SCF 10 MW - 100 MW

Single flow, same flow direction for the entire bladed path. Full arch admission with reaction blades as well as control stage version are available. Very simple mechanical scheme to meet the highest performance and reliability standards of a wide and diversified market, from industrial applications to geothermal needs. High speed and direct coupling available.






SRCF 30 MW - 150 MW

Single flow, HP section flow in opposite direction to IP and LP (reverse) flow, single cylinder. This turbine standard has been developed to answer to needs of our customers both in the industrial and utility sector. Full arch, fully reaction HP section version is available as the control stage version, to fit any operational configuration. Machine of this configuration may be realized with or without reheat starting from the smallest sizes.




DC / SL - DL 50 MW - 250 MW

Two cylinders, single LP cylinder. This configuration covers with state of the art performances a broad range of applications: typical are combined cycles, solar and biomass with big flexibility in steam conditions provided by different versions of the same basic standard. Sliding pressure operations with full arch admission is typical although control stage versions can be supplied as well. This arrangement allows to choose the optimal relational speed for each machine section, also setting one turbine module on each side of the generator.

HIC / DL - ML 100 MW - 500 MW

This type of machine is made by a HP/IP combined cylinder plus a double flow LP turbine (HIC-DL). The same concept is applied with two LP turbines when larger exhaust areas are needed. State of the art technology allows to reach the highest possible efficiency rate when a compact configuration is requested. Fossil power plants and combined cycles are the usual field of application, also in association with district heating and other CHP schemes.




DHI / DL - ML 300 MW - 850 MW

Machines to be applied in large, typically coal-fired power plants. Leading edge technology, both in mechanical and aerodynamic design ensures the best efficiency and reliability either in USC or SC configurations. Full arch admission and full reaction blading.








Impulse type turbines up to 150 MW

Customers choose Franco Tosi Meccanica impulse type turbines because of their extreme robustness, simplicity and operational flexibility.

DESIGN FEATURES
