Abstract
Systems and methods for measuring fouling in a gas turbine compressor include a conductivity resistance sensor disposed in a compressor inlet mouth. The degree of compressor fouling is correlated to changes in resistance measured by the conductivity resistance sensor. Measurements of resistance changes are converted to an indicia of fouling and used to trigger cleaning of the compressor.
Claims20
A fouling measurement system, comprising:
- a conductivity sensor disposed in a compressor;
- a detector subsystem that generates resistance measurements from the conductivity sensor;
- and
- a processor that converts the resistance measurements to indicia of fouling.
