Design of a Water Deluge to Extinguish M-1 Propellant Fires in Closed Conveyors.

摘要

A water deluge system was designed to protect a vibrating conveyor line at Radford AAP which transports in-process propellant in various parts of the new Continuous Automated Single Base Line (CASBL). Full scale tests on a simulated conveyor line proved that a water deluge system can be effectively used to control propellant fires and to prevent the hazardous rise of pressure within the enclosed conveyor. An ultraviolet detector proved to be the most responsive type of fire sensor. The use of this system will eliminate the costly fire gates which had been proposed. Since the pressure rise in the closed conveyor can be limited to less than 55000 pa (approximately 8 psi), the proposed pressure vents can be eliminated. By using the more responsive UV detectors, the redundant IR detectors can also be abandoned. (Author)
