EROSION AND HIGH-TEMPERATURE CORROSION MONITORING APPARATUS USING THE BIMETAL

摘要

The present invention relates to an apparatus for monitoring erosion and high temperature corrosion using bimetal, and more particularly, to measure corrosion and erosion in a tube such as a heat exchanger or a boiler in an economical manner, using a bimetal for determining a replacement cycle of a tube. Erosion and high temperature corrosion monitoring apparatus. The configuration of the present invention is a tube portion provided in the heat exchanger or boiler; A specimen portion attached to the inner side or the outer side of the tube part in a cantilever shape and having a pair of metals of different materials joined to each other; And a detection unit provided at one end of the specimen to detect the degree of corrosion of the tube, wherein the detection unit detects contact with the specimen through a current to detect the degree of erosion and corrosion of the tube. It provides an erosion and high temperature corrosion monitoring apparatus using bimetal.
