Boiler bank surface temperature profiler
First Claim
1. A system for determining build-up on a plurality of tubes of a boiler, the system comprising:
- extending means for being movably extendable into the boiler near the tubes and for removing build-up from the tubes;
optical fiber means for taking a separate temperature reading at a plurality of positions along a length of the extending means; and
means for determining build-up on the tubes, based on the separate temperature readings taken from the length of the extending means.

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.
