Systems and methods to determine fouling in a gas turbine filter
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.
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.
2. The filter assembly of claim 1 , wherein the smart filter component further comprises a plurality of stain gauges radially disposed around a center mount hole on the end cap.
3. The filter assembly of claim 1 , wherein the physical parameter is a weight of the filter component.
4. The filter assembly of claim 1 wherein the communication module comprises a wireless communication system operating in accordance with a Bluetooth standard.
5. The filter assembly of claim 1 , wherein the the physical parameter is a force acting on the supporting structure.
6. The filter assembly of claim 2 , wherein the physical parameter is a torque acting on the supporting structure.
