Abstract
Burning behaviors of the spray bitumen mixture were investigated experimentally. Investigations of the suppression methods of this typical kind of fire were also included. The characteristics of water mist were tested by LDV/APV system. Temperatures were measured by thermocouples and the internal structure was observed by Thermography. Results indicated that the highest temperature was measured in the core of the spray. At the lower pressure ratio (pw/pf≤2. 65), the water mist envelops the spray fire into a ball of fire. At the higher pressure ratio (pw/pf>2. 65), the water mist suppressed the spray fire within a short time. The higher pressure water mist demonstrated higher efficiency for the suppression of spray fires.
