Particulate and Acid Mist Control

Wet and dry ESPs and fabric filters

Wet ESPs

For utility and power generation applications, there has been renewed interest in the use of wet ESPs to control selected emissions, especially sulfuric acid mist (H2SO4) and fine particulates. Features and benefits of B&W’s wet ESP system includes:

  • Low operating and maintenance costs
  • Ultra low particulate (solids, mist and fine particulate) emissions
  • Hazardous pollutant reduction
  • Optimized system design for sorbent injection technologies
  • Total system capability for integration with other pollution control devices
  • Well suited for new boiler installations as well as retrofit applications

For industrial installations, the wet electrostatic precipitator provided by B&W offers highly efficient control of submicron particulate, heavy metals, acid mists and condensed metal fumes and organics.

Dry ESPs

Regardless of the application, B&W’s latest dry ESP design provides many advantages, including:

  • High efficiency
  • High temperature capacity
  • Wide capacity range
  • Low maintenance
  • Quality mechanical and electrical components for long life
  • Advanced controls and software for optimum operation

B&W's experience in industrial emissions control is among the longest and broadest in the industry. Our particulate control experience originated with one of the first commercial applications of industrial ESPs in the United States in 1907.

ESPs for Diverse Applications

B&W Environmental has extensive experience with both dry and wet technologies, and have installations in a wide range of applications, including power generation, waste-to-energy, cement, chemical, oil & gas, pulp & paper, metals/steel, and others.

In this video, our Precipitator Expert John returns to talk about powerful precipitators for wood-fired applications. He discusses the most significant improvements he has seen in his career and one diagnostic check he recommends on an operating ESP.


Pulse Jet Fabric Filters

Pulse Jet Fabric Filters

B&W has supplied some of the largest and most efficient pulse jet fabric filters in the world. Our design innovations offer features not available from other suppliers, such as our long bag (10 meter) technology, enhanced pulse system, and online maintenance capability. Our fabric filters, or baghouses, offer high particulate removal efficiencies, reduced maintenance costs, and reduced operating costs. Integrating fabric filters with our sorbent injection and flue gas desulfurization (FGD) technologies also provides high removal efficiencies of hazardous air pollutants in a variety of applications. It can also be used with an electrostatic precipitator (ESP) for greater mercury (Hg) control. Our innovative fabric filter technology can be found in a variety of industries including steel, cement, incineration and steam generating boilers that utilize a variety of fossil- and biomass-based fuels.
