The NOxOUT process has enabled municipal waste units, to cost effectively meet their NOx reduction requirements. Fuel Tech’s Dissolved Gas Infusion (DGI) technology can treat wastewater to comply with the legal requirements of the Resource Conservation & Recovery Act (RCRA) developed by the US Environmental Protection Agency (EPA). While aeration is a common method of treatment, most equipment is not designed to be resilient in harsh conditions and maintenance can be both expensive and dangerous. DGI has been engineered to perform reliably in challenging environments, and respond to meet highly variable oxygen demands with efficiency and precision.
MUNICIPAL WASTE & WASTEWATER
Robust reliable equipment designed for harsh environments
Fuel Tech’s NOxOUT technology has been applied on approximately 200 waste to energy units, where SNCR has often been considered a Best Available Retrofit Technology.
Selective Non-Catalytic NOx Reduction (SNCR) Technology
Our NOxOUT® SNCR technology is designed to cost-effectively reduce nitrogen oxides (NOx) from stationary combustion sources. This intelligent, in-furnace technology uses multiple levels of injection of stabilized urea liquor into the optimal temperature zones inside a furnace or boiler, to optimize the reduction of nitrogen oxides. SNCR can be used by utilities firing coal, oil or natural gas, and by waste-to-energy and biomass applications.
Performance
- 25 – 50% NOx Reduction
- NOx outlet emissions of 0.10lb/MMBtu or below
Features:
- Injection of aqueous urea or aqueous ammonia
- Multiple nozzle lances for large furnace applications
- Combined injection strategy to control ammonia slip
DGI® Dissolved Gas Infusion
DGI combines best-on-the-market oxygen transfer efficiency with precision accuracy, to deliver an energy-efficient and cost-effective solution for use in water and wastewater treatment systems. This cutting-edge technology achieves rates of 99+% gas transfer by pre-dissolving high purity gas in a separate pressurized slipstream using a plunging jet saturator. The slipstream can reach up to 900mg/l oxygen concentration; it is then added to the main volume of water and diluted to meet precise specifications.
Benefits:
- Effective, flexible and environmentally friendly
- DGI combines a patented infusion vessel and patent-pending injector array to ensure effective dissolved oxygen (DO) delivery
- Highest oxygen transfer efficiency available on the market
