PLANT AND ALSO DEVICE FOR GENERATING STEAM Abstract 5 The invention refers to a method for operating a steam turbine power plant with a steam generator (4) which is fired with brown coal, in which the brown coal is first subjected to indirect drying, preferably in a fluidized bed dryer (8). The fluidized bed dryer (8) is at least partially heated by steam from the water/steam cycle of the steam generator (4). The method according to the invention is characterized in that the energy of 1o the vapour which results from the drying of the brown coal is at least partially used for preheating the combustion air.
