  • Geothermal fluid Part of the extracted geothermal fluid is taken to the evaporator of the ORC cycle and another part to the energy storage system, depending on the needs of the demand. It should also be noted that only the minimum amount of geothermal fluid necessary to evaporate the amount of organic fluid that the ORC cycle is currently conducting is directed to the evaporator. And that, on the other hand, when the level of electrical demand decreases, the geothermal fluid that is not required in the organic cycle is taken to the storage system so that it transfers the thermal energy it carries to the water.

  • Geothermal fluid All the fluid extracted geothermal is driven to the evaporator of the ORC cycle. There its mission is only to begin part of the evaporation process that the organic fluid completes upon receiving energy from the storage system.

These two factors are determined by the area in which drilling is performed for the extraction of the geothermal resource and are, therefore, factors limiting the amount of electrical energy that the plant can generate.
  • the choice of R245fa refrigerant fluid was chosen because, for a temperature of the geothermal resource between 100 ° C and 140 ° C and a flow rate close to 75 kg / s, yields are achieved of the ORC cycle very high.
  • a turbine In addition to the organic fluid, another critical element in the generation of electrical energy of the plant, is the turbine.
  • a turbine as known, is a fluid machine that allows energy transformation of the fluid that passes through it in rotary movement of an axis. In this way, coupled to the rotor of a generator, it is capable of transforming fluid energy into electrical energy.
  • the turbine also has to satisfy two not very frequent requirements in this type of machines: First, when the fluid that passes through the turbine is in a gaseous state, the turbine is usually either steam or gas. However, in this case a special fluid, R-245fa refrigerant, has been chosen, so a standard design turbine would not be valid for this project.
  • the turbine must work correctly in a wide range of flows, since this is the way in which the plant modulates the amount of electrical energy generated, transferring a greater or lesser amount of organic fluid through the turbine. Therefore, the use of a multi-stage variable speed turbine for the R-245fa refrigerant fluid is contemplated.
  • Figure number 1 Shows a scheme of the geothermal plant object of the invention, in which the main parts and elements that integrate it are appreciated, distinguishing in said scheme the three differentiated parts of its productive process: the organic cycle of Rankine , the circuit associated with the geometric resource and the energy storage system.
