Abstract
Method and apparatus for cleaning sulphur and nitrogen containing flue gases by supplying a gaseous reagent such as ammonia gas. The reaction mixture is converted in a reaction chamber through which the reactants flow at a pressure of between 1 and 5 bar under the action of electron beams. The electron beams are injected into the reaction chamber from the vacuum required at the beam source through at least one pressure step stage surrounding the beam path.
