Investigation of Methods for Detection and Control of Pyrotechnic Dust Fires and Explosions

Abstract

The characteristics of sulfur dust fires and a method for control based on UV detection and high-pressure suppression were investigated. Sulfur/ air dispersions were found to be subject to low-order detonations, accompanied by relatively slow-moving flame fronts. A high-pressure quench system, with a burst diaphragm triggered from a ultraviolet sensor, was found to control these reactions satisfactorily. Water was found to be less efficient as a suppressant than halogenated hydrocarbons.
