Air Quality Control Systems (AQCS)

Our AQCS technologies are suitable for power generation and industrial applications, including aluminum, iron and steel, oil and gas, cement, waste-to-energy, biomass, pulp and paper, and nonferrous metals, among others.


A Pioneer in Air Quality Control for Power and Industrial Applications

We have provided our customers with advanced Air Quality Control Systems (AQCS) for more than 80 years. GE’s expertise, technology, and comprehensive product portfolio enable our customers to comply with today’s stringent emission regulations for particulate and gaseous pollutants emitted from power plants and industrial operations. Our high-quality and cost-effective equipment and services can be adapted to our customers’ needs.

Customized Offerings

With GE, customers receive a wealth of air quality control know-how. For new builds and upgrade and retrofit of existing AQCS, we offer on-demand solutions tailored to meet our customers’ requirements, including partial or full scope as described below:

Engineering: GE offers advanced air pollution control engineering, from process and equipment design to construction, operations, and maintenance.

Equipment supply: Our comprehensive AQCS portfolio of products covers a broad range of pollutants with industry-leading technology with a single process or a combination to cover the entire flue gas chain. This gives customers the flexibility to address complex interactions between components and processes.

Construction and commissioning: We offer:

— Construction management

— Commissioning management

— Construction and commissioning advisory services

Inspection and maintenance: We provide these services for our own fleet and/or other AQCS solutions.

Innovative Products and Technologies

Since 1983, our technology center in Växjö, Sweden—one of the largest in the world in the field of environmental control solutions—has been at the forefront of advanced research and development for air quality and CO2 control solutions. Focusing on technology innovation and product validation, it has test halls for pilot operations and flow modeling, an analytical laboratory specializing in particle and environmental analyses, an instrument workshop, high voltage facilities for ESP electrical testing (SIR, T/R sets), and a mechanical workshop for pilot equipment manufacturing.

Particulate Control: Fabric Filters

For particulate removal, fabric filters offer a flexible alternative to electrostatic precipitators (ESPs), particularly when dust characteristics are challenging or variable.
