Abstract

Pogon EL-TO je kogeneracijska elektrana za proizvodnju električne energije i topline. Sadašnje jedinice su pri kraju svog vijeka, ne zadovoljavaju nastupajuće ekološke propise. Imaju nisku učinkovitost u proizvodnji električne energije, a lokacija troši nekvalitetno tekuće gorivo. Lokalna zajednica zahtjeva prestanak te prakse. Ovaj rad analizira stanje postrojenja EL-TO, preostali životni vijek jedinica, perspektivu pogona u strateškim dokumentima energetskog razvoja te mogućnost izgradnje zamjenskog novog kombi kogeneracijskog bloka na lokaciji kao mogućnosti smjera razvoja lokacije. Analizira se zadovoljenje kriterija na lokaciji, mogućnost evakuacije toplinske i električne energije, mogućnosti dobave plina, mogućnosti zadovoljenja ekoloških propisa, mogućnosti fizičkog smještaja na lokaciji. Kao osnovno otvoreno pitanje prepoznaje se neriješen problem hlađenja novog bloka što onemogućava kondenzacijski rad i usložnjava i poskupljuje izvedbu novog bloka. Analiziraju se moguća rješenja tog problema u skladu sa položajem lokacije u Zagrebu i raspoloživim prostorom. Zaključuje se da za novi kombi kogeneracijski blok na lokaciji EL-TO postoje preduvjeti u vidu mogućnosti smještaja, postojanja toplinskog i električnog tržišta, mogućnosti evakuacije električne energije, mogućnost poboljšanja ekoloških uvjeta, te da se takav blok dobro uklapa u strateške dokumente Republike Hrvatske i Europske Unije. Lokacija je analiziran po pitanju iskoristivog toplinskog konzuma te je zaključeno da je od 7 lokacija termoelektrana u RH, lokacija EL-TO najizglednija za izgradnju ovakvog visokoučinkovitog bloka. Uvidom u napravljene dijagrame toplinskog konzuma zaključeno je da bi angažman ovakvog bloka mogao biti 5000h i više, ovisno o odabranoj snazi. - KLJUČNE RIJEČI:

Abstract (english)

EL-TO power plant is a cogeneration plant for production of electricity, district heating and industrial steam. Installed units are near te end of their useful lifetime. They do not fulfill ecological obligations. They have low efficiency in production of electricity. They use low quality liquid fuel, a praxis that the local community is trying to stop. This work analyses state of EL-TO units, their useful lifetime, perspective of EL-TO power plant in strategic energy documents of Republic of Croatia and the possibility of solving the problems of the location by building a new, combined cycle cogeneration power plant. Physical integration, possibilities of evacuation of electrical and heating energy, natural gas availability and compliance with ecological regulations are analyzed. Lack of any cooling system for a new block is recognized as a fundamental question. Work in the condensing mode for a new block is thus impossible, and any solution to that problem will be expensive. Different solutions are analyzed, regarding the position of EL-TO location in Zagreb and available space. The conclusion is made that preconditions for building a new, CCCGT power plant in EL-TO Zagreb, as a part of the development of the location are fulfilled. There is enough space, there is a market for electricity and heating, there is a possibility for evacuation of electricity, improvement in fulfillment of ecological standards will be achieved. Such block fits well into strategic documents od RH and EU. All 7 locations of HEP d.d. are analyzed and it is concluded that the location EL-TO has best prerequisits for building such unit. Load diagrams were created and it is evident that the potential for work of such a power plant exeed 5000 hours annually.
