GT13E2 FSR (Front Stage Ratio) Concept


Thread Starter


Good afternoon everyone,

I want to request some support in order to understand a concept in a GT13E2 Alstom Gas Turbine.

The operation manual explain that the FSR (Front Stage Ratio) is defined as the ratio of the front stage group gas mass flow to the total mass flow. Its operation depends of the relative load and the Tk1 in order to control emissions and combustion stability.

Could somebody share some documentation in order to get a better understanding of this parameter?
