We Need Western Coal - SENAA West

Sen. Conrad Burns, R-Mont., was the luncheon speaker. The conference is examining the role of low-rank coals - like lignite, brown and subbituminous coals - which have a lower heat content because they have less carbon, higher moisture and greater impurities than other types of coals. switched from bituminous to subbituminous coal and

COAL -- A Fossil Fuel

Subbituminous coal has a higher heating value than lignite. Subbituminous coal typically contains 35-45 percent carbon, compared to 25-35 percent for lignite. Most subbituminous coal in the U.S. is at least 100 million years old. About 44 percent of the coal produced in the United States is subbituminous. Wyoming is the leading source of

Uses and Properties of Bituminous Coal | Future Libraries

Bituminous coal – IspatGuru

Sep 17,  · Bituminous coal contains the mineral pyrite, which serves as a host for impurities such as arsenic (As) and mercury (Hg). Burning the coal releases trace mineral impurities into the air as pollution.
