Emissions Control

B&W is an innovator and industry leader in providing advanced air emissions control and energy recovery equipment and technologies for power plants and industrial processes.

B&W provides GMAB™ flue gas cleaning and flue gas condensation technologies for applications such as waste-to-energy, co-incineration and hazardous waste incineration plants with the potential to increase energy efficiency.

Solvent-based scrubbing technologies, like B&W’s SolveBright™ process, often require reductions in various pollutants found in the incoming flue gas. Pre-treatment of the flue gas is vital for the operation and economics of the process to result in the optimum effectiveness of the carbon capture technology.

We can tailor a multi-faceted mercury control solution that considers many variables, such as the existing or planned emissions control system, fuel, flue gas composition, flyash characteristics, stack mercury limits and many other operational factors.

B&W’s proven suite of NOx control solutions includes selective catalytic reduction (SCR) and non-catalytic reduction (SNCR) technologies, low-NOx burners, and combustion air staging with overfire air ports, all key components of an overall NOx reduction strategy.

B&W has extensive experience with both dry and wet electrostatic precipitator (ESP) technologies, and fabric filter baghouses. Our proven solutions are removing fine and coarse particulate in a wide range of applications, including power generation, waste-to-energy, cement, chemical, oil & gas, pulp & paper, metals/steel, and others.

B&W offers a variety of solutions for the removal of acid gases such as sulfur oxides (SO2 and SO3), hydrogen chloride (HCl), hydrogen fluoride (HF) and other hazardous air pollutants (HAPs).

B&W offers both fully assembled installations and subsystems for cleaning flue gases generated by the incineration of municipal and industrial waste and the combustion of biofuels.

For coal-fired power generation applications, B&W's spray dryer offers true zero liquid discharge by using the latent heat of the boiler flue gas to evaporate the entire wet FGD waste stream. We also provide solutions to mitigate discharge water from wet flue gas desulfurization (FGD) wastewater applications.

B&W supports environmental system upgrades, services and replacement parts for equipment originally supplied by us as well as other manufacturers.

Developed by ExxonMobil in the 1970s and now licensed by B&W, wet gas scrubbing technology removes particulates and sulfur dioxide (SO2) by intimate mixing of the flue gases with an aqueous scrubbing liquid. The technology can also be enhanced to meet tighter restrictions on nitrogen oxides (NOx) or particulate. This well-proven technology provides refiners with numerous advantages for maximum FCC unit availability.
