Abstract
Burning rates, temperatures, and gaseous products were determined for experimental fires of ethyl-alcohol (64175) and paraffin oil (8012951) in a 0.2 cubic meter partially ventilated enclosure. Both laminar and turbulent modes, as predicted by Spalding's equations, were observed and corresponded to nonboiling and boiling periods respectively, at a constant pan diameter. Four regions, similar to those found for wood fires, were identified. An equation was included which can be used to identify a critical condition which may occur in residential home fires, corresponding to extreme danger. Extension and contraction of the reaction zone were defined on the basis of temperature and product distribution inside the enclosure. Vertical temperature distribution was used to map the shifting of the approximate boundary between hot products and air. The author concludes that the results of the study should be useful to architects in designing ventilation for rooms to minimize hazard to life from lethal atmospheres during fires in homes.
