Function: 

• The electric motor, through a reduction gearbox, induces lateral motion in the lance which is mounted in a chain driven travelling carriage assembly
• When the sootblower is actuated the lance moves forward to its full extent and at the furthest extent a limit switch is tripped which reverses the mechanism.
• Sootblowing is carried out on the reverse stroke in timed steps (the blower nozzle position is controlled using an encoder and PLC control panel).
• When sootblowing is completed, a second limit switch signals the end of the cycle. 
• Alternatively, the blower can be designed to blow during the forward stroke with automatic reversal when the lance tubes are fully extended.
• Optional fans can be fitted to the high pressure lance to supply air sealing to the HP nozzles when not in use.

Special features: 

• integrated stop valve with adjustable throttle disc for straightforward adjustment of the blowing pressure 
• temperature-resistant blowing lance material 
• high-performance nozzles 
• stainless feed tube material 
• travel distance controlled by limit switch 
• nozzle positioning controlled by encoder
• reduction motor gearbox for advance movement

Options:

• pressure transducer with adjustable set point
• internal lance purge via scavenge valve 
• special wall box designs for negative pressure, positive pressure and sound protection 
• fully connected sealing and scavenging air
