Methodology for analysis of harmonized district heating and natural gas systems development in our towns

Abstract

More than 40 towns in Serbia, connected to gas net work supply system, also have present district heating systems, which in most cases use natural gas as fuel. Since, building of parallel systems, for supplying the same consumers, is techno-economically unjustifiably and energetically not rational, it is necessary to investigate harmonization of both systems development, with goal to achieve optimal techno-economic effects of such systems. This paper analyses possibilities of harmonized development of gas supply and district heating systems in our towns, considering investment and exploitation costs of both systems.

U Srbiji je u preko 40 gradova, priključenih na magistralni gasovodni sistem, izgrađen sistem centralizovanog snabdevanja toplotnom energijom (toplifikacioni sistem) koji u najvećem broju slučajeva koristi kao gorivo prirodni gas. Imajući u vidu da je tehno-ekonomski neopravdano i energetski neracionalno graditi paralelne centralizovane sisteme snabdevanja istih potrošača neophodno je istraživati usaglašenost razvoja oba sistema u cilju postizanja optimalnih tehno-ekonomskih efekata centralizovanog sistema snabdevanja energijom. U radu se u tom cilju analizira mogućnost usklađenosti razvoja toplifikacionog i gasovodnog sistema u našim gradovima imajući u vidu specifičnosti investicionih i eksploatacionih troškova oba sistema.
