Abstract

A method for reducing emissions of detrimental nitrogen compounds from the chemical cycle of a pulp mill. The method comprises supplying ammonia-containing vent gases separated from salt smelt to the furnace of a boiler (1, 10) at a point where the fuel has mainly burnt, whereby the ammonia reacts with the nitrogen oxide present in the furnace to form molecular nitrogen.
