Abstract
A distribution system for injecting reductant into an exhaust duct of a power plant comprises a first injection grid comprising a first manifold and a first plurality of distribution branches, and a second injection grid comprising a second manifold and a second plurality of distribution branches, wherein the first plurality of distribution branches is interleaved with the second plurality of distribution branches, and the first plurality of distribution branches and the second plurality of distribution branches each receive reductant flow from their respective manifold in opposite directions. A method for injecting a reductant into an exhaust comprises generating a first mass flow gradient of reductant along a first axis, generating a second mass flow gradient of reductant along a second axis, wherein the mass flow gradients decrease in directions along their axes, wherein the first direction and the second direction are disposed in a counterflow arrangement.
