Waste Heat Recovery Systems for Steam Boilers

In a steam boiler the heat from the flue gas is transferred to the water, which then turns into steam. Downstream of the boiler the flue gases are still high in temperature and are typically 50ºC or more above the steam temperature. Flue gas heat exchangers downstream the boiler can recover this waste heat and improve the boiler fuel efficiency.

Finding the Root Cause of Boiler Tube Failures

Causes: Tube damage occurs due to the combination of thermal fatigue and corrosion. Corrosion fatigue is influenced by boiler design, water chemistry, boiler water oxygen content, and boiler operation. A combination of these effects leads to the breakdown of the protective magnetite on the ID surface of the boiler tube.
