  2. Blast furnace - Wikipedia

    en.wikipedia.org/wiki/Blast_furnace

    Variations of the blast furnace, such as the Swedish electric blast furnace, have been developed in countries which have no native coal resources. According to Global Energy Monitor , the blast furnace is likely to become obsolete to meet climate change objectives of reducing carbon dioxide emission, [ 72 ] but BHP disagrees. [ 73 ]

  3. Zinc smelting - Wikipedia

    en.wikipedia.org/wiki/Zinc_smelting

    The process starts by charging solid sinter and heated coke into the top of the blast furnace. Preheated air at 190 to 1,050 °C (370 to 1,920 °F) is blown into the bottom of the furnace. Zinc vapour and sulfides leave through the top and enter the condenser. Slag and lead collect at the bottom of the furnace and are tapped off regularly.

    Blast Furnace in Govăjdia built between 1806 and 1810 on the site of an old iron working workshop called "Old Limpert", the furnace's capacity is 43,9 cubic meters and it operated with charcoal brought from Vadu Dobrii and the iron ore mined and brought from the iron ore mines at Ghelari via narrow-gauge railway. It was decommissioned in 1924 ...

  6. Regenerative heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Regenerative_heat_exchanger

    For example, a blast furnace may have several "stoves" or "checkers" full of refractory fire brick. The hot gas from the furnace is ducted through the brickwork for some interval, say one hour, until the brick reaches a high temperature. Valves then operate and switch the cold intake air through the brick, recovering the heat for use in the ...

  7. Pulverized coal injection method - Wikipedia

    en.wikipedia.org/wiki/Pulverized_coal_injection...

    The PCI method is based on the simple concept of primary air (termed the "conveying gas") carrying pulverized coal which injected through a lance to the tuyere (mid-bottom inlet of a blast furnace), then mixed with secondary hot air (termed the "blast") supplied through a blowpipe in the tuyere and then piped to a furnace to create a balloon ...

    en.wikipedia.org/wiki/Charcoal_iron

    The last working furnace at Backbarrow converted to coke in 1922. In Western Australia, pig iron was made using charcoal between 1948 and 1981 at Wundowie. [4] At its peak, operating two charcoal-fueled blast furnaces, the Wundowie charcoal iron and wood distillation plant produced 52,262 tons of iron in 1960/61. [4]

  9. Corex Process - Wikipedia

    en.wikipedia.org/wiki/Corex_Process

    The Corex Process is a smelting reduction process created by Primetals Technologies as a more environmentally friendly alternative to the blast furnace. [1] Presently, the majority of steel production is through the blast furnace which has to rely on coking coal [2] and requires a sinter plant in order to prepare the iron ore for reduction. [3]
