Failure analysis of high temperature superheater tube

Failure analysis of high temperature superheater tube (HTS) of a pulverized coal-fired power station Boiler or steam generator plays a vital role in power plant for electricity generations. In a high capacity power plant, the flue gas at the boiler outlet and a flue gas desulphurization (FGD) plant, scrubs the flue gas
