The KSK afterburner chamber
The KSK (post-)combustion chamber, dust chamber, or drop-out box is located directly downstream of the first component of the primary gas extraction system. The exhaust gas is diverted and stabilized at this point. In the process, coarse dust particles are removed from the exhaust gas and collected so that they can be efficiently removed later. This significantly reduces the load on the subsequent sections of the hot gas duct and the filters.
Modular design.
Our afterburners are typically designed as water-cooled tube structures—though other designs are also possible. Due to the varying spatial conditions at each site, no two of our afterburners are alike. However, the vast majority of combustion chambers share the common feature of a modular design, consisting of several water-cooled panels that can be replaced individually as they wear out.

What is flue gas cleaning and why is it important?
KSK’s flue gas cleaning typically involves the primary or direct dust removal from a plant. For an electric arc furnace, the flue gas cleaning system thus usually consists of a furnace cover elbow, an afterburner chamber with dust discharge, and a hot gas duct. Since our systems are designed as water-cooled pipe structures, the flue gas is cooled by the cooling water flowing through the pipes. In the converter area, steam is generated on the pipe side as part of the flue gas cooling process.
We design our primary dust removal systems so that they can be integrated into your existing system with secondary dust removal and a filter plant upon request. If you are planning a completely new flue gas cooling system, we are happy to assist you or potential project partners as experts in primary gas dust removal. Upon request, we develop flue gas cooling systems as cold- or warm-water components, or as hot-water components or steam generators. Geometrically, there are few limits to KSK’s flue gas cooling systems—in any case, they are always custom-made.
Effective Flue Gas Cleaning: Everything You Need to Know
Flue gas cleaning is a critical technology in industry and power generation that aims to minimize environmental impact from the emission of pollutants. Various processes and technologies are used to remove harmful components from flue gases in order to improve air quality and comply with legal regulations. In this article, we will explain the fundamental aspects of flue gas cleaning, the pollutants to be removed, how the systems work, legal requirements, and challenges.
Definition and Basics of Flue Gas Cleaning
Flue gas cleaning is the process of removing pollutants from flue gases produced during the combustion of fossil fuels in boilers, steel mills, and other industrial facilities. This cleaning is necessary to protect the environment and human health by minimizing the emission of hazardous substances. Flue gas cleaning processes involve the use of various technical systems and chemical reactions to either physically separate the pollutants or chemically neutralize them.
Why flue gas must be cleaned
Flue gas contains a variety of pollutants, including gaseous substances such as sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and volatile organic compounds, as well as solid particles and dust particles. These pollutants can cause serious environmental problems, such as acid rain, smog, and adverse health effects in humans. Therefore, flue gas cleaning is essential to minimize these risks. Additional benefits of flue gas cleaning include compliance with legal requirements and the avoidance of financial penalties for exceeding established limits.
Key Components of a Flue Gas Stream
A typical flue gas stream consists of various components, including water vapor, carbon dioxide (CO₂), nitrogen, and water, as well as a mixture of harmful substances. The exact composition depends on the type of fuel and the combustion conditions. In addition to non-hazardous components such as nitrogen and water vapor, the flue gas stream also contains gaseous pollutants and heavy metals harmful to health, such as mercury and dioxins. These must be efficiently removed through flue gas cleaning before the cleaned gas is released into the atmosphere.
Which pollutants are removed during flue gas cleaning?
Particles and dust particles
Dust particles are small, solid particles produced by the combustion of fuels that are released into the atmosphere along with flue gases. These dust particles can cause health problems such as respiratory diseases and pollute the environment by settling in soil and water. Flue gas cleaning systems use various mechanisms, such as electrostatic precipitation or filtration, to remove these particles from the flue gas stream.
Dioxins and Heavy Metals
Dioxins and heavy metals such as lead, mercury, and cadmium are particularly hazardous pollutants that are often released during industrial combustion processes. These substances can accumulate in the environment and lead to health problems such as cancer or neurological disorders. In flue gas cleaning, special separation and adsorption processes are used to remove these highly toxic compounds. For example, heavy metals can be converted into stable compounds by adding chemicals and then adsorbed or separated.
