THE IRON BLAST FURNACE AND DRI SHAFT FURNACE - A COMPARISON OF SOME PROCESS DEVELOPMENTS

摘要

An analysis of the blast furnace and the low-pressure shaft DR furnace is carried out by redefining the reaction zones. The concept of a characteristic reaction gas temperature (CRGT) is introduced and the two reactors are compared and contrasted using some recent process developments with an aim to develop a platform for further synergistic innovations.
