Abstract: Based on the thermodynamic exergy analysis, the mathematical expression of boiler exergy efficiency was established. For a selected condition, the exergy loss and the exergy efficiency of a 600MW ultrasupercritical boiler were calculated. The calculation shows that the exergy analysis method can reflect various losses and their happening position of power plant boiler more comprehensively. In order to tap the potential of energy conservation and to enhance the economical efficiency of the boiler, the measures for decreasing the exergy loss were put forward.
