Research on the Initial Features and Spreading Rules of Large Scale Oil Fire

The initial features of large scale oil fires were studied through combustion experiments in oil basins. Four basins were prepared, the diameters of two of them were 2.5m, and another two were 2m. Oil in the basins was ignited simultaneously, and the experiments were conducted twice. The thermal radiation, temperature distribution and components of pollutants were detected and analyzed. Then, some initial features and instructive rules of large scale oil fire disasters were concluded. Known from the experiments, the temperature is high in center areas and low around, in the vertical direction the temperature is high both in upper part and bottom and low in the middle. In addition, the density values of gas pollutants sampled during the experiments can reach to several hundred times of the standard values.
