Abstract

In order to improve fire emergency response ability of large floating roof tanks, three annular pool fire tests are conducted by using ethanol. Firstly, the mass loss rate, axial temperature and flame distribution of pool fires were measured. Then a comparison was made between the measured temperature and the calculation from traditional plume models. Finally, the calculation model of plume axis temperature was modified. The results show that the burning rate of annular pool fire increases by 8. 1% and 48. 4% compared with that in circular pool fire(0. 62 g/ s) as it comes to fusion combustion stage; the axial flame temperature increases first and then decreases, resulting in a maximum temperature between 20%-60% of flame height, and the calculated values obtained from the modified model are more consistent with the measured temperature; the thermal steam flow generated by the fusion flame in infrared camera will increase the hazards of thermal diffusion to external conditions. © 2019 China Safety Science Journal
