Abstract: In this study, a specific arrangement of thermoelectric modules is presented for energy recovery in the main steam condenser unit of Neka power plant. Thermoelectric modules convert a section of losing energy to electricity with a combination of semiconductor materials. In this study as a result of variation of thermal resistance of condenser pipes, a definite amount of steam entering the condenser is excess that has been checked with design of one steam split line to two systems. A part of steam transferred to absorption chiller and improved the efficiency and also the other sent to desalinate system. It has been shown that with the implementation of this plan, the output of a power plant will increase to 450 MW and power losses of warm days will be saved as much as 11257 MWh.
