Experimental Study on Pressure Relief of Gas Explosions in Large Vessels

The study aims to contribute insights into the design and implementation of pressure relief systems in industrial applications, presenting an experimental study of pressure relief during gas explosions within a 4.4 m³ vented vessel. The experiments focus on evaluating various combustible gases, specifically ammonia, methane, propane, ethylene, and hydrogen, five model combustibles representing different ranges of laminar burning velocity. A series of burst discs with varying diameters and static activation pressures were tested to assess their impact on the reduced explosion pressure. The experimental results were compared against two low-order models from existing literature, providing a validation framework for these theoretical approaches.
