| 摘 要： | 对ORC利用工业锅炉烟气余热发电系统进行经济性评估,采用不同换热器结构,对不同工质和余热温度下ORC系统净输出功、单位装机容量投资成本、发电成本和投资回收年限进行对比分析。结果表明,随着烟气流量和温度的增大,系统投资回收年限减小;以采用R123和FS换热器组合(管翅式蒸发器与壳管式冷凝器组合)时经济性最优,单位装机容量成本为23 800元/kW,单位发电成本为0.285元/kWh,投资回收年限为5.58年,净输出功为91.5kW;采用SS(蒸发冷凝器均为管壳式换热器)换热器组合时,经济性最差。热经济分析表明,R123最适合作为ORC利用工业锅炉烟气余热发电系统的工质。

| Abstract: | In this paper,thermo-economic evaluation of organic Rankine cycle power generation system driven by industrial boiler waste heat is carried out. In particular, the effects of different heat exchanger configuration, working fluids and heat source temperature on net power output (Wnet), electricity production cost (CEPC), investment cost per power output (CCPR) and payback period (PPPD) are compared and analyzed. The results show that the PPPD decreases with heat source temperature and mass flow rate increasing. The heat exchanger configuration FS (finned tube heat exchanger as evaporator and shell and tube heat exchanger as condenser) performs efficiently and has the best economic benefit, which gives CCPR 23 800 RMB/kW, CEPC 0.285 RMB/kWh, PPPD 5.58 years and Wnet 91.5 kW, while the economic benefit of heat exchanger configuration SS (two shell and tube heat exchangers as evaporator and condenser) is the worst. From economic point of view, R123 is the best working fluid for organic Rankine cycle power generation system driven by industrial boiler waste heat. |
