Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <p>Steel slag, desulphurisation slag of molten iron during steelmaking and red iron oxide in cold rolling were used as coal burning additives. The objective of this study was to investigate ignition temperature and burnout characteristics of coal by thermal gravimetric analysis. The results indicated that coals and wastes type had significant influences on the catalytic combustion. The ignition temperature and burnout time of catalytic samples were all decreased; meanwhile, the burnout index of catalytic samples were enhanced. Red iron oxide in cold rolling was the optimal coal burning additive. The study exploits a new way to use the wastes of steel industry and provides some important theoretical data and a useful basis for further applying coal with high efficiency.</p> </abstract>
