Abstract
Abstract Natural gas can be used for satisfying population needs for heating, either directly by bringing the gas to the dwellings through the gas distribution system and combusting it in the domestic boiler (gas distribution system—G) or indirectly by combusting the natural gas in the heating plant and distributing the heat energy to the dwellings through the district-heating (DH) system. The selection of a certain type of heating system is made according to the disposition of buildings in the area, their number, size, insulation quality, etc. Based on these characteristics, calculations of investments and exploitation costs have been made for both heating systems and a comparison has been made for all of the 96 presented cases. Almost each type of real settlement can be represented by one of the types of the conditional urban area that are introduced in the paper. The main goal of this paper is to establish a general model to achieve coordinated development of centralized energy supply systems fueled by natural gas, based on defined and accepted criteria. A structure analysis of centralized systems for energy supply has been done with accent on their pipelines.
Highlights
If a gas based system in a settlement is planned, the decision can be done among two conflicted options: 1. Indirect system; natural gas is being combusted in a heating plant and household heat supply is provided by a District Heating System (DH), 2
The G system is another form of energy which is being distributed for domestic heating purposes
- District heating system is a better option in areas with small built up density, but with skyscrapers. -Gas system is a better option in areas with high density of individual houses
