Multi-Media Sootblower

The PS-A Multi-Media Sootblower uses for cleaning of heat exchangers, DeNOx, air preheaters and gas-gas heaters with steam, air or high pressure water at flue gas temperatures < 800°C with dual lances. Many boiler operators firing heavy fouling fuels have trouble keeping super heater surfaces from forming sintered deposits. These often cannot be removed with regular retracts using steam or air as cleaning medium.

On the other hand the regular use of water lances is prohibitive because they too often cause unacceptable levels of tube damage. The PS-A Multi-Media Sootblower normally cleans with steam, however, if and when necessary allows the operator to perform a special cleaning cycle during which water is blended into the cleaning stream in controlled amounts to remove any slag build up. When using water the PS-A Multi-Media Sootblower is designed to keep the thermal impact on the boiler tubes at a minimum by controlling the amount of water that is being applied to the heating surfaces.

Principle of cleaning
  • Both the water and steam/air blowing elements are axially moved into the flue gas path
  • Depending on the air preheater / gas-gas heater design, the tube are either fully or partly retractable
  • On reaching the front-side end position the direction of movement changes and the lance tube returns to its rest position
Travel range
