What does Steam Turbine Flow Factor at HP First Stage refer to? It may not matter, but I am looking at a standard GE Steam Turbine used in a 7FA 2 on 1 combined cycle configuration.
The term meaning depends on what the writer is saying.
Most tg's have steam bypass valving to deal with changes in load. So the term may refer to the percentage of incoming steam used to generate power, or to the turbine efficiency.
It is a term with double meanings, so you have to track it down.
This may be of help:
