提出了一种利用液化天然气（LNG）冷能和低温余热的新型冷电联供系统。该系统由吸收式制冷/动力循环（阿普）和LNG制冷/动力循环（LRP）两个子系统组成。将朗肯循环和吸收式制冷循环串联起来构成阿普，两者在集成中表现出相互增强的特点。对系统的运行性能进行了计算和分析。分析了发生器压力和循环比对性能的影响。最后，以该系统作为LNG预处理和功率增强装置集成到燃气-蒸汽联合循环系统中为例进行了应用研究。结果表明，该系统的净发电效率、能量综合利用率和火用效率分别达到32.70%、81.63%和35.14%。论证了联合循环燃气涡轮机集成系统的可行性和性能。并对参数设计提出了建议。
A novel combined cooling and power (CCP) system utilizing liquefied natural gas (LNG) cryogenic energy and low-temperature waste heat was presented. The proposed system consists of two subsystems, absorption refrigeration/power cycle (ARP) subsystem and LNG refrigeration/power cycle (LRP) subsystem. The Rankine cycle and absorption refrigeration cycle were connected in series to form the ARP and they showed mutual enhancement in the integration. The operating performance of the system was calculated and analyzed. And the effects of generator pressure and circulation ratio on the performance were analyzed. Furthermore, a typical application case, in which the proposed system is integrated into the gas-steam combined cycle system as an LNG pre-processing and power enhancement unit, had been studied. The results showed that the net power generation efficiency, comprehensive energy utilization ratio, and exergy efficiency of the proposed CCP system reached 32.70%, 81.63%, and 35.14%, respectively. The feasibility and performance of the integrated system with combined cycle gas turbine were proved. And suggestions for the parameter design were presented.
