闪蒸-双工质联合发电系统热力性能比较
Thermal performance comparison of flash-binary power system
摘要
Abstract
To select a suitable working fluid for flash-binary power system(FBPS),a thermodynamic model for FBPS was established. In this calculation,the heat source temperature of the FBPS is 100—150℃ with a flow rate of 36t/h and cooling water inlet temperature is 15℃. Five organic working fluids(R236fa、R600a、R600、R245fa、R601a) were selected to analyze their work capacity based on the performance index of net power output per ton of geofluid,thermal efficiency,exergy efficiency and irreversible loss of the system. Finally,the best working fluid was determined. Results showed that the net power output of FBPS increases with the increase of flash temperature and then decreases. Each working fluid has an optimum flash temperature which makes the net power output to be maximum. Taking environmental and thermodynamic performance into consideration,R245fa is the best working fluid for the flash-binary power system.关键词
