Siemens, SST-400, 30 MW, 50 Hz, Condensing Steam Turbine Generator Package

Siemens, SST-400, 30 MW, 50 Hz, Condensing Steam Turbine Generator Package

Description

  1. Overview
    1. Siemens SST-400 condensing steam turbine package.
    2. Turboset guaranteed output: 30,000 kW at generator terminals.
    3. Frequency: 50 Hz.
    4. Typical SST-400 applications include industrial/captive power, biomass, waste-to-energy, CHP/district heating, pulp and paper, chemical, sugar, steel, geothermal and related steam-power applications.
  2. Technical Specification
    1. General information: manufacturer, turbine model, configuration, rated output, frequency and application.
    2. Steam turbine: axial-flow, single-casing, reaction-bladed SST-400; fixed-pressure operation; superheated steam; 128 bar(a); 535°C; 31.34 kg/s; five bleeds; turbine/control/protection equipment.
    3. Reduction gear unit: single-helical high-speed parallel-shaft, single-stage; 35,375 kW maximum continuous rating; 5,458 rpm input; 1,500 rpm output; AGMA 421.06.
    4. Synchronous generator: 38 MVA; 32.30 MW; 10.5 kV; 2,089 A; PF 0.85; 50 Hz; four pole; 1,500 rpm; IP54; star connection; class F; 98.50% efficiency at rated PF/full load. Include cooler, excitation, monitoring and AVR information.
    5. Performance / operating data: state the documented 30 MW generator-terminal guarantee point and relevant Siemens operating conditions. Do not invent performance guarantees.
    6. Auxiliary systems: integrated 15,000-L lubrication system, main/auxiliary/emergency pumps, dual oil coolers, dual filters, jacking system, separate HP control-oil skid, control/protection and monitoring systems.
    7. Scope / documentation: state that extensive Siemens technical documentation, P&IDs, performance curves, generator documents and electrical/control documentation are available. Do not claim that the condenser or balance-of-plant equipment is included unless physical inventory confirms it.
