  • Fuel gas skid

  • Burner management system

  • Feed water high pressure pump

  • Feed water heat exchanger

  • Steam separator, designed for 99.95% separation efficiency

  • Air cooled heat exchanger

  • All interconnect pipes and valves.

  • Modified ISO climate control container for housing of the control panel and MCC/VFD panel. The control system automatically adjusts the fuel – water ratio parameter to keep the steam quality at 80% at all operating levels.
