Retractable Sootblower (VX-H)
Operating Principle
- The lance tube with high-performance nozzles is helically moved into the flue-gas path
- The blowing process begins shortly after the nozzles have passed through the boiler wall
- On reaching the prescribed travel, the direction of movement changes and the lance tube returns to its rest position
