| Abstract: | In order to reduce the damage and loss caused by the leakage and combustion of oil gathering pipeline, the flow fire and pool fire after oil pipeline leakage are studied based on FERC model and solid flame model. The results show that the extension of ignition time and the increase of leakage pore size can contribute to the development of oil leakage area, thus enhancing the output intensity of radiation heat flux in fire and expanding the scope of dangerous area. Besides, the effect of ignition time on radiation heat flux in flowing fire will be changed by leakage aperture. When the radiation heat flux is 12.5 kW/m2 and the ignition time is 1 000 s and 3 600 s respectively, the dangerous distance difference of the middle hole leakage could reach 12.39 m while that of the large hole leakage is 60.86 m. The influence of the leakage time on the flow fire is limited by the steady burning time of the flow fire, while the pool fire can be continuously affected by the leakage time, leading to the continuous expansion of the danger area. Therefore, the harm degree of pool fire is much higher than that of flowing fire under the same conditions. |
