Abstract
Disclosed are a system for extracting heat from hot unrefined water for the purpose of using this heat to do useful work, and specifically for extracting such heat while minimizing the undesirable effects caused by formation of scale and other solid build-up of scale-forming impurities in the hot unrefined water. Before contact with a heat exchange surface the hot unrefined water has added thereto an agent capable of increasing the formation of non-scale-forming species of said scale-forming impurities. These agents may be added immediately before passing the hot unrefined water through heat exchange equipment and/or directly into a geothermal well.
Claims8
A system for extracting heat from hot unrefined water containing scale-forming impurities comprising:
- a source of said hot unrefined water;
- a heat exchange means having an entrance end and an exit end;
- means for conveying said hot unrefined water from said source to the entrance end of said heat exchange means;
- a detention receptacle for receiving cooled unrefined water from the exit end of said heat exchange means;
- and means for separating and extracting a dispersion of precipitated particles of said impurities from said cooled unrefined water in said detention receptacle, and recycling said dispersion to said hot unrefined water at a point prior to its entry into said heat exchange means.
