The vibration phenomena which occur in rotary machines, such as power plants, can result
in catastrophic consequences. Any failure in any power plant section can result in extended …

In this paper, the interplay and relationship between digital twin and Industrial Internet are
discussed at first. The sensing/transmission network capability, which is one of the main …

The installing angle of the static blades of the compressor in gas turbines affects the
aerodynamic forces which leads to the vibration variation of the dynamic blades, and may …

The harsh operating environment, and the extreme working condition, of the steam turbine
blades have led to the use of alloys with special characteristics. Of these properties are high …

In this study, to clarify the failure mechanism of the last-stage rotor blade in the low-pressure
cylinder of a steam turbine, the peculiarities of crack initiation and propagation on the inlet …

Due to the special working environment of steam turbine blades, such as high temperature
and cyclic stresses, they are routinely under heavy damage conditions. Of the most …

The failure mechanism of the last-stage rotor blade of the low-pressure cylinder of a steam
turbine when exposed to high-speed wet steam was elucidated. The results indicated that …

In the present study, the microstructure, toughness and cracking behavior of a batch of
X12CrMoWNbVN10-1-1 martensitic heat resistant steels used for manufacturing steam …

A steam turbine from a thermoelectric central was put into maintenance due to a forced
outage for high vibrations. Visual inspection of the steam turbine of 300 MW showed blades …

An analysis of the fracture cause for a steam turbine blade root is conducted in this study.
During the maintenance of a steam turbine, nineteen IP-6S (Intermediate Pressure 6th …
