Coal Drying Improves Performance and Reduces Emissions

power plant, less coal needs to be fired. This reduces the burden on the coal handling system, conveyers and crushers. Also, since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system.

Climate Change: Global Temperature Projections

Results from a wide range of climate model simulations suggest that our planet's average temperature could be between 2 and 9.7F (1.1 to 5.4C) warmer in 2100 than it is today. The main reason for this temperature increase is carbon dioxide and other heat-trapping "greenhouse" gases that human activities produce.
