Využití vodíku ve vysoké peci jako náhrada vysokopecního koksu

Abstract

The combustion of coke produces a large amount of thermal energy which is required for the production of pig iron, but at the same time the oxidation of the carbon present in the coke also produces a large amount of CO2. This flue gas formation cannot be completely avoided, but can be reduced by replacing coke with a non-carbon alternative fuel such as hydrogen, which is the focus of this paper. It is quite significant that hydrogen cannot replace all the coke where coke is also needed as a reducing agent, carboniser and provides the structural framework for the blast furnace areas. Thus, this work is devoted to the analysis of the world knowledge in addition to the determination of the maximum possible replacement of the fuel by gas, and this is then transferred to the calculation of the reduction of CO2.
