ABSTRACT:
A heat exchanger feed system and method for distributing fuel through the walls of a combustor or other heat exchanger formed by a plurality of tubes each having first and second ends and adjacent tubes being connected to form an air-tight structure. A first series of the tubes are bent out of the plane of the wall to form a cylindrical passage extending at an angle to the wall through which material can flow. Each of the tubes in the series comprises a first vertical portion extending upwardly from the first end, a first diagonal portion extending upwardly from the first vertical portion and outwardly from the wall at an angle from the vertical, a second diagonal portion extending upwardly from the first diagonal portion and inwardly towards the wall at an angle from the horizontal, and a second vertical portion extending upwardly from the second diagonal portion to the second end. The passage is formed by bending the second diagonal portion of each of the tubes in the first series outwardly from the centerline of the inlet to form the passage.
