Siemens Steam Turbines (SST)
SST-200 steam turbine for economical
production of heat and power Whether you need power generation for independent power production or for any industrial application, the SST-200 steam turbine offers you the flexibility, reliability and economy of operation you demand.
The SST-200 range: proven design for a wide range of applications The SST-200 is a single casing steam turbine in packaged and skid-mounted design. It represents a solution based on long experience of both mechanical and generator drives in a variety of industrial applications.
Operational capability The SST-200 turbine is developed to achieve high efficiency for generator generator drives combined with high reliabil reliability ity for mechanical mechanical drives, and is characterized by easy handling, facilitated by the modular mod ular pack package. age. SST-200 drivers are designed for automatic operation needing no special consideration during operation.
Robust solutions for both mechanical and generator drive applications

The 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 are: • ethylene plants • ammonia or fertilizer plants • methanol plants These reliable and flexible turbines are also the turbines of choice for generator drives, especially in biomass plants or biomass-fired applications. applications. For generator drive an epicyclic gearbox combined with the generator is preferred, since this provides high efficiency together with a very compact arrangement.
Turboset with SST-200 steam turbine up to 10 MW
Power Generation
Reliability and efficiency from proven technology
Operational flexibility
Easy installation and maintenance
Back pressure or condensing with internally controlled extraction and possibility of several bleeds allows the selection of optimal solutions for the industrial applications.
The SST-200 turbines and auxiliaries are mounted on a skid. The entire package is assembled and wired in the workshop prior to delivery. Mechanical drive units are designed according to API (American Petroleum Institute) standards.
Back pressure and condensing turbines are available with upward or downward exhaust. The blading design for industrial applications enables flexibility of operation without disturbance for extensive and rapid changes of load. This design provides for high efficiency over the whole operation range, giving the customer highly flexible plant operation. To ensure good steam consumption at full and part loads, the turbines are designed with flow control. A multi-stage control valve system incorporating very few and well protected parts ascertains reliable steam flow control.
Our proven installation and maintenance concept lowers maintenance cost by enabling easy access to the installed components. Several maintenance concepts are available for different modes of operation.
Optimum performance The turbine casing and casing components are designed to permit short start-up times. Internally controlled extraction gives high efficiency over a wide range of flow.
