How can burning 2,000 pounds of coal yield more than 4,000 pounds of carbon dioxide? When coal is burned, the carbon in the coal combines with oxygen to form carbon dioxide. One molecule of carbon dioxide is times heavier than a molecule of carbon, due to the additional weight of the two oxygen atoms. Coal is not 100 percent carbon ...

from flue gases produced by the combustion of coal. Instead of being discharged directly to the atmosphere, flue gas is passed through equipment which separates out most of the CO 2. The CO 2is fed to a storage reservoir and the remaining flue gas is discharged directly to the atmosphere (IPCC, 2005). Flue gases or stack gases in coal ...
