Abstract:
1. A fire suppression system, comprising: a source of pressurized gas; a source of pressurized liquid; at least one emitter for atomizing and discharging said liquid entrained in said gas on a fire; a gas conduit providing fluid communication between said pressurized gas source and said emitter; a piping network, separate from said gas conduit, said piping network providing fluid communication between said pressurized liquid source and said emitter; a first valve in said gas conduit controlling pressure and flow rate of said gas to said emitter; a second valve in said piping network controlling pressure and flow rate of said liquid to said emitter; a pressure transducer measuring pressure within said gas conduit; a fire detection device positioned proximate to said emitter; said emitter comprising: a nozzle having an inlet and an outlet and an unobstructed bore therebetween, said outlet having a diameter, said inlet being connected in fluid communication with said first valve; a duct, separate from said nozzle and connected in fluid communication with said second valve, said duct having an exit orifice separate from and positioned adjacent to said nozzle outlet; a deflector surface positioned facing said nozzle outlet, said deflector surface being positioned in spaced relation to said nozzle outlet and having a first surface portion comprising a flat surface oriented substantially perpendicular to a gas flow from said nozzle and a second surface portion comprising an angled surface surrounding said flat surface, said flat surface having a minimum diameter approximately equal to said outlet diameter; a closed end cavity positioned within said deflector surface and surrounded by said flat surface; and a control system in communication with said first and second valves, said pressure transducer and said fire detection device, said control system receiving signals from said pressure transducer and said fire detection device and opening said valves in response to a signal indicative of a fire from said fire detection device.
