Function:

• 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
• sturdy sootblower design (drive through two racks)

Options:

• external setting of throttle disc
• droop correction for defined guidance of nozzle head near the optimum sootblower centre line
• multi-blowing pattern for more uniform and complete cleaning with minimum heating surface loading
• special wall box designs for negative pressure, positive pressure or sound protection
• sealing and scavenging air with lateral duct compressor
