Abstract [en]

Pulverized coal is often injected into the blast furnaces (BFs) at the integrated steelworks as reducing agent for the hot metal production. The BF process will behave different depending on the injection coal used. The objective of this study is to investigate how different types of coal will influence the BF, and the total energy system atan integrated steel plant. The major process units covered in the model are coking plant, BF, reheating furnace at the rolling mill and a power plant. They are all linked to each other via the main products as well as process gases (i.e. blast furnace gas (BFG)and coke oven gas (COG)) and oxygen network. At the studied plant, the mixed gas of BFGand COG is used within the coking batteries at the coking plant and hot stoves at the BF. The fuel used at the reheating furnace is COG and oil with high heating values. In total, 13 different types of coal and one biomass charcoal are included in the study. Possible impacts on energy and CO 2 emission from a holistic view have been analyzed for different types of coal and injection rates. The different strategies on pulverized coal injection to BF are presented and discussed.
