Chapter 14 - Boiler System Failures | SU

2019-10-9 · The application of a fast-acting oxygen scavenger, such as catalyzed sodium sulfite, also helps protect this vital part of the boiler. While oxygen pitting is the most common form of waterside corrosion that causes economizer tube failures, caustic soda has occasionally accumulated under deposits and caused caustic gouging.

Boiler Combustion | CleanBoiler.o

One technology that offsets the efficiency loss due to lower flame temperatures in a firetube boiler is flue gas recirculation. Although the loss of radiant heat transfer could result in an efficiency loss, the recirculated flue gases increase the mass flow through the boiler – thus the convective heat transfer in the tube passes increases.

applied to small boilers [7]. However, it is quite diffi-culty to apply the oxygen enriched combustion technol-ogy to large-scale utility boilers at present, which is due to the less theory and related experiment. In addition, the understanding of internal temperature, pressure, pollutant emissions in boiler
