ABSTRACT:
An emissivity probe for measuring reflected energy from interior wall surfaces of large scale boilers. The emissivity probe uses a pair of light guides which respectively receive light energy from the interior of the boiler and that reflected off a wall surface. Using appropriate photo detectors sensitive to a desired light wavelength range, a ratio of the reflected and incident radiation is provided. This provides a measure of the reflectivity of the wall surface. The reflectivity values are used to control boiler cleaning systems.
