62147 - Numerical Simulation on Fire Test of 45 MPa Hydrogen Storage Vessels for Hydrogen Stations 

In recent years, there have been a number of fire and explosion accidents of hydrogen storage vessels in hydrogen stations all over the world. China is vigorously developing the hydrogen fuel cell vehicle industry. At present, more than 80 hydrogen refueling stations have been built, and 1000 hydrogen refueling stations are planned to be built in 2025. In order to study the response law and pressure relief requirements of hydrogen storage vessels in hydrogen refueling stations under fire condition, fire tests of hydrogen storage vessels filled with high pressure hydrogen is planning to carry out. In this paper, numerical simulation of fire tests of hydrogen storage vessels is carried out. The hydrogen storage vessel is a horizontal single-layer seamless structure with working pressure of 45 MPa, wall thickness of 35.4 mm, volume of 205 l and material of 4130X. Propane is used as fuel for fire test. Based on CFD software, the thermal structural response calculation model of the hydrogen storage vessel under fire condition is established. The response law of hydrogen temperature rise and pressure rise in hydrogen storage vessel is analyzed, and the influence of fuel flow rate, filling pressure, ambient temperature and wind speed on the hydrogen storage vessel is studied. The research results provide technical guidance for the subsequent fire test of the hydrogen storage vessel used in hydrogenation stations.
