Abstract
A sealing bar is provided for each gap between adjacent shroud plates to form part of the coolant recovery system of an open-circuit, liquid-cooled gas turbine. The undersides of the edges of the shroud plates at each gap are chamfered and a small cylindrical bar is supported in the recess provided thereby. Centrifugal force urges the bar into sealing engagement with the chamfered surfaces.
