Through methods

such as chemical composition analysis

macroscopic examination

and microstructure analysis etc.

the causes resulting in tube-burst on platen superheater in Shijiazhuang Thermal Power Co Ltd have been analysed

the equivalent temperature being estimated through thickness of the oxide skin

and residual service life being calculated. It is recommended to strengthen the plant-incoming inspection of high-temperature metallic parts

on-line monitoring

and service life evaluation etc.

so as to ensure safe operation of the unit.
