ABSTRACT: Over the past twenty years, China’s oil consumption has increased dramatically, resulting in the birth of a lot of large oil storage area. At the same time, the safety of the oil tank has aroused great attention, especially the oil tank fire which is very difficult to control and put out. One of the important reasons is that high strength thermal radiation of storage tanks may ignite adjacent tanks, easily leading to further development of the fire. In this paper, the numerical simulation method is used to make further study of the problem: from the perspective of danger of oil and oil tank fire as well as the principle and danger of thermal radiation. FDS is used to simulate fire scene and find out the interaction laws of thermal radiation between adjacent tanks. Through studying of the thermal radiation effect on personnel, it is found out that at the height of 1.5m thermal radiation intensity tends to firstly increase and decrease later. At about the 0.55D, it reaches the maximum value. At last, information that is helpful to fireman is summarized from simulation results.
