Definitions

  • the present disclosure relates generally to monitoring parameters of component located in a working fluid and particularly to the installation of measurement devices in a gas turbine steam turbine, HRSG, or boilers.
  • a direct measurement solution is discussed in US patent application 2006/0056959 A1 .
  • the solution involves providing a component for use in a combustion turbine having a substrate with a micro-electromechanical system (MEMS) device affixed to the substrate. At least one deposited connector is in electrical communication with the MEMS device and is used to route a data signal from the MEMs device to a termination location.
  • the MEMS device is deposited in a number of trenches in a thermal barrier coating of the component.
  • a component and a simplified method for retrofitting a component with a sensor are provided.
  • the disclosure is generally based on fixing a coupon embedded with a sensor to a working fluid exposed component.
  • coupons are a known to be used to repairing components the solution provides a simple means of retrofitting components with sensors, in particularly during component repair.
  • a Component that is configured to be exposed to the working fluid of a turbine such as a turbine blade, comprises a coupon that is fitted, such as by welding, in or located on the component and a measurement sensor embedded in and/or located on the coupon.
  • the sensor may be configured to measure one or more of a selection of temperature, pressure and strain.
  • the sensor is a self-powered, wireless sensor which may include an antenna.
  • a coating such as a thermal barrier coating covers an outer layer of the sensor and at least part of an outer surface of the coupon.
  • the component includes a measurement channel with a first opening through a surface of the component and a second opening fluidly connected to the sensor.
  • An aspect includes a method of fitting and joining a sensor to a turbine blade, comprising the steps of forming a cavity in the turbine blade, forming a coupon fittable within the cavity, embedding a sensor in or on the coupon and fitting and joining the coupon, with the sensor, in the cavity.
  • the method includes the step of coating the coupon with a thermal barrier coating after the step of fitting and joining of the coupon.
  • a component has a cavity 6 in which a coupon 8 having an embedded sensor 14 may be fixed.
  • a surface of the sensor 14 and at least part of a surface of the coupon 8 is covered with a coating 12, such as a thermal barrier coating, to protect the sensor 14 and the coupon 8.
  • the coating 12 may also extend over the component 2.
  • the sensor may be any type of MEMs sensor including self-powered wireless sensors configured to measure temperature, pressure and/or strain.
  • the coupon 8 may be fixed within the cavity 6 using any known method of fixing coupons to components as part of component repair methods.
  • the fixing/joining may therefore include, brazing and/or welding, including laser welding.
  • coupon 8 may be part of a turbine blade 4.
  • the embedded sensor 14 may further include an antenna 16, also embedded in the coupon 8, to embedded wireless communication with the sensor 14.
  • the coupon itself may take any shape including curved straight, flat or any other shape.
  • it may be formed by any known method or technology including selective laser melting.
  • the component 2 is a turbine blade 4 that includes a measurement channel 18 fluidly connected to a fitted coupon 8 and sensor 14.
  • a property of the working fluid such as pressure
  • the measurement channel 18 with a first end opening to the working fluid and a second end in fluid contact with the sensor 14 may be formed prior to the installation of the coupon 8, for example during manufacture of the blade using a techniques including but not limited to Selective Laser Melting, casting, and drilling.
  • the cavity 6 for fitting and joining the coupon 8 is first formed in the component 2.
  • Methods for forming the cavity include machining, electro-chemical processes such as milling, die sinking, or direct build-up by additive manufacturing of the coupon with cavity,..
  • a cavity 6 is formed in a component 2, a coupon10, fittable within the cavity 6 is formed, a sensor 14 is embedded in or on the coupon 8 and the coupon 8 is fixed into the cavity.
  • the order which the cavity 6 and coupon 8 are formed is not significant.
  • At least part of a surface of the coupon 8 and a surface of the sensor 14 is covered by a coating 12.
