Control Effect on Diesel Pool Fire by Longitudinal Smoke Discharge and High Pressure Water Mist

Abstract:

The subway tunnel benchmodel(1/3)of small scaled size is established to study fire spread control effect under the combined effect of the longitudinal smoke discharge and water mist. The different working pressure of water mist is opened at the same time with the smoke discharge. The suppression effect of the diesel pool fire is observed and it can be concluded as follows: When the longitudinal smoke is started, it can effectively control the spread of smoke, but the lasted combustion time of fire increased, the sole longitudinal smoke discharge is not the optimum measurement on the control of diesel pool fire. For the diesel pool fire with the surface size of 250mm×200mm, the experiments show that the combination of water mist and longitudinal smoke discharge, which were started simultaneously, are able to control the fire effectively. And the 15MPa water mist is the best on the fire control affection with the combination of smoke discharge.
