摘　　要：基于一维集中参数法和一维流动、完全传热、两相热平衡三条基本假设,对带轴流式预热器蒸汽发生器进行稳态分区建模。使用FORTRAN 95语言编制了相应的计算程序并对其进行验证。证实计算值与参考值吻合较好后,对带轴流式预热器蒸汽发生器的稳态热工水力特性进行分析,并研究了轴流式预热器结构参数对稳态热工水力特性的影响。Based on one-dimensional lumped parameter method and the assumption of one-dimensional flow, complete heat transfer and two-phase thermal equilibrium, the steam generator with an axial economizer is divided into several regions. A comparatively complete analysis model and corresponding algorithm routine has been set up at each region. Afterwards, a one-dimensional steady-state thermal-hydraulic calculation code is programmed with Fortran 95 language. The verification and validation results of the code show that the model and algorithm routine are rational. At last, the steady-state thermal-hy- draulic performance of steam generator with an axial economizer has been analyzed, and the influence of the structure of the economizer has also been investigated.
