An intelligent sootblower that may be configured as a modification to an existing sootblower or a specially constructed sootblower that, in addition to its normal soot blowing functions, has the capability to measure the flue gas, lance tube, and/or cleaning fluid temperatures. One or more thermocouples or other temperature measuring devices are carried by the sootblower lance tube that is inserted into the boiler. This allows for the temperature of the flue gas, lance tube, and cleaning fluid to be measured as the sootblower lance tube is inserted into and retracted from the boiler. Multiple temperature measuring devices may be located on the sootblower lance to measure the temperature across heat transfer surfaces and at different locations along the lance tube. A data transfer device transmits the temperature measurements from the rotating thermocouple to a non-rotating data acquisition unit for use in boiler cleaning and other operations.
