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.
