It calculates the exergy loss of 2 sets of typical regenerative systems(200MW 600MW)by the software MathCAD

based on the generalized exergy loss distribution matrix equation of regenerative systems of coal-fired power unit; then compared with the results which calculated by the traditional calculating methods. Furthermore

the application methods of the equation and the usage skills are introduced in detail. Again

exergy analysis of the results is made to find out the potential of the energy saving. Then 4 kinds of exergy analysis indication were compared through the bar graphs to prove that the exergy loss ratio and the exergy loss coefficient could represent the perfect degree of the regenerative systems.
