Embodiments in accordance with the present disclosure include a meta-stable detergent based foam generating device of a turbine cleaning system includes a manifold configured to receive a liquid detergent and an expansion gas, a gas supply source configured to store the expansion gas, and one or more aerators fluidly coupled with, and between, the gas supply source and the manifold. Each aerator of the one or more aerators comprises an orifice through which the expansion gas enters the manifold, and wherein the orifice of each aerator is sized to enable generation of a meta-stable detergent based foam having bubbles with bubble diameters within a range of 10 microns (3.9×10.sup.−4 inches inches) and 5 millimeters (0.2 inches), having a half-life within a range of 5 minutes and 180 minutes, or a combination thereof.

A foam generating device for a high-pressure water gun has a supporting body defining part of a conduit, which extends along an axis and has a mixing chamber communicating with a lower inlet, and subject, in use, to a vacuum to aspirate a liquid from said lower inlet; the device has a first sleeve which is fitted around one end of the supporting body, is axially fixed, is rotatable and is provided with an end portion carrying a nozzle; such a nozzle defines the outlet of the conduit and is adjustable so as to vary the outgoing flow type between a fan-like jet and a solid stream jet; the device has, in addition, a second sleeve which is coupled to the first sleeve in a fixed axial position and in a rotatable manner and is provided with cams to adjust the nozzle in response to a rotation of the second sleeve with respect to the first sleeve.

A proportioner having a body portion that defines a fluid passage for transporting a fire protection fluid and a foam passage for transporting a foam concentrate. The foam concentrate mixes with the fire protection fluid to form a fire protection solution. The proportioner also includes a restrictor assembly having a restrictor disk and an orifice plate. The orifice plate has an opening for receiving the restrictor disk. The restrictor disk and opening are configured to form an annulus between an outer surface of the restrictor disk and an inner surface of the opening when at least a portion of the restrictor disk is disposed within the opening and the restrictor disk is spaced from the orifice plate. The restrictor assembly is configured to maintain the annulus for a full travel range of the restrictor disk.
