| Popis: | During the heat transfer, due to temperature differences, a share from the heat exergy content is destroyed. Consequently, the use of heat exchangers in thermodynamic cycles declines their efficiencies. The paper presents an original model for computing the exergy destruction during the heat transfer in a superheated steam generator. The model was applied for a Concentrated Solar Plants with molten salt in the primary circuit. The results show that, in given boundary conditions, and for an imposed heat exchange surface, there is a pressure which maximizes the steam-generator exergy efficiency. The heat transfer surface growth lead to raising both the transmitted exergy and the optimum steam pressure. |
