  • Bituminous Coal Characteristics and Applications

    29.01.2020· Bituminous coal contains the mineral pyrite, which serves as a host for impurities such as arsenic and mercury. Burning the coal releases trace mineral impurities into the air as pollution. During combustion, approximately 95 percent of bituminous coal's sulfur content gets oxidized and released as gaseous sulfur oxides.

    fixed carbon content of subbituminous coal ranges between 46% and 60% and has a heating value of 8300–13,000 Btu/lb. Typically, subbituminous coal contains less sulfur, resulting in ''cleaner'' burning. Higherranked coals (bituminous coal, anthracite) are generally harder and stronger, and often have a black vitreous lustre.

  • World of an Entrepreneur: Specific Gravity

    Specific gravity is a number indicating how many times a certain volume of a material is heavier than an equal volume of water. The density of water differs slightly at different temperatures, so the usual custom is to make comparisons on the basis that the water has a temperature of 62°F. The weight of 1 cubic inch of pure water at 62°F is 0.0361 pound. If the specific gravity of any
