Abstract

A lance (27) is inserted inside a feeder nozzle (20) or pipe for recirculated flue gas belonging to a furnace. The front free end of the lance has a nozzle head (28) with adjustable spray angle. The feeder pipe (30) to the lance is used as a regulatable valve arrangement (29). It is used for opening and shutting the medium inflow, pressure and quantity and for adjusting opening periods and intervals between two opening phases with regulator (32).
