METHOD FOR PREVENTION OF SCALE FORMATION IN PROCESS OF GEOTHERMAL WATERS ENERGY UTILISATION Russian patent published in 2009 - IPC F24J3/08 

FIELD: power engineering.

SUBSTANCE: method includes transfer of thermal energy of geothermal water through intermediate heat exchangers to secondary coolant, separation and collection of gases dissolved in geothermal water by means of primary and secondary separators and gas holder, and also use of potential energy of geothermal water by means of converter in the form of expander, compressor and pump installed on the same shaft.

EFFECT: method makes it possible to utilise energy of geothermal water in mode without scale formation in expander and primary separator due to supply of condensate part from secondary separator, acidified with carbonic acid gas from gas holder, to lower stages of expander and primary separator.
