Abstract

The invention relates to a turbine plant (3), in particular a steam turbine plant, and to a method (100) for cooling a turbine plant (3), in particular a steam turbine plant. It is provided according to invention that, for the cooling of the turbine plant (3) with a turbine (29) through which a process gas (15) flows in a flow direction (27) during operation, a cooling medium (7) is drawn or blown (120) through the turbine (29) in or counter to said process gas flow direction (27) respectively, and the turbine (29) is thereby cooled (130) by the cooling medium (7). According to the invention, for this purpose, a fan (6) may be coupled to a turbine inlet (4) or to a turbine outlet (5), by means of which fan the cooling medium (7, 110) which is drawn into the turbine (29) through the turbine inlet (4) or through the turbine outlet (5) can be blown (120) through the turbine (29) in or counter to the process gas flow direction (27).
