Function: 

• The Jetblower combines the advantages of a long retractable sootblower with those of a twin lance blower. 
• When the sootblower is not in operation, the lance tube with nozzle head is withdrawn from the flue gas pass into a safe position. 
• The blowing agents of air, steam or water are admitted to the lance tube with nozzle head through two separate valves via an inside tube and a flexible line.
• Inside the lance tube the two blowing agents are fed on separate routes to the nozzle stem assemblies.
• Because of this sophisticated design no rakes are necessary.

Special features:

• Three cleaning methods: 
• High-pressure water cleaning with full jet nozzles 
• Blowing with steam or air through venturi nozzles 
• Low-pressure water cleaning 
• Blowing mode and movement are controlled separately. 
• At air heaters with rotating rotor the rotary speed control or Go-Stop-Go operating mode can be applied.
• Constant running speed for homogeneous cleaning is possible in other application areas.
• Limit switches control the travel between rest position and return position
