摘要
以带有回热器、中冷器、预冷器的高温气冷堆氦气轮机循环为研究对象,用发动机热力计算方法导出循环有效效率表达式和最佳增压比解析式,然后对高温气冷堆氦气轮机循环的热力过程进行分析,揭示了各参数之间的关系。另外,还对回热器、中冷器进行了简要分析并进一步优化,最后得到了一个优化设计方案。结果表明高温气冷堆氦气轮机最经济循环效率可达49.6%。
The performance of closed- cycle helium turbine incorporated with high temperature gascooled reactor（ HTGR） which coupled with recuperating,intercooling and preceoling processes is optimized in this paper. First, the thermal efficiency of the cycle and the optimum boost ratio are derived in the way of calculating of the thermodynamic process. Then, analyzes the thermodynamic process of HTGR gas turbine cycle to show the effects of various parameters on the cycle efficiency. In addition, the recuperator and the intercooler are analyzed briefly and optimized and obtains an optimal scheme. As a result of this paper,the optimum efficiency of HTGR gas turbine cycle can reach 49.6%.
