The CANMET Energy Technology Centre (CETC), in cooperation with the Department of Energy of the Province of Alberta and the Canadian Carbonization Research Association (CCRA), has completed a program on the evaluation of Canadian and foreign coals for blast furnace injection. The program consisted of two parts: (1) theoretical assessment of cooling and coke replacement characteristics of coals using CETC`s computer model and (2) experimental determination of the combustibility of coals of different ranks and particle size as well as the influence of oxygen enrichment on burnout. The experimental part was conducted in a pilot-scale injection unit designed and built at CANMET that simulates blast furnace blowpipe-tuyere conditions. This paper describes the facility and methodology of work. It also discusses results. The prime objectives of this study were to provide essential information on coal combustion in the blast furnace and establish proper criteria for evaluating and selecting coals for blast furnace injection.
