An industrial sensor for reliable ice detection in gas turbines
- Vibro-Meter SA, Fribourg (Switzerland). Dept. of Machinery Monitoring and Diagnostics
Ice formation in the intake duct and compressor blading is a constant risk on gas turbines operating in regions where there are unfavorable ambient conditions. If allowed to continue there is a clear danger that pieces of ice will be ingested by the machine causing substantial damage. To protect the machine from possible damage, if ice is suspected by the operator the de-icing system is activated, injecting hot bleed air from the last compressor stages into the cold inlet air, naturally causing a decrease in power and efficiency. There exists a requirement for an ice detection system which will reliably detect the presence of ice and therefore optimize the use of bleed air for de-icing and reduce unnecessary power and efficiency losses. This paper discusses the necessary conditions for icing and describes a robust industrial sensor for reliable ice detection. The system, which is suitable for ground based gas turbines, has been installed on a 130MW gas turbine in Holland for the last three years and some of the results are presented here together with the economic advantages to be gained from installing such a system.
