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 NO((2)pi) 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)
