Fuel Tech, Inc. provides engineered solutions for the optimization of combustion systems in utility and industrial applications worldwide. The company offers air pollution control technologies, such as low and ultra low nitrogen oxide (NOx) burners, over-fire air systems, NOxOUT and HERT selective non-catalytic reduction systems, and advanced selective catalytic reduction systems to reduce NOx emissions in flue gas from boilers, incinerators, furnaces, and other stationary combustion sources. It also provides ULTRA technology, which converts urea-to-ammonia on site offering safe reagent for use in selective catalytic reduction systems; and flue gas conditioning systems that are chemical injection systems used to enhance electrostatic precipitator and fabric filter performance in controlling particulate emissions. In addition, the company offers FUEL CHEM technologies, which control slagging, fouling, corrosion, opacity, and other sulfur trioxide-related issues in furnaces and boilers through the addition of chemicals into the furnace using Targeted In-Furnace Injection technology. Fuel Tech, Inc. offers its FUEL CHEM program for plants operating in the electric utility, industrial, pulp and paper, waste-to-energy, university, and district heating markets, as well as to the owners of boilers, furnaces, and other combustion units.
