The steam flow rate to the turbine is abnormally high
Thread Content
With the Aunuba flow meter in use, there have been no significant changes in operating conditions or other parameters such as vacuum level. However, the steam flow rate has recently increased by nearly 10 tons compared to before, while there have been no major changes in turbine vibration levels. Please help analyze the reasons; from which aspects should we start investigating? Thank you.
Compare it with the water volume in the condenser to see if the water amount has also increased.
Check if there is a problem with the flow meter
Our condensate flow meter is inaccurate, and there’s no noticeable improvement, yet no problems can be found with the meter itself
Check whether the process load is too high or if the composition is too heavy, etc
Have there been any changes in steam pressure and temperature before? ? ?
To add, it’s possible that the impulse stage and the first and second stages are short-circuited; there is a steam passage the size of a hair strand, usually located on the horizontal sealing surface.
