2126073 9311855 PCTABS00022 The object of the invention is a method to purify gases, such as combustion gases, in which method oxides of nitrogen and sulphur are converted into solid particles by an electron beam coming from an electron source (1) with the aid of added base. By the present methods oxides of nitrogen and sulphur cannot be removed effectively. In the method of the invention particles charged in the electron beam are guided with an external electric field to gather on a collection sheet (5) into a layer (7) which can be cleaned at desired time periods.
