Main field of application Cleaning of heat exchangers with heavy fouling and flue gas temperatures up to 1,500 °C
Travels
Principle of cleaning
The lance tube with two opposite high-performance nozzles is helically moved into the flue gas pass.
The blowing process begins as soon as the two nozzles have passed through the boiler wall.
During the blowing process the lance tube continues to move helically into the flue gas pass.
On reaching the front-side end position the direction of movement changes and the lance tube returns to its starting position.
Special features
integrated stop valve with adjustable throttle disc for comfortable adjustment of the blowing pressure
temperature-resistant lance tube material
high-performance nozzles
stainless feed tube material
travel monitoring by limit switch
integrated gear motor for advance and rotating movement
multi-blowing pattern for more uniform and complete cleaning with minimum heating surface loading which is standard for RK-SL and RL-SL, and an option for all other long retractable sootblowers.
two-rack drive design for minimum stress and high stability available for long travels.
