Subbituminous coal coal classification BritannicaSub Bituminous Coal Characteristics The Balance
Due to environmental concerns an increasing number of coal fueled electric power plants have switched from burning bituminous coal to subbituminous coal and lignite which also tends to have a relatively low sulfur contentSub bituminous coal is noncoking and contains less sulfur but more moisture approximately 10 to 45 percent and volatile matter up to 45 percent than other bituminous coal typ It has 35 to 45 percent carbon content and its ash content ranges up to 10 percent The coal s sulfur content is generally less than 2 percent by weight Nitrogen makes up approximately 05 to 2 percent of the
