History of the iron furnace using the physical-chemical blast furnace model

The physical–chemical blast furnace model first built by Michard and Rist has proven to be a very efficient tool predict drive the present furnaces. It mostly describes iron as counter current gas-solids dual heat oxygen exchanger. onset of coke gasification (orelse oxide direct reduction), leads two-zones exchange model. This theory is used look back at operation earlier smaller furnaces such early XIX th century charcoal or much older low shaft shows interest using physical-chemical models better understand past production tools.
