Rapping System

A rapping device system is a special product for cleaning horizontal superheater paths, especially for waste, biomass and industrial plants.

Rapping device systems can be applied to remove deposits from the heating and reaction surfaces without any additional cleaning medium like steam, air or water.

Clyde Bergemann develops and produces pneumatic single rapper, SMART Rapping, in cooperation with Norgren company and offers pneumatic and mechanical rapping Systems.

Principle of cleaning

By rapping the polluted heating tube bundles caused an oscillation, which shake off the build up material. Cleaning with air or water is no longer required and takes place by means of mechanical hammers or by pneumatically driven impact cylinders. For heavy fouling pneumatic rapping systems are recommended which enable higher impact energies and, as a result, a still better cleaning effect.

Sections of extraordinary difficult accessibility can be reached with the help of individual rappers.

SMART Rapping - Pneumatic single rapper: 

Individually adjustable impact energy permits target optimisation of the heating surface cleaning procedure to ensure the overall efficiency of the evaporators, superheaters and economisers are kept consistently high.

  • Noise protection of the rapping system is possible (optional)
  • If the boiler is a positive pressurised unit, sealing air prevents the admission of flue gases
  • Wear indicator on cylinders to provide constant check to operating staff
  • Individually adjustable impact energy for optimised cleaning
Your Benefits:
  • Optimal cleaning of the plant – extends the boilers operational time
  • No air or steam is supplied as blowing medium – results in lower maintenance expenses, less spare parts and reduced operating costs
  • Comfortable operation and feedback to the control room
  • Overall increase of efficiency of the evaporators, superheaters and economisers
  • Extended boiler availability
  • Maximises thermal efficiency and reduced gas exit temperatures
