摘要
液化天然气(LNG)是一种应用日趋广泛的清洁能源,构建LNG冷能低温动力循环成为回收冷能的重要途径。本文首先讨论了LNG侧参数、循环工质、设备进出口参数等重要参数对基本LNG冷能动力循环的影响;其次分析和总结了诸多LNG冷能动力循环的结构改进类型,包括朗肯循环、布雷顿循环、卡琳娜循环和复合循环。文章最后指出了参数研究的实际工程意义和循环结构改进的多样性,并指出下一步研究应围绕有机混合工质组分配比、模拟与实验相结合等方面展开。
Liquefied natural gas is an increasingly widely used clean energy. Establishing cryogenic power generation cycles using LNG cold energy is an important way of cold energy recovery. In the present paper,the key factors affecting the basic LNG power generation cycles are discussed,including LNG-side parameters,working fluids and equipment inlet and outlet parameters. Cycle structural enhancement is also summarized,including Rankine cycle,Brayton cycle,Kalina cycle and the compound cycles. The practical significance of parametric study and diversity of cycle structural enhancement are indicated. It is also pointed out that further research should be based on the selection and the component matching of organic mixed working fluids,and the combination of simulation and experiment,etc.
