Test Programme F3 - Confined Jet and Pool Fires - Technical Report for Test JF9B
BFETS Phase 2
SINTEF Energy - Norwegian Fire Research Laboratory (NBL) has the task to carry out a series of fire tests with confined jet and pool fires, according to the test programme F3 of Blast and Fire Engineering for Topside Structures. This report is for jet fire test JF9B.
The jet fire test JF9B represents a horizontal release of condensate (a liquid fraction from an oil refinery) pointing inwards from the ventilation opening, into a 415 m3 enclosure.
The general fire behaviour such as flame geometry and characteristics, temperature field and heat load from this naturally ventilated fire was studied. The main purpose of jet fire test JF9B was to find the influence of jet orientation on fire behaviour and to repeat test JF9, which produced a severe fire and caused extensive damages to the enclosure.
The fuel release rate was 0.95 kg/s, with a release pressure of 12.6 bar, keeping the ventilation opening as in tests JF5 and JF8. The fire was under ventilated, with an air-to-fuel equivalence ratio of 0.52±0.14.
This technical report includes a description of the test rig, the experimental details and a set of curves from the measured parameters.
