The pneumatic rapping gear type pKL is an automatically operating online cleaning system. It cleans the heating surfaces of a boiler by rapping against specially formed rams. It is mainly used in case of horizontal boiler passes with suspended economizers.

The boiler walls are provided with equispaced rams resting against the bottom of the headers of the tube banks. One or several rapping carriages are moved from ram to ram. Depending on the arrangement they are equipped with one or two superposed impact cylinders.

These pneumatic special Rosink impact cylinders are applied to rap on the reinforced back of horizontally arranged headers. The impact energy applied causes the vertically suspended heating surfaces to vibrate in order to remove the deposits.

Especially when there are numerous rapping points the cleaning by means of a rapping carriage is the more efficient and economical solution!

Rosink Rapping Systems stand out due to a rugged design, little maintenance requirements as well as a low need to store spare parts.
