The Air We Breathe

Emissions Control Technologies  

Today, air pollution is a big topic across the globe as government ministries in Southeast Asia and other regions partner with the EPA to strengthen support for environmental laws and improve air quality.

Multi-pollutant control strategies are integrated to optimize overall plant emissions levels and help meet air emissions requirements. With a half a century in emissions reduction expertise behind us, B&W Environmental is ready to Clean Air Asia and beyond.

Carbon Capture

Reducing the Impact of Climate Change

B&W has led the industry in carbon capture technology research, development and demonstration - initially for the global coal installed base. Our "near zero" emissions solutions include both oxy-coal combustion technology and RSAT™ post combustion technology. 

Additionally, we're collaborating with The Ohio State University to support U.S. DOE-sponsored pilot testing of coal-direct chemical looping, a promising carbon-friendly power technology that produces an exhaust stream of pure CO2 and water. Lab-scale results show great promise in meeting the U.S. DOE’s carbon capture efficiency and cost targets. This next generation CO2 capture technology shows promise beyond power generation into other industrial applications.

Dioxin Removal

Innovative Material for Dioxin Removal

Dioxins are highly toxic substances and can be formed when waste is incinerated. There are, therefore, very strict requirements set for their low emissions. 

Through our GMAB product line, B&W offers ADIOX® technology, a dioxin removal solution which has been proven in more than 100 installations worldwide. The technology is effective, safe and economical for reducing emissions of dioxins in waste, biomass, metal, chemical and other industries.

Advanced NextBAT Clean Energy Technologies

NextBAT Waste-to-Energy Technologies

Best Available Technologies for EU Waste Incineration BREF Compliance

Babcock & Wilcox has a long tradition of focusing on high efficiency and low emissions.  Our renewable and environmental segments, together, have an integrated systems solution for the next generation of waste-to-energy plants The Waste Incineration BREF sets new and higher standards for waste-to-energy plants.  

A waste-to-energy plant’s level of efficiency in recovering energy from waste is measured by the R1 formula. High overall energy efficiency ensures maximum substitution of fossil fuels and thereby reduces the impact of greenhouse gases. B&W's NextBAT® solution ensures that plant owners achieve a high R1 rate because of our unique technologies. 

  • Proven, proprietary DynaGrate® combustion grate offers high reliability, maximizing waste throughput and MW output

  • Advanced NextBAT technology provides a thermal efficiency of 99% and 95-99% clean flue gas

  • NextBAT meets the EU BREF requirements

Leaving PM Emissions in the Dust

In the January 2021 edition of International Cement Review, B&W electrostatic precipitator guru John Knapik offers a solution to further reduce particulate matter on marginally performing ESPs.

Newer top-rapped precipitator designs offer distinct advantages over tumbling hammer designs for improving performance and maintainability. The article highlights these advantages and how to achieve them through a conversion. Having performed more than 50 tumbling hammer ESP rebuilds of this kind– B&W Environmental is well positioned to help the cement and other industries meet challenging emissions limits.

Power Plant Bottom Ash Handling

The challenge to effectively and reliably meet regulatory targets for bottom ash handling has often required plant operators to make significant investments in equipment modifications.

We set out to develop a new conveyance technology that met effluent limitation guidelines (ELG) and coal combustion residuals (CCR) requirements while minimizing modifications to the existing footprint. The result? B&W’s patented and proven its Allen-Sherman-Hoff® Submerged Grind Conveyor (SGC) system.


Basics of ESP Operation 

An electrostatic precipitator (ESP) is an effective method of particulate collection in power generation applications. Its history dates back to the early 20th century. Of course, technology upgrades to enhance performance have continued for nearly as long. We have prepared a two-part article discussing ESP operation and some of the available upgrades and modifications now available for new and existing installations.

Upgrades to Existing Wet FGD Systems 

Upgrading an existing wet FGD system may be an effective way to improve SO2 removal, allow the use of lower cost higher sulfur coals, reduce power consumption, allow for the use of an alternate, lower-cost reagent, and improve the reliability of the system while reducing the operating and maintenance costs.

Factors that Affect ESP Collection Efficiency and Ways to Improve Performance

In Part 1, we reviewed the basics of ESP operation. This article explores design and operational problems that will negatively affect the collection performance of an ESP. It will also outline potential modifications to help improve performance and efficiency.


TransAlta Keephills Generating Station – Alberta, Canada

Spray dryer absorber, pulse jet fabric filter and mercury control systems result in high SO2 removal efficiency and low operation and maintenance costs

Lansing Generating Station - Iowa, USA 

Circulating dry scrubber (CDS) designed, installed and integrated with fabric filter achieves SO2 removal efficiency up to 98%

Landskrona – Sweden

Multi-fuel combined heat and power plant project included an SNCR, semi-dry flue gas cleaning with fly ash system and residual silo.


Our suite of emissions control and environmental technology solutions are engineered and proven to help preserve our earth’s natural resources.

These include cooling systems, ash and material handling, chemical looping for carbon control, wastewater treatment, and state-of-the-art equipment for reducing particulate, mercury, nitrogen oxides, sulfur dioxides, acid gas and other emissions.
