W skraplaczach energetycznych generowane są jedne z największych strat strumienia entropii w instalacji energetycznej. Celowe jest obniżanie tej straty, aby uzyskać poprawę całkowitej sprawności instalacji. W artykule podano warunek dla minimum generacji strumienia entropii, z którego wynika, że minimum to jest osiągnięte, gdy podgrzew wody w rurkach skraplacza ma równomierny rozkład (przyjmuje taką samą wartość dla wszystkich rurek). Poprawność tego warunku sprawdzono na podstawie danych uzyskanych z symulatora 2D skraplacza dla jednego z krajowych bloków o mocy 50 MW. Na podstawie otrzymanych z symulatora przyrostów temperatur oraz odpowiadających im ciśnień pary dla 30 rurek dokonano oceny poprawności konstrukcji skraplacza.

The losses in power plants condensers are some of the biggest losses in the entropy generation in whole power plant system. It is advisable to decrease the loss for improving the overall efficiency of the system. The article presents the condition for the minimum entropy generation, which states that the minimum is achieved when the heating of the water in the tubes of the condenser has a uniform distribution (takes the same value for all tubes). The correctness of this condition was verified on the basis of data obtained from the 2D condenser simulator for one of the national units with a 50 MW electric capacity. On the basis of the simulator increases temperatures and steam pressures corresponding to 30 tubes assesses the correctness of the construction of the condenser.
