Filed: 1994-12-22
Abstract: PURPOSE: To extinguish a fire in a sealed and sectioned area by spraying water with the specific mean particle diameter at the specific water spraying density so as to accomplish prevention of the spread of a fire and that to another place. CONSTITUTION: Plural spray nozzle heads 2 are installed downward on a ceiling surface of a sealed and sectioned chamber 1, and a fire is extinguished by filling the sealed and sectioned chamber 1 with sprayed water. In this process, a mean particle diameter of the sprayed water is ranged from 30 to 100μm, while a density of the sprayed water is set to 0.15-0.5liter/min/m<3> . If the mean particle diameter is below 30μm, penetrating force to a fire is weak and sufficient cooling effect is not obtained. If the means particle diameter is 100μm or more, a net water surface area is small and a vaporizing quantity is small, so that oxygen concentration diluting effect is lowered.  When a density of sprayed water is below 0.15liter/min/m<3> , fire extinguishing force is weak, while it is above 0.5liter/min/m<3> , costs are increased according to the increase of the diameter of a pipe.
