Abstract: A method for treating odorous gases of a chemical pulp mill, according to which method odorous gases are combusted in a separate combustion device and flue gas generated therein is scrubbed. The scrubbed flue gas is led into a recovery boiler. The flue gas is scrubbed in a series of scrubbers wherein scrubbing solution discharged from one scrubber may be fed to a preceding scrubber.

Abstract: An arrangement is disclosed for supplying an air jet form to the furnace of a recovery boiler, where the furnace has a front wall, a rear wall and side walls. Black liquor spraying devices are disposed on the furnace walls at one or several levels of the furnace. A plurality of air ports are located at several horizontal levels for introducing air into the furnace from an air supply. In the arrangement for the secondary air flows, two horizontal air levels at different elevations are arranged above the lower primary levels and below the black liquor sprayer. Secondary air is supplied from two opposite walls and the air ports from each of the two levels are located so that the air jets are introduced in an interlaced pattern having an even number of jets on one opposite wall and an uneven number of jets on the other opposite wall. The air jets of said at least two air levels are located substantially one above each other in substantially vertical rows.

Abstract: The present invention relates to a method for reducing nitrogen oxide emissions in combustion. Fuel is combusted in a first zone, whereby nitrogen oxides are generated. Supplementary fuel is fed in another zone under reducing conditions. At the same time, the temperature is adjusted so that nitrogen oxides convert essentially to hydrogen cyanide. Finally, air is fed in for finalizing the combustion and converting the hydrogen cyanide into nitrogen.
