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 JF12.
Jet fire test JF12 represents a vertical release of condensate (a liquid fraction from an oil refinery) at low level in a 415 m3 enclosure with a 5.5 x 2.81 m opening at one end. The general fire behaviour such as flame geometry and characteristics, temperature field and heat load from naturally ventilated fires was studied. The main purpose of test JF12 was to investigate the air/fuel ratio on fire behaviour by increasing the ventilation rate related to tests JF4, JF5 and JF8.
The fuel release rate was 0.95 kg/s with a release pressure of 12.3 bar, the ventilation opening is increased related to tests JF4, JF5 and JF8. The fire became under ventilated soon after ignition, with a variation of equivalence ratio of 0.82±0.21.
This technical report includes description of the test rig, the experimental details and a set of curves from the measured parameters.
