Rapping Systems

The rapping systems of Rosink-Werkstätten are mainly used in waste incinerators with horizontal boiler flues. Suspended evaporators, superheaters and economizers are cleaned by means of rapping.

Pneumatic cylinders or mechanical hammers 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.

Pneumatic Rapping Systems pKL

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

 

Mechanical Rapping Systems mKL

The mechanical rapping system type Rosink-Werkstätten-mKL 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 for horizontal boiler passes with suspended evaporators, superheaters and economizers.

The boiler walls are provided with equispaced rams resting against the header bottom of the tube banks. All rams of a boiler side are equipped with this mechanical rapping gear components, each ram has his own mechanical hammer. All rams need to be in a line.

The impact energy applied by the mechanical hammer causes the vertically suspended heating surfaces to vibrate in order to remove the deposits. The impact energy depend on the weight of the mechanical hammer and will be designed project-specific, for example 6-14 kg per each.

Rosink-Werkstätten Single Rapping System SRS

The pneumatic Rosink-Werkstätten rapping system SRS using single rapping cylinders is an automatically operating online cleaning system installed to increase the continuous operating time of boilers.

The boiler walls are provided with equispaced rams resting against the bottom of the headers of the tube banks. Each ram is provided with a compact Rosink-Werkstätten SRS single rapping cylinder used 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.
