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 JF4.

Jet fire test JF4 is representing a vertical release of pressurized gaseous propane at low level in a 415 m3 enclosure. The general fire behaviour depending on enclosure geometry, ventilation arrangement and fuel release parameters is also studied in the test programme.

The main purpose of jet fire test JF4 was to have a reference experiment with gaseous propane as fuel in a series of tests with liquid condensate. Additionally, similar test has been carried out in the smaller scale (135 m3 enclosure) in an earlier test series.

The flow of fuel was varied, at 0.84 kg/s and 1.08 kg/s, with a release pressure at nozzle of 3.3 bar and 4.6 bar respectively, keeping the ventilation opening fixed at 3.45 x 2.81 m. The fire became under-ventilated soon after ignition, with a variation of equivalence ratio of 0.63±0.16 at level 1 and 0.51±0.13 at level 2.

This technical report includes description of the test rig, the experimental details and a set of curves from the measured parameters.
