A combined energy recovery system which comprehensively uses both low-temperature waste heat and liquefied natural gas(LNG)cold energy was proposed.This system can realize better temperature matching of different cycles and cascade utilization of the waste energy.Thermodynamic laws were adopted to analyze thermal performance of the system.Also
parametric analysis was performed to evaluate the effects of key factors on the system performance.The results show that this proposed system exhibited good performance
which can achieve the net electrical efficiency and exergy efficiency of 39.4% and 47.33%
respectively.The system performance was influenced by both the state parameters and mass flow rate of working fluids
and the competition between both effects determined the overall system performance.
