Large-scale tests to investigate the consequences of exposing cryogenic storage vessels containing liquid hydrogen to a fire load

  • Large Scale Experiments have been performed to determine whether a storage vessel containing liquid hydrogen (LH2) and caught in a fire engulfing the vessel can result in a BLEVE (Boiling Liquid Expanding Vapour Explosion) and if so its consequences. The tests were performed at the Test Site Technical Safety of the Bundesanstalt für Materialforschung und –prüfung (BAM) in Germany at the Hydrogen Test Area (H2TA) within a research cooperation between BAM and Gexcon as part of the SH2IFT program. Three tests were performed using double-walled vacuum insulated vessels of 1 m3 volume. The cylindrical Vessels differed in orientation (horizontal or vertical) and the insulation material used (perlite or multi-layer insulation (MLI)). The degree of filling of the vessels was approximately 35-40 % in each of the tests performed. The fire load was provided by a propane fed burner-system positioned under the storage vessel and designed to give a homogeneous fire load.

The degree of filling of the vessels was approximately 35-40 % in each of the tests performed. The fire load was provided by a propane fed burner-system positioned under the storage vessel and designed to give a homogeneous fire load. The conditions in the vessel (temperatures and pressure) as well as external effects (heat radiation, blast waves, flame ball development and fragmentation) were measured. All vessels were equipped with K-type thermocouples at several locations at the inner and outer vessel shell. The pressure inside the inner vessel and in the space between the inner and outer vessels (vacuum pressure) was measured. Bolometers were used to measure the heat radiation generated by both the propane fire and that generated by a possible fireball/BLEVE. To measure blast generated by the vessel burst/BLEVEs blast pencils were positioned at up to three locations. Further several cameras were used to monitor the events: normal cameras, infrared (IR)-cameras, high-speed cameras also on board of an UAV. Two of these vessels, a horizontal and a vertical vessel both insulated with perlite withstood the fire loading for 1 hour 20 minutes and 4 hours respectively without catastrophic failure. A horizontal vessel insulated with MLI failed by bursting after 1 hour and 6 minutes resulting in a fireball, fragments, and blast wave.zeige mehrzeige weniger
