How it works
(1) Oil flow path
The oil flows through the tube bundle where, by thermal conduction, it releases its calories to the fuel tubes. The temperature range at the oil outlet is -40 deg.F (-40 deg.C) to 367 deg.F (186 deg.C).
(2)Fuel flow path.
- The fuel flows inside the fuel tubes and takes away the heat released by the oil.
If the differential pressure between the inlet and the outlet of the matrix is more than 14.5 psi (100 kPa):
- the pressure relief valve opens,
- the fuel flow bypasses the matrix and returns to the fuel tank via the FRV.
And since you know how this system works, let me show you how to replace one of the lead
