Abstract
A fuel delivery system for a gas turbine engine that delivers fuel to a combustor of the engine and lubricates bearings of the engine with fuel, comprising: a tank for storing the fuel; a pump for delivering a continuous flow of fuel from the tank to the combustor by way of a combustor inlet stream and the engine bearings by way of a bearing lubrication stream; a pressurized container for storing fuel lubrication additive under pressure; and a flow valve for controlling flow of fuel lubrication additive that flows from the pressurized container into the bearing lubrication inlet stream to mix with the fuel delivered to the engine bearings.
