摘要

In this paper we proposed two novel thermal cycles based on Brayton cycle and Rankine cyclerespectively, which integrate low-level waste heat recovery and Liquefied Nature Gas (LNG) cold energyutilization for power generation. Through the system synthesis, low-level waste heat, low-temperature exergy andpressure exergy of LNG are utilized efficiently. The simulations are carried out using the commercial Aspen Plus10.2, and the results are analyzed. Compared with the conventional Brayton cycle and Rankine cycle, the twonovel cycles bring 60.94% and 60% respectively in exergy efficency.
