FINE WATER MIST SYSTEM FOR REPLACEMENT OF HALON 1301 FIRE EXTINGUISHER SYSTEMS
Agency / Branch:
DOD / USAF
U.S. production of Halons will decrease from 28 million lbs in 1988 to zero in 1995 to meet the U.S. commitments to the Montreal Protocol. A major use of Halon 1301 is as a fire suppression flooding agent. The use of fine water mists from two-fluid atomizing nozzles is proposed as a replacement for Halon 1301 fire suppression systems, especially for Class B fuel fires. The optimum droplet size and atomizer water flow rate will be determined in the Phase I research. Several candidate atomizers will be tested against a standard n-heptane fire in a test chamber. Spray droplet size and water application rates will be varied over a range determined by modeling of the evaporation rate of the droplets. Requirements for a fire suppression atomizer nozzle will be prepared, based on the test results. In Phase II, a prototype fire suppression system will be designed, built, and tested on typical Air Force Class B fires. A specification for fine water mist fire suppression systems to replace existing Halon 1301 systems will be based on these Phase II tests.
