I am working as maintenance engineer in power plant with GE 7FA Turbine. We have facing problems with the Exhaust frame blower. Its taking 120% current during start up and after turbine loading its going down to its design range.
Is this any thing to do with its impeler and volute position?
It is also having high vibration.
