ABSTRACT A reactor for reducing the contents of nitrogen oxides and sulphur oxides in combustion gases is in the form of a post-combustion chamber to be connected after a combustion chamber. The reactor has a casing (10) consisting of a generally cylindrical main part (11) passing at the top into a dome-shaped outlet part (12) with an outlet opening (13). Around the casing (10) of the reactor, there is provided a heat- insulated wall (20) whose inner side has substantially the same shape as the casing (10) and which is eccen- trically disposed in relation to the casing (10). The casing (10) of the reactor accommodates a partition (15) which is conical and has its apex directed to- wards the outlet opening (13). A gap (17) is formed between the shell (11) and the partition (15). At the inlet end (14) of the shell, an inlet funnel (18) is provided at a certain distance from the inlet end so as to form a gap (19). A heat exchanger (40) is provided for preheating secondary air supplied through a secondary air intake (25) into the gap (21) between the casing (10) and the wall (20) at a certain distance from the opening (13). At the bottom, the gap (21) is connected to a collecting box (23) and an outlet pipe (24). Fig. 1 elected for publication
