Abstract
An overfire air injector for use in a fossil fuel-fired combustion device includes a cylindrical nozzle having an outlet end formed with a step diffuser comprising one or more radial steps that enlarge the outlet end of the nozzle. An atomizer lance may be mounted within the nozzle, having a discharge orifice at the outlet end of the nozzle, for supplying a reducing agent to the overfire air to reduce NOx emissions.
