Combustion of pulverized coal with additives under conditions simulating blast furnace injectionCombustion of pulverized coal with additives under conditions simulating blast furnace injection Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-261996enThe combustion properties of pulverized coal with additives were studied under conditions simulating injection into the blast furnace (heating rate 105 K s−1, residence time <20 ms, final temperature 1500°C). Coal rank, particle size and injection rate were varied. The additives were residuals from scrap automobiles (shredded light fractions), in various proportions. The performance of the coals tested was very dependent on coal rank and injection rate. The degree of combustion was generally improved with larger particle sizes at oxygen/coal ratios greater than the stoichiometric value. An increase in the amount of additive resulted in a lower degree of burnout. By using shredded light fractions in proportions up to 30 wt% with Lohberg coal and up to 10 wt% with N.Pedio lignite, a high level of burnout and a high injection rate could be achieved.http://creativecommons.org/licenses/by/4.0/Fuel7591145-1150 Vamvouka Despoina Βαμβουκα Δεσποινα Schwanekamp, Guido Gudenau, Heinrich Wilhelm Elsevier Pulverized coal Automobile scrap Combustion properties
