Abstract
A study was conducted in which pressurized propane tanks were subjected to fire in order to examine how the pressure relief valve (PRV) behaved under various blowdown and fire conditions. During the summers of 2000, 2001 and 2002, a total of 13 controlled tests were carried out on 1890 litre propane tanks which had pressure transducers, lading and wall thermocouples, and an instrumented flow nozzle. The pressure of the PRV was controlled by computer. The tank was heated with high momentum liquid propane torches. The impact of the blowdown and fire conditions was determined by examining the nature of the failure, the time to failure, and a thermohydraulic response to the tank lading. Results indicated that both the behaviour of the PRV blowdown and fire conditions impact the outcome of the fire impingement. An increase in the blowdown was found to delay failure and resulted in a lower fill level and stored energy at failure, therefore the hazard was lessened. It was recommended that the PRV blowdown should be set as large as possible, and the PRV opening pressure should be set as low as possible.15 refs., 15 tabs., 58 figs., 10 appendices.
