摘要：
The interrelated redox processes in the high-temperature lower region of a blast furnace with a hybrid blast are analyzed. Particular attention is paid to the gas composition, the thermal effects of the reactions, and the motion of solids, liquids, and gases in the hearth’s tuyere region. The rate of moisture formation from the injected natural gas and also its decomposition rate in the lower part of the furnace are studied. The composition of elementary oxygen in coke combustion is determined as a function of the degree of oxygen enrichment of the blast. © 2015, Allerton Press, Inc.
