SUMMARY
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 JF9SD.
The jet fire test JF9SD 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 JF9SD was to investigate the deluge effect on this type of fire with a short pre-burn time.
The fuel release rate was 0.93 kg/s, with a release pressure of 12.5 bar, keeping the ventilation opening fixed at 3.45 x 2.81 m, as in tests JF9, JF9B and JF9C. The fire became under-ventilated soon after ignition, with an air-to-fuel equivalence ratio of 0.59±0.15 (based on calculation of 32 seconds during transient period).
This technical report includes description of the test rig, the experimental details and a set of curves from the measured parameters.
