The first surface and the second surface are surrounded by a perimeter defining an edge. A first plurality of holes extend through the impingement plate. A plurality of protrusions extend outward from one of the first surface or the second surface and have a distal surface transverse to one of the first surface or the second surface. At least one second impingement hole extends through the distal surface.
