N2 - The article briefly describes some of the characteristics of oxide growth and exfoliation, the impact of these oxides in modern power plants, and highlights findings from the workshop and requirements for additional research. Superheaters (SH) and reheaters (RH) in modern supercritical (SC) and ultrasupercritical (USC) coal-fired steam power plants operate with maximum steam temperatures between 580 and 620°C and pressures up to 28 MPa. The inner layer of the essentially double- layer scale formed on TP347H has a very irregular thickness, and while separation also occurs between the two main layers, the outer layer exfoliates completely. To minimize the likelihood of tube failures, manage exfoliation, and select suitable materials for different operating conditions, EPRI conducted modeling work on the process of oxide growth and exfoliation taking into consideration the accumulation of strain in the oxide or oxide layers.
