A high efficiency phase change nozzle (16) has a body (19) with primary orifices (29), a pilot nozzle (20) extends upstream from the body and has a pilot orifice (35) and central cavity (36) through which a pilot flow of liquid is flashed to the solid state, cooling the pilot nozzle, thereby precooling the liquid before it flows through the primary orifices. An exit nozzle (21), in conjunction with a housing (17), assists in continuing the phase change of the mixture exiting the primary orifices and with dispersing the mixture into the downstream cavity (43). |
