A misting fan system includes a fan and a mister positioned above the fan. The fan includes a motor and a plurality of fan blades operably coupled thereto. Each of the fan blades comprises a base member and a paddle member mated to the base member, and each paddle member comprises an upper surface and a lower surface. A hydrophobic coating may be applied to at least one of the upper surface and the lower surface of the paddle member of at least one of the plurality of fan blades.

A method of cleaning deposited solid material from a fouled portion of a gas compressor whilst the gas compressor is in situ in a natural gas processing system is provided. The method comprises the steps of supplying a liquid cleaning agent to a gas inlet of the gas compressor, the liquid cleaning agent being capable of removing the deposited solid material; passing the liquid cleaning agent through the gas compressor to a gas outlet of the gas compressor, wherein at least a portion of the cleaning agent remains in a liquid state as it passes through the fouled portion of the gas compressor; and recovering a fluid containing removed material that is output from the gas compressor so as to prevent the removed material reaching one or more gas processing stages of the gas processing system downstream of the gas compressor.

A cooling device includes a cover, a trough connected to the cover, and a fan circulating air that is received from sides of the cooling device. The area above the fan is enclosed by the cover. The cooling device also includes a pump for delivering liquid to one or more pads located in the trough. The cooling device also includes a sensor that controls operating of the fan and the pump.

A volatile material delivery device may include a hub having one or more vanes coupled to the hub. A porous material may be coupled to the hub. Optionally, the porous material may be coupled directly to the hub and/or may be coupled indirectly to the hub by being coupled to a vane that is coupled to the hub. A volatile material may be in communication with the porous material so that the volatile material may pass through the porous material. Rotation of the hub may result in rotation of the vanes and the porous material. Additionally, rotation of the porous material may cause or increase the release of volatile material, and rotation of the vanes may generate an air current which may move across the porous material so that the volatile material is distributed into the environment in the air current generated by the vanes.

A rotating plate misting fan (RPMF) is capable of delivering cooling to industrial environments including loading bays for docked trailers. The RPMF includes a rotating plate assembly configured to eliminate or minimize water collection in the environment area.

A system for cleaning a gas turbine engine may generally include a wash stand having a base frame and a plurality of fluid injection nozzles configured to be supported by the base frame relative to the gas turbine engine. The nozzles may be configured to inject a cleaning fluid through an inlet of the fan casing of the engine as the fan blades are being rotated in a rotational direction such that the cleaning fluid is directed past the rotating fan blades and into a compressor inlet of the engine. Additionally, each nozzle may be oriented at a positive tangential angle defined relative to the rotational direction of the plurality of fan blades. The system may also include a fluid source in flow communication with the wash stand for supplying the cleaning fluid to the plurality of fluid injection nozzles.

A pump arrangement for powering a pump in providing a controlled volume of water to a drip nozzle in a drip-feed humidifier. The pump arrangement includes: a pump having a solenoid; a processing unit; and a power supply electrically connected to the solenoid via a switch which is controlled by the processing unit. The power supply is structured to supply power to the solenoid via the switch. The processing unit is programmed to modulate the power provided to the solenoid via the switch such that the power is supplied to the solenoid according to a power profile for each actuation of the solenoid. The power profile includes: an initial portion which increases at a first overall rate, an intermediate portion which increases at a second overall rate different than the first overall rate, and a final portion which decreases at a third overall rate.

A sealing system of a turbomachine for sealing a rotor of the turbomachine relative to a stator of the turbomachine, having a rotor-side component rotating together with the rotor, a stator-side component that is stationary together with the stator, and a dry gas seal, which includes a rotor-side sealing component and a stator-side sealing component compressed via a spring element forming a sealing gap, and a cleaning device, via which detergent is conducted in the direction of the spring element for cleaning the same and/or in the direction of the sealing gap for cleaning the same.

A packed tower includes a packed tower housing having an inlet for receiving an effluent stream; an outlet for venting the effluent stream; a packed substrate housed within the packed tower housing between the inlet and the outlet, the packed substrate being configured to entrain at least some of particles from a fluid as the effluent stream flows therethrough; and a fan housed within the packed tower housing, the fan being configured to propel the effluent stream from the inlet towards the outlet and to remove at least some of the particles from the fluid. The fan helps to generate a negative pressure to draw the effluent stream into the packed tower and through the packed substrate, which reduces the back pressure improves the flow of effluent stream through the packed tower and upstream abatement apparatus and helps to improve the removal of particles from within the effluent stream.
