Does anybody have a ballpark number for the fuel flow of a GE90-115B at TRT and sea level?

Based on what I know about the CFM56's fuel flow and multiplying to get equal thrust, I would guess that it is around 40,000-45,000 lb/hr. Does anyone have firsthand experience with this?

You get the exact value here, it is part of the ICAO engine emission databank, You need to convert to imperial units though:

Off a copy of a flight plan that I have , for a 77W at MTOW the burn from sea level to FL39 cruise was 8332kg over a time of 30-mins. The Boeing 77W load/range chart is based on the -115BL I believe it is.

From ferpe's link, the published takeoff fuel flow was 4.690 kg per second. Multiply by 3600 to get kg/hr gets you 16,884 kg per hour. Convert that to pounds and you end up with about 37,144 lbs/hour takeoff flow for a GE90-115B.
