Gaseous Emissions from Excess Air Combustion of Explosives and Propellants

摘要

The purpose of this short-term project was to determine the levels of nitric oxide (NO), nitrogen dioxide (NO2), and carbon monoxide (CO) in the off-gases from the open burning of explosives in excess air. The ultimate goal is to reduce the level of NO(x), CO, and particulates emitted during the destruction of surplus, waste, and off-spec, explosives. Previous work (DOE) showed that a gravel/sand filter in the roof of a bunker reduced the level of particulates emitted during excess air combustion of propellants (only limited No(x) or CO measurements were reported). The project demonstrated that the filter is effective in partially eliminating NO and CO emissions, but that additional work, including the incorporation of catalysts in the bed and the introduction of NO-control gases (e.g., NH3), should be undertaken.
