Application of 2-bromo-3,3,3-trifluoropropene (BTP) with water mist in suppressing deep seated wood crib fires was reported in this paper. Performance of the combination of the two clean fire suppressants was examined by laboratory scale experiments and compared with water mist and BTP used alone. Results showed that coupling of water mist with BTP could extinguish the wood crib fires with high efficiency, in which BTP discharged first could fast extinguish the flame, and the following water mist could cool the wood surface and stop glowing combustion. As a result, a complete fire extinguishment without re-strike was achieved in short time. Furthermore, hydrogen fluoride (HF) acid gas produced in the suppression process was acceptable for the use of water mist in conjunction with BTP.

“…The maximum flame temperature of all the three tests should be above 700 o C as reported in the literature [18]. Recorded temperatures for SMW-1 to SMW-3 were lower than 460 o C. A possible reason is that these thermocouples were not located within the flame area with higher temperature.…”

“…Experimental data indicated how the installed systems perform in an open kitchen fire [17]. Improvements through the use of new gas-solid composite particles developed recently [18] were evaluated. Appropriate system designs [7] for high-level fire hazards can then be recommended to prevent kitchen fire growth.…”

Experiments with burning cooking oil in open kitchen fires are reported in this paper. Heat release rate, flame temperature, burning duration and heat fluxes of cooking oil fires were measured. Performances of water mist and gas-solid composite dry powders in suppressing cooking oil fires were evaluated by experiments. Reduction in gas temperature distributions, changes in heat fluxes and suppression time were then measured. Experimental data will provide necessary information for hazard assessment of open kitchen in the residential units of tall buildings.

Summary The fluoroprotein foam is one of the most widely used fire suppressants for its low cost, low toxicity and biodegradability. However, its fire extinguishing performance is limited. In this article, fluoroprotein foam was combined with a clean and degradable fire suppressant of 2‐bromo‐3,3,3‐trifluoropropene (BTP) to improve its fire extinguishing efficiency. Laboratory scale suppression experiments on gasoline pool fires were conducted in a 27 m3 confined space. An optimized volume flow ratio of air to foam solution was found out first to acquire fluoroprotein foam with best fire extinguishing efficiency; then varied amounts of BTP were added to the foam at the optimal flow ratio for performance examination. Results demonstrated: at the optimized volume flow ratio of air to foam solution of 9 and the volume flow ratio of BTP to foam solution of 3.75%, a superior fire extinguishing performance was achieved with the fire extinguishing time reduced by 43% in comparison to that without any BTP added. The fire suppression mechanism of the foam with BTP additive was discussed based on established fire suppression theories and experimental results. Copyright © 2014 John Wiley & Sons, Ltd.
