Abstract
An atomizing nozzle and fixed clean agent fire suppression system. The system stores gas fire suppressant in a liquefied state separate from propellant gas. Upon demand, the propellant charges the gas fire suppressant to provide a piston flow system that pushes the gas fire suppressant in the liquid state through a pipe network to the protected area of a building. The system includes a plurality of atomizing nozzles for atomizing the gas fire suppressant where it more easily vaporizes. Each atomizing nozzle comprises a nozzle body and a deflector body secured together in fixed relation. A conical flow passage is formed between the nozzle body and deflector body. The conical flow passage extends radially outward to a circumferential outlet slot that spreads the liquid clean agent out into a thin liquid conical fan that breaks up into droplets and atomizes quickly.
