Driver Impact Analysis

RESTRAINT

"Corrosion, fouling, and demanding maintenance requirements in aggressive flue gas environments."

Corrosion remains one of the most important restraints affecting incinerator heat exchanger reliability. Waste combustion produces flue gases containing chlorides, sulfur compounds, particulates, acidic substances, and other contaminants capable of degrading exchanger surfaces. Approximately 35% of unplanned thermal recovery shutdowns are associated with fouling or corrosion-related problems.
