Abstract
An Organic Rankine Cycle(ORC) experimental system for low-temperature flue gas heat recovery was constructed. R123 was selected as the working fluid of the experimental system, and low-temperature flue gas produced by stove was treated as heat source to imitate the flue gas from industrial furnaces. The relationships among output power of expander, cycle efficiency and exergy efficiency and system parameters were researched. The results show that the output power of expander increases with the increase of evaporating pressure and temperature of heat source. The maximum of output power of expander efficiency is 645 W. The cycle efficiency increases with the increase of evaporating pressure and the maximum of cycle efficiency is 8.5%. The exergy efficiency increases with the increase of evaporating pressure and temperature of heat source. The maximum of exergy efficiency is 3.5%. Increase of the superheat degree has a bad influence on system performance.
