Description

GE’s STF-D Series is a modular product platform for utility reheat steam turbines in the 100 to 1,200 MW power output range. OUR REHEAT STEAM TURBINES MODULAR Our reheat steam turbines modular concept governs all engineering and manufacturing processes, and results in reduced construction and commissioning times, higher reliability, and excellent efficiency TO ENHANCE PERFORMANCE To enhance performance, the steam path is always adapted to the specific project requirements THE EXTENSIVE LP LAST STAGE BLADE The extensive LP last stage blade portfolio for 50 and 60 Hz models offers rear stage sizes from 30 inches up to 49 inches. The number and size of LP turbines can be tailored to specific site conditions—for example, the STF-D1050 steam turbine configuration can have up to five casings Designed for Efficiency and Reliability 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.
