Water Injection Pump for GE Turbine

A

Thread Starter

Ayed

we are planning to install nox control (water injection) in GT frame 7001E. we have two option in the water injection for NOX control system pump configuration

1- either to install pump with VFD
2- Or pump with constant speed and bypass control valve

We know that the water injection flow rate is not constant flow due to operational condition. so, VFD modulates the frequency of the power supply of the motor thus flow rate will be adjusted according to the demand. so which one is reliable VFD or bypass control valve?

waiting your feedback
