Heating in thermal deaerator

In a thermal deaerator, the relationship between the water temperature and the amount of heating steam is crucial. This is because they directly affect the performance of the deaerator. 1. Water temperature: Theoretically, raising the water temperature helps oxygen to escape from the water. Especially after the heated water comes into contact with steam, it can more effectively remove oxygen and other dissolved gases. 2. Amount of heating steam: This is a key factor; if there isn’t enough steam, it’s not possible to bring the water to the designed high temperature, which in turn affects the deoxygenation effect. On the contrary, if there is an excess of steam, it will waste energy and may cause damage to the equipment. The specific parameters and design schemes need to be calculated and designed based on the type, scale, and operating conditions of the equipment, which usually involves many complex physical and chemical principles. For professional information in this area, you can refer to relevant engineering manuals or textbooks, such as the \"Thermal Engineering Handbook,\" or you can consult professional engineers. Remember, any changes require appropriate testing to ensure safety and effectiveness. Before making any changes, you should consult an engineer with expertise. .

It’s best to look at the instructions for this deoxygenation device; they can help explain your question for reference.

There are many books on water treatment and boiler water treatment on the forum, and the boiler operator’s manuals also cover deaerators. The original poster can search for and download it (such as “Questions and Answers on Boiler Water Treatment Technology”). It is necessary to determine the steam consumption: first, consult the technical specifications of the deaerator, and then record the volume and temperature of the water entering the deaerator, as well as the temperature of the water exiting it (for medium and low pressure boilers, this is usually 102°C). Additionally, the temperature and flow rate of the saturated steam should be recorded. Check the corresponding enthalpy value again to verify the thermodynamic calculations. (There are also many discussions on calculation methods**tans; you can search for them.) Energy conservation is necessary, and the waste steam discharged from the deaerator can be collected by spraying desalinated water. (Keyword: waste steam recovery) Interestingly, many people working with boilers assume that the energy consumption associated with the steam used by deaerators is already accounted for. In fact, the deaerator raises the temperature of the demineralized water and recovers a large portion of the heat energy in the steam, so its impact on the thermal efficiency of the boiler is not that significant. (This is how some manufacturers of deoxidizers calculate it.)
