Remaining life assessment of radiant super heater in creep regime

Assessment of remaining life of power plant components is necessary for awareness of its health. This is beneficial in preventing failure and force shutdown while life is expended. It also helps to avoid to capital investment on premature
replacement of tubes. This study investigates the condition of platen superheater of pulverized fuel fired boiler. Visual inspection and various testing like dye penetrant testing, magnetic particle testing and ultrasonic testing carried out for checking structural integrity of header and tubes. Metallographic replication carried out for both inlet and outlet header of platen superheater. Oxide-scale measurement carried out for superheater tubes and remaining life of tubes calculated.
