Additionally, 网页One of the most expensive and pollution-prone aspects of blast furnace operation is the production of coke. To reduce coke usage, blast furnaces may inject natural gas or pulverized coal directly into the blast furnace. SO x removal is achieved via installation of sintering flue gas desulfurization equipment. 网页2020年6月2日The decreasing supply and increasing price of prime coking coals forces coke manufacturers to look for new solutions to enhance the quality and economics of the coke-making process [1,2,3,4].Coke is an essential raw material in the iron- and steel-making sectors [], where in the blast furnace process it plays the role of a fuel, a 网页DOI: 10.1016/J.PROENG.2015.01.294 Corpus ID: 110020018; Modeling Coal/coke Combustion Behavior in Tuyere-raceway-dripping Zone in Blast Furnace @article{Tang2015ModelingCC, title={Modeling Coal/coke Combustion Behavior in Tuyere-raceway-dripping Zone in Blast Furnace}, author={Huiqing Tang and Fanqing Meng and 网页@article{osti_7021514, title = {Use of coal injection and oxygen in a blast furnace to produce fuel gas.
