How to Request a Quote for a Steam Turbine Generator Skid (RFQ)
Please provide the following steam balance and power parameters:
- Inlet Steam Conditions: Pressure (barg/psig), Temperature (°C/°F), and Flow Rate (tons/hr).
- Exhaust Conditions: Backpressure (barg) or Vacuum Condenser temperature.
- Required Electrical Output: kW or MW, Voltage (e.g., 6.6 kV, 11 kV, 400V), 50 Hz.
- Extraction Steam Demand (if extraction turbine required: Flow tons/hr at desired pressure).
