Burning Rate and Carbon Monoxide Production for an elevated pool fire in a weakly ventilated compartment

Résumé

This work concerns the study of fires in ventilated compartments, and in particular scenarios involving fire located in the upper part of a room near ceilings and in under-ventilated conditions. These complex scenarios are poorly understood and require better knowledge for fire risk assessment. A reduced-scale experimental study with dodecane pool fires was carried out to investigate the coupled influence of fire elevation and compartment ventilation flowrate. The fire characteristics of interest are burning rate and CO production. The results show that fire elevation and ventilation flow rate have opposite influence on burning rate. The net balance is a positive effect of elevation, increasing the burning rate even in an oxygen-poor environment. On the contrary, elevation and ventilation flowrate have a same positive influence on CO production and contribute to its increase. This work shows the complexity of a fire in the upper part of a poorly ventilated room and provides new knowledge to improve its prediction for safety assessments.
