Retractable Sootblower – SMART RSG
Retractable Sootblower (SMART RSG)

Operating Principle

  • The lance tube with high-performance nozzles is moved into the flue-gas path as per a desired blowing pattern
  • The unique dual-motor design allows independent and variable traversing and rotational speeds of the lance tube for targeted cleaning
  • The accurate positioning of the lance tube is carried out by these gear motors with a high-resolution position sensor
  • Oscillating operation without axial movement enables a higher cleaning effect without increasing steam consumption at the same time

Technical Summary

Clyde Bergemann has several types of retractable sootblowers available for cleaning heat exchangers – all designed to deliver optimum results within the strict requirements of the individual industries to ensure trouble-free operation.

The SMART RSG is the most advanced and flexible on-load cleaning system for best cleaning results in the convection area of the boiler, with a unique dual-motor design which allows independent and variable traversing and rotational speeds. These speeds can be varied at any time for targeting cleaning.

  • Cleaning Medium: Steam, Air
  • General Application Areas: Superheater, Reheater
  • Travel Range: 0.5 m – 14 m
  • Cleaning Arc: Flexible
  • Key Industries: Power Generation, Waste-to-Energy, Biomass, Other Industrial Processes

Key Features

  • Poppet valve with externally adjustable throttle disc for easy setting of the blowing pressure
  • Stainless-steel feed tube, polished to minimise leakage at stuffing box connection with lance tube assembly
  • Creep-resistant lance tube with high performance nozzles to withstand high temperature applications
  • Double-rack design for higher stability
  • The “Go-Stop-Go“ mode enables intensive cleaning by continued rotation in places with severe deposits
  • Flexibility of cleaning parameters such as axial speed, rotational speed, blowing pressure and blowing angle to enable targeted cleaning
  • Travel monitoring by two limit switches; third limit switch for monitoring and controlling the rotation reference point
  • Wall box with sealing elements corresponding to boiler pressure mode
  • Sealing and scavenging air piping with dedicated fan (optional)
  • Add-ons: SMART Set for external adjustment of throttle disc / Self-adjusting stuffing box packing
