摘要:现代火灾科学研究表明,材料的热释放速率是决定火灾发展的基本参数之一.它不仅对火灾的发展起着决定性作用,而且也显著地影响其它诸多火灾灾害因素的变化.本文在受限空间内,进行不同二茂铁体积分数作用下的油池火熄灭实验,研究二茂铁与油池火相互作用时其动态发展过程.采用基于O2消耗原理的热释放速率测试方法,研究了二茂铁作用下的油池火热释放速率特性曲线,同时分析了烟气中O2体积分数和CO体积分数变化.经过实验分析得出:二茂铁对油池火有很好的抑制作用,且随着二茂铁体积分数的增加,油池火的热释放速率而明显降低.

Heat release rate study of pool fire characteristics interacted with ferrocene

Abstract:It is shown that the heat release rate is one of the most essential parameter for combustion process in modern research.The heat release rate not only plays a decisive role in the development process of the fire but also significantly affects many other fire factors change.In this paper, the pool fire extinguished examinations under different concentrations of ferrocene are done in the restricted space.The heat release rate of the pool fire changes is studied and the changes curve of oxygen and carbon monoxide concentration in the flue gas under ferrocene are analysed.The results show that ferrocene had a good inhibitory effect on the pool fire, which with the increasing concentration of ferrocene, the heat release rate of pool fire was markedly lower.
