摘要：
Abstract: This article discusses the improvement methods of blast furnace energy efficiency by combined injection of preheated pulverized coal fuel and iron oxides (concentrates of advanced beneficiation, flue dust, and others) into its tuyeres. The reasonability of the aforementioned measures is substantiated. Based on the overall energy balance, their influence on heat energy parameters of blast furnace smelting has been established including its exergy, environmental, and technoeconomic performances. It has been determined that injection of preheated pulverized coal fuel into blast furnace well together with constant temperature of the tuyere area allows to increase the furnace output by at least 0.3% per each 100°C increase in the temperature of pulverized coal fuel, to decrease coke consumption by about 3%, and to increase exergy efficiency by up to 0.2%. Favorable influence of injection of pulverized iron oxides into blast furnace well of blast furnace on heat and gas dynamic operation of the furnace are demonstrated. © 2021, Allerton Press, Inc.
