Ask the steam turbine experts!
Thread Content
May I ask all the steam turbine experts?: I recently read a book about steam turbines, and I didn’t quite understand the section about the control stage! Excuse me: 1. What is the function of the steam turbine control stage? 2. I went to the site and inspected the equipment. The control level is in front of the steam inlet. Why does the steam still advance to the control level? 3. What is the process of steam in the turbine? I wonder if any expert can explain it in detail. I would be very grateful. In addition, if anyone has a daily maintenance inspection list for steam turbines and compressors, can they provide the next copy? Thank you! ! !
Why doesn't anyone give an answer? Heroes, please!!!
Please explain in detail the specific model of steam turbine you are using (it is best to have pictures so that everyone can help you). There are a lot of training materials in the forum. I hope it will be helpful to you!!! The following one is good.: http://bbs.hcbbs.com/viewthread.php?tid=118592&page=1&extra= This post was last edited by Lu Junrang on 2008-2-2 10:40 ]
The steam turbine control stage usually refers to the steam inlet mechanism of the steam turbine, which is controlled by the actuator oil motor of the speed control system. After the steam turbine starts and reaches the working speed of the governor, the steam turbine control stage controls the speed of the steam turbine so as not to overspeed and cause an accident. When the steam turbine reaches its rated speed and is connected to the grid, the steam turbine control stage plays the role of controlling and regulating the load. The steam enters the nozzle after advancing to the turbine control stage, and flows into the moving blade to produce power.
The control and regulation system, including induction, amplification, steam distribution and other mechanisms, regulates the air intake of the turbine.
