The SST-500 is a single casing, double exhaust flow steam turbine, which can be used as an entire drive or as the lowpressure module of a multiple-casing turboset, directly driven or geared. This turbine, with its capacity to operate over a wide range of speed and power, is ideal for large steam volume flows. Steam flows into the turbine via two tangential inlets to equalize thermal loading and blade stress.
Emergency stop valves and control valves are installed in the steam inlet pipes. The steam flows tangentially into the inner casing and then axially to both exhausts. The customized design of the steam path allows exact adjustment to surpass general physical limitations of the last stage blades. Double-end drive is available, if required, e.g. for booster pump drive.
