Analysis and Application of Radius Calculation Model for Boilover in Crude Oil Tank Fire

Abstract:

With the development of oil storage tank is towards large-scale, boilover is becoming a greater threat to surroundings. The main damage form of boilover is high-temperature thermal radiation and boil-over in oil tank fires. Among them, boil over can cause great casualties and property losses, and easy to cause the disaster spread. This article first analyzes the influence factors of boilover and the intensity, then further creates radius calculation model for boilover. By calculating and analyzing the boilover radius of tank with different sizes and oils stored, the accuracy of model is verified. The results also indicate that the model is effective and the calculating error is fairly small when the tank diameter is less than 10m, otherwise is suitable for simple estimate only. The influence of water content in oil and the viscosity on boilover radius is non-linear, and there is a maximum.
