Application of compressed air foam system in extinguishing oil tank fire and middle layer effect
Firstly,compressed air foam system (CAFS) was briefly introduced.The difference of foams produced from low expansion foam extinguishing system and CAFS were compared according to macro parameters and micro parameters.Secondly,thickness of tank shell,thickness of tank bottom,intensity of water supply and intensity of foam solution supply were determined according to codes.Then oil tank for model test was designed with the help of Auto Computer Aided Design (Auto CAD) and completed using Q345R steel plates.Finally,small-scale model tests were carried out to examine extinguishing effect of CAFS onto oil tank fire.Three conclusions were as follows.The oil tank designed according to codes could endure the flame radiation.CAFS could be applied in extinguishing oil tank fire.The torch-like flame when the fuel level was high and ball-like flame when the fuel level was lower could be explained using theory of middle layer effect.
