On the basis of analyzing physical cold exergy of LNG (liquefied natural gas) the authors have proposed a low grade heat source based cryogenic power system for recovering LNG cooling energy. An investigation was conducted of the relevant parameters having an impact on the system cycle efficiency. The results of the investigation show that under a relatively low heat source temperature the thermal and exergy efficiency of the system may attain in excess of 30%. From an analysis of the cycle influencing main parameters it is ascertained that the condensing temperature of secondary cooling medium exercises a very great influence on the cycle efficiency. With the increase in evaporation temperature and the decrease in condensation temperature there will be an enhancement of both the cycle thermal efficiency and exergy.
