Siemens Steam Turbines for 100 MW - For Sealing Compound for Turbines Call +91-891-2564393

  1. 1. SST-600 Industrial Steam Turbines Up to 100 MW Whether you need power generation for independent power production or for any industrial application, the SST-600 offers you the flexibility, reliability and economy of operation you demand. The SST-600 range: proven design for a wide range of applications 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 drive up to 100 MW. It covers industrial applications such as: Compressor drive Generator drive Boiler feed water pump drive for chemical and petrochemical industry, pulp and paper mills, steel works, mines, or in power plants, seawater desalination plants, solar thermal power plants, and waste-to-energy, e.g. waste incinerators.Industrial Steam TurbinesAnswers for energy.
  2. 2. Design features The SST-600 single-casing steam turbine is used for both condensing and back-pressure applications, either geared or directly coupled. Turbine design is in accordance with DIN or API standards. The turbine is built up from pre-designed modules combined to a single unit for optimum matching of the required parameters. The SST-600 turbine can be equipped with impulse control stage and reaction blading fixed in blade carriers. Steam is led into the turbine by one or two emergency stop valves, which, together with the control valve chest, form an integral part of the turbine casing. The intermediate section of the turbine can be equipped with one or two internally controlled extractions and number of bleeds as required. The exhaust section is prepared for axial, downward or upward connection for condensing, while for back-pressure application upward or downward connection is provided. The casing is supported by a front bearing pedestal to absorb axial movements and a fixed rear bearing pedes- tal. Bearing pedestals are fixed on the base frame or directly anchored to a concrete foundation. Turbine auxiliary systems are also pre-designed into modules covering the complete range of turbine sizes. Operational flexibility The turbine concept together with its modular configu- ration ensures high stress absorption during turbine operation whilst maintaining high flexibility in design. The design with outer casing or the combination of the inner and outer casing substantially reduces thermal and pressure stress. Together with the unique bearing pedestal design and its arrangement, this improves the operational stability and reliability of the turbine.Modular layout and compact design 1 2 3Typical dimensions fora 35-MW steam turbineL Length 15 m / 49 ft HW Width 6.5 m / 21 ft WH Height 4.5 m / 15 ft 4 51 Steam turbine 52 Speed reduction gear L3 Generator4 Base frame with integral oil unit5 Condenser6 Condensate and vacuum pump package 6Typical layout for turboset with a SST-600 condensing steam turbine
