ABSTRACT:
The invention relates to a multistage brush seal of a steam turbine that comprises several brushes which in turn comprise several bristles. A plurality of brushes are arranged next to each other and are configured different from each other with regard to the length of the bristles, or to the bristle thicknesses, or to the bristle rigidities, or to the lay angle of the bristles, or to the height of a first guard ring in front of or behind the brush seal in the flow direction, which delimits this brush seal, or to a gap between the bristles and an opposing surface.
