Experimental investigation on the performance of the standardized testing method for detonation fl ame arresters

  • Detonation flame arresters are typically used as protection systems in industrial applications to prevent flame transmission from one section of a plant to another after an incidental ignition. Numerous processes in the chemical and petrochemical industry are taking place under non-atmospheric conditions (e.g., increased pressure and/or temperature) in order to optimize the production capabilities. To verify and examine the suitability of detonation flame arresters, a test method originating from the DIN EN ISO 16852 standard, which is mainly based on findings from experiments under atmospheric conditions, is used. In order to improve the reproducibility of detonation tests at high pressures, especially regarding the deflagration to detonation transition, test methods will be analyzed and improved. The main objective of this study is to develop an improved test method for detonation flame arresters, which offers a higher reproducibility and moreover, an applicability underDetonation flame arresters are typically used as protection systems in industrial applications to prevent flame transmission from one section of a plant to another after an incidental ignition.

The main objective of this study is to develop an improved test method for detonation flame arresters, which offers a higher reproducibility and moreover, an applicability under non-atmospheric conditions. Therefore, an interlaboratory comparison on the performance of in-line flame arresters for stable and unstable detonations is jointly conducted by the project partners (PTB, BAM, Braunschweiger Flammenfilter GmbH and IBExU GmbH). The experiments are performed according to the test method regulated in the DIN EN ISO 16852 standard for different pressures before ignition and different explosion groups. Potential ambiguities of the standardized test method that might lead to the differing results at the different institutes are identified from the interlaboratory comparison. Based on these results, an improved test method for detonation flame arresters will be developed, which will ensure a greater safety at process plants while handling combustibles.zeige mehrzeige weniger
