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 hard coal, containing a high ...

Sintering emissions and their mitigation technologies

The CO 2 emissions from sinter plants vary widely over time and between sinter plants as a consequence of variations in fuel inputs, fluxes, and other feedstock, especially in the types and quantities of iron-bearing materials that are recycled. Figure 18.1 shows the CO 2 and CO concentrations measured in the waste gas during a sinter pot test on a typical East Asian sinter blend.

Anthracite coal is consumed mostly in Pennsylvania and its surrounding states. The largest use of anthracite is for space heating. Lesser amounts are employed for steam/electric production; coke manufacturing, sintering and pelletizing; and other industrial uses. Anthracite currently represents only a small fraction of the total quantity

What is the difference between pellet and sinter?

2.2 Comparing Sinter and Pellets Sinter is a clinker-type iron bearing material that is produced when a mixture of iron ore fines known as sinter feed, finely ground fluxes, carbon (coke breeze or anthracite) and various recycled iron bearing materials are uniformly fired along a continuous traveling grate reactor.
