Geothermal Aided Power Generation (GAPG) technology is a geothermal hybrid power system that energy has been integrated into the fossil fired plant to preheat feedwater, and displace extraction steam of plant. In such system, heat exchange process between geo-fluid occurs in between. When exchanger quench lower temperature for transfer purpose, silica scaling would occur system. The performance...

In an effort to tap the vast geothermal resources of the western United States, Secretary of Energy Bill Richardson and U.S. Senator Harry Reid of Nevada recently announced a DOE initiative to expand the production and use of energy generated from heat within the earth. The new initiative is known as GeoPowering the West. During a news conference on Capitol Hill, Secretary Richardson also annou...

The conditions of heat source and heat sink in a geothermal ORC system may frequently vary due to variations in geological conditions, ambient temperature and actual operation. In this study, an off-design performance prediction model for geothermal ORC systems is developed according to special designs of critical components, and an optimal control strategy which regards the turbine guide vane ...
