When coal is burned due to combustion that is more or less completed the result is different levels of energy (B.T.U.'s), and different levels of air emissions (Sulfur Dioxide - SO2, Mercury - Hg), greenhouse gases (Carbon Dioxide CO2, Nitrogen Oxide - NO3), and amounts of ash that can potentially be toxic dependent on the conditions within the combustion chamber and ash that can or can not be used in a secondary market (ex.
