The single casing turbine with horizontal joint flange has a symmetrical casing, which allows short start-up times and quick load changes. It has a compact and flexible design with a high degree of standardization.
Internal valve arrangements, controlling the steam flow to the back end of the turbine, are used to maintain constant process steam extraction pressures over a wide flow range. The SST-300 rotor is of solid forging, and is fitted with resonance-proof blading, the reliability of which is further enhanced by a combination of shrouded blade tips and low static steam-bending stresses that keep the total stress load on the blades to acceptable levels. The reduction gears are taken from the existing range of world-class gear manufacturers and have proven high reliability and performance.
