Introduction to Level Control and Maintenance of the Integrated Deaerator

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.
