The position of the sootblower nozzle with respect to the leading edge of the boiler bank has been known to have a great effect on the ability of the jet to exert force on deposits that are sitting on the bank [1]. Smart Sootblower has been developed to increase the cleaning performance of the jet by positioning the nozzles such that as to minimize the jet interaction with the boiler tubes. It is equipped with dual motors that independently control the transversing and rotating motion of the lance. Unlike conventional sootblowers, it cleans the boiler heat exchanger tube surfaces with full knowledge on where the sootblower nozzles are positioned with respect to the boiler banks and full control on the helix movement of the lance. Current advancement in fouling measurement system has enabled us to locate the area where the deposit is accumulating. With the help of these detection systems, Smart Sootblower can be used to target and adjust cleaning intensity based on fouling condition, thus maximizing sootblowing effectiveness, minimizing sootblower steam consumption and preventing sootblower induced tube erosion.
