As flue gas cools, sulfur compounds within the gas begin to condense into highly corrosive acidic liquids. Once the gas temperature falls below the acid dew point, heat transfer surfaces become exposed to acidic condensate.
Lower Temperature
Higher Condensation Risk
More Corrosion
Reduced Equipment Life
Corrosion reduces component life.
Frequent repairs and replacement.
Reduced operational availability.
Higher exhaust temperature cannot be reduced to avoid corrosion.
By protecting heat transfer surfaces from acidic condensate, facilities can safely recover additional thermal energy from low-temperature flue gas streams:
Deep Heat Recovery
Condensation Recovery
Combuation Optimization
Industrial Heating
