Abstract

A series of fire experiments has been conducted to provide an improved understanding of the fire structure of under-ventilated compartment fires. A comprehensive and quantitative assessment of gaseous species from the fire was made in the upper layer of fire in a 40 % reduced scale ISO 9705 fire compartment. The global equivalence ratio (GER) concept was used to characterize the fire behavior for various fire sizes, fuel types and ventilation conditions. The oxygen concentration in the upper layer reached to zero near the global equivalence ratio of $0.4{\sim}0.6$ while the carbon monoxide concentration increases with increasing the global equivalence ratio. Classification parameters of ISO19706 were also compared with the reduced scale experimental data for under ventilation fire.
