Zusammenfassung:Common cycling-dominated power plant failures occur mainly in the HRSG tubing and the HRSG casing. Superheater and reheater sections mainly suffer from thermal quenching transients due to water in headers from improperly sized/designed drains and from improperly operated/maintained attemperator spray systems that generally result in tube-to-header failures, as shown in Figure 2. Evaporator tube failures occur due to overheating and excessive deposition of iron and other chemical deposits.
