300MW直接空冷汽轮机的结构特点

The Design Features of 300 MW Direct Air-cooling Turbine

鉴于空冷技术的广泛运用,空冷汽轮机相继投入运行。概述了300MW空冷汽轮机系统结构,并简要对直接空冷原理及流程进行了说明,分析了300MW直接空冷汽轮机与湿冷汽轮机在结构、系统方面的差别,以便为300MW空冷汽轮机的安全运行提供帮助。

Because of the wide application of the air-cooling technique, the various air-cooling turbines have been put into the operation one after another. This paper expounds the system structure of the 300 MW direct air-cooling turbine, introduces the principles and technological processes of the direct air-cooling, and analyzes on the differences of the 300 MW direct air-cooling turbine and the wet cooling gas turbine in the structure and the system, which provides the help for the safe operation of wet cooling gas turbine.
