Abstract
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.
