What are the necessary conditions for heating deaeration in a deaerator?
Thread Content
The two necessary conditions for heating and deoxidizing water in a deaerator are as follows: (1) The feedwater must be heated to the saturation temperature at the rated pressure of the deaerator; (2) The gases that separate and escape from the water must be removed promptly. If the first condition is not met, the gas cannot be completely separated from the water ； When the second condition is not met, the gas that has separated will return to the water. The process of gas separating and escaping from water cannot be completed in an instant; it requires a certain amount of time for the gas to separate.
Therefore, a necessary condition for deoxidation by heater heating in the deaerator is also that the duration be long enough to ensure that as many gases as possible are separated and removed from the water. At the same time, it is also necessary to ensure that the pressure and flow rate inside the deaerator are appropriate, in order to facilitate the separation and removal of gases. The fulfillment of these conditions can effectively remove oxygen from water, improving the deoxygenation effect of the feedwater. .
