Thread Content
This post was last edited by “Back to Cambridge” on February 27, 2016, at 11:20. Starting today, the Chemical Engineering Theory section will launch the “Question of the Day” activity, aimed at helping everyone reinforce their fundamental knowledge in chemical engineering. Subsequently, series such as “Principles of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also 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! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: Why does the boiler water become cloudy or brown? Answer: The main reasons for turbid boiler water are: 1) Turbid feed water or excessive hardness. The cause of this phenomenon in the feedwater is mainly the high turbidity or hardness of components such as condensed water and make-up water in the feedwater, due to issues like condenser leaks or contaminated make-up water. 2) The boiler is not drained for an extended period, or the amount of drainage is insufficient. 3) At the initial stage of startup for a new boiler or a boiler that has been overhauled. 4) The combustion or water flow conditions are abnormal, resulting in large load fluctuations.

The water quality is too poor or it’s cloudy 1
This is because the calcium and magnesium ions in the boiler water react with carbon dioxide present in the water, forming solid compounds of calcium carbonate and magnesium carbonate, which causes the water to become turbid； The iron on the surface of the boiler steel plates is oxidized by the oxygen in the boiler water, forming iron oxide, which gives the boiler water a light tea-colored appearance.

The phenomenon in the feedwater is mainly caused by the turbidity or high hardness of components such as condensed water and make-up water in the feedwater, as well as issues like condenser leaks and contaminated make-up water. 2) The boiler is not drained regularly, or the amount of drainage is insufficient. 3) In the early stages of startup for a new boiler or a boiler that has been overhauled. 4) The combustion or water flow conditions are abnormal, resulting in large load fluctuations.
1. The boiler feed water is turbid or has too high a hardness! 2. The amount of waste discharged is insufficient or the cycle is too long! 3. The cleanliness inside the furnace is insufficient in the early stages of operation.
