Abstract

An injection system for polymer gel emulsion is powered to cause polymer gel emulsion to be injected into high energy water entering a scooping intake, such as that on a firefighting aircraft. To energize the polymer gel emulsion, an accumulator is interposed between a polymer gel emulsion injection line and the water scooping intake. High energy water is routed to one side of the accumulator where this high energy water acts on the accumulator to move a movable element within the accumulator which pressurizes and expels polymer gel emulsion into the polymer gel emulsion injection line for injection of the polymer gel emulsion through a junction and into a mixed supply line of water and polymer gel emulsion downstream of a junction. The mixed polymer gel emulsion and water are routed to a tank for storage until ready for use.
