Detection of damage in steam turbine blades caused by low cycle and strain cycling fatigue

Engineering Failure Analysis, 2019
The blades of steam turbines are exposed to low cycle fatigue, as well as to strain cycling fatigue, which may cause their structural deterioration after a low number of cycles. This represents the blade damage in steady condition of operation, which may

Performance improvement of the bottoming steam Rankine cycle (SRC) and organic Rankine cycle (ORC) systems for a triple combined system using gas turbine (GT) as topping cycle

, 2020
In the present study, performance improvement of SRC and ORC systems used as a bottoming system in a GT based triple combined system was evaluated for varying turbine inlet temperature and pressure. In the first step, SRC was parametrically optimized for

Corrosion fatigue failure of steam turbine moving blades: A case study

, 2019
This paper describes the failure of a rotor of a condensing industrial steam turbine installed in a fertilizer production plant. There was a fracture of the two adjacent rotor blades in their roots. An analysis of the failure cause was carried out, which
