烟草火灾危害后果定量评价研究
Quantitative Evaluation Research of Harmful Consequences of Tobacco Fire
摘要
Abstract
In order to evaluate the fire hazard of flue gas in tobacco warehouse,based on models of visibility, heat,FED and N-GAS,TVH (Toxicity,Visibility,Heat)model is proposed.Using the method of PyroSim soft-ware simulation,taking a fire tobacco warehouse as the prototype,the virtual fire scene close to the real is built. Through simulating the movement law of the smoke and the variation curve that hazard evaluation factors of flue gas change with time,it is concluded that the effect of flue gas of different position is different.According to the flue gas hazard index the three models quantitative calculate,the conclusion heat is an important cause of casualties is analyzed.Considered the effect of heat and visibility,the evaluation hazard of TVH model is more comprehensive than that of N-GAS and FED model.Finally,the application of TVH model is put forward.关键词
