多构型两级冷凝有机朗肯循环系统优化及碳足迹敏感性分析
Optimization of two-stage condensation organic Rankine cycle system with multiple configurations and carbon footprint sensitivity analysis
摘要
Abstract
To enhance the economic efficiency of the cycle,a two-stage interrelated condensation organic Ran-kine cycle configuration is proposed.Compared with the two-stage independent condensation organic Rankine cycle configuration in existing studies,this new configuration is optimized for different working fluids and liq-uefied natural gas(LNG)input pressures with the goal of maximizing the lifecycle revenue,followed by a sen-sitivity analysis of the carbon footprint under uncertainty.The results show that under the design operating con-ditions,the system net power output and lifecycle revenue of the two-stage independent condensing configura-tion outperform those of the two-stage interrelated condensation configuration.When the LNG input pressure is low and electricity generation over the lifecycle is substantially lower than the full-load generation,the two-stage interrelated condensation configuration performs better than the two-stage independent condensation con-figuration,with R143a being more suitable for the two-stage interrelated condensation configuration.When working fluid leakage is considered,the lower-global warming potential(GWP)working fluid R290 offers better carbon reduction.When working fluid leakage is negligible,the higher the net output power of the sys-tem,the more effective the carbon reduction of the system.关键词
