摘要随着哈龙灭火剂的淘汰，气溶胶灭火剂因为有着诸多优点而被广泛关注，但是气溶胶灭火剂较高的燃烧温度制约着它的发展。降低气溶胶灭火剂的燃烧温度，不仅可以增加气溶胶灭火剂的有效载荷，还能有有效的提高其灭火性能。本文先是采用了最小自由能与质量守恒定律相结合的方法，理论研究计算了气溶胶灭火剂在含有不同种类或含量的氧化剂、可燃剂和还原剂时的燃烧温度。然后通过横向和纵向对比，分析氧化剂、可燃剂和粘合剂分别对气溶胶灭火剂燃烧温度的影响。分析结果表明：在一定范围内，气溶胶灭火剂的燃烧温度随着氧化剂含量的增加而升高，随着可燃剂含量的增加而降低；粘合剂含量的增加会导致气溶胶灭火剂燃烧温度的降低。21439

Title Theoretical research of aerosol fire extinguishing agent
combustion temperature influencing factors
Abstract
With the phase-out of halon fire extinguishing agent,Aerosol fire extinguishing agent had been widespread concern because it has many advantages.However, the combustion temperature of aerosol fire extinguishing agent restricts its development.Lower combustion temperature of aerosol fire extinguishing agent not only can increase the payload of aerosol fire extinguishing agent, but also has effectively improve their fire performance.First, this paper adopted minimum free energy and mass conservation to theoretical calculate the combustion temperature of aerosol fire extinguishing agent which consisted of different types and levels of oxidants, combustible agent and a binder consisting.Then through horizontal and vertical contrast,oxidizer, flammable and adhesives impact of the combustion temperature of aerosol fire extinguishing agent was analyzed.The results showed that within a certain range, the combustion temperature of aerosol fire extinguishing agent with increasing oxidant content increasing,with the increase of the content of combustible With the increase of the content of combustible and reducing agent reducing.Increased binder content would lead to lower combustion temperature of aerosol fire extinguishing agent.
