Brown Coal vs Black Coal Comparison: Differences

Jul 05, 2019Black coal is many millions of years older than brown coal and has a lower water content. Black coal has a heat content of approximately 35300 kJ/kg where as brown coal has a heat content of approximately 28470 kJ/kg, depending on the water content. Unlike black coal, brown coal must be dried before it is burnt. – dynamicscience.au.

Mining Process

Sixty million years ago, the area where BNI now mines coal was a vast swamp. Plants died, fell into the water and decayed slowly. Eons later, the climate changed and rivers deposited material over the decaying vegetation. The weight of the overlying material pressed the vegetation into lignite seams. Geologists believe it took about 10 feet of decaying vegetation to form one foot of lignite.

Types of Coal

Since lignite coal is the young form of coal, it has the lowest heating value and relatively high moisture content. As a result, the amount of carbon in lignite is low. Lignite coal is best known for power (electricity) generation and is believed to be about 17% of the world's coal reserves.

Lignite coal in North Dakota

Lignite coal made homesteading possible in frigid winter weather in western North Dakota. The region had little timber to heat with, and in the early 1900s, lignite was the main fuel.
