ABSTRACT:
Process and equipment serving for the utilization of geothermic energy. In the course of the process water is introduced in a vapor producing pipe driven into the rock under the terrain and by making use of the geothermic heat, water is evaporated and the vapor is utilized such as for the generation of electrical energy. A superatmospheric pressure is set in the vapor producing pipe and a liquid (heat carrying medium) is let to trickle down in the tube, the saturated vapor of which contains 1000 kJ/m.sup.3 of latent heat of evaporation at the adjusted superatmospheric pressure. The equipment includes a vapor producing pipe embedded in the rock under the terrain, a liquid feeding device connected to the upper end of the vapor producing pipe as well as a device to serve for transforming the energy of the extracted vapor. The liquid feeding device comprises a distribution vessel, in which there is an annular spillway directing the liquid in a film-like layer on the inner surface of the vapor producing pipe and enclosing the opening of the distribution vessel ending in the vapor producing pipe.
