耦合型超临界CO2布雷顿循环热力学分析
Thermodynamic analysis of coupled supercritical CO2 Brayton cycle
摘要
Abstract
Based on the characteristics of supercritical CO2 Brayton cycle,a coupled supercritical CO2 Brayton cycle was obtained.The accuracy of the coupled supercritical CO2 Brayton cycle was verified according to the cycle principle and the mathematical model.Through thermodynamic comparison and analysis of cycles,the influence laws of turbine inlet temperature,condensing temperature,turbine inlet pressure,turbine outlet pressure,mass shunt ratio,precompression pressure and reheat pressure on cyclic thermal efficiency,thermal efficiency and net work volume were obtained.The optimal value exists in the influence of turbine outlet pressure,shunt ratio,precompression pressure and reheat pressure on cyclic thermal efficiency,they are 7.9 MPa,0.35,8 MPa and 15 MPa,respectively.关键词
