Different Types of Flue Gas Treatment Equipment

How Does a Flue Gas Treatment System Work?

How Does a Flue Gas Treatment System Work?

The complete flue gas treatment process may include gas collection, filtration, desulfurization, denitrification and final purification, depending on the pollutants and emission targets.

1. Flue Gas Capture and Pre-Treatment

Flue gas is collected through hoods and ducts, then cooled or conditioned when necessary to protect downstream equipment and stabilize operation.

2. Fine Particulate Filtration

Fine dust is removed through bag filters, electrostatic precipitators or other flue gas filtration equipment selected according to gas and dust characteristics.

3. SO₂, NOx and Acid Gas Control

A flue gas desulfurization system removes SO₂ and acid gases, while a flue gas denitrification system controls NOx through SCR, SNCR or other suitable technologies.

4. Final Purification and Discharge

Residual pollutants may be treated through adsorption or fine filtration. The cleaned gas is then monitored and safely discharged through the stack.

Industrial Applications of Flue Gas Treatment Systems

Tianshun provides customized industrial waste gas treatment solutions for production processes that generate dust, SO₂, NOx, acid gases and other pollutants. Typical applications include:


  • Industrial silicon and ferroalloy furnaces

  • Steel and non-ferrous metallurgy

  • Industrial boilers and power generation

  • Cement, lime and high-temperature kilns

  • Waste incineration and waste-to-energy plants

  • Chemical and material processing

  • Mining and mineral processing


Each exhaust gas treatment system is configured according to the production process, pollutant composition, flue gas parameters and required outlet emission levels.


How to Choose the Right Flue Gas Treatment System

Selecting the right flue gas treatment system depends on the pollutants, gas conditions, production process and required emission limits. Tianshun configures suitable flue gas treatment technologies according to each project’s operating requirements.

  • High-Dust Applications: Bag filters, electrostatic precipitators or cyclone systems for industrial furnaces, silicon processing and material handling.

  • SO₂ and Acid Gas Control: Wet, dry or semi-dry desulfurization equipment selected according to sulfur concentration and water availability.

  • NOx Emission Control: SCR or SNCR systems for boilers, kilns and other high-temperature processes.

  • Multi-Pollutant Treatment: An integrated exhaust gas treatment system combining filtration, desulfurization, denitrification and final purification.

  • Retrofit Projects: Modular emission control equipment designed around existing ducts, plant space and available utilities.

To recommend a suitable system, provide the flue gas flow, temperature, pollutant concentrations, operating hours and required outlet limits.
