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 JF8.
Jet fire test JF8 represents a vertical release of condensate (a liquid fraction from an oil refinery) at low level in a 415 m3 enclosure with a 3.45 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 JF8 was to investigate the variations in air/fuel ratio on fire behaviour by changing the fuel flow rate during the test.
The fuel release rate was varied in five steps, between 0.86 kg/s and 1.04 kg/s, by variation of release pressure from 9.6 bar to 14.0 bar, keeping the ventilation opening fixed at 3.45 x 2.81m. The fire became under ventilated soon after ignition, with a variation of equivalence ratio of 0.62±0.16 to 0.52±0.14.
This technical report includes description of the test rig, the experimental details and a set of curves from the measured parameters.
