Abstract:

The study was concerned with emission spectra of flames and combustion gases at low pressure of premixed oxygen-hydrogen-ethylene with various solid fuels plastics, with applications to chemiluminescence, kinetics and reaction mechanism elucidation. Premixed O2-C2H4-PH3 flames were also studied. Attempts to combust plastic samples with oxidizers directly at low pressure without a stable gaseous fuel-oxidizer flame were unsuccessful. Spectral scans coupled with thermochemical analyses indicated several bimolecular reaction mechanisms forming excited species at low pressure with characteristic signatures CH N to CN H N O to NO2pi to NO CH CH to C2 H2 C HO2 to CO OH C2 ClO to CCl CO CCl OH to CO HCl. In addition, emission bands from C3, NH, OH, CH, PO and a continuum possibly due to PO2 were seen. Author
