Thread Content
This post was last edited by “Back to Cambridge” on January 27, 2016, at 15:05. Starting today, the Chemical Engineering Theory section will launch the “Question of the Day” activity to help 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 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! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What are the main functions of the steam-water separation device and the steam cleaning device inside the drum? Answer: To obtain pure steam, high-parameter boilers are equipped with sophisticated steam-water separation devices and steam cleaning systems in their drum. The main function of the steam separation device is to reduce the water carried by saturated steam, thereby lowering the moisture content of the steam – in other words, reducing the mechanical load carried by the saturated steam. A properly designed steam separation device can reduce the moisture content in the steam exiting the drum to 0.01%-0.03%, with a maximum of no more than 0.05%. A steam cleaning device is an effective tool for ensuring steam purity, as it functions to reduce the amount of substances dissolved in the steam.
A steam separator is used to remove moisture from the steam so that it can enter the water volume in the boiler drum. Steam cleaning involves using cleaner make-up water to wash away the salts contained in the steam and deposit them in the water of the boiler drum.
Ensure the quality of the steam, free of water.

What are the main functions of the steam-water separation device and the steam cleaning device inside the drum? A steam separator is used to remove moisture from the steam so that it can enter the water volume in the boiler drum. Steam cleaning involves using cleaner make-up water to wash away the salts contained in the steam and deposit them in the water of the boiler drum. Several cyclone separators are installed on both sides along the length of the drum, with louvered separators placed at the top of each cyclone separator tank. Their main function is to carry out a preliminary separation of steam and water in the steam-water mixture introduced through the rising tubes. In the middle and upper part of the drum, steam cleaning orifice plates are installed horizontally, with a layer of cleaning feedwater above them. When steam passes through this water layer, some of the salts dissolved in the steam or carried by it are transferred back into the water, thereby reducing the salt content in the steam. A perforated plate is located near the top of the drum; it distributes the steam rising within the drum evenly and further separates the moisture from the steam. An emergency drain outlet is located at approximately 150 mm below the centerline of the drum ； 200 mm below the normal water level line, there is a continuous sewage discharge outlet, and below that, a chemical dosing pipe is installed. A cross baffle is also installed at the inlet of the downcomer to prevent vortex formation at the downcomer outlet, which could cause vapor to enter the downcomer.
