大型汽轮发电机通风系统研究综述

为满足汽轮发电机不断地向大型化发展地需要，必须对大型汽轮发电机的通风系统进行优化设计，以提高其通风冷却效果。为此，国内外对影响汽轮发电机通风冷却状况的主要因素如冷却介质的流动与传热特性、不同通风系统的通风计算方法、通风系统的结构等进行了一系列理论分析和试验研究，并取得不少具有实际应用价值的成果。在对现有成果的分析和总结的基础上，指出了有待进一步研究之处。

Ventilation systems for large-capacity turbine generators

To meet the demand for the development of large-capacity steam turbine generators, it is necessary to optimize the ventilation system for steam turbine generators in order to increase its cooling efficiency. The main factors influencing the cooling efficiency of ventilation systems, such as characteristics of flow and heat transfer of cooling media, ventilation calculating methods for different ventilation systems and configuration of ventilation systems, have been theoretically analyzed and experimentally studied. On the basis of a detailed analysis and comparison of available results, suggestions on further research and development are made.
