摘 要
本文以白山热电有限责任公司300MW汽轮机的冷端系统为例，全方位论述了胶球系统收不球的原因及凝汽器热负荷高的原因，科学的研究了冷端系统的优化。针对胶球系统收不到球，凝汽器端差较大，低加疏水系统不能逐级自流，危急放水保持开启方面的问题，逐项采取了有效的措施和手段，对胶球系统及低加疏水系统进行了大规模的改造，解决了困扰汽轮机冷端系统的两个问题，降低了凝汽器端差，低加疏水系统在高负荷可以实现逐级自流，对提高汽轮机的效率及新技术应用的推广具有明显的现实意义和经济意义。
关 键 词：汽轮机冷端系统；胶球；低加；改造；应用

Title: Hakusan 300MW Thermal Power Unit Co., Ltd.Rubber Ball system and retrofits of low-drain system.
ABSTRACT
In this paper, Hakusan Co., Ltd.300MW Steam Turbine Thermal cold end system as an example. Discusses the full range of plastic ball system does not receive the ball heat load causes and reasons for the high condenser. Scientific research of the cold end system optimization. System for the rubber ball not receive the ball. Condenser-side difference larger. Not one level of low gravity drain system. Critical issues remain open drainage One by one taken effective measures and means On the rubber ball system and the low-drain system on a large scale transformation. Solve the problems of steam turbine cold end of the two issues. Difference lower condenser. Low-drain system can be achieved step by step in the high gravity load. To improve turbine efficiency and the promotion of new technology has obvious practical and economic significance.
