ABSTRACT:
The performance and throw distance of a nozzle discharging a water stream is enhanced by injecting a liquified gas, suitably liquid nitrogen or liquid carbon dioxide, into the water entering the nozzle at a point sufficently upstream from the nozzle to allow complete vaporization or solidification of the liquified gas before it leaves the nozzle. A second material, that may be a foam producing composition or a particulate solid, may be introduced into the water entering the nozzle simultaneously with the introduction of the liquified gas.
