Services need to be run as cost-effectively as possible, while meeting all statutory pollution emissions targets. The sector is under increasing pressure from rising demand driven by population growth and the escalating impact of climate change. Fuel Tech has designed a portfolio of advanced technologies to meet these challenges, with a focus on improving process efficiencies, reducing operating costs, and controlling air emissions.
UTILITY POWER
Improving efficiencies and meeting air emission compliance
The utilities sector delivers vital services for the economy. Reliability of these services is critical, and any interruptions can have serious consequences for customers and may trigger significant regulatory penalties.
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
Selective Catalytic Reduction (SCR) Technology
SCR is a post-flue gas treatment technology designed to dramatically reduce nitrogen oxide (NOx) emissions from a wide variety of boiler types. Fuel Tech combines extensive design experience with a real-life understanding of plant operations, to maximize performance and minimize the impact on energy production. SCR is used on coal, biomass, oil, natural and waste gases, municipal and hazardous waste.
Benefits:
- Guaranteed NOx reduction performance
- Proven expertise to optimize existing SCR systems using flow modeling, flow control devices and ammonia injection grid modifications
- Dramatically improving efficiency using CFD modeling
ULTRA® Urea Thermal Decomposition Technology
The ULTRA process safely generates high-quality, diluted ammonia for SCR systems and flue gas conditioning applications, by thermally decomposing urea. This ensures a safe, reliable source of ammonia that can be instantly generated onsite when needed. ULTRA can utilize electric heaters, natural gas burners, external flue gas heat exchangers, or the direct use of flue gas as the heat source.
Benefits:
- Capacity of 1.0 to 1,300lbs per hour of ammonia supply
- ULTRA can utilize urea solution concentrations of 32% to 55% by weight and varying levels of urea quality
- Eliminates the risks associated with the transport of storage of hazardous ammonia
- Experience on over 350 applications worldwide
Electrostatic Precipitator (ESP) Enhancement Technologies
The rehabilitation or upgrade of existing ESPs is a cost-effective means of improving the performance and restoring the efficiency of aging equipment, as well as enabling compliance with particulate emission levels.
Benefits:
- Minimizes capital expenditure
- Eliminates downtime risk from installing new equipment
- Ease of integration into the balance of plant
Flue Gas Conditioning
Significantly boosts the performance of ESPs and radically improves the capture of fly ash and particulates. The technology works by injecting trace amounts of sulfur trioxide (SO3), and in some cases ammonia, into flue gas to improve operation of ESPs without increasing emissions.
Benefits:
- Reduces fly ash resistivity
- Improves fine particulate capture reducing opacity and emissions
- Installation costs reduced by designing modular equipment
- Proven technology with over 500 FGC systems installed on ESPs worldwide
Chemical Technologies
Our chemical technologies improve boiler efficiency and reduce greenhouse gas emissions by controlling slagging, fouling and corrosion, along with reducing hazardous air pollutants including mercury, acid emissions, and fine particulate matter (PM2.5) formation.
Benefits:
- Increases profits by enabling plants to reduce the quality of fuel required
- Helps increase reliability and reduces boiler de-rate outages
- Creates energy efficiency gains and heat rate improvements
- Reduced maintenance costs for slag removal
