摘要

对室内送排风系统的不同运行模式进行了火灾探测实验。确定了送排风系统的运行条件,以排除 A 类材料(木材、纸板和油毡)热分解、气化和燃烧产物形成的危险浓度。在送排风系统的不同运行模式下,以及在不同的热分解和火焰燃烧启动机制下,记录了气体-空气混合物成分(CO、O2、CO2)浓度的变化。确定了供气和排气通风系统的性能特点,这些特点对于火灾探测、遏制和灭火系统的有效运行是必要和充分的。

Impact of supply and exhaust ventilation system on gas concentrations in a compartment during thermal decomposition and combustion of materials

Experiments were conducted on the detection of fires when using different operation modes of an indoor supply and exhaust ventilation system. The operating conditions of the supply and exhaust ventilation system were identified that exclude the formation of hazardous concentrations of products of thermal decomposition, gasification and combustion of class A materials (wood, cardboard and linoleum). The changes in the concentrations of the gas-air mixture components (CO, O2, CO2) were recorded in different operation modes of the supply and exhaust ventilation system and for different mechanisms of thermal decomposition and flame combustion initiation. The performance characteristics of the supply and exhaust ventilation system were determined that are necessary and sufficient for efficient operation of fire detection, containment and suppression systems.

期刊介绍: Fire Safety Journal is the leading publication dealing with all aspects of fire safety engineering. Its scope is purposefully wide, as it is deemed important to encourage papers from all sources within this multidisciplinary subject, thus providing a forum for its further development as a distinct engineering discipline. This is an essential step towards gaining a status equal to that enjoyed by the other engineering disciplines.
