The patented infrasound cleaning system is a modern solution for the cleaning needs of the energy sector. It is ideally suited for boilers where maximum availability, reduced maintenance, and improved energy efficiency are desired — all while considering environmental impact and personnel safety.
TECHNICAL SOLUTION
- The infrasound cleaning system utilizes low-frequency sound waves (15–25 Hz) to clean heat transfer surfaces efficiently and continuously — without mechanical contact or production interruptions, within temperature ranges of approximately 550–130°C.
- Infrasound attenuates slowly, allowing one device to clean a distance of approximately 10–15 meters both upstream and downstream.
- Operating pressure is approximately 6 bar, and a separate pressure accumulator is required.
KEY BENEFITS
- Improved heat transfer – better efficiency and reduced energy consumption
- Fewer operational shutdowns – continuous cleaning without outages
- Reduced need for water washing – lower water consumption and maintenance
- Better working conditions and reduced personnel strain – safer work environment
- Lower CO₂ emissions per unit of energy produced
- Enables use of lower-cost fuel fractions – flexibility and cost-efficiency
- 10°C lower flue gas exit temperature can result in up to 0.5% fuel saving
OPERATION AND MAINTENANCE
- Easy to maintain. User maintenance is recommended every 3 months – no boiler shutdown required.
