Abstract

An integrated and sustainable process is presented for the co-generation of pig iron and electric energy in a blast furnace installation in which dried wood replaces charcoal as the fuel, as the reducing and as the carburizing agent. Furthermore, this application incorporates the process -until now independent- of transforming wood into coal, inside the blast furnace.
