Effect of High Temperature on Rear Pass Boiler Tube

2017-12-1 · This work presents the investigations on three sample boiler tubes in the rear pass area (low temperature reheater 1 (LTR1)(A210-A1), intermediate temperature superheater (ITS)(A210-C) and economizer tubes) ) (A210-C) of a coal-fired power plant in Malaysia, which had been replaced during major overhaul in January 2014 after running for about 11 years.
