Abstract
A system for determining the cleanliness of a boiler having a plurality of tube banks by obtaining a temperature profile of the boiler heat transfer surfaces includes extending an extension arm, such as a soot blower lance, near the tube banks of the boiler. A separate temperature reading is taken at intervals along the length of the extension arm by utilizing either a plurality of infrared non-contact temperature sensors or a plurality of optical fibers. Each separate temperature reading enables a temperature profile to be determined along the length of the extension arm which, in turn, allows deposit accumulation on the tube banks to be determined.
