ABSTRACT:
Nozzle segments mounting vanes are received in circumferentially extending, generally dovetail-shaped grooves in an outer casing of a steam turbine, the nozzle segments forming part of a stage with rotating buckets of the steam turbine. The inclined slashfaces of the adjoining bases of the nozzle segments are provided with circumferentially opening slots to receive spline seals. The spline seals preclude or minimize steam leakage flow past the gap between the adjoining nozzle segments thereby enhancing the steam flow through the partitions of the nozzles.
