| Popis: | Many oil fires have resulted from the crude oil train derailments in recent years. Given the importance of crude oil shipping by rail to the energy security of the US, it is important to consider various methods that will decrease the likelihood of crude oil catching fire in case of a crude oil derailment. Present study examines the effect of polybutadiene polymer on the combustion properties and soot deposits of Bakken and Pennsylvania crudes. Treating these crudes as multicomponent liquid fuels and polybutadiene as an additive, droplet combustion experiments were conducted with sub-millimeter sized spherical droplets suspended on very fine support fibers. Polybutadiene polymer additive of two different chain lengths has been investigated. Results show that both polymer chain length and origin of crude oil have a significant effect on various combustion properties like combustion rate, ignition delay, total combustion time, and flame stand-off ratio. Polymeric additives also change the soot deposit structure and particle size compared to the base fuel. Present research is envisioned to aid in theoretical combustion modeling of complex multicomponent liquid fuels, as well as generate interest in investigating more polymeric additives for liquid fuels. 37 pages, 25 figures, article under review in Elsevier Appl Energy |
