Abstract
A retractable sootblower for use in cleaning heat exchanger surfaces during a single stroke of its operating cycle. A control system is utilized to vary the rate at which the blowing medium is discharged from the lance tube into the heat exchanger. The rate of discharge is greater during the cleaning stroke of the lance tube than during the non-cleaning stroke.
