Abstract: The present application provides a fuel conditioning system for delivering a flow of fuel to a nozzle in a gas turbine engine. The fuel conditioning system may include a fuel compressor to increase the pressure of the flow of fuel, a pressure reduction valve to decrease the pressure of the flow of fuel, and a heater downstream of the pressure reduction valve. The pressure reduction valve may include a rotary control valve.

Abstract: A system includes an industrial machine that includes a motor and a motor bearing. The system also includes multiple acoustic sensors disposed adjacent the industrial machine. The system further includes multiple other sensors disposed adjacent the industrial machine. The system even further includes a controller programmed to receive noise signals representative of a noise made by the motor bearing acquired by the multiple acoustic sensors, to receive signals representative of operational conditions of the industrial machine, to analyze the noise signals to determine characteristics of the noise, to analyze the characteristics of the noise utilizing the operational conditions, to compare the characteristics of the noise to a plurality of models associated with different noises made by the motor bearing that are associated with a particular abnormal operation, and to select a model from the plurality of models that matches the characteristics of the noise.
