STEAM-PIPE TEMPERATURE MEASUREMENT DEVICE, STEAM-PIPE TEMPERATURE MEASUREMENT METHOD

摘要

A steam-pipe temperature measurement device according to the present invention includes: an optical fiber for measuring the temperature of the surface of a steam pipe inside which steam obtained through heat exchange between water to be supplied to a boiler and a combustion gas circulates; and a cover that is mounted so as to surround the steam pipe, with the optical fiber sandwiched therebetween, such that the optical fiber is brought into close contact with the steam pipe along the longitudinal direction of the steam pipe.
