摘要/Abstract

摘要： 乙醇沸点低、易挥发的特点使其在燃烧时易沸腾、状态易突变，会对抗醇泡沫灭火剂的灭火性能造成极大的影响。本文设计并构建温控操作平台和燃烧试验平台，对抗醇泡沫灭火剂的铺展特性进行试验，从灭火机理出发探究温度上升导致的沸腾状态变化对抗醇泡沫灭火剂铺展窒息效果的影响，进而探究乙醇沸腾状态对抗醇泡沫灭火剂灭火性能的影响规律，为消防救援队伍处置乙醇火灾提供相关数据和理论支持。

Abstract: The low boiling point and volatile characteristics of ethanol make it easy to boil and mutate when burning, which will greatly affect the extinguishing performance of alcohol foam extinguishing agent. This paper designs and constructs a temperature control operation platform and a combustion test platform to test the spreading characteristics of alcohol resistant foam extinguishing agent. From the fire extinguishing mechanism, this paper explores the influence of the boiling state change caused by temperature rise on the spreading asphyxiation effect of alcohol resistant foam extinguishing agent, and then explores the influence of ethanol boiling state on the extinguishing performance of alcohol resistant foam extinguishing agent, providing relevant data and theoretical support for the fire rescue team to deal with alcohol fires.

Key words: ethanol fire, boiling, alcohol-resistant foam, spreading behaviors
