Exergy Efficiency Calculation of Energy Intensive Systems by Graphs. Exergy Int

In the design and operation of energy intensive systems the problem of improving its efficiency is very important. The main way to solve this problem is thermodynamic analysis. This paper describes the general approach for calculating the exergy efficiency of complex energy intensive systems with arbitrary structure. A novel general equation of systems exergy efficiency is provided. An example of the method applied to a nuclear power plant analysis is given
