FIRE AND EXPLOSION SUPPRESSION

Title:

FIRE AND EXPLOSION SUPPRESSION

Document Type and Number:

WIPO Patent Application WO2002078788

Kind Code:

A3

Abstract:

A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) or other water mist generating means at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomised mist of very small droplet size is mixed with the pressurised gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged through spreaders (26, 28). Separation of the mist production from the actual discharge of the mist, and the entraining and transporting of the mist between these two stages at high pressure and high velocity, produces an output mist of very small droplet size which is carried by the entraining and transporting high pressure gas into the area to be protected, enabling a total flooding capability.
