ABSTRACT:
A fire extinguishing or explosion suppression device comprises a chamber and a nozzle. The nozzle defines a discharge pathway from the chamber. The chamber has an inlet for pressure-driven introduction of a liquid into the chamber. The chamber is shaped so that a gas contained in the chamber before the introduction of the liquid is entrained into the liquid during the pressure driven introduction of the liquid such that a mixture of the liquid and the gas is discharged through the nozzle to create a mist for extinguishing a fire or suppression of an explosion. After the gas has been discharged from the chamber, the nozzle produces a spray having a core of larger liquid droplets with the core being surrounded by smaller liquid droplets.
