Development of a Water Deluge System to Extinguish M-1 Propellant Fires.
Abstract
In support of the U.S. Army Modernization Program, and the modernized 105-mm, M-67, bag loading and assembly operations, an effective water deluge system was designed and tested to extinguish a fire should it occur in either the bulk M-1 receiving hoppers, or the bagged M-1 accumulator conveyors. The feasibility of using a water deluge was first demonstrated, then a deluge system was designed which carefully considered the in-plant conditions when selecting an appropriate fast-response detector, a rapid-acting water valve, and the water pressure and water availability at the Indiana AAP. To evaluate the ability of a water deluge to extinguish M-1 propellant fires, full scale tests were conducted under the most stringent in-plant conditions. Plant construction and layout were simulated to evaluate effects of rising temperatures and pressures prior to fire extinguishment. Time response of the detectors and time to water application were monitored and recorded. Detailed designs of the unique deluge systems for both hopper and accumulator applications are given and are demonstrated to meet the two predominent requirements: (1) ability to extinguish the fire without severe building damage and fire propagation, and (2) a deluge system operating within the limits of water pressure and water volume available.
