Abstract: A reactor for reducing the contents of nitrogen oxides and sulphur oxides in combustion gases. The reactor is in the form of a post-combustion chamber to be connected after a combustion chamber. The reactor has a casing including a generally cylindrical main part transforming at its top into a dome-shaped outlet part with an outlet opening. Around the casing of the reactor, there is provided a heat-insulated wall whose inner side has substantially the same shape as the casing and which is eccentrically disposed in relation to the casing. The casing of the reactor accommodates a partition which is conical and has its apex directed towards the outlet opening. A gap is formed between the shell and the partition. At the inlet end of the shell, an inlet funnel is provided at a certain distance from the inlet end as so to form a gap. A heat exchanger is provided for preheating secondary air supplied through a secondary air intake into the gap between the casing and the wall at a certain distance from the opening.

Abstract: An incinerator apparatus consists of a container with an inlet for gaseous or particulate, combustible material together with combustion air, and has an outlet for combustion products, the walls of the container, and possible walls disposed in the interior of the container, being designed for the generation of vortices in the material flowing through the container from the inlet to the outlet. At least the surfaces of the walls facing the inner space of the container include a substance which has the capability to catalyze the oxidation of carbon and carbon compounds in the combustion in the apparatus.
