The SST-200 is a single-casing steam turbine in a packaged base frame-mounted design. Developed to achieve high efficiency for generator drives combined with high reliability for mechanical drives, the SST-200 is characterized by easy handling.
Both back pressure and condensing turbines, with and without extraction or bleed points, are characterized by a robust layout, essential for driving compressors, pumps and fans in the chemical and petrochemical industry. Some specific applications:
Generator and mechanical drive
>Ethylene plants
>Ammonia or fertilizer plants
>Methanol plants
Design Concept
SST-200
>Single casing turbine
>Base frame mounted packaged unit design
>Proven, modular and thermoflexible design
>Customized steam path
The turbine casing and casing components of the SST-200 are designed to permit short start-up times. For generator drive, there is a possibility of conventional arrangement with integrated generator, since this provides high efficiency together with a very compact arrangement.
Back pressure or condensing applications with internally controlled extraction and possibility of several bleeds allow the selection of optimal solutions for the majority of industrial applications. Internally controlled extraction gives high efficiency over a wide range of flow. A multi-stage control valve system incorporating very few and well protected parts ascertains reliable steam flow control and good steam consumption. Both back pressure and condensing turbines are available with upward or downward exhaust.
