Lifetime estimation of superheater header

Procedia Structural Integrity, 2016
AbstractThe safe operation of thermal power plants (TPPs) is largely determined by the reliability of main components of steam systems of power units, to which belong the headers of boiler superheaters.The aim of the study is to estimate the residual lifetime of superheater header starting from the initial defect size and up to the maximum allowable ...
