According to the invention, on the roof (10) of a waste heat boiler connected to a smelting furnace (16), there is placed a nozzle (11), wherethrough some oxygen-bearing gas is conducted into the radiation chamber (13) of the waste heat boiler, which gas brings about a change in the composition of the exhaust gases and simultaneously reduces the accumulation of dust accretions.
