This patent describes a process for reducing nitrogen oxides in combustion emission systems. It comprises mixing a reburning fuel with combustion emissions in a gaseous reburning zone such that the reburning zone is substantially oxygen deficient; passing the resulting mixture of reburning fuel and combustion emissions into a first burnout zone; introducing a first stream of burnout air into the first burnout zone; advancing the resulting mixture from the first burnout zone to a second burnout zone; and introducing a second stream of burnout air into the second burnout zone.
