Gas turbine blades are under constant threat in today's power plants. They face extreme temperatures and pressures. Knowing what damages them is key to avoiding costly downtime. . The pictures presented here will help you identify the onset of problems that could compromise safety and lead to a forced outage—including foreign object damage, partial discharge, rotor winding distortion, overheating, contamination, fatigue and stress corrosion cracking, vibration, and loose. . The potential failure of generator rotor fan vanes and blower blades has been identified as an area for detailed risk assessment in the electric power generation industry. Liberation of fan component has caused catastrophic damage to both the rotor and stator components on a number of units. . Critical gas turbine rotating component, such as turbine blades, compressor disks, spacers and cooling fan blades are subjected to cyclic stresses during engine start-up, operation and shut-down. The lifetime of these components are usually established on the basis of probabilistic crack initiation. . bustion mechanical A gas engine turbi energy that (into e is a type of turbine which is a is an internal com-by to the gas turbine can convert natural gas or other liquid fuels to chanical es high due operating to energy rotational into rotary motion).
