Assessment of hazardous air pollutants from disposal of munitions in a prototype fluidized bed incinerator.

As part of the control technology development for the disposal of waste munitions, an assessment of potential emissions of hazardous air pollutants from a prototype fluidized bed incinerator was conducted. Assessment program elements included identification of potentially toxic emissions through material input analysis and computer simulation modeling of the combustion cycle; development of emission limitations criteria for substances having no present air pollution emission standards; evaluation and development of analytical procedures; and design of a sampling system to condition an emission stream characterized by high temperature and humidity resulting from burning water slurries of explosive materials. Emphasis is placed on the potential emission of nickel and its compounds, particulate and vapor emissions of cyanides, nitrogen oxides, and TNT and RDX energetic residuals.
