Abstract (en)
[origin: EP1288502A2] The turbine has a housing (1) with rotor (12) and stator plates (14), which have blades on support rings (16,18). The stator plate (20) facing the higher pressure area is connected with its support ring (22) to a housing component (24). The component and the stator plate each have a cooling water channel, or the housing component may have a heater, and it is thermally insulated relative to the rest of the housing.
