Computational modeling of a chemical demilitarization Deactivation Furnace System

Issues considered during the development of models for evaluating the Deactivation Furnace System (DFS) are reviewed. The DFS was created for the processing of rockets containing the agent GB (i.e., Sarin). The DFS was established by the US Army as an incineration system capable of destroying the highly toxic chemical agents and munitions contained in the US chemical weapons stockpile. The DFS system was developed as a gas-fired counterflow rotary kiln for the treatment of several different energetics, including fuses, boosters, bursters, and solid rocket propellant. The two main parts of the DFS model are an energetics/rocket combustion submodel integrated with a transient zone furnace combustion model, and a gas-phase combustion/destruction computational fluid dynamics model.
