Abstract

An expression for oil replacement ratio has been fully derived on the basis of theoretical carbon rate with or without oil injection.
As two examples of the modified blast, injection of a large amount of heavy oil combined with exygen enriched blast or with high temperature blast have been discussed by the proposed method.
Moreover, the operating results of domestic blast furnaces with liquid fuel injection have been analyzed statistically.
