船用燃气轮机一次表面回热器的设计分析

Design Analysis of Primary Surface Recuperators for Marine Gas Turbines

提出了一种新型紧凑式回热器———一次表面回热器(PSR)的设计技术。结合船用ICR燃气轮机一次表面回热器的研发,简述PSR的结构特点及其设计计算的理论依据,并给出了设计算例。研究表明,一次表面回热器具有极高的紧凑性和卓越的换热性能,因而这种先进的热交换装置必将替代那些常规的热交换器,在船用动力装置及先进热工程设施中发挥重要作用。

The design technology of a primary surface recuperator (PSR), a new type of compact heat exchanger, is presented. In conjunction with the development of PSR for ICR (intercooled recuperated) marine gas turbines briefly described are the construction characteristics of PSR and the theoretical basis of its design calculations. Some examples of design calculation are given. The results of a study indicate that the PSR features extremely high compactness and excellent heat exchange performance. Hence, this type of advanced heat exchangers will inevitably take the place of traditional heat exchange units and play a major role in the area of marine power plants and advanced thermal engineering facilities.
