Fueling the Furnace. Using charcoal to make iron is a process that came to the colonies from England. In the 1770s, when Hopewell Furnace first began making iron, charcoal was the only fuel available. The 19th century, however, brought experiments in the process through the use of hard anthracite coal in place of the softer charcoal.

Uses of Coal. It is mainly used to generate heat and electricity. It is used in s and in industries to accomplish various tasks. It is the cheapest source of power fuel. The iron and steel industry depends heavily on fossil fuel for energy. It is also used to produce useful products such as coke, tar, and coal gas.

Usually, anthracite is preferred for use as blastinjection coal due to its high carbon content. The important role of blastinjection during the ironmaking process is to partially substitute metallurgical coke, reducing the consumption of addition, anthracite can also increase the intensity of smelting and improve the level of raw iron output.

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of 'stealing' the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c.
