  2. Hot blast - Wikipedia

    en.wikipedia.org/wiki/Hot_blast

    Hot blast allowed the use of anthracite in iron smelting. It also allowed use of lower quality coal because less fuel meant proportionately less sulfur and ash. [11]At the time the process was invented, good coking coal was only available in sufficient quantities in Great Britain and western Germany, [12] so iron furnaces in the US were using charcoal.

  3. Anthracite - Wikipedia

    en.wikipedia.org/wiki/Anthracite

    The moisture content of fresh-mined anthracite generally is less than 15 percent. The heat content of anthracite ranges from 26 to 33 MJ/kg (22 to 28 million Btu/short ton) on a moist, mineral-matter-free basis. The heat content of anthracite coal consumed in the United States averages 29 MJ/kg (25 million Btu/ton), on the as-received basis ...

  4. Blast furnace - Wikipedia

    en.wikipedia.org/wiki/Blast_furnace

    Within a few decades, the practice was to have a "stove" as large as the furnace next to it into which the waste gas (containing CO) from the furnace was directed and burnt. The resultant heat was used to preheat the air blown into the furnace. [69] Hot blast enabled the use of raw anthracite coal, which was difficult to light, in the blast ...

    en.wikipedia.org/wiki/AGA_cooker

    Forced to stay at home, Dalén discovered that his wife was exhausted by cooking. Although blind, he set out to develop a new stove that was capable of a range of culinary techniques and easy to use. Adopting the principle of heat storage, he combined a heat source, two large hotplates and two ovens into one unit: the Aga Range Cooker.

  6. Anthracite iron - Wikipedia

    en.wikipedia.org/wiki/Anthracite_iron

    Anthracite iron or anthracite pig iron is iron extracted by the smelting together of anthracite coal and iron ore, that is using anthracite coal instead of charcoal in iron smelting. This was an important technical advance in the late-1830s, enabling a great acceleration of the Industrial Revolution in the United States and in Europe. [1]

  7. Coal breaker - Wikipedia

    en.wikipedia.org/wiki/Coal_breaker

    Anthracite coal began to be widely used in Wales in 1813 and France by 1814, and throughout the eastern United States by 1828. [11] [13] Efforts were soon made to discover ways to process anthracite coal to achieve the desired uniformity. The modern coal breaker can be traced to 1844. [4]
