Fuel Tech Announces Demonstration of TCI™ Targeted Corrosion Inhibition™ Technology

Business Wire, June 8, 2007

BATAVIA, Ill. -- Fuel Tech, Inc. (Nasdaq: FTEK), a world leader in advanced engineering solutions for the optimization of combustion systems in utility and industrial applications, today announced its first commercial order for TCI[TM] Targeted Corrosion Inhibition[TM] technology. This demonstration, to be conducted on a waste-to-energy (WTE) boiler owned by Maine Energy Recovery Company (MERC), is designed to inhibit chloride-induced corrosion on high-temperature surfaces, caused by the combustion of plastics and other materials contained in refuse derived fuel.

The goal of the TCI demonstration program is to reduce corrosion rates by at least 50%, comparable to results previously achieved on this same boiler in shorter run tests. Of particular interest will be the technology's ability to ameliorate the impact of highly corrosive flue gases generated in MERC's boiler, which have resulted in superheater tube failures and unplanned shutdowns. Fuel Tech will continue to treat this unit for slag mitigation using its well established TIFI[TM] Targeted In-Furnace Injection[TM] technology.

John F. Norris Jr., President and Chief Executive Officer, commented, "With corrosion control representing a major challenge for most WTE boiler operators, we welcome the opportunity to deploy our TCI technology with MERC, one of our longest-standing FUEL CHEM([R]) customers. Fuel Tech continues to explore other commercial opportunities for its TCI programs in the WTE market, both in the United States and abroad."
