FUEL TECH, INC.

Fuel Tech, Inc. is a technology company focused on developing, commercializing, and applying proprietary technologies globally for air pollution control, process optimization, water treatment, and advanced engineering services. These technologies help customers operate efficiently, cost-effectively, and sustainably. The company's nitrogen oxide (NOx) reduction technologies include NOxOUT® and Advanced Selective Non-Catalytic Reduction (SNCR) systems, and ASCR® Advanced Selective Catalytic Reduction systems. SCR reagent supply systems feature the ULTRA® and U2A processes for safe ammonia generation and UDI™ Urea Direct Injection systems, alongside aqueous and anhydrous ammonia storage and delivery systems. Fuel Tech has installed these NOx reduction technologies on over 2,000 units worldwide. Fuel Tech's Air Pollution Control (APC) technologies include particulate control with Electrostatic Precipitator (ESP) products and services, with experience on units up to 700 MW. Flue Gas Conditioning (FGC) systems use sulfur trioxide (SO3) and ammonia-based conditioning agents to enhance ESP performance by altering fly ash particle properties. The company's particulate control technologies have been installed on more than 600 units worldwide. The company's FUEL CHEM technologies involve chemical injection programs that improve the efficiency, reliability, fuel flexibility, boiler heat rate, and environmental status of combustion units. These programs control issues such as slagging, fouling, corrosion, opacity, acid plume, and the formation of sulfur trioxide, ammonium bisulfate, particulate matter, sulfur dioxide, and carbon dioxide. Fuel Tech uses its proprietary TIFI® Targeted In-Furnace Injection™ processes to apply specialty chemical programs to units burning various fuels, including coal, heavy oil, biomass, and municipal waste. These TIFI® programs encompass design, modeling, equipment, reagent, and service to deliver customized on-site programs aimed at improving plant operations, providing a return on investment, and assisting with emission regulatory compliance.
