Description

Technical Field

[0001] The utility model belongs to the technical field of deaerators, and in particular relates to an energy-saving thermal deaerator for a steam boiler. Background Art

[0002] Many deaerators often use steam heating to heat water to discharge oxygen in the water. However, steam heating is often performed as a whole under the water or on the outer surface of the water. As a result, the water source closest to the steam is heated quickly, while the rest of the water is heated slowly. After the oxygen in some water sources is discharged, the steam needs to continue heating the water sources in other locations, which will cause water source loss. At the same time, the uneven heating and deoxygenation at various locations will also increase the deoxygenation time, thereby increasing the steam heating time and reducing practicality. For this reason, we propose an energy-saving thermal deaerator for steam boilers. Utility Model Content
