Rotating Element Sootblower

The Rotating Element Sootblower DB is designed to clean convection surfaces as well as heat exchangers with slight fouling and flue gas temperatures < 932° F.

The blowing element of this type sootblower remains in the boiler at all times, supported by element bearings usually attached to the boiler tubes.

Specially designed nozzles are located on the element (as required) for each specific installation. Saturated or superheated steam, as well as compressed air, may be used as the blowing medium.

Principle of cleaning
  • The blowing tube is equipped with nozzles over the whole length and rotates in the flue gas path 
  • During the blowing process the blowing tube performs a rotational movement
  • A special control of the valve also enables cleaning of specific segments
  • The blowing process ends when the necessary number of rotations have been performed
  • Blowing tube remains in flue gas path
Features
  • Temperature resistant blowing tube material, high performance nozzle and stainless feed tube material
  • Compact track beam for restricted spaces encloses all moving parts for personnel protection
  • Integrated sootblower valve with adjustable throttle disc for adjustment of blowing pressure
  • Tailored to suit the site/regional specific hazardous area conditions including: ATEX, CENELEC, IEC, NEC, GOST, CCOE, and NEPA
  • Cantilever support design eliminates need for rear support requirements
Benefits
  • The DB product is the global industry standard tested and proven in the most severe operating conditions around the world
  • The blower can be configured to provide a blowing arc of between 30 and 360°. Typically, the blower is rotated one to six times per operational cycle
  • Extended boiler availability and increased boiler efficiency
  • Checks deposit build-up 
  • Prevents fouling and blockages in the superheater, economizer and air heater
  • Maximizes thermal efficiency and reduces gas exit temperatures
  • Reliable and simple to maintain
  • Design optimizes cleaning effect and minimizes consumption of steam, water and air
