The Modified Productive Structure Analysis of Afyon Geothermal District Heating System for Economic Optimization

Ali Kecebas

Abstract


This study deals with exergetic and exergoeconomic analysis of geothermal district heating system (GDHS) which offers nowadays many disadvantages in the aspect of high heat losses and costs. The Afyon GDHS located in the city of Afyonkarahisar/Turkey is selected as a case study. The modified productive structure analysis (MOPSA) is used for exergy-cost evaluation. In these analyses, mass and energy conservation laws are applied to each component of the system. Quantitative balances of the exergy and exergetic cost for the whole system and its each component is carefully considered. The results show that about 52.49% of the input cost of the Afyon GDHS is lost from the heat exchangers, 16.26% from pipes, and 7.22% from pumps. The heat exchangers and their efficiencies should be improved as high as possible to decrease the system costs. The unit cost of heating from geothermal water in the Afyon GDHS is about 711.491 US$/h at 100% load conditions.
