Fuel gas requirements for aeroderivative gas turbines

Once considered an occasional “necessary evil,” fuel gas booster (FGB) compressors in turbine power generation facilities have become a common requirement. FGBs are installed because of insufficient gas pressure onsite or from nearby utility gas pipelines.

Historically, pressures up to 300 psig (~20 barA) were adequate for most industrial gas turbines and were often available onsite or at an economical distance. But modern gas turbines tend to run at much higher compression ratios, thus raising the inlet fuel gas pressure requirement.
