    Abstract
  • In order to investigate the effect of water mist nozzle to extinguish heptane fire under different injection pressure, a series of experiments were performed in an enclosed compartment of 4.6m×3.3m×4m with a certain type of water mist nozzle under various injection pressure. Thermocouples tree and gas analyzer were used to measure the temperature and oxygen concentration in the flame. The effect of injection pressure on the affectivity of water mist suppressing pan fire was gained, which provides corresponding experimental foundation for designing water mist system, establishing test standard and developing new product of water mist.
