Abstract
This article shows the methods and techniques that are used for cleaning exhaust fumes from dust–gas particles. The pollutants come from a complicated electricity production process in a thermal power station, whose main fuel is a hard coal or a brown coal. In the recent years, using purification installations has been the result of changing regulations in the field of environmental protection and increasing public awareness. The methods are aimed to reduce nitrogen oxides, sulphur oxides and dust emissions to the environment, not exceeding the emission limit values for individual chemical compounds.
