Evaluation of Suppression of Hydroprocessed Renewable Jet (HRJ) Fuel Fires with Aqueous Film Forming Foam (AFFF)

摘要

Bio-oil derived hydroprocessed renewable jet (HRJ) fuels are alternative fuels that are being evaluated for use in United States Air Force (USAF) aircraft and support equipment and vehicles (SE&V). As with any new weapons system or other type of potential fire threat, the fire protection safety risk to the first responder must be established. This program was designed to determine if Military Specification MIL-F-24385F (MIL-SPEC) Aqueous Film Forming Foam (AFFF) has the capability of extinguishing HRJ fuel fires and HRJ/JP-8 blended fuel fires. The assessment included extinguishment effectiveness, extinguishment time, and burn-back time. Heat flux was also measured for six-foot pan fires with HRJ and synthetic alternative fuels and fuel blends. Jet fuels evaluated in this program were conventional JP-8 fuel (specified by MIL-DTL-83133F), two HRJ fuels produced by UOP LLC, a Synthetic Paraffinic Kerosene (SPK) fuel produced by Syntroleum Corporation (S-8) and a synthetic fuel produced by Shell (FT-IPK).
