The flue gas cleaning system is usually one of the most costly elements of the installation to the incineration of hazardous waste. Adapting the system to the actual needs could therefore bring obvious economic benefits.

The paper presents the method of the preselection of the configuration of the cleaning system based on knowledge of the level of concentration of selected components of the raw exhaust gas (sulfur dioxide, hydrogen chloride, hydrogen fluoride, total dust, mercury, cadmium and thallium, and other heavy metals). Twelve examples of flue-gas cleaning systems were proposed and extreme concentration values of the substances in the raw gases were determined for them. The values have been estimated in a such way that the given system permit yet to remove these substances from combustion gases to the level below the right emission limit values in force in the European Union for waste incineration.
