T1 - Thermal radiation impact of DTBP fireballs T2 - NTREM ’16 - Proceedings of Seminar on New Trends in Research of Energetic Materials N2 - The burning behaviour and thermal radiation of pool fires of organic peroxides (OP) have been studied by several authors in the past. It was shown that mass burning rates, flame temperatures and thus the Surface Emissive Power (SEP) of OP exceed to that of hydrocarbons considerably. These facts lead to further investigations of even dangerous worst case scenarios i.e. related to storage and transportation. A metal drum containing 200 l of DTBP (Di-tert-butyl peroxide) is investigated under a surrounding wood fire. Due to a higher heat flux to the substance, the mass burning rate reaches multiples of an equivalent pool fire and results in several fireballs. The analyses of thermographic camera images and radiometer measurements show higher flame lengths, higher temperatures and thereforeincreased thermal radiation compared to OP pool fires. The resulting greater safety distances for a DTBP fireball event are discussed.
