Siemens Co-Start™ Technology
Fast Bottoming Cycle Start Up
Co-Start means lots of power fast
Co-Start uses an integrated hardware and control package which enables
the steam turbine to ramp up early and quickly, while protecting
equipment for reliable operation over the life of the plant.
• No low load gas turbine hold
points
• Fast Ramp of the steam
turbine
• Base load power in about 30
minutes
