For binding the pollutants in flue gases downstream of combustion plants, especially for flue gas desulphurisation, it is proposed to admix NaHCO3 and/or Na2CO3 as an additive to the flue gas cooled to about 120 DEG to 320 DEG C and to precipitate the resulting salt in a fabric filter. To facilitate purification of the salt formed and its further use, the fly ash is already precipitated before the additive is charged, and the residence time on the fabric filter is thereby also extended by increasing the period between two cleaning steps, so that the result is an improvement in the utilisation of the additive.

Title
