Abstract: Nonsynchronous excitation under low volume operation is a major risk to the mechanical integrity of last stage moving blades (LSMBs) in lowpressure (LP) steam turbines. These vibrations are often induced by a rotating ...

Abstract: Control valves are one of the key steam turbine components that guarantee operational safety in a power plant. There are two aerodynamic aspects, which are the current focus for the development of Alstom's valves. One is ...

Abstract: The diversification of power generation methods within existing power networks has increased the requirement for operational flexibility of plants employing steam turbines. This has led to the situation where steam turbines ...
