Pure environmental sustainability

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.

More solutions for less pollution.


Submerged Grind Conveyor

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 not only met effluent limitation guidelines (ELG) and coal combustion residuals (CCR) requirements, but also considered unique plant layouts in providing a simplified and more cost-effective solution. The result? B&W’s patented and proven its Allen-Sherman-Hoff® Submerged Grind Conveyor (SGC) system, which offers maximized results and minimized modifications to the existing footprint.

In this SGC technology success story, B&W collaborated with a Colorado, USA power producer to comply with the CCR rule and other pending legislation aimed at mitigating environmental risks associated with long-term storage of ash in impoundments.


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.

The Air We Breathe

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

B&W is 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.

NextBAT® - Crane to Stack​

The purpose of a flue gas cleaning system is to reduce atmospheric emissions of substances hazardous to the environment and health. This includes heavy metals, dioxins and substances that cause acidification and eutrophication.

NextBAT® is the Scandinavian solution to the next generation of Best Available Technology – a solution for future Waste-to-Energy plants offering exceptionally low emissions and will meet the requirements of waste incineration BREF.
