Numerical Simulation of Liquefied Propane Gas Storage Tanks Full-Size Pool Fire Based on FDS

Abstract

This paper takes a 50000 m3 liquefied petroleum gas storage tank in a chemical company in Tianjin for an example, and adopts the fire simulation software FDS to make numerical simulation for the whole-area pool fire accident in the liquefied propane gas tank. The variation of flame and the flue gas in the combustion process of pool fire is obtained from the simulation. The simulation results show that flame shape, smoke production rate and thermal radiation intensity is small in the early pool fire, and significantly increases with the development of combustion process, finally maintains in a relatively stable state.
