AI Technical Summary
Geothermal ORC systems face flash corrosion and scaling problems under high temperature and high pressure conditions. Existing technologies, which use flash tanks for pretreatment, result in high maintenance costs, system complexity, and low thermal efficiency.
By monitoring the geothermal water temperature in real time and dynamically controlling the pressure of the ORC system to ensure it is always higher than the saturation pressure of the geothermal water, flash evaporation is avoided. The pressure is adjusted using a PID control algorithm, eliminating the need for equipment such as flash tanks.
It effectively prevents flash corrosion and scaling, improves system stability and power generation efficiency, reduces operation and maintenance costs, reduces environmental risks, and enhances the overall thermal efficiency of the system.
