coal type - anthracite, page-11

Last one for me as these are going into the bottom draw.
therefore No more banging on from me.

"Economic value
Because of its higher quality, anthracite is around 2 to 3 times the cost of regular coal. The regular coal in the above post inc coking.


anthracite delivers high energy per its weight and burns cleanly with little soot, making it ideal for this purpose. Its high value makes it prohibitively expensive for power plant use. Other uses include the fine particles used as filter media, and as an ingredient in charcoal briquettes."
