Apstrakt

U termoelektranama sa starijim projektnim rešenjima postoji značajan potencijal za iskorišćenje otpadne toplote dimnih gasova. Otpadna toplota dimnog gasa se može iskoristiti primenom zagrejača vode visokog pritiska (ZVVP) i niskog pritiska (ZVNP). U ovom radu je razmatrano rešenje sa ZVVP koji se napaja vоdоm sа pоtisnоg vоdа nаpојnе pumpе parnog bloka termoelektrane na ugalj, kao i primena ZVNP koji se napaja kondenzatom iz linije kondenzata niskog pritiska. U cilju poređenja energetskih efekata primene ZVVP i ZVNP, usvojene su iste površine oba razmenjivača. Minimalna temperatura kondenzata na ulazu u zagrejač vode je ograničena pojavom niskotemperaturne korozije. Povećanje električne snage na generatoru bruto ugradnjom ZVVP je 2,5 puta veće nego u slučaju sa ZVNP, a povećanje stepena korisnosti bloka bruto ugradnjom ZVNP je za 20% veće nego sa ZVVP. U radu su predstavljeni efekti ugradnje ZVVP koji se napaja hladnom napojnom vodom u termoelektrani "Nikola Tesla B".
