The influence of temperature on geothermal power plant performance based on geology in Huangshadong geothermal field, China

The geological structure is rather complicated in Guangdong province, China. 10 deep fault belts are mainly oriented NE. NE good channels for thermal energy upwelling, which can form a geothermal water reservoir zone. heating of atmospheric precipitation and surface by rocks the primary formation mechanism hydrothermal resources Huangshadong field. results show that two-stage conversion system flash-binary more reasonable when geofluid temperature higher than 130oC. With every 10oC increment system, power output exergy efficiency increase 21.6-38.7% 6.0-13.1% respectively. will decrease about 20-40% cooling arising from 15 to 25oC. research provide basic data demonstration resource exploitation.
