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.
Figure 1 shows the simulation structure of pool fire produced by FDS.

Abstract.
Introduction Some manufacturing industries with labor intensive and energy-inefficient characteristic in coastal areas influenced by rising production costs are prompting moves inland in Guangzhou Province, China. 36 or more industrial transfer parks planned and in further development have shown a favorable perspective for industrial structure adjustment and local economic development.
