I have been looking for engine specifications for different engines and I find most of the information, but the one thing I cannot find is the fuel flow rate.

Can any of you engine techs tell me the fuel flow rate in LBS/Hr or Kgs/Hr for the following engines?

CFM56-3B1 @ 20,000lbs thrust (B737-300)
CFM56-7B24 @ 24,200lbs thrust (B737-700)

Thanks so much

Are you looking for FF rate in climb, cruise or descent?

Maintain 2300 until Boiler, cleared for the VOR-A approach, report BATLE inbound..

Sorry about that, I guess knowing which would help

What I'm looking for is the FF rate for: 1 engine, at sea-level, standard temperature and pressure. In other words, manufactures specs. I found some for the CFM56-7B20-see below for an example-but not the -7B24.


Engines: CFM56-7B20

Stabilized Idle Indications, ISA conditions, Sea Level, CFM56-7
N1 RPM - 20%
N2 RPM - 59%
EGT - 410°C **
Fuel Flow - 272 kg/hour

** Idle EGT may vary from 320°C - 520°C depending on OAT, bleed configuration and engine
