中文摘要 | 针对100 MW电功率的氦气透平直接循环的设计,对循环各个部件分别进行热力学第一和第二定律分析。给出了各个部件的输入和产出Exergy公式,计算了Exergy损失分布,并与按照传统分析方法获得的分析结果进行了比较。结果表明:一半以上的Exergy损失发生在堆芯部分,而由预冷器、压气机和间冷器组成的压缩系统所占Exergy损失比重比按照第一定律计算的能量损失份额小得多;循环Exergy损失主要原因是能量形式的转换和不可逆换热。系统Exergy效率略高于热效率。; According to the design of 100 MW HighTemperature Gas-Cooled Reactor coupled with gas turbine,the energy and Exergy analysis were carried out for each part of the cycle,and inlet and outlet Exergies of those parts were calculated.The Exergy loss distribution and Exergy loss ratio of each sub-process were quantified and compared with the results of energy analysis.The results show that more than a half of the Exergy loss takes place inside the reactor core,while the compress system composed of low and high pressure compressors as well as the intercooler play a much smaller role in the contribution of Exergy losses than the results in the energy analysis.The Exergy loss of the cycle is mainly due to the energy conversion and irreversible heat exchange.The total energy efficiency of the cycle is quite high,and the Exergy efficiency is higher.; 国家“863”计划资助项目(2003AA511010); 国家自然科学基金资助项目(90410001) |
