Part-Retractable Axial Sootblower (VX-AB)
Part-Retractable Axial Sootblower (VX-AB)

Operating Principle

  • The blowing tube is equipped with high-performance nozzles over the whole length and is supported in the flue-gas path
  • During the blowing process the blowing tube continues to move axially into the flue-gas path
  • On reaching the prescribed travel, the blowing tube returns to its rest position
  • The blowing tube remains partly in the flue-gas path

Technical Summary

Clyde Bergemann’s Part-Retractable Sootblowers are the solution for an efficient cleaning of heating surfaces in various applications, with heavy fouling and flue-gas temperatures < 800 °C (upper limit may vary based on type of application).

This type of sootblower is a cost-effective solution especially for medium sized boilers. This economic and easy to maintain sootblower is constructed for dependable operation, indoors and outdoors in all climates. It´s compact design is highly compatible with the space restrictions often found on fired heater installation. For this vast range of applications, Clyde Bergemann offers several part-retractable sootblower versions with different travel ranges to meet specific cleaning requirements. Also suited for hazardous area conditions.
