Systems and methods to determine fouling in a gas turbine filter

摘要

A smart filter assembly is provided, the smart filter assembly having a fouling detection instrument and a communications module. The fouling detection instrument measures the weight of the filter assembly to indicate the degree of fouling. The communications module conveys the signal from the fouling detection instrument to a control system.

主权项

1. A gas turbine filter assembly comprising:
an inlet filter house; a plurality of filter components disposed in the inlet filter house; and wherein at least one of the filter components comprises a smart filter component having an end cap, a supporting structure and a strain gauge disposed on the end cap and coupled to the supporting structure, the strain gauge being adapted to measure a physical parameter acting on the supporting structure wherein the physical parameter is correlated to a degree of fouling of the filter component; and a wireless communication module coupled to the strain gauge adapted to wirelessly communicate the parameter to a controller.
