Technologies to enable clean efficient energy®

CHP nightFuel Tech is a leading technology company engaged in the worldwide development, commercialization and application of state-of-the-art proprietary technologies for air pollution control, process optimization, combustion efficiency, and advanced engineering services. These technologies enable customers to operate efficiently in a cost-effective and environmentally sustainable manner.

Fuel Tech operates as a fully integrated company with a capital projects business to leverage its Air Pollution Control (APC) technologies, and a Chemical Technologies business which builds upon its proprietary TIFI® Programs. Both segments rely heavily on the Company’s unique ability to inject chemicals in combustion units, in precise concentrations and locations, to achieve a desired outcome.

Air Pollution Control (APC)

The Company’s nitrogen oxide (NOX) reduction technologies include low NOx burners, burner upgrades and over-fire air systems. In addition post-combustion NOX control systems include: NOXOUT® and HERT SNCR systems, Rich Reagent Injection (RRI) systems, and ASCR Advanced SCR systems. These technologies can be combined as part of an I-NOX™ Integrated NOX Control system. Our ULTRA® ammonia generation process and XCAM systems to measure ammonia are technologies centered around SNCR and SCR applications. For particulate control, Electrostatic Precipitator (ESP) technologies are applied through rebuild and retrofits to maximize performance to achieve regulatory compliance. In addition, Flue Gas Conditioning (FGC) technology through the use of sulfur trioxide and ammonia injection systems modify fly ash properties for collection by ESPs. These technologies have established Fuel Tech as a leader in NOX reduction, with installations on over 1,000 units worldwide, where coal, fuel oil, natural gas, municipal waste, biomass, and other fuels are utilized.

Chemical Technologies

The Company’s TIFI® technology revolves around custom-designed applications of chemicals to improve the efficiency, reliability, fuel flexibility and environmental status of combustion units. These programs control slagging, fouling, corrosion, opacity and the formation of sulfur trioxide, ammonium bisulfate, particulate matter (PM2.5), as well as, carbon dioxide (CO2). This technology is applied to units where coal, heavy oil, biomass, and municipal waste are utilized. Our HClear™ programs target the reduction of HCl emissions.

Services & Capabilities

We also provide a range of services, which include boiler testing, combustion optimization, and selective catalytic reduction (SCR) management services, which includes ammonia injection grid design and tuning. In addition to flow corrective devices such as static mixers and our GSG™ Graduated Straightening Grid to help optimize flue gas distribution and mixing in both power plant and industrial applications.

Many of our application designs rely on our proprietary Company's exceptional Computational Fluid Dynamics (CFD) modeling capabilities, enhanced by our internally developed, high-end visualization software; this is in addition to our Physical (Experimental) Modeling of system designs. These capabilities, coupled with our innovative technologies and multi-disciplined team approach, enable us to provide practical solutions to our customers’ most challenging problems.
