Steam Turbine GT-103
Technical Design Data:
Steam turbine control is implemented in ABB analog control system. The turbine auxiliaries are
implemented in main DCS and the data exchange between the two systems is hardwired.
(All Descriptions, Specifications and Features are correct to the best of our knowledge. Interested buyers should verify before purchasing).
(All equipment must be moved by approx May 11th, 2020. Buildiing is under demolishion and the Turbine side of the building will begin in approx 3 weeks from April 20. Act now if interested!).
