Technical Field

Because oxygen in boiler feed water can corrode boiler equipment, so that the boiler equipment is perforated, a water supply system of the boiler can be corroded, corrosion products can enter the boiler and deposit or adhere on the wall and the heated surface of the boiler to form iron scale with poor heat transfer, pits can be formed in the inner wall of a pipeline due to corrosion, the resistance coefficient is increased, and even pipe explosion accidents can occur when the pipeline is severely corroded.
The principle of the boiler water supply deoxidizing device is mainly thermal deoxidization. The thermal deoxidization is to introduce steam with a certain pressure into water and heat the water to a boiling state, so that the solubility of oxygen dissolved in the water becomes small due to the temperature rise, thereby achieving the purpose of deoxidizing the boiler feed water. However, the water temperature is higher (generally about 104 ℃) after thermal deoxidation, the required steam quantity is larger, and the waste of steam can be caused.
As disclosed in the patent issued to CN 218115052U, a thermal deaerator comprising: deoxidizing water tank, deoxidizing tower and atomizing feed pipe. The deoxidizing water tank is used for heating the water inside to generate steam, and the steam heats the incoming water supply to 104 ℃ in the deoxidizing tower, so that dissolved gas escapes from the water. The deaerator can remove oxygen in water supply, but has higher water temperature after deaeration, larger steam consumption and higher cost.
