Experimental Study on Thermal Response Mechanism of Spraying Coated Liquefied Petroleum Gas Storage Tank under Pool Fire Environments
The inorganic water-based non-expanding fireproof coating was taked as the research object,and the coating thickness as the main influencing factor,the thermal response tests of liquefied pertoleum gas tanks were conducted in a pool fire environment.The wall temperature response,damage time,and failure mode of storage tanks after spray fireproof coatings were studied in pool fire environments.The results show that the inorganic water-based non-expansion fireproof coatings have a significant delayed effect on the explosion time of storage tanks under fire action.For civilian liquefied petroleum gas storage tanks,when the filling level is the same,the tank which coating thickness is 2 cm is 6.91 times that of bare tanks in a pool fire environment,the tank which coating thickness is 3 cm is 1.20 times that of the tank which coating thickness is 2 cm,and the tank which coating thickness is 4 cm is 1.05 times that of the tank which coating thickness is 3 cm.The delayed effect of increasing coating thickness on the damage time of storage tanks in a pool fire environment gradually decreases,so it is suggest that to the coating thickness of 3 cm is suitable for storage tank.The research results have certain significance for the safety protection application of storage tanks in a pool fire environment and the study of fireproof coating.
