SMART Rapping System
Operating Principle
- Rapping the fouled heat exchanger tube bundles with pneumatic cylinders induces oscillations, which shakes off the build-up deposit
- Individually adjustable impact energy allows targeted optimisation of the heating surface cleaning procedure, ensuring that the overall efficiency of the evaporators, superheaters and economisers are kept consistently high
Technical Summary
A rapping device system is a special product for cleaning horizontal passes, especially for waste-to-energy plants and other industrial applications. Rapping device systems can be applied to remove deposits from the heating surfaces without any additional cleaning medium like steam, air or water.
- General Application Areas: Superheater, Reheater, Economiser
- Key Industries: Waste-to-Energy, Other Industrial Processes
Key Features
- Pneumatically operated independent impact cylinders
- Impact Energy: Cylinders with 120 J, 150 J and 200 J output
- Highly flexible & optimised cleaning by individually adjusting impact energy and frequency of ramming based on the fouling degree
- Integrated force compensation
- Low noise level
- Low air consumption for activation of single rappers
- Sealing air to prevent the admission of flue-gases in case of positive pressure mode
- Optical operating pressure indicator (optional)
- Wear indicator on cylinders to provide constant check to operating staff
- Profibus connection to process control system (optional)
Product Benefits
- Increased plant availability due to reliable cleaning, resulting in efficient plant operation
- Prevents fouling in convection areas of the boiler
- Increased boiler efficiency through improved heat transfer
- Reduced gas exit temperatures
- Compact design through direct mounting on rapping points, thus eliminating need for steel structure (as compared to conventional rapping systems)
- No air or steam needed as blowing medium
- Low maintenance expenses, less spare parts and reduced operating costs
- Comfortable operation and feedback to the control room
- Intelligent, flexible operation, in conjunction with SMART Clean Compact
