Abstract: A series of vertical fire suppression experiments are conducted using rigid polyurethane (RPU) material of dimensions 60 x 30 x 2 cm in the standard combustion chamber. Four different kinds of water spray fluxes (66.7, 80, 90, 100 ml/min) and two different spray angles (0 degrees and 30 degrees) are used to suppress wind-aided RPU fire. The thermal radiation, carbon monoxide concentration and smoke concentration are measured with water spray being applied or not. The results show that both of the maximum radiation and maximum smoke concentration appear to have minimum values with 90 ml/min water spray flux and 0 degrees water spray angle. In addition, all the obtained values of the maximum radiation, maximum carbon monoxide concentration, extinguishing time and maximum smoke concentration with 0 degrees spray angle are larger than those with 30 degrees spray angle with the same water spray flux. That is, for the same water spray flux, the suppression effect with 30 degrees spray angle is better than that with 0 degrees spray angle. (C) 2015 Published by Elsevier Inc.
