Abstract: A system includes an acoustic monitoring, analysis, and diagnostic system having a processor. The processor is configured to receive NF noise signals from a near field (NF) microphone array, the NF microphone array measures noises from a power generation system in a NF. The processor is configured to receive FF noise signals from a far field (FF) microphone array, the FF microphone array measures noises from a power generation system in a FF. The processor is configured to derive NF and FF noise measurements based on the signals and to synchronize the NF and FF noise measurements to create synchronized NF and FF noise data. The processor is configured to analyze the synchronized NF and FF noise data to create a NF and an FF noise signature. The processor is configured to diagnose root causes of noises generated from the power generation system and to report the root causes.

Abstract: An inlet air filtration unit for a gas turbine includes an inlet filter house having an upstream surface through which air is ingested. A plurality of weather hoods is secured to the upstream surface. A wave-generating system is installed on or proximate to the plurality of weather hoods, the wave-generating system emitting waves that deter pests from the inlet filter house. A method of deterring pests from entering an inlet filter house of an inlet air filtration system is also provided. The method includes: installing a wave-generating system proximate to or on a weather hood on an upstream surface of the inlet filter house; and energizing the wave-generating system to produce energy waves across the upstream surface of the inlet filter house.

Abstract: An exhaust stack assembly includes an exhaust stack having an internal surface that defines an interior of the exhaust stack. The exhaust stack is configured to receive exhaust gas from at least one turbomachine component and exhaust the exhaust gas to atmosphere. The exhaust gas assembly further includes a plurality of attenuation assemblies disposed in the interior, each of the plurality of attenuation assemblies including a base substrate generally oriented in the direction of flow of the exhaust gas through the interior, each of the plurality of attenuation assemblies further including a plurality of attenuation modules mounted to the base substrate. Each of the plurality of attenuation modules includes a fiber mesh. The fiber mesh is exposed to the exhaust gas in the interior.