Gaseous pollutants such as sulfur dioxide and nitrogen oxides
Sulfur dioxide and nitrogen oxides are major components of the flue gases produced during the combustion of fossil fuels. These substances contribute significantly to the formation of acid rain and smog. Flue gas cleaning employs processes such as absorption to neutralize sulfur dioxide using alkaline scrubbers. Nitrogen oxides are often converted into nitrogen and water through selective catalytic reduction (SCR) with the addition of ammonia to minimize environmental impact.
How do flue gas cleaning systems work?
Mechanisms of Separation and Adsorption
The removal of pollutants from flue gas can be based on various physical and chemical mechanisms. Electrostatic precipitation uses electric fields to remove particles from the flue gas stream. Adsorption, on the other hand, refers to the attachment of pollutant molecules to the surface of a solid material, thereby removing them from the gas. Activated carbon is a typical adsorbent that is frequently used to remove organic pollutants and heavy metals.
Absorption and Adsorption Techniques
Absorption and adsorption are fundamental techniques in flue gas cleaning. In absorption, gaseous pollutants are dissolved in a liquid. An example is the removal of sulfur dioxide through an alkaline scrubbing process. In adsorption, on the other hand, pollutant molecules adhere to the surface of an adsorbent such as activated carbon. Both techniques are often used together to achieve maximum cleaning efficiency.
Electrostatic Precipitation and Dust Removal
Electrostatic precipitation is an efficient method for removing dust particles from flue gases. In this process, the particles are charged by electric fields and then collected and separated on oppositely charged plates. This method is frequently used in power plants and industrial facilities. Dust removal can also be achieved using mechanical filters and cyclones, which separate the particles from the gas stream using centrifugal force or physical barriers.
What are the legal limits and regulations?
Overview of the BImSchV
The Federal Immission Control Ordinance (BImSchV) establishes the legal limits for the emission of pollutants into the environment. This ordinance serves as the basis for flue gas cleaning and ensures that emissions from industrial plants and power plants are reduced to a minimum. The BImSchV includes various stages and specific regulations for different pollutants such as sulfur dioxide, nitrogen oxides, and heavy metals.
Measurement and Compliance with Limit Values
Compliance with legal limit values requires regular measurements of pollutant concentrations in flue gas. These measurements are performed by continuous emission monitoring systems, which provide accurate data on pollutant emissions . Operators of flue gas cleaning systems are required to document this data and submit it to the authorities to ensure compliance with regulations.
Penalties for Exceeding Limit Values
Severe penalties may be imposed if the specified limits are exceeded. These range from fines to the closure of the facility. To avoid these consequences, many companies rely on advanced flue gas cleaning technologies and strict internal monitoring mechanisms. In addition, regular maintenance and optimization of the systems can help ensure compliance with the limits.
What are the challenges of flue gas cleaning?
Effective removal of heavy metals and dioxins
One of the greatest challenges in flue gas cleaning is the effective removal of heavy metals and dioxins. These pollutants are particularly difficult to break down and require specialized processes for safe and complete separation. Technologies such as activated carbon adsorption and catalytic processes are frequently used, but the efficiency of these methods must be continuously improved to meet strict legal requirements.
Use and recycling of captured materials
Another important aspect is the use and recovery of separated materials. To minimize environmental impact, the collected pollutants must be safely treated and disposed of or, in some cases, recycled. Materials such as heavy metals, for example, can be converted into new resources rather than simply being landfilled. Innovations in this area can help improve both the environmental performance and the economic efficiency of flue gas cleaning.
Optimization of flue gas cleaning processes
Finally, there is a constant challenge to optimize flue gas cleaning processes. This requires continuous research and development as well as the implementation of new technologies. The goal is to increase the efficiency of pollutant capture and neutralization, minimize the energy consumption of the systems, and simultaneously reduce operating costs. Close collaboration between industry, research institutions, and policymakers is necessary to achieve these goals and protect the environment sustainably.
