can occur when compressors are subjected to rapid transients, such as the one following emergency shutdown (ESD) or power failure.
Ingestion of this ash ablates jet engine blades and vanes and the ash can melt to a molten glassy state, causing blockages which can lead to compressor surge
and possible flameout.
Eliminating compressor surge
results in tremendous compressor energy savings and operational benefits such as:
I can guess, though: violent compressor surge
, catastrophic blade failure, severe vibration, primary structure failure, impact into terrain.
is defined and discussed in detail, along with the types of instrumentation (controllers, valves, pressure and temperature transmitters) available, and which of these are most suitable for controlling surge.
Centrifugal compressor surge
and its prevention have drawn significant attention in compressor literature and editorial content.
is sometimes viewed as a common occurrence but design of a proper surge control system should be regarded as both a necessary design practice and an effective risk-mitigation measure.
The retrofit included improving the reliability of the gas turbine fuel control systems, upgrading the compressor surge
control systems, and adding instrumentation to the stations and the turbines to allow for more precise monitoring.
In order to improve the efficiency of the compressor stations, over half of the compressor units are being retrofitted with integrated, turbine-and-compressor control systems allowing them to operate closer to pipe pressure, turbine temperature pressure limits and compressor surge
Other applications include compressor surge
control and compressor suction pressure control.
