This paper mainly emphasizes development of a multifluid blast furnace model and its application to simulate several innovative ironmaking operations. At first, the development process and framework of the model are briefly introduced. Then, model simulations on hydrogen bearer injection show that the enhancement of hydrogen reduction brings the improvement(More)
A blast furnace process is modeled as a continuously operating reactor, where a stream of solid particles (coke and iron ore) and a stream of blast gas interact through heat transfer, fluid flow and chemical reactions. The furnace can be classified as a counter-current moving bed reactor where the bed of the solid particles of iron ore and coke moves(More)
