Study of the CL-20 Flame StructureUsing Probing Molecular Beam Mass Spectrometry

摘要

The CL-20 flame structure at pressures of 0.1 and 0.5 MPa was studied using probing molecular beam mass spectrometry. At a pressure of 0.1 MPa,the gaseous products near the surface of the foamy carbonaceous carcass were found to contain eight species: NO,NO2,CO,CO2,N2,H2O,HCN,and HNCO. At a pressure of 0.5 MPa,NO2 was not found and the concentration profiles of the remaining seven species were measured versus the distance to the carbonaceous carcass. In the CL-20 flame at a pressure of 0.5 MPa,consumption of N2 and CO2 with the formation of NO and HNCO occurred in a zone of width approx=0.8 mm from the surface of the carbonaceous carcass. At a pressure of 0.5 MPa,'the composition of the gaseous combustion products of CL-20 at a distance of 3-4 mm differed from the composition at thermodynamic equilibrium.
