Use of geothermal energy to produce electricity and heating at average temperatures

摘要

The paper presents the possibility of using geothermal energy for electricity production at average temperatures. The authors considered two options for their study, namely binary cycles (organic Rankine and Kalina) and the thermoelectric generators. After a comparative study for the proposed solution, was chosen Kalina cycle and was proposed a solution for a geothermal power plant. The advantages are based on the fact that in Oradea exists an important geothermal water reservoir at average temperatures, which can be used to successfully implement the solution for obtaining electricity in small electrogeothermal power stations presented by the authors. This solution is among the newest in the field of geothermal waters at average temperatures.
