FIRE SUPPRESSION TESTS OF THE WATER-MIST SYSTEMS IN THE MOCK-UP OF A PASSENGER COACH

초록

The present paper describes the fire suppression tests of the water-mist systems to suppress fire in passenger coach. The size of the mock-up performed the tests is 22 m length, 3 m wide and 2.3 m high. Six water-mist nozzles are installed in the test room. Three types of fire sources are also considered: The first is three 0.548 m x 0.548 m heptane pool (3.7 liters) fires: The second is two 0.1 m thick, 0.4m high and 2.0 m wide non-fire retardant polyether foam sets on the chair: The third is 0.775 m x 0.775 m heptane pool fire obstructed with a 1.5 m x 1.5 m steel plate. 24 thermocouples on the ceiling of the test room and 3 trees with 5 thermocouples measure temperature in the tests. According to “Guidelines of evaluation of water-mist system in a passenger coach” submitted by KRRI, three types of nozzles are evaluated.
