Abstract

A steam turbine with a steam inlet region, an exhaust-steam region and a blading region surrounded by a turbine housing and disposed axially therebetween. Furthermore, a cooling-fluid inlet is provided which can be closed and opened by a closing member and through which cooling fluid can be introduced into the turbine housing. The introduced cooling fluid can be conducted out of the turbine housing again via a suction device for sucking out the cooling fluid. The invention relates, furthermore, to a steam turbine plant and to a method for cooling the steam turbine.
