Function:

• The electric motor induces lateral and rotary motion in the lance through a reduction gearbox.
• The lance is mounted in a travelling carriage assembly which is driven by chain, with lateral motion generated directly through sprockets and rotary motion generated through the carriage gearbox.
• When the lance advances sufficiently for the nozzles to clear the wallbox, the supply valve is opened automatically and sootblowing commences. 
• At the furthest extent of travel, the carriage trips a limit switch which reverses the mechanism. 
• When the lance is fully withdrawn, another limit switch signals the end of the cycle.

Special features:

• Heavy duty chain drive mechanism which is extremely reliable.
• Convergent-divergent nozzle design.
• Simple maintenance.
• Emergency manual operation using crank handle.
• Also available in a partially retracting configuration.
• Custom design options - motor and gearbox assembly can be located inboard or outboard on either side of the sootblower to accommodate site requirements.

Options:

• External settling of throttle disc
• Electrical components ATEX certified for "Ex" hazardous area installation
• Special wallbox designs for negative pressure or positive pressure
• Sealing and scavenging air for lateral duct compressor
