RETRACTABLE
SOOTBLOWER Model SLR-3 |
Description:
The
soot blower comprises fixed and moving components. The movable head supporting
the lance travels on a fixed guide-support. The lance is a retractable,
telescopic type provided with two end nozzles.
On the front, fixed part of the soot blower, are the electric motor, with
its reduction gear, flanged steam inlet, with relevant counter-flange,
the blower steam valve, and the hand-wheel for emergency operation. Between
the flange of the blower steam valve and the counter-flange could be inserted
a calibrated diaphragm to reduce pressure steam in the lance of the soot
blower.
The blower is also equipped with a wall support, as shown on the enclosed
drawing, limit switches, and supporting lugs.
This
type of soot blower results:
• easy to install;
• simple to maintain;
• safe and reliable.

Operating
sequence The
electric motor, through a reduction gearbox, induces translation
and rotary motion in the lance. The lance is mounted in a travelling
carriage assembly which is driven by a screw with translation generated
directly through nut screw and rotary motion generated through the
carriage gearbox. When the lance advances sufficiently for the nozzle
to entrance in the boiler cavity, the supply valve is opened automatically
and blowing starts. 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is fully withdrawn another limit switch signals the end of the cycle.
