    Bessemer converter, schematic diagram. The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also ...

    Schematic diagram of an industrial process furnace. Fuel flows into the burner and is burnt with air provided from an air blower. There can be more than one burner in a particular furnace which can be arranged in cells which heat a particular set of tubes. Burners can also be floor mounted, wall mounted or roof mounted depending on design.

    [note 2] The reduction of metal oxides with carbon (or carbon monoxide) to form the free metals is of immense industrial importance (e.g., the manufacture of iron in a blast furnace), and Ellingham diagrams show the lowest temperature at which the reaction will occur for each metal. [2] He married Doris Karin Russell in Kensington in 1945.

  9. Direct reduction (blast furnace) - Wikipedia

    en.wikipedia.org/wiki/Direct_reduction_(blast...

    For blast furnaces, direct reduction corresponds to the reduction of oxides by the carbon in the coke. However, in practice, direct reduction only plays a significant role in the final stage of iron reduction in a blast furnace, by helping to reduce wustite (FeO) to iron. In this case, the chemical reaction can be trivially described as follows ...
