DUAL EXTINGUISHMENT FIRE SUPPRESSION SYSTEM USING HIGH VELOCITY LOW PRESSURE EMITTERS

摘要

A fire suppression system is disclosed. The system includes a gaseous ext inguishing agent and a liquid extinguishing agent. At least one emitter is i n fluid communication with the liquid and gas. The emitter is used to establ ish a gas stream, atomize and entrain the liquid into the gas stream and dis charge the resulting liquid-gas stream onto the fire. A method of operating the system is also disclosed. The method includes establishing a gas stream having first and second shock fronts using the emitter, atomizing and entrai ning the liquid with the gas at one of the two shock fronts to form a liquid -gas stream, and discharging the stream onto the fire. The method also inclu des creating a plurality of shock diamonds in the liquid-gas stream discharg ed from the emitter.
