Degradation of Heat Resistant Steel Tubes used for Superheater and Reheater in Thermal Power Plant Boilers

초록

Heat resistant steel tubes used for superheater and reheater in #3 Dangjin drove more than 10 years and #5 Ulsan drove more than 30 yaers were evaluated degradation through visual inspection, dimensional inspection, hardness test and metallographic examination. As a result of degradation evaluation, Degradation of heat resistant steel tubes with long-term operating hours and high temperature environment in #5 Ulsan was conducted quite a lot. Also degradation is influenced by high temperature and operation period. We can observe degradation condition of tubes through the hardness test and the metallographic examination.
