What are the types of coal? | U.S. Geological Survey

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as …

What are industrial fuels?

Eventually at the end of the 1940s petroleum residual fuels commenced to take over from coal-derived fuels for the firing of industrial heating processes. In 1974, the so-called "oil crisis" gave rise to a temporary loss of crude petroleum supplies and also to a considerable rise in oil prices.

Iron in the Industrial Revolution

The Development of the Industry . As the industrial revolution developed, so did the iron industry. A set of innovations, from different materials to new techniques, allowed iron production to expand greatly. In 1709, Darby became the first man to smelt iron with coke (which is made from heating coal).

Steel Production

Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.
