A large amount of NOx will be produced during the combustion process of waste energetic materials (EMs), which is extremely harmful to human health and ecological environment, and has become an urgent problem for all countries to solve. In this paper, the NOx emission characteristics of four typical types of waste EMs (double-base propellant, TNT, triple-base propellant and RDX) under different temperature and atmosphere conditions were studied by tube furnace experiment. The results showed that under the condition of nitrogen environment, with the increase of temperature, the combustion reaction of waste EMs was accelerated, NOx emission and nitrogen conversion rate decreased. Under the same experimental conditions, the nitrogen content of waste EMs was not proportional to nitrogen conversion. With the increase of oxygen content, NOx emissions and nitrogen conversion rate increased, which was not conducive to the control of NOx emissions. Therefore, the waste EMs burned in 1000 ℃ and nitrogen environment, the emission of NOx was the lowest. The results of this study provide reliable data support for the realization of green and clean burning of waste EMs.
