Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering,\" \"Mass Transfer and Separation,\" \"Thermodynamics in Chemical Engineering,\" and \"Chemical Process Engineering.\" We hope you will give it your active support! Wishing you a happy Christmas! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying to the post, and the topic will be closed after 1 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: From an operational perspective, how can the deoxidation efficiency of a deaerator be ensured? Answer: 1) Deoxygenated water should be heated to its boiling point; pay attention to adjusting the amount of steam and water to ensure that the water in the deaerator remains in a boiling state ； 2) The exhaust from the deaerator should be unobstructed ； 3) The amount of make-up water should be stable; it should flow into the deaerator in a continuous and even manner, without interruptions, and large amounts of make-up water should not be introduced suddenly ； 4) The water distribution in the deaerator must be even, so as to provide the water with sufficient surface area for mixing with the heating steam; this ensures that the required heat is available for deoxygenated water and helps to facilitate the rapid separation of oxygen from the water.
Supply steam from the bottom of the deaerator; it is sufficient to maintain a pressure of 0.02 Mpa in the deaerator and a water temperature above 110°C.
From an operational perspective, how can the deoxidization efficiency of the deaerator be ensured? Answer: 1) Deoxygenated water should be heated to its boiling point; pay attention to adjusting the amount of steam and water to ensure that the water in the deaerator remains in a boiling state ； 2) The exhaust from the deaerator should be unobstructed ； 3) The amount of make-up water should be stable; it must flow into the deaerator in a continuous and even manner. Intermittent supply is not suitable, nor is it acceptable to inject a large amount of make-up water suddenly ； 4) The water distribution in the deaerator must be even, so as to provide the water with sufficient surface area for mixing with the heating steam; this ensures that the required heat is available for deoxygenated water and helps to facilitate the rapid separation of oxygen from the water.

From an operational perspective, how can the deoxidization efficiency of the deaerator be ensured? Answers: 1. The deoxygenated water should be heated to its boiling point; attention must be paid to adjusting the amounts of steam and water to keep the water in the deaerator in a boiling state. 2. The exhaust from the deaerator must flow smoothly. 3. The amount of make-up water supplied should be stable; it should enter the deaerator continuously and evenly, without interruptions, and large amounts of make-up water should not be added suddenly. 4. The water distribution within the deaerator must be even, so that the water has sufficient surface area for mixing with the heating steam, thereby ensuring that the necessary heat is provided for deoxygenation and allowing oxygen to be removed from the water quickly.
This series is excellent! 1. Deoxygenated water should be heated to the boiling point; pay attention to adjusting the amount of steam and water to ensure that the water in the deaerator remains in a boiling state ； 2.
