摘要

以大型聚光太阳能热发电电站等比例尺寸的熔盐蒸汽发生器为研究对象

采用集中参数法进行网格处理

通过控制体积法和高斯-赛德尔方法离散求解控制方程

建立管壳式换热器结构耦合熔盐-水/蒸汽相变流动换热的熔盐蒸汽发生器热预测数值计算模型。分析不同两侧流量及流动对传热特性的影响。结果表明

熔盐流量是蒸汽发生器总换热系数及效能的主要影响因素

熔盐流量越高

总换热系数越高且效能越低。基于剧烈相变位置的分析

建议使用熔盐从蒸汽发生器尾端流入的结构设计。

Abstract

Regarding the proportional-scale molten salt steam generator for concentrating solar power plants

the lumped parameter method

along with the control volume method and the Gauss-Seidel method

is simultaneously employed to establish a numerical model for predicting its thermal performance by considering the heat and mass transfer phenomena of molten salt-to-water/steam phase change in a shell-and-tube heat exchanger. The influence of different flow rates and flow patterns on heat transfer characteristics is analyzed. The results indicate that the molten salt flow rate is the primary factor affecting the overall heat transfer coefficient and effectiveness of the steam generator. Higher molten salt flow rates lead to an increased overall heat transfer coefficient but reduced effectiveness. Based on the analysis of the intense phase change locations

it is recommended to adopt a design where the molten salt enters from the tail end of the steam generator.
