Effects of Mill Performance on Unburnt Carbon in Coal

Theoretically, the mass flow of coal can be more uniform by increasing the coal fineness (i.e. decreasing coal particulate size). This is because finer coal particles have a lower inertia, and are more influenced by the gas flow when in suspension [9, 10]

Antithyroid effects of coal-derived pollutants

Thus, antithyroid effects may be greatly amplified by exposure to multiple coal-derived goitrogens and could be many times that produced by any one of the contributing pollutants. These results demonstrate that potent water-borne goitrogens are derived from coal and shale and that their contamination of water supplies could pose a serious
