中文摘要	高温气冷堆具有900~1 000℃的出口温度而使其具备采用联合循环发电的潜力。在典型高温气冷堆氦气-蒸汽联合循环中,氦气回路多采用预冷器等设备以降低压气机入口温度和压缩功,但这也使反应堆的入口温度过低而影响联合循环效率的进一步提高。为提高循环效率,对联合循环中的预冷器对循环效率的影响进行了热力学分析,提出了联合循环中是否需设置预冷器的判据,并根据这一判据提出了一种简化型联合循环,即无预冷器的联合循环。简化型联合循环的优化结果表明,在950℃的反应堆出口温度下,其循环效率可达52.2%,较典型联合循环的效率提高了1.4%,较回热循环的效率提高了1.7%。与回热循环相比,在反应堆出口温度较高而其入口温度要求较低的工况下,简化型联合循环更具有优势。; High temperature gas-cooled reactor(HTR)is of a potential of using combined cycle to generate electricity due to high reactor core outlet temperature of 900-1 000 ℃.In a typical combined cycle of HTR,aprecooler was used to reduce the compressor inlet temperature and the compression work,while it also lowers the reactor core inlet temperature and hinders the further improvement of cycle efficiency.To improve cycle efficiency,the influence of precooler on efficiency of the combined cycle of HTR was analyzed theoretically.And a criterion was deduced to determine whether a combined cycle of HTR adopts a precooler based on the analysis.A simplified combined cycle system without precooler was proposed based on the criterion.The optimizationresults show that the efficiency of the simplified combined cycle is 1.4% higher than that of the typical combined cycle and 1.7% higher than that of the recuperative cycle with reactor core outlet temperature of 950 ℃.Compared with the recuperative cycle,the simplified combined cycle is more competitive in work conditions with high reactor core outlet temperature and low reactor core inlet temperature.
