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 pool fire test PF14.

The pool fire test PF14 represents a 24 m² pool fire of condensate (a liquid fraction from an oil refinery) on a water bed in 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 test PF14 was to investigate the variation in fire behaviour by changing the ventilation opening into a split area, but keeping the same total ventilation area as in test PF11.

The fuel burning rate was ~1.5 kg/s. The ventilation opening was 5.5 x 1.56 m in the upper part of the east end wall and 5.5 x 1.37 m in the lower part of the east end wall, with a 5.5 x 3.0 m wall element in between. The fire became well ventilated soon after ignition, with an equivalence ratio of 1.27±0.61.

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