The soot blower mainly consists of:
• main body, properly said, with flanged connection to the wall support;
• wall box, positive or negative pressure types are available;
• automatic steam valve for steam inlet with flange and relevant counter flange;
• head with flanged connection for admitting steam;
• air check valve with a threaded ¾” connection on the rear head;
• tube lance connection.
• lance with multi-nozzles (single of double row).

This type of soot blower results:

• compact and easy to install;
• simple to maintain;
• safe and reliable.

Rotating sootblower installed on one exhaust gas boiler
on board of M/V Sun Princess


This type of sootblower is used in confined spaces, usually at a gas temperature lower than 600-700°C

Installation type
• Convection bank
• Economiser
• Waste heat recovery boiler

Technical data Operating sequence

When the blower is started from the rest position the electric motor rotates the lance through the reduction gear and the drive gear. This movement opens the valve by means of a cam. The lance rotates until the design blowing arc is completed. The valve is closed by reversing mechanism back to its rest position. The rotation of the lance continues up to get its rest position.
