Abstract
The Fengshun geothermal power plant is a single-flash experimental geothermal power plant located in Fengshun County, China. After power generating, the geothermal water is still 72oC with a flow rate of 230t/h. To improve the utilization efficiency of the geothermal water, an integrated cascade utilization system is designed to recovery the geothermal tail water from the geothermal power plant for cooling, agriculture drying and bathing. The test data show that the utilization ratio of geothermal resource is higher than 70%, which includes geothermal bathing of 40.6%, geothermal refrigeration of 23% and geothermal drying of 7.1%.
