摘　　要：除氧器是汽轮机发电机组回热系统中重要的辅助设备,除氧器的水位控制与保护直接影响电厂的安全运行。文章介绍了除氧器水位异常波动的原因以及处理措施,采用三冲量调节系统对除氧器水位进行调节,并以允许流速和已知流量计算了管径和溢流调节阀的口径。Deaerator is an important auxiliary equipment in the reheating system of turbine generator unit. Its water level control and maintenance will directly influence the safe operation of whole power unit. The reasons of abnormal water level in the deaerator and the countermeasures have been described in the article. The water level of the deaerator is controlled with a triplicated adjusting system. The diameters of both pipe and overflow valve have been calculated based on allowed flow velocity and known flowrate.
