Decarbonization for a Net Zero Future

More than 100 countries around the globe are committed to a carbon net-zero goal by mid-century. The world wants and needs to take action now to reduce the impact of greenhouse gas emissions on our atmosphere. With more than 90 active patents for carbon capture, B&W has been a leader in the research and development of decarbonization technologies for more than four decades. Building upon successful conceptual research and demonstration work, B&W is positioned to CO2llaborate 2 Decarbonize

Our revolutionary ClimateBright™ decarbonization technologies can capture carbon pre-combustion, post-combustion — and even in-situ — from conceptual research to commercial installation globally. We collaborate with universities and partners in the pursuit of best-in-class decarbonization technologies. Our proven systems work with a vast array of feedstock, such as natural gas, biomass, petroleum coke, coal, municipal solid waste and syngas.

New and retrofit applications:

  • Electric power generation
  • District heating and cooling
  • Emissions control
  • Waste-to-energy
  • Hydrogen production 

A wide variety of industries:

  • Steel
  • Power
  • Cement
  • Oil and gas
  • Food manufacturing
  • Carbon black
  • Pulp and paper

The air we breathe

The Air We Breathe

Emissions Control Technologies  

Today, air pollution is a big topic across the globe. With a half a century in emissions reduction expertise behind us, B&W Environmental is the clear choice for clean air.

We offer integrated multi-pollutant control strategies to optimize overall plant emissions levels and help meet air emissions requirements. 

B&W Environmental A-S-H Submerged Grind Conveyor for Ash Handling

Bottom Ash Handling

Effluent Limitation Guidelines 

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.

NextBAT® - Crane to Stack​

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.

The Next Generation of Waste Incineration

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

ESP Basics

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 to Improve Performance, Reduce Operating and Maintenance Costs and Improve Reliability

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
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.
