In order to better solve the problem of making up water for oxygen removal,this paper discusses the key technology of vacuum thermal oxygen removal.Combined with the principle and key links of thermal deaeration,the measured data of deaeration of a 300MW unit are analyzed.It shows that the condenser can be competent for the task of making up water and removing oxygen.When the unit makes up a large amount of water,multiple functional areas need to be optimized to a certain extent.
