| 摘 要： | 蒸汽灭火系统在酒类作业场所有着广阔的应用前景.通过全淹没和局部保护实验对蒸汽抑制熄灭酒精池火的有效性进行了研究.实验结果表明,全淹方式难以有效控火,但是布局合理的局部保护方式能够有效熄灭酒精池火.蒸汽灭火过程中稀释O2浓度的灭火机理起到的作用较小,蒸汽的火焰拉伸效果是其主导灭火机理.

| Abstract: | Steam fire suppression system shows an expansive application prospect in alcohol-making industry.This paper investigated steam fire suppression efficiency with total flooding and local protection experiments.The result indicated that with a total flooding protection mode,steam can hardly control fire.But with a logical distribution,steam system showed high efficiency in suppression alcohol pool fire.The fire suppression mechanism of O2 dilution works slightly while the kinetic effect as flame stretching wor... |
