Hinshaw, G., G. Huffman, AND P. Lin. FORMATION AND CHARACTERIZATION OF SOOT DEPOSITS FROM NON-OPTIMUM COMBUSTION OF NO. 6 FUEL OIL WITH CHLORINATED ORGANIC COMPOUNDS IN AN INDUSTRIAL BOILER. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/J-93/434 (NTIS PB94101904), 1992.
Description:
During a full-scale hazardous waste combustion study performed for EPA, sampling and analysis was conducted on both stack gases and solid "soot" collected from a boiler's interior surfaces. wo organochlorine compounds, monochlorobenzene (MCB) and trichloroethylene (TCE), were cofired with fuel oil, followed by a natural gas fuel firing phase using only natural gas. he sorption and later desorption of uncombusted organic compounds on soot, (termed hysteresis) was the focus of the study. oot samples and stack gases were analyzed for volatile and semivolatile organic compounds. echnique involving thermal desorption-GC/MS (gas chromatography/mass spectrometry) was developed and used for the combustion study soot analysis. n addition, selected samples were analyzed by electron beam techniques, i.e., scanning electron microscopy (SEM) combined with energy dispersive x-ray spectroscopy (EDX), and by laser induced plasma spectroscopy (LIPS) to determine morphology, size, and elemental composition of soot particles. hlorine composition was studied as an indirect measure of chlorinated organic compounds.
