Question

Difference between anthracite and bituminous in energy

Answer 1

Corrected Question: Anthracite (“hard”) coal vs Bituminous (“soft”) coal. Anthracite is a hard mineral coal, cleaner & hotter burning, lower pollutant contaminants, typically with a shiney surface like flint or obsidian.

Bituminous coal is “soft” (literally) in the sense that it will easily leave streaks when drawn against other materials, higher in sulphur and other contaminants that cause pollution if burned without controls. Looks like charcoal.

Answer 2

Anthracite has highest heating value and burns without smoke which makes it suitable for domestic use whereas Bituminous calorific value is very high due to high proportion of carbon and low moisture content.

I HOPE IT IS SUFFICIENT AND HELP FOR YOU.
