Estimating carbon dioxide emissions from coal plants
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.
