Abstract

To reduce the content of N2O in flue gases from a boiler with an atmospheric or pressurized fluidized bed of the stationary or circulating type, at least one active medium, which comprises hydrogen gas and/or an active, hydrogen-containing compound, preferably hydrogen peroxide and/or methane, is injected before, during and/or after the separation of bed particles from flue gases generated. A boiler intended for the purpose has injection arrangements 29-34 for the active substance in the combustion chamber 21 and/or flue-gas ducts 27 and/or particle separator 24 of the boiler. <IMAGE>
