Investigating carbon type differentiation techniques for blast furnace dust

Coal char presence in blast furnace dust, indicates the inefficiency of combustion raceway. A retroactive approach has been applied by investigating carbon sources dust via type differentiation methodologies. The current state art for similar applications consists thermogravimetric analysis, however this technique does not allow samples to be analysed line with ever-changing conditions furnace. Here, TGA method trialled use improvements offered heating profile, allowing faster analysis. Moreover, alternative techniques have trialled, combination characterisation methods such as XRD, SEM/EDS, total and ICP-OES. ‘Winkler Method’ originally designed quantify charcoal soil sediment, successfully optimised showing good correlation original benchmark technique.
