2010/2/9 · Over spraying in both superheater and reheater has adverse impact on the boiler performance. This results in forced outage of boiler due to superheater tube failures. Spraying in reheater is generally avoided while designing by adopting other methods to control the reheater outlet temperature. Spraying in reheater reduces the overall cycle efficiency of power generation.
