Latest Patents

Stevens holds a patent for an "Indexing Sootblower." This invention features a long retracting sootblower designed for boiler cleaning. The sootblower includes a lance tube that advances into and out of a boiler while simultaneously rotating. It is equipped with one or more nozzles that discharge a jet of blowing medium, tracing helical paths. The indexing mechanism allows for the repositioning of these helical paths between actuation cycles. This minimizes boiler erosion and mechanical stress caused by repeated impacts of the blowing medium against boiler surfaces. The mechanism includes slidable longitudinal advancement rack sections that enable the engaging pinion gears to index by one or more teeth with each actuation cycle. A movable rack portion is biased by a compliant element to maintain its normal position until the lance carriage is initially advanced, causing the movable portion to index with respect to the fixed portion of the rack. This innovative design ensures that the movable rack portion returns to its normal position during other periods of the actuation cycle, providing effective indexing.
