Fire Safety Assessment on Fully Closed Renovation for Large Coal Yard
Aiming at the problem that the floor area is oversized resulted from the environment protection requirement for the full closure of the existing coal yard,in this paper,the fire safety assessment method was used and relevant cases were re-ferred to optimize the design from the aspects of fire isolation belts,safety exits,and fire facilities. The FDS numerical simu-lation software was utilized to conduct a comprehensive analysis and verification to the fire radiation interactions between va-rious coal piles and the safety of the steel structure. The results show that a fire isolation belt wider than 12 meters can ensure that a coal pile will not be ignited by the adjacent burning coal pile;and that the critical temperature for the steel structure failure can reach in only local areas which are right above the fire source and where the space height is relatively low. It is suggested to take fireproofing measures for the load-bearing members of the steel structure that are situated in proximity to the coal pile and have lower space height. The assessment findings can provide references for similar scenarios.
