摘要
介绍了核电汽轮机的参数低、采用节流调节、蒸汽湿度大以及增设汽水分离再热器等特点,并分析了产生这些特点的主要原因;其次论述了汽轮机与反应堆的容量匹配以及各种出力的概念。核电本身的特点是造价高、运行费用低、无温室气体排放,为了充分发挥核电的特长,反应堆与汽轮机采用零裕量匹配。各种出力的概念也与常规火电有所不同。最后深入讨论了核电汽轮机的选型以及全速机与半速机在经济性和可靠性各方面的比较。
First described were such features of nuclear power plant turbines as low parameters,adoption of throttling regulation,high steam wetness and additional installation of MSRs(moisture separator and reheater)etc.and analyzed were the main generation causes of these features.Subsequently,the capacity matching and concepts of various capacities were expounded.The features of nuclear power plants themselves include:a high manufacturing cost,a low operation cost and absence of greenhouse gas emissions.To allow full play to the merits of nuclear power plants,the reactor and steam turbines adopt a zero allowance matching.The concepts of various capacities are different from those of conventional coal-fired power plants.Finally,the type selection of steam turbines for use in nuclear power plants and comparison of full-speed turbines and semi-speed ones in terms of cost-effectiveness and reliability were discussed in detail.
