Reduction of heat transfer tube inner surface or evaporating the inner surface of the tube meat status monitoring device

摘要

PROBLEM TO BE SOLVED: To provide a device for monitoring the thickness reduction of the inner surface in a heat transfer pipe or the inner surface in an evaporation pipe, capable of understanding a change acquisition of a surface position relevant to thickness reduction by abrasion due to circulating cooling water.;SOLUTION: The device 10 for monitoring the thickness reduction of the inner surface in a heat transfer pipe or the inner surface in an evaporation pipe is a monitoring device for monitoring the thickness reduction of a heat transfer pipe or an evaporation pipe. The device includes: a movement means 12 that moves along a fin tube 11 of the inner surface in the heat transfer pipe or the inner surface in the evaporation pipe; a laser measurement means 13 that is disposed in the moving means 12 and measures the thickness reduction on surfaces of the heat transfer pipe or the evaporation pipe with a laser; a cable means 14 that includes a light-guide path for guiding a laser beam to the laser measurement means 13 and a lead-out path for transmitting reflected light; and a thickness reduction determination device that compares a data of the laser measurement to a past data or a standard data to determine the current thickness reduction.;COPYRIGHT: (C)2012,JPO&INPIT
