Environmental Protection Progress of Combustion Gas Formed by Nitrogen-Rich Compound Pyrotechnics

In this paper, the main harmful gases produced from the burning of nitrogen-rich compound gas generating agent were introduced, the progress of qualitative and quantitative detection research on typical pyrotechnics combustion gas over the world was reviewed, and various detoxification methods for the combustion gas from nitrogen-rich compound gas generating agent were described. At last, further environmental emissions of burning gases with the nitrogen-rich compound pyrotechnics were discussed and expected.
