Fuel Tech’s NOxOUT® SNCR technology is a world-leading solution engineered to cost-effectively remove nitrogen oxide from stationary combustion sources. This advanced in-furnace technology employs a multi-level, automated system that injects urea into the optimal temperature zones of a furnace or boiler, ensuring maximum reduction of nitrogen oxide. Our SNCR technology is deployed on installations globally, across a diverse range of applications including coal, oil, natural gas, waste-to-energy and biomass.
AIR POLLUTION CONTROL
NOxOUT® Selective Non-Catalytic NOx Reduction (SNCR)
Benefits and Features
- 25-50% nitrogen oxide (NOx) reduction
- Injection of aqueous urea or aqueous ammonia
- Multiple nozzle lances for large furnace applications
- Combined injection strategy to control ammonia slip
- Over 630 installations worldwide
Leveraging computer modeling to optimize outcomes
Fuel Tech’s SNCR systems use CFD models and chemical kinetics modeling to optimize outcomes. Our NOxOUT SNCR technology is sufficiently flexible to apply to a variety of commercial and process combustion units. A key advantage of our NOxOUT systems is the way they can easily be integrated with other nitrogen oxides reduction technologies.

Meeting BACT and RACT compliance requirements
Fuel Tech’s NOxOUT process meets Best Available Control Technology (BACT) compliance requirements for municipal solid waste combustors, as well as coal-fired Independent Power Producer (IPP), and fluidized bed boilers. The SNCR process has also been used to comply with Reasonably Available Control Technology (RACT) requirements in ozone non-attainment areas and administrative compliance orders in specific locales.
Fuel Tech offer a comprehensive NOx reduction solution
Our comprehensive range of nitrogen oxide (NOx) reduction technologies offers seamlessly integrated systems, with minimal operational disruption and optimized cost-efficiency. Technologies that have been retrofit with the NOxOUT process include SCR systems, low nitrogen oxides burners, over-fire air, combustion tempering, neural network controls, and gas reburn systems. Our NOxOUT installations have delivered exceptional results for our clients, achieving NOx reductions of over 70% in some cases. The wide range of capabilities we offer allows us to approach each application as a solutions provider rather than an equipment supplier, ensuring effective NOx control from combustion to stack.
