Abstract

A new effervescent atomized water mist fire extinguishing equipment was developed by combining the characters of water mist and effervescent atomization. A series of wood crib and gasoline pool fire suppression experiments were performed using the equipment. The fire extinguishment time, temperature and radiation heat flux of the flame were measured, and then the process of putting out different type fire was analyzed. A wood crib fire of 0.6A can be put out in 180 seconds using water mist produced by effervescent atomization equipment. Only 38 seconds was taken to suppress a gasoline fire.
