- Abstract
- The present work investigated the evolution of exhaust gases from an underventilated liquid hexane pool fire inside a reduced-scale compartment with and without Douglas fir plywood hung 0.05 m below the ceiling. The work focused on the production of carbon monoxide (CO) and unburned hydrocarbons (UHC) inside the compartment and the transport and oxidation of the fire exhaust gases in a hallway adjacent to the burning compartment. The presence of the wood in the upper layer was seen to increase CO concentrations inside the compartment by as much as 3.1%-dry to 13.6%-dry (over 4 times higher) while the UHC concentrations increase were seen to increase from 2.3%-dry to 7.3%-dry (approximately 3 times higher). The exhaust gases exited the hallway containing 2.9%-dry CO with a wood ceiling in the compartment compared with 0.5%-dry CO when no wood ceiling was in the compartment. The UHC were always oxidized more effectively than the CO by the end of the hallway.
