Background
In the process of boiler feed water treatment, oxygen removal is a very critical link. Oxygen is a main corrosive substance of a water supply system and a boiler, and the oxygen in the water supply should be quickly removed, otherwise, the oxygen can corrode the water supply system and parts of the boiler, iron oxide which is a corrosion product can enter the boiler, deposit or attach on the wall and the heated surface of the boiler to form iron scale with poor heat transfer, and the corrosion can cause pit on the inner wall of the pipeline, so that the resistance coefficient is increased. When the pipeline is seriously corroded, the pipeline is frequently burst. The water loss in the system operation needs to be done by low temperature softened water as the water supplement, and the water is sent into the system after deoxygenation, but because the deoxygenation effect is not very good due to the low temperature, an external mixed heater or a raw water heater is generally arranged as the water supplement preheating device, so that the vibration is larger, and more space is needed.
