A case study on the Balçova-Narlidere geothermal district heating system

Turkey is among the first five countries in abundance of geothermal resources around the world so geothermal energy is an important renewable energy resource in Turkey.In this study, following a general information concerning geothermal energy, it is specified in tables that the direct and indirect utilization of the geothermal resorces in Turkey and its established capacities at the present day are given. Direct utilization of geothermal energy focuses on district heating system and is implemented in 21 geothermal field. The biggest and the most important of all is that of the one in the Balçova-Narlıdere geothermal field. Concerning the Balçova-Narlidere district heating system, the general evaluation of the geothermal field, its historical development, geothermal wells, the total residence capacity, an evaluation of the system, price comparison with the other fuels, and the environmental factors are all discussed.Finally, the Narlıdere district heating system stage-3 project in Balçova-Narlıdere geothermal field is presented under the headings of geothermal loop, city loop and building loop. Each building situated in stage-3 is specified one by one and the total peak field and the total peak load are deducted and 3D design of the heating system is worked on.
