摘要

The method for the feed of geothermal energy is carried out by the use of a shaft (2) on an existing power station location (1) and which is dug for a temperature necessary for the condensate preheating and steam production in the power plant. The supplied geothermal energy can be delivered in an open or closed system. The working substance is guided down on the walls of the shaft and is evaporated at the bottom of the shaft. For improved heat transfer grooves are made on the shaft walls.
