This study focuses on two types of hydrogen-gasoline hybrid refueling stations, and a risk assessment study on thermal radiation is carried out with a fire at each hybrid station. One of the hybrid stations has bare hydrogen storage cylinders, and the other has container walls around the cylinders. We calculate radiative flux to the cylinders from the fire occurring at the gasoline refueling machines in each hybrid station. Additionally, we calculate the temperature rise of the cylinders based on the obtained radiative flux. To evaluate a dangerous case for hybrid stations, we calculate the radiative flux and temperature rise using a large scale and high temperature fire. Based on our analysis, we find that the container walls can greatly insulate the radiative flux. Therefore, we show that we are able to keep the temperature of the cylinders below the hazardous temperature of 358 K by installing container walls around them.

这项研究集中于两种类型的氢汽油混合燃料加油站，并且在每个混合燃料站着火的情况下进行了热辐射风险评估研究。混合动力站之一具有裸露的氢气储气瓶，而另一个具有围绕储气瓶的容器壁。我们根据每个混合动力站加油机发生的大火计算出向气缸的辐射通量。另外，我们根据获得的辐射通量计算气缸的温升。为了评估混合站的危险情况，我们使用大规模高温火灾来计算辐射通量和温升。根据我们的分析，我们发现容器壁可以极大地隔离辐射通量。所以，
