2. Blast furnace - Wikipedia

   en.wikipedia.org/wiki/Blast_furnace

   Blast furnaces used in the ISP have a more intense operation than standard lead blast furnaces, with higher air blast rates per m 2 of hearth area and a higher coke consumption. [ 79 ] Zinc production with the ISP is more expensive than with electrolytic zinc plants, so several smelters operating this technology have closed in recent years. [ 80 ]

3. John Wilkinson (industrialist) - Wikipedia

   en.wikipedia.org/wiki/John_Wilkinson_(industrialist)

   John Wilkinson was born in Little Clifton, Bridgefoot, Cumberland (now part of Cumbria), the eldest son of Isaac Wilkinson and Mary Johnson. Isaac was then the potfounder at the blast furnace there, [3] one of the first to use coke instead of charcoal, which was pioneered by Abraham Darby.

4. Regenerative heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Regenerative_heat_exchanger

   Regenerative heating was one of the most important technologies developed during the Industrial Revolution when it was used in the hot blast process on blast furnaces. [2] It was later used in glass melting furnaces and steel making, to increase the efficiency of open hearth furnaces , and in high pressure boilers and chemical and other ...

5. List of preserved historic blast furnaces - Wikipedia

   en.wikipedia.org/wiki/List_of_preserved_historic...

   Two blast furnaces have been preserved, including outer frames, furnaces and Cowper stoves. A protective paint coating minimizes the rusting effects on the blast furnaces. Blast furnace 6 is accessible to the public as part of guided tours. A colorful light installation illuminates the entire area at nighttime. [9] [10] Sulzbach-Rosenberg, Bavaria

6. Pulverized coal injection method - Wikipedia

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

   The blast furnace method is expected to survive into the 22nd century because of its efficient rate of iron production at competitive costs compared with other iron-making methods. Blast furnaces keep on improving with adaptations arising from new technologies driven by rising global demand, yet the main chemical process remains the same. But ...

7. James Beaumont Neilson - Wikipedia

   en.wikipedia.org/wiki/James_Beaumont_Neilson

   Experimentation showed that a temperature of 600°F reduced fuel consumption to a third of that with cold blast, and enabled raw coal to be used instead of coke, with a further cost saving. It also enabled the exploitation of black band ironstone , the use of which had previously proved unprofitable.
