Combined regulating and cleaning device for the air opening in a firing kiln's air input channel

摘要

The invention concerns a combined regulating and cleaning device for achieving an effective adjustment and cleaning of the air input channel in a firing kiln. The said device consists of swivelling flaps around a shaft essentially at right angles to the longitudinal axis of a channel connected to the air input opening. The turning radius of these flaps determines the open inlet cross section of the input channel and which can be moved in the longitudinal direction of the shaft in maximum extended position to clean these walls.
