Study on application tests of mobile water mist fire suppression device
Water mist extinguishing technology has drawn great attention of fire service in recent years, and gained widely applications in fire departments. In this paper, mechanism of fire suppression, types and characteristics of mobile water mist devices have been analyzed. Drop diameter measurements and contrast tests of fire suppression by water mist device and water spray nozzle at almost same flow have been carried out The test results showed that when in open space, mobile water mist device could control class A fires, but more suitable for the surface fire rather than deep seated solid materials fire, especially smoldering fire. In open spaces, small scale gasoline fire could be put out with longer time by the devices with plain water. With the enlargement of fire scale, gasoline fire could not be put out. However, when using foam additive, the time of fire suppression and water consumption would be greatly reduced, the ability of fire suppression would be greatly enhanced. As for diesel fuel fire, mobile water mist device has good fire suppression ability and is water-efficient.
