Abstract
A sootblower assembly for cleaning heated surfaces within a boiler or other combustion system of the long retracting oscillation type. A kinematic drive mechanism is provided for causing the sootblower lance tube to oscillate such that cleaning medium discharge from nozzles on the lance tube emit jets of clean medium against the surfaces to be cleaned. The kinematics of the oscillation drive mechanisms are related to the lance tube nozzle positions and the distance to the surfaces being cleaned in various positions to provide a constant or nearly constant rate of sootblowing medium jet progression along the surfaces to be cleaned.
