Volume 9: Oil and Gas Applications; Organic Rankine Cycle Power Systems; Steam Turbine, 2020
Abstract During installation process, most of 1000MW-class nuclear power steam turbines will undergo certain deformations due to their own big size and heavy weight, which will change seal clearances in the steam passage. The clearance change will affect steam turbine’s efficiency, and may cause rubbing faults and even strong abnormal ...

Volume 8: Microturbines, Turbochargers and Small Turbomachines; Steam Turbines, 2017
The influence of a cylindrical strut shortly downstream of the bladerow on the vibration behavior of the last stage rotor blades of a single stage LP model steam turbine was investigated in the present study. Steam turbine retrofits often result in an increase of turbine size, aiming for more power and higher efficiency.

Installation of molten-metal seals in steam-turbine valves
Power Technology and Engineering, 2007 Gaps in valves between the stems and boxes are a source of rather large steam and heat losses in power-generating steam turbines. A unique development of specialists employed by the Vserossiiskii Teplotekhnicheskii Institut — superairtight seals (SAS) with composite materials, which permit reliable sealing of valves with minimal friction within the ...
