Abstract
The pool fire with characteristics of high temperature and high radiation intensity, is serious accident in chemical companies, but the research for pool fire of large tank area is relatively scarce. Taking a large crude oil storage tank area for an instance, this paper focuses on large-scale pool fire, and the flame height and heat flux was calculated and analyzed considering the influence of wind speed. Based on the theory of the pool fire, the fire characteristics under different wind speed (V = 0 ~ 20m / s) are simulated and calculated with simulation software FDS. Analyzing and contrasting the calculation, it shows that: Hotfijzer model and Pritchard-Binding model is applicable to the calculation for flame angle and height of large-scale hydrocarbon pool fire, when the wind speed is 20m/s, the radius of death, serious injury and minor injury is respectively 63.8m, 73.4m, 93.4m at down wind, and the adjacent tanks and fire dike will soon be ruined completely by the thermal radiation, when the wind speed is faster than 4m/s, the pumping station will be damaged in the long period of heat radiation, and the metering plant and office, the adjacent road and power lines outside the storage house will have only a slight effect.
