摘要

In ship's engine room, many fire detectors are positioned for rapid detection of the onset of fire, and most of them are smoke detectors. The purpose of this study is to present a guidance for the arrangement of smoke detectors under the actual ventilating condition in engine room. As the 1st report, this paper shows the performance results of smoke detectors in some fire tests based on the combustion of marine fuel oils. In the tests, the effects of height of detectors above fire source and the speed of ventilation air were investigated. In addition, considering fire alarm tests on board, we proposed the method of fire test using smoke signals for automobiles which is equivalent to fire test using marine fuel oils.
