Abstract
A study on combustion efficiency concept was conducted for the under-ventilated fires in a fullscale ISO 9705 room. In particular, a comparison between global combustion efficiency (CE) measured outside the compartment and local CE measured at upper layer inside the compartment was focused. Heptane, toluene and iso-propanol were used to consider the wide ranges of heat of combustion and soot yield. As a result, the global CE was decreased linearly with increasing in global equivalence ratio (GER). On the other hand, the decreasing rate of local CE was increased gradually with increasing in GER. From these results, it was known that the information on local CE was very useful parameter to understand the fire phenomena inside the compartment. In addition, it was discussed that the local CE might be used as an important parameter in the process of scaling for the compartment fires.
