A hazardous gas monitoring system is provided. The hazardous gas monitoring system includes a panel including multiple sensing lines. Each sensing line is configured to receive and monitor an air sample. Each sensing line includes a water separator to remove condensed moisture, a coalescing filter disposed downstream of the water separator, and a flow and gas monitoring system disposed downstream of the coalescing filter. The hazardous gas monitoring system may be used to monitor the presence of hazardous gases within an enclosure, such as an enclosure for a turbomachine.

Hazardous gas monitoring system

A leak detection system is provided with a first window configured to mount at a first opening in a first wall portion in an enclosure (e.g., for a gas turbine engine or other equipment in a power plant). The leak detection system includes a leak sensor configured to transmit a beam through the first window and an interior of the enclosure to obtain sensor feedback. The leak detection system includes a controller configured to evaluate the sensor feedback to monitor for a leak of a hazardous fluid in the enclosure.

Leak detection system and method

An inlet bleed heat (IBH) system for use in a turbine engine including a silencer assembly. The inlet bleed heat (IBH) system includes a feed pipe for delivering compressor discharge air. The feed pipe includes a plurality of orifices along at least a portion of a length of the feed pipe, and each orifice of the plurality of orifices extends through a wall of the feed pipe for allowing the compressor discharge air to exit the feed pipe. The system also includes a heat shielding component that extends across the feed pipe, wherein the heat shielding component is configured to reduce heat transfer between the feed pipe and the silencer assembly of the turbine engine.

A liquid injection apparatus for use with a compressor having a rotor shaft and a casing part is provided. The liquid injection apparatus includes at least one conduit and at least one nozzle coupled to the conduit(s). The liquid injection apparatus is panel-shaped and has a first panel segment, a second panel segment, and at least one of: a passage defined between the first panel segment and the second panel segment, the passage sized to receive at least one of the rotor shaft and the casing part; and a third panel segment positioned between the first panel segment and the second panel segment. The third panel segment is at least in part detachable from the first panel segment and/or the second panel segment for receiving at least one of the rotor shaft and the casing part between the first panel segment and the second panel segment.

A system includes an inlet duct disposed about an inlet axis, wherein the inlet duct is configured to direct an airflow along the inlet axis to a compressor inlet. The inlet includes an inlet heating system and a heating portion having a longitudinal axis that is substantially perpendicular to the inlet axis. The inlet heating system includes a first conduit substantially parallel to the longitudinal axis that is configured to distribute a heated fluid directly to the airflow via a first set of openings of a first end zone of the first conduit and a second set of openings of a second zone of the first conduit. The first end zone is configured to receive the heated fluid from a heating source, the second zone is coupled to the first end zone, and the second zone is configured to receive the heated fluid from the first end zone.

The present application provides a gas turbine engine. The gas turbine engine may include a compressor and an inlet air system positioned upstream of the compressor. The inlet air system may include a wetted media pad for evaporative cooling. The wetted media pad may include a contoured configuration.

Contoured evaporative cooling medium

A silencer duct that may be part of, for example, a turbomachine inlet and may include a duct body, and a silencer element extending axially through the duct body. A first portion of a coupler may extend axially from a first side of the duct body. A second portion of a coupler may extend axially from a second side of the duct body. At least one of the first portion of the coupler and the second portion of the coupler are configured to couple to at least one of an adjacent silencer duct and an inlet.

Silencer duct having silencing element and couplers

A system includes a silencer baffle which mounts in a fluid conduit along a fluid flow path, where the silencer baffle includes a plurality of baffle sections. At least two baffle sections of the plurality of baffle sections couple together via mating interlock structures, and at least one baffle section of the plurality of baffle sections has first and second baffle portions which couple together via mating joints.

The present application provides a method of evaluating media effectiveness in a gas turbine engine. The method may include the steps of receiving a baseline media effectiveness rating, receiving a media replacement cost, receiving a number of operating parameters from a number of sensors, based at least in part on the operating parameters and the baseline media effectiveness rating, determining a media effectiveness model, based at least in part of the media effectiveness model, determining a loss in evaporative benefit cost over time, determining a time t when the loss in evaporative benefit cost exceeds the media replacement cost, and scheduling media replacement at time t.
