摘要
目前我国大多数火力发电厂都采用湿冷技术,面对日益紧缺的水资源问题,火力发电行业面临前所未有的挑战,而空冷技术与普通湿冷技术相比可节水2/3,因此近几年空冷技术得到广泛应用。本文以2*600MW空冷机组为例介绍了直接空冷系统的工艺、特点及控制方案。
As air cooling systems designed to minimize water consumption and energy usage, in recent years many air cooled steam turbines have been operated in north China. This paper introduces the technology, features and control solution ofa 2＊600MW supercritical coal fired power unit.
