Blast Furnace Coal Injection

  • Cupola furnace

    Cupola furnace

    Cupola furnaces were built in China as early as the Warring States period (403–221 BC), although Donald Wagner writes that some iron ore melted in the blast furnace may have been cast directly into the Han Dynasty (202 BC – 220 AD), most, if not all, iron smelted in the blast furnace was remelted in a cupola furnace; it was designed so that a cold blast injected at the bottom ...

    The effect of different auxiliary fuel injection on the blast furnace's operation is examined. Compared to pulverised coal injection, hydrogen injection leads to the formation of a much larger raceway, m 3, which is about four times the raceway volume of pulverised coal injection under the simulation conditions. This may be ...

    Energy Use in US Steel Manufacturing

    Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron is often known as "pig iron" or "hot metal" as it is a liquid iron that flows from the bottom of the blast furnace.

  • Coking Coal

    Coking Coal

    Gulhan Ozbayoglu, in Comprehensive Energy Systems, 2018. Coal is used in iron and steel industry. Coking coal is an essential input for production of iron and steel. The largest single use of coal in the steel industry is as a fuel for the blast furnace and for the production of metallurgical coke for reduction of iron ore or for injection with the hot blast.

    Pulverized Coal Injection (PCI) coal. Used in steelmaking, but it is not indispensable like met coal. It is a softer, noncoking coal which is pulverized and injected into the blast furnace to supply heat, which in return reduces energy use and emissions. It does not play a role in the ironsteel conversion, and cannot replace hard coking coal ...
