Study on Extinguishment of Fire by Spray (2nd Report)

Abstract

In previous report, when the writer carried out the extinguishment test on kerosene fire by water spray containing emulsifier, the efficiency of extinguishment was influenced in larger degree by the pressure of spray discharge than emulsifier.
Then, extinguishment tests on kerosene fire were held varying the pressure of spray discharge. If the minimum quantity of spray discharge that extinguishes kerosene fire in time of 1～2 seconds is selected under the condition that the pressure of spray discharge is constant, the efficiency of extinguishment becomes maximum.
At the discharge pressure of spray more than 15kg/cm², there is not much change in the time required for extinguishment of fire.
