The arrangement is for cleaning and controlling airflow and where appropriate pushing away melt in an air channel of recovery boilers within the paper and pulp industry. By inclining the regulating device 10 at an angle to the horizontal plane and at the same time making the piston of the regulating device run in contact with the side and upper walls 24a, 24b and, respectively, 22 of the air channel, optimum airflow control and a more compact installation can be achieved. The airflow can be adjusted more rapidly with a small regulating movement at the same time as very good penetration of the air into the furnace 4 is achieved.
