Abstract:

This work investigates the effects of applying a new Oxy-Fuel technique to the stoves of a blast-furnace. In this new concept, the flue gas is mixed with industrial oxygen and recirculated back to the hot stove burners, replacing combustion air with a hot synthetic oxidant. A model was used to analyse the possible changes of blast temperature, consumed process gases (e.g. blast furnace gas, coke oven gas), flue gas volume and composition when applying the new OxyFuel technique to the hot stove system. The model was combined with a blast furnace (BF) model to simulate the changes on BF's operation and finally the implications for the entire steel production system of a European standard integrated steel plant were predicted. The potential energy saving and CO2 emission reduction are presented, and the influences on the production cost are discussed as well.
