ABSTRACT The steam generator steam‐water separator is one of the critical components, with increasing demands on its performance and operating cost. To improve the separation efficiency of the corrugated plate steam‐water separator and reduce the operating cost, a novel corrugated plate steam‐water separator is proposed in this study. The optimization effect of the novel corrugated plate steam‐water separator is analyzed through numerical simulation methods. The main results are as follows: By comparing the separation performance of two types of corrugated plate separators, the separation pressure drop of the novel separator is significantly reduced. Moreover, the pressure drop decreases progressively with increasing inlet velocity, with a maximum reduction of approximately 40%. While reducing the separation pressure drop, the separation efficiency of the novel corrugated plate steam‐water separator remains at the same level. Considering the presence of secondary droplets, the structure of the drainage hook is modified to alter the droplet flow trajectory of large‐diameter droplets, adjust the liquid film distribution, and reduce the generation of secondary droplets. The method of graded optimization of the drainage hook structure provides a reference for the structural optimization of corrugated plate steam‐water separators.
