Abstract: In this paper, feed water heating repowering of Shahid Montazeri steam power plant has been studied in three differentmodes. Efficiencies of energy and exergy have been selected as objective functions. Cycle-tempo softwarewas used for simulations. In the first case, a low pressure heat recovery heat exchanger and a EGT-RLM600-PCgas turbine were used. Efficiencies of energy and exergy increase to 3.8% & 3.79% respectively and cooling towerwater temperature difference increases to 0.652oC. In the second case, a high pressure heat recovery heat exchangerand a Siemens (KWU) V64.3 gas turbine were used. Efficiencies of energy and exergy increase to 6.68%and 6.65% respectively. In the third case, both heat recovery heat exchangers are and Westinghouse-401 gasturbines were used. Efficiencies of energy and exergy increase to 8.93% & 9.05% respectively. This is the bestplan in terms of efficiency and cycle power promotion.
