Issues regarding turbine-driven centrifugal compressors
Thread Content
The main steam temperature and pressure of the turbine are within normal ranges, and its speed remains unchanged; however, the steam flow rate to the turbine has decreased for some unknown reason, resulting in an increase in pressure in the upstream system. Could someone explain why this is happening?
Has the load on the compressor decreased? If so, less steam will be used
There was no artificial reduction in the compressor load; when it was observed that the amount of steam used by the turbine was low, it was found that the volume of air entering the compressor also decreased
The turbine side must be scaled.........................
Has the compressor load changed?
How should this be understood? ? ? ? ? ? ? ? ? ? ? ? ?
Check whether the compressor is in the unloaded state. The greater the load, the more steam is used
How to understand scaling at the turbine end? What kind of impact will it have?
Looking at the trends, the steam volume to the turbine has been fluctuating over this period, with the variation in steam volume being around one ton
A decrease in steam volume definitely means a reduced load on the compressor
Are there any other reasons besides reduced load that could cause this phenomenon?
