Calculation and Comparison of Parameters during Fire in Large Capacity Crude Oil Storage Tanks

The heat release rate during a fire is an initial parameter for calculating average flame height. Average flame height is essential for subsequent calculations of heat flow density and also for setting separation distances. The article calculates and compares the values of these two basic parameters in a fire in three real, existing large - capacity tanks for the storage of crude oil. The stated cal culations are for the two most difficult scenarios of five possible fire scenarios for above ground double - walled storage tanks with floating roofs. The calculations showed that increasing the diameter of the tank increases the flame height, but not in pro portion, and above a certain threshold diameter of the tank remains virtually constant.
