Abstract

This paper describes the development of a transient multi-dimensional mathematical model of the blast furnace and its application to simulate several innovative operations. The model simulation on hydrogen bearer injection shows that the enhancement of hydrogen reduction brings an improvement in furnace performance, especially for injection of natural gas and plastics. Another simulation shows that carbon composite agglomerate charging decreases the thermal reserve zone temperature. However, blast furnace efficiency is improved. The third application is to investigate blast furnace performance under top gas recycling together with plastics injection, cold oxygen blasting and carbon composite agglomerates charging. The model predicted lower in-furnace temperature, extremely accelerated reduction speed, drastically decreased C emission and remarkably enhanced heat efficiency. Thus, blast furnace operation with super high efficiency can be achieved through the practical applications of these innovative technologies.
