Depends on the engines.
I don't have numbers in Kilos, but...
For a Pratt and Whitney powered 757-200:
average around 3,000 pounds per hour per engine. As little as 2,800 pounds per hour when light. As much as 3,400 pounds per hour when heavy.
For a Rolls Royce powered 757-200:
average around 3,700 pounds per hour. When really heavy, around 4,400 pounds per hour. When really light (ferry flight), around 3,200 pounds per hour.
Rolls burn is much greater, flying at the same mach number (usually mach 0.80)

There is about 500lbs/hr/engine greater burn on the C over the E4.
(We used to have both)
