Reheat Steam Turbine STF-D650
The STF-D Series is designed for main inlet conditions up to 650°C (1200°F) and 330 bar (4786 psi) and reheat temperatures up to 670°C (1238°F).
HP turbines can be equipped with a second main steam injection system by means of integrated overload valves. This method provides additional load reserve in cases of sudden steps in power demand.
Startup valves (TAL) help ensure a safe and trip-free runback from full load to house load after load rejection.
HP, IP, and valve units are shipped fully assembled enabling shorter installation time on site. The LP turbine is dispatched in pre-assembled lots for easier handling and reduced construction time on site.
Skid-mounted lube and control oil systems with pre-assembled pumps, filters, valves, and interconnecting piping are available for all turbine sizes.
Sleeved rotor couplings help ensure durable shaft alignment and smoother operation.
The STF-D650 turbine consists of separate HP, IP, and either one or two double-flow LP sections
Single bearing design reduces construction time, increases power density and enhances reliability by avoiding load shifts
