    Abstract
  • Fire extinguishing by explosive water mists is a new method with high efficiency and rapid fire-extinguishing performance.In order to study the process of explosive water mists acting on oil fire, a CCD camera, a fine thermocouple and an infrared thermometer were used to capture the images of fire extinguishing by explosive water mists and the temperature variation during extinguishing process.The experimental results show that the temperature drops sharply while the explosive water mists impact on the oil-fire surface, and the fall time is in accord with the fire extinguishing duration from CCD images.Also, when the water bag is placed 1.0 m above the oil pan with 3 kg water and 2.02 g explosive, the extinguishing duration time is about 200 ms.A fine thermocouple can be used as an accurate measuring device to represent the temperature variation of the extinguishing process, while an infrared thermometer is a good auxiliary means to qualitatively investigate the temperature change of extinguishing process.
