Estimating carbon dioxide emissions from coal plants ...
· Formula. The CO 2 emissions from a proposed coal plant can be calculated with the following formula: . annual CO 2 (in million tonnes) = capacity * capacity factor * heat rate * emission factor * x 10^12 . Example for a typical coal plant Size: 1,000 MW; Capacity factor: 80%; Supercritical combustion heat rate: 8863 Btu/kWh; Subbituminous coal emission .
