ABSTRACT:
A nozzle for discharging vaporizable liquid fire suppressant material tow a flame area to be suppressed. A nozzle includes internal mechanism for forcing an insulator shroud around the liquid fire suppressant while the suppressant is still within the nozzle. The shroud insulates the liquid material while the liquid stream is traveling toward the target flame, thereby preventing premature flashing or vaporization of the liquid. A particular aim of the invention is to increase the penetration distance, i.e., travel distance before the liquid is dissipated.
