Amec Foster Wheeler offers a complete portfolio of NOx reduction technologies and solutions, beginning with cost effective mill and combustion system upgrades to full retrofits of selective catalytic reduction systems. We create custom, high value solutions to meet NOx reduction goals. <br/><br/> <b>Selective catalytic reduction (SCR) systems</b><br/> We have supplied over 130 selective catalytic reduction (SCR) systems globally for a variety of applications from large-scale pulverized-coal utility boilers, through industrial process heaters and boilers, to combustion turbines. In fact, we supplied the first four SCR systems on utility plants in the US. <br/><br/> As a boiler manufacturer, we can assess the operational impacts of an SCR installation including modified flue ducting, economizer bypass, fan impacts and more. And as a construction, engineering and equipment company we can supply the complete SCR system on a turnkey basis. <br/><br/> Our professionals apply the latest research, design, engineering, construction and management resources to provide single-source project execution. We know which catalyst to use for which fuel, boiler type, and NOx reduction target. <br/><br/> <b>Combustion upgrades</b><br/> Amec Foster Wheeler employs a systems approach to the development of combustion-related products. From the pulverizers to the furnace, all components contribute to the final thermal and emissions performance of the boiler. This approach considers the primary air system, pulverizer performance, fuel line balancing, secondary air duct/windbox flow conditions and the boiler’s configuration, as a total integrated system. <br/><br/> <b>Low NOx burners (LNB)</b> <ul> <li>Tangential low NOx (TLN) burner <li>Vortex wall low NOx burner <li>Arch low NOx burner</li> </ul> <br/> <b>Overfire air systems (OFA)</b> <ul> <li>Dual zone OFA <li>Optimisation of secondary air distribution</li> </ul> <br/> <b>Fuel/air control systems</b> <ul> <li>Electric charge transfer (ECT) systems <li>Windbox air balancing and control <li>Computation fluid dynamic (CFD) modeling <li>Adjustable coal flow and distribution devices</li> </ul> <br/> <b>Pulverizer upgrades</b> <ul> <li>Dynamic classifiers <li>Performance upgrades <li>Fuel changes</li> </ul>

Amec Foster Wheeler’s acid gas control technologies offer proven, high value solutions to control SO<sub>2</sub> and acid gas emissions. We engineer systems that are custom designed to meet increasingly more stringent air quality control regulations. Whether your application is removing SO<sub>2</sub>, HCl, SO<sup>3</sup>, heavy metals (HF) from power plant or industrial flue gases, our technologies can respond to your specific needs. <br/><br/> Our commitment is to provide you with the highest quality service which doesn’t stop once your system goes into operation. We can design and deliver an extended service program or a stand-alone replacement parts program to address your needs and keep your system operating at peak performance. <br/><br/> <b>Wet flue gas desulfurisation (FGD) systems</b><br/> Our FGD systems have been successfully operating in the power, municipal solid waste, steel, aluminum and other processing industries for more than 40 years. We offer both open spray (single and double loop) tower and dual-flow tray wet FGD designs. <br/><br/> <b>Spray dry absorbers (SDA)</b><br/> Our proprietary two-fluid nozzle SDA design makes efficient use of reagents and energy while providing a highly reliable atomising system. Their benefits include: <br/><br/> <ul> <li>High acid gas removal (SO<sub>2</sub>, SO<sup>3</sup>, HCI, HF) <li>Heavy metals control with activated carbon <li>Recycle to improve lime utilisation</li> </ul> <br/> <b>Dry sorbent injection (DSI) systems</b><br/> Our DSI systems are an economical, reliable solution when your plant requires lower levels of SO2 and acid gas emission control. DSI systems can control:<br/><br/> <ul> <li>CI / HF <li>SO<sub>2</sub>, SO<sup>3</sup> <li>Heavy metals</li> </ul>
Amec Foster Wheeler’s fabric filter (FF) and electrostatic precipitator (ESP) equipment has been utilised on a wide range of applications in utility and industrial processes. We continue to serve our clients with the most experienced technical staff in the air pollution control industry, offering advanced equipment and a level of service few other air pollution control companies can match.<br/><br/> <b>Electrostatic/Dry electrostatic precipitators (ESP/DESP)</b><br/> Since our first dry ESP installation in 1951, our record of technological firsts include the introduction of the Rigid Frame Electrostatic Precipitator to North America in 1965. Today, our technology encompasses all major designs in electrostatic precipitators to clean gases from industrial and utility processes.<br/><br/> Designs include our HaRDETM system with tumbling hammer rapping and our VIGR system with gravity impact rapping. Both designs include our virtually unbreakable rigid discharge electrodes for increased performance and enhanced reliability with a full insulator penthouse for ease of maintenance.<br/><br/> And with our extensive experience on many different types of dry ESPs, we are able to provide unique solutions for rebuilds and retrofits.<br/><br/> <b>Wet electrostatic precipitators (WESP)</b><br/> Wet ESP technology was first developed in 1907 to control sulfuric acid mist from a copper smelting process. It has since been proven in both industrial and utility applications around the world.<br/><br/> Unlike dry ESPs, a wet ESP cleans the collection surfaces with water. Washing the collection surface prevents resistivity and re-entrainment issues and allows for higher operating power levels and increased capture of sub-micron particles.<br/><br/> Designs include our HIPWESP design for larger gas volumes and our Condensing WESP design. Both designs include a continuously irrigated collecting electrode which offers superior performance to spray-clean designs.<br/><br/> <b>Fabric filters</b><br/> Amec Foster Wheeler’s pulse jet dust collectors have made important contributions over the years to controlling emissions for the iron, steel, non-ferrous, coal-fired utility, hazardous waste and trash-to-energy industries. Our jet technology offers a variety of designs, both custom and pre-engineered, to meet specific needs. Each system is designed for cost effective, reliable performance. Designs include our intermediate pressure Jet VIP pulse jet fabric filter and our high pressure Jet III. Both designs utilize “tuned” pulse cleaning systems for low cleaning frequency and long bag life.<br/><br/> Amec Foster Wheeler also offers our Dustube reverse air and shaker design collectors with low energy, gentle cleaning. This method of cleaning allows for long filter bag life. We offer both field-assembled designs and modular designs, and various cell plate attachments and bag suspension designs to suit each application.<br/><br/> <b>Cartridge collector (CC)</b><br/> The cartridge collector (CC) is our standardised pleated cartridge collector for low temperature industrial ventilation applications. This standardised, modular design fits a wide range of industrial applications. It utilises an optimised pulse cleaning system, with variable-hole manifold pipes and venturi, highly efficient gas flow distribution, a heavy duty, all welded construction and patented locking cartridge access.
