Evaluation of Heat Rates of Coal Fired Electric Power Boilers

Improvements to heat rate are one means to reduce the emissions of carbon dioxide (CO 2) from coal-fired power plants. Heat rate is the amount of heat input from fuel per unit of net power output. Because heat rate is the inverse of efficiency, a lower heat rate signifies a more efficient electric generating unit.
