Sažetak
Težnja da se smanji potrošnja fosilnih goriva zbog njihovog nepovratnog iscrpljivanja i velikog zagađivanja životne sredine sve više ističe neophodnost korišćenja obnovljivih izvora energije i uvođenja u praksu novih energetskih tehnologija. Kogenerativna postrojenja (CHP) sa biomasom kao energentom se može svrstati u novije tehnologije transformacije energije u kojima se pored fosilnih goriva koristi i obnovljivi izvor energije. U tim stremljenjima veoma povoljnu i ekonomski isplativu opciju pruža mogućnost da se iz tih postrojenja ka industrijskim korisnicima ili sistemima centralnog grejanja naselja usmeri električna i toplotna energija. U ovom radu je prikazana opravdanost izgradnje kogenerativnog postrojenja (CHP) na biomasu u TE-TO Zrenjanin, koja se nalazi u okviru d.o.o Panonske TE-TO. Usvojeno postrojenje ima produkciju električne energije od 10 MWe sa izlaznom termičkom snagom od 20 MWt, što godišnje obezbeđuje 57% potreba Zrenjanina za toplotom. Sa investicijom od 43.530.810 evra i neophodnošću obezbeđenja 1.400.000 evra obrtnih sredstava, godišnjim prihodima od 9.051.229 evra i troškovima od 4.111.194 evra uz neto sadašnju vrednost projekta od 63.080.447 evra izračunato je da je investicija isplativa i da je treba prihvatiti za realizaciju.
Abstract
A trend towards the reduction of fossil fuel consumption due to their irreversible depletion and environmental pollution is increasingly emphasising the necesssity of renewable source utilisation and the practical introduction of new energy technologies. Cogeneration (CHP) plants using biomass as a primary energy source can be classified as a recent energy transformation technology using both fossil fuels and renewable energy sources. Such plants provide very favourable and cost-effective options for supplying electrical and thermal energy to industrial consumers and district heating. This paper displays the justification of the biomass cogeneration (CHP) plant construction in TETO Zrenjanin, which is a constituent of Panonske TE-TO Ltd. The designed plant generates 10 MWe of electrical energy with the output thermal energy of 20 MWt, which could meet 57% of the total heat requirements in the town of Zrenjanin. With the investment of RSD 43.530.810, the necessity of procuring RSD 1.400.000 of working assets, the annual income of RSD 1.013.737.648, the costs of RSD 460.453.728 and the current project net worth of RSD 7.065.010.064, it has been calculated that the investment is cost-effective and it should be made.
