Test Programme F3 - Confined Jet and Pool Fires - Technical Report for Test JF5
BFETS Phase 2
SINTEF Energy - Norwegian Fire Research Laboratory 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 JF5.
The jet fire test JF5 was carried out to study the characteristics like the temperature field and heat load from a naturally ventilated fire using a fuel fraction from an oil refinery (Condensate). Similar tests with condensate (JF8) and gaseous propane (JF4) as fuel have been carried out in the test programme, as well as a similar test in smaller scale (135 m3 enclosure). Differences in fire behaviour and characteristics with fuel type and scale may be studied from these tests.
The general fire behaviour depending on enclosure geometry, ventilation arrangement and fuel release parameters is also studied in the test programme. This test represents a fire with a vertical jet release at low level. The flow of fuel was varied, at 0.85 kg/s and 0.75 kg/s, with a release pressure of 16.5 bar and 12.7 bar respectively. The fire was under-ventilated, with a variation of air-to-fuel equivalence ratio of 0.60±0.16 at level 1 and 0.70±0.18 at level 2.
This technical report includes description of the test rig, the experimental details and a complete set of curves from the measured parameters.
