Originally a charcoal furnace, the old blast furnace at Coalbrookdale was leased in 1709 by Abraham Darby I, who used it to make coke pig iron and created the first long-term business to do so. The furnace remained in use until the 19th century and now forms part of the Ironbridge Gorge Museum Trust's Museum of Iron. IGMT: Madeley Wood or Bedlam
Cyclone Furnaces can handle a wide range of fuels. Low volatile bituminous coals, lignite coal, mineral rich anthracitic coal, wood chips, petroleum coke, and old tires can and have all been used in cyclones. The crushed coal is fed into the cyclone burner and fired with high rates of heat release.
Furnaces, like blast furnaces, are lined internally with refractory layers of chamotte or silicate. Each furnace has three openings: the front and rear doors, which are about as wide as the furnace itself, and the filling/emptying hatch at the top. An oleo-hydraulic rake adjusts the coal layers horizontally inside the furnace. [10] [11]

In 1713, a process was invented for producing coke suitable for blast furnaces from hard coal (stone coal). From then on, the consumption of the more expensive charcoal decreased steadily despite increasing iron production. From the 17th century onwards, pitch furnaces were increasingly used and in the 19th century retorts were also employed ...
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.
