Thermal power plants - flue gas purification

One of the most important problems today is the formation of greenhouse gases, mainly caused by the emission of flue gases in thermal power plants: carbon dioxide (CO2), sulfur dioxide (SO2) and nitrogen oxides (NOx) ("acid rain"). CO2 emissions are inevitable and related to the fuel combustion process (carbon capture techniques). Sulfur dioxide emissions are reduced by cleaning coal and by applying wet and dry flue gas desulfurization. The injection of absorbents can be applied in the combustion chamber or in the flue gases. Nitrogen oxide emissions are reduced by proper fuel selection and advanced solutions in the construction of the combustion chamber. Burners with low NOx emissions are used.
