Abstract: In an apparatus and method for optimizing the exhaust gas burnout in combustion plants having a solid bed combustion zone and an exhaust gas burnout zone wherein oxygen-containing gas is injected into the exhaust gas flow in the burnout zone by way of a plurality of secondary gas injection nozzles, wherein each injection nozzle is provided with a control valve, means are provided for determining the presence of incompletely burned exhaust gas components in the exhaust gas burn out zone and a control unit converts the signals into control signals by which the valves or group of valves are individually controlled so as to inject oxygen containing gas into the exhaust gas flow in order to concentrate the injection of the oxygen containing secondary gas into the areas in which incompletely burned exhaust gas components are present.

Abstract: It is the object of the invention to provide a material for retaining polyhalogenated compounds, the material avoiding the drawbacks of activated carbon and polyolefins. The object is accomplished by the use of a material for retaining polyhalogenated compounds, having a filler, which is suitable for adsorbing polyhalogenated compounds, and a polyolefin matrix, into which the material is completely incorporated and enclosed.
