Abstract

This disclosure provides manifolds, manifold components, and heat recover steam generator systems. An output line of an output manifold is fluidically connected to at least one downstream process. A first collection line is fluidically connected to a plurality of header lines by a first set of header links. A second collection line is fluidically connected to the plurality of header lines by a second set of header links. A connecting junction fluidically connects the first collection line and the second collection line to the output line.
