Fluegas, also known as flue gas, refers to the gaseous emissions produced during the combustion of fuels in industrial processes, power plants, and heating systems. It primarily consists of combustion products such as carbon dioxide (CO2), water vapor (H2O), nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter, and trace gases. The composition of flue gas varies depending on the type of fuel burned and the combustion conditions.

In thermal power plants, especially those fueled by coal, oil, or biomass, flue gases are emitted through a stack or chimney after passing through various pollution control devices. These devices include electrostatic precipitators, fabric filters, scrubbers, and selective catalytic reduction systems, which aim to reduce pollutants before release into the atmosphere. Proper management of flue gases is crucial for air quality and environmental health, as many of their constituents contribute to air pollution, acid rain, and climate change.

Flue gas treatment technologies focus on removing or neutralizing harmful components, especially sulfur oxides and nitrogen oxides, to meet environmental regulations. Carbon capture and storage (CCS) techniques are also employed to reduce CO2 emissions from flue gases, addressing climate change concerns.

Monitoring and analyzing flue gases is vital in assessing the efficiency of combustion processes and the effectiveness of pollution control measures. Analytical methods include gas chromatography, infrared spectroscopy, and continuous emission monitoring systems.

Overall, flue gases are an unavoidable byproduct of combustion, but advancements in pollution control and cleaner combustion technologies aim to minimize their environmental impact. Understanding and managing flue gases are essential for sustainable energy production and air quality management.
