The present application thus provides a compressor wash system for use about a bellmouth of a compressor of a gas turbine engine. The compressor wash system may include a bellmouth wash nozzle positioned about the bellmouth of the compressor and a wash door assembly positioned about a lower half of the bellmouth such that the wash door assembly may be closed when the bellmouth wash nozzle is activated.

A spray head assembly comprising a body configured to receive a supply of fluid and a face in fluid communication with the body, the face having a plurality of nozzles arranged in a non-linear pattern for directing the fluid from the spray head, wherein the plurality of nozzles are configured to direct the fluid flow to form a wedge-shaped spray pattern between the face and a focal region at a focal length from the spray head, and wherein the spray pattern forms a linear spray arrangement in the focal region.

A nozzle lance for exhaust gas treatment, a combustion plant with nozzle lances for exhaust gas treatment and a method for exhaust gas treatment in a combustion plant are proposed, wherein an admixing fluid is admixed to the active fluid in the nozzle lance and atomized via three nozzles.

A steam atomizing liquid spraying system which in the preferred embodiment includes a spray nozzle assembly having a central liquid passageway for coupling to a liquid supply and a plurality of spray nozzles each removably mounted in the nozzle body and having a respective central steam passage communicating with a steam supply. The spray nozzles each further have a plurality of circumferentially spaced liquid accelerating passages that communicate with a respective angled passage of the nozzle body which in turn communicates with the central liquid supply passageway for directing liquid into the central steam passage of the spray nozzle for interaction with steam directed through the central steam passage and atomization of liquid discharging from the spray nozzle. In an alternative embodiment, a single spray nozzle insert is utilized.

An electrostatic sprayer operable at high flow rates and low pressures particularly suitable for spray drying. The sprayer includes an elongated body having a downstream spray nozzle assembly through which electrically charged liquid is directed via a central feed tube within the nozzle body and atomizing air is supplied via an annular passage about the liquid feed tube. In one embodiment, the nozzle assembly is an external mix cluster head spray nozzle assembly having a plurality of circumferentially spaced metallic spray tips. In another embodiment, the spray nozzle is an internal mix nozzle assembly having a spray tip with an internal mixing chamber for atomizing liquid prior to discharge.

The present invention discloses an automatic adhesive spraying control system for a progressive die of a motor lamination core of a new energy vehicle. During stamping of the progressive die, a nozzle is moved downward under the effect of downward movement of a steel strip, such that a gap is defined between a side wall of a conical head of the nozzle and an inner side wall of a first conical hole of the nozzle. An ejecting hole ejects an adhesive subjected to air pressure regulation, such that different gas pressures can be used for adhesive spots and adhesive channels at different positions.

A spray head includes a first plurality of nozzles for emitting water in a first spray pattern and a second plurality of nozzles for emitting the water in a second spray pattern. In at least one mode of operation, the water is emitted from both the first plurality of nozzles and the second plurality of nozzles with the second spray pattern being at least partially encompassed within the first spray pattern; and wherein at least one of the first or second spray pattern is a hyperboloidal shape.
