Thread Content
This post was last edited by “Back to Cambridge” on February 19, 2016, at 15:51. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: How can the phenomenon of \"temporary disappearance of salts\" in boiler water be prevented? Answer: 1) Improve the boiler’s combustion conditions to ensure a uniform heat load across some of the furnace tubes ； Prevent coking and slagging in the furnace, and avoid excessive local load on the furnace tubes. 2) Improve the flow conditions of the boiler water inside the boiler tubes to ensure the proper operation of the water circulation. 3) Improve the chemical dosing process in the boiler to limit the phosphate content in the boiler water, such as by using low-phosphate or balanced-phosphate treatment methods.

How to prevent the “temporary disappearance of salts” in boiler water? 1. Improve the combustion conditions of the boiler to ensure a uniform heat load across all the furnace tubes, thereby preventing scaling and slag formation inside the tubes. Avoid excessive local heat load on the furnace tubes. 2. Improve the flow conditions of the boiler water inside the boiler tubes to ensure the proper operation of the water circulation. 3. Improve the chemical dosing process in the boiler to limit the phosphate content in the boiler water, for example by employing low-phosphate treatment. 4. Reduce deposits inside the boiler tubes and improve their cleanliness.
1. Improve the combustion conditions in the boiler to ensure even heating across all surfaces. 2. Improve the flow conditions of the boiler water to maintain proper water circulation. 3. Adjust the amount of chemicals added to the boiler water. 4. Reduce deposits inside the boiler
When the load on a drum boiler increases, certain soluble sodium salts in the boiler water precipitate out and deposit on the walls of the furnace tubes, resulting in a significant decrease in their concentration in the boiler water. When the boiler load decreases or the boiler is shut down, the sodium salts deposited on the tube walls dissolve again, causing their concentration in the boiler water to rise once more. This phenomenon is known as \"temporary disappearance of salts\".
