中文摘要	介绍了一种新型的内管为螺旋管的管套管式双面加热直流蒸汽发生器。为编写稳态换热分析程序建立了一种固定二次侧焓值边界计算模型。该模型依据二次侧流体相的变化,将蒸汽发生器划分为三个分区:单相液区、两相区和单相汽区。程序的计算结果与文献中实验结果吻合较好,并从计算结果分析得出了该蒸汽发生器的一些结构参数对换热效果的影响规律。; A new type of double-side heating steam generator with helical tubes inside is presented and recommended in this paper. And an immovable enthalpy boundary model is developed. According to phase transformation of the fluid in the SG's secondary side, the model divides it into three parts: the water single-phase region, the boiling region and the steam single-phase region. The program based on the model is developed . We obtained a good agreement between its prediction and the experimental result, and get some useful rules for the OTSG.
