Mechanical or pneumatic rapping systems

Whether it’s a mechanical rapping system, a carriage with pneumatic cylinders, or individual rapping cylinders: the right system for every application!

The System:

In horizontal boiler circuits in waste incineration plants and biomass power plants, the evaporators, superheaters, and economizers are optimally cleaned by so-called rapping devices.

In this process, pneumatic or mechanical rapping occurs on the floors of the horizontal collectors, providing an impulse to the vertically hanging heating surfaces, loosening the dirt from the pipes. And all this without the use of additional cleaning media such as steam, air, or water!

With our over 20 years of experience in optimizing existing rapping systems, we have been offering various proprietary rapping devices for 10 years.

Each system has its advantages and is individually adapted to the respective boiler and fuel, completely manufactured by us in Salzgitter, “Made in Germany”.

Pneumatic rapping device with individual knockers EKL

Each collector is knocked by its own impact cylinder, which can be individually controlled.

Pneumatic rapping device with rapping carriage PKL

One or two impact cylinders are mounted on an electrically driven rapping carriage, thus cleaning a complete area of the boiler’s horizontal circuit.

Mechanical rapping device MKL

A complete area of the boiler’s horizontal circuit is cleaned by several drop hammers arranged on a common rotating shaft. The shafts are each electrically driven. The impact energy depends on the weight of each individual drop hammer.

We are happy to advise you on selecting the right rapping system for your boiler system and your contamination problem.

Advantages of our rapping systems::

• Robust and durable design

• Optimized ram guide prevents the rams from jamming

• Maximum conversion of impact energy into impulse on the heating surface
