Closed-loop geothermal power generation system with turbine engines

摘要

A geothermal power generation system configured to generate power by suspending turbine engines over a pit exposing a geothermal energy source is disclosed. The geothermal power generation system may include a support structure sized to a pit and at least one turbine engine hanging below the support structure. One or more turbine engine deployment systems may be configured to move the turbine engine, i.e. raise or lower, such that a distance between the turbine engine and the geothermal energy source changes. In one embodiment, the turbine engine deployment system may be formed from a plurality of cables extending from a rotatable cable drum on the support structure and downward from a plurality of pulleys positioned along the pulley track. The support structure may also include a pulley track extending from the first base to the second base. One or more electrical transmission lines may extend from the turbine engine.

主权项

1. A closed loop geothermal power generation turbine, comprising:
a turbine housing forming at least one internal cavity; a generator positioned within the turbine housing; a rotor blade assembly positioned within the turbine housing and in communication with the generator via a drive shaft; a boiler in communication with the rotor blade assembly; a condenser positioned within the turbine housing and in fluid communication with at least one exhaust outlet of the rotor blade assembly and the boiler; at least one check valve positioned between the condenser and the boiler; and wherein the at least one check valve extends circumferentially around the rotor blade assembly.
