FUEL CHEM^® TCI™ Targeted Corrosion Inhibition™ Technology            (brochure)

Fuel Tech has announced the availability of a high-temperature slag/corrosion control technology designed principally for boilers in the waste-to-energy (WTE) industry. This new technology builds upon the Company’s established TIFI™ Targeted In-Furnace Injection™ program, designed to inhibit slag build-up in a variety of solid- and liquid-fueled boilers.

Marketed as the TCI™ Targeted Corrosion Inhibition™ program, this technology represents a unique chemical solution to chloride-induced corrosion of high-temperature surfaces, arising from the burning of plastics and other materials contained in municipal solid waste or refuse derived fuel (RDF). As the waste fuel is combusted, highly corrosive flue gases are generated in the WTE boiler, often resulting in tube failures and unplanned shutdowns. Depending upon the severity of tube corrosion, this condition may necessitate more frequent replacement of superheater pendant tube sections or the use of costly, higher alloyed materials, either to shield metal surfaces or serve as replacement tube material.

Tests conducted at commercial WTE units burning RDF demonstrated a reduction in corrosion rates in excess of 50%, coupled with a simultaneous improvement in slag control. Other potential applications for TCI technology include biomass and industrial boilers.
