The (arithmetic) average emission factors obtained from the individual samples (assuming complete combustion) (Table FE4) (10) confirm the longrecognized finding that anthracite emits the largest amount of carbon dioxide per million Btu, followed by lignite, subbituminous coal, and bituminous coal.
What Type Of Coal Is Best For Blacksmithing?Called brown coal due to its woody texture and similarity to peat, lignite is the softest coal. It's the lowestranking because it holds the highest amount of sulfur and nonburnable minerals among all the coal types. Lignite is either stripmined or mined in open pits. Most Texas coal is lowgrade lignite used in electric power plants.

Estimating carbon dioxide emissions from coal mines ...Apr 29, 2021 · Carbon dioxide emission factors are not necessarily lower for higher quality coals. For example, anthracite coal, which is the highest quality coal, produces more carbon dioxide per Btu than lowquality lignite. This is because anthracite lacks hydrogen, which is a small portion of the content of lower grade coals.
