An annular fluid distribution device (20) for distributing fluid into a gaseous flow (14), that includes: a first fluid distribution manifold (30) having a first fluid inlet and first fluid outlets (24), wherein the first fluid outlets inject a first fluid into the gaseous flow; and a second fluid distribution manifold (32), having a second fluid inlet and second fluid outlets (26), wherein the second fluid outlets inject a second fluid into the gaseous flow. The second fluid manifold is isolated from the first fluid distribution manifold, and the first fluid outlets and the second fluid outlets are disposed on a common fluid outlet plane (43).
