Rotating Element Sootblower DB
Operating Principle
- The blowing tube is equipped with high-performance nozzles over the whole length and rotates in the flue-gas path
- During the blowing process, the blowing tube performs a prescribed number of rotations
- A cam-controlled valve opening enables cleaning of specific segments
- The blowing process ends when the prescribed number of rotations have been performed
- Blowing tube remains in flue-gas path
Technical Summary
The DB Rotating Element Sootblower is designed to clean convection surfaces, as well as heat exchangers with light fouling and flue-gas temperatures < 500 °C. The blowing element always remains in the boiler, supported by element bearings usually attached to the boiler tubes. Specially designed nozzles are located on the element for each specific installation. Also suited for hazardous area conditions.
