Deaerator Copper Nozzle M24 D6.5, Flow Rate 0.6 T/H; M32 D9.5, Flow Rate 1.6 T/H The primary function of a deaerator is to remove oxygen and other non-condensable gases from boiler feedwater to ensure water quality. If dissolved oxygen is present in the water, it can cause corrosion of metal surfaces in contact with the water. Additionally, the accumulation of gases in heat exchangers increases thermal resistance, reducing heat transfer efficiency. Therefore, the presence of any dissolved gases in water is detrimental, particularly oxygen, which poses a direct threat to the safe operation of equipment. In thermal power plants, thermal deaeration is employed. The deaerator itself also serves as a mixing heater within the feedwater regenerative system. Meanwhile, drains from high-pressure heaters, chemically treated makeup water, and other high-quality high-pressure drains and steam vents from across the plant can be collected into the deaerator for reuse, reducing steam and water losses in the power plant. The working principle of the deaerator involves the main condensate (including makeup water) from the low-pressure heater, regulated by an inlet control valve, entering the deaerator and mixing with other drains. The mixture is then sprayed through nozzles or perforated pipes, forming an umbrella-shaped water film. This film undergoes mixed heat and mass transfer with rising heating steam, rapidly bringing the feedwater to the saturation temperature corresponding to the operating pressure. At this stage, the majority of dissolved oxygen and other gases are released, achieving the purpose of deaeration.
