Steam Turbine SST-600 (up to 100 MW)

Description
Technical Data
Benefits
Design Concept
Package

The SST-600 is a single casing steam turbine, designed for operation with speed ranging from 3,000 to 15,000 rpm for generator or mechanical drives up to 100 MW. The turbine is used for both condensing and back-pressure applications, either geared or directly coupled.

Typical fields of application are chemical and petrochemical industry, pulp and paper mills, steel works, mines, power plants, seawater desalination plants and waste-to-energy, e.g. waste incinerators. The SST-600 is used as:

Compressor drive
Generator drive
Boiler feed water pump drive

Turbine design in accordance with DIN and API standards

The steam turbine SST-600 consists of three main modules: inlet, intermediate and exhaust sections. The complex inlet section consists of emergency stop valve, control valve, internal casing with blading and external casing. The intermediate section can be designed for straight flow, or equipped with bleeds and/or controlled extractions. A wide range of exhaust sizes and types is available for back-pressure and condensing applications. These pre-designed modules are combined to a single unit for optimum matching of the required parameters.

For direct-coupled turbines or mechanical drives, the SST-600 core turbine is mounted on a separate base frame, for geared turbines the turbine is placed on a common base frame together with a gearbox. For smaller condensing sizes, even the condenser can be integrated in the base frame. For the conventional package arrangement with downward exhaust for back-pressure, condensing applications and large direct-coupled generator drives, the turbine stands on a pedestal-type support. For ground-level installation the turbine is equipped with axial or upward exhaust.
