The invention relates to a method for cleaning flue gas, the flue gas to be cleaned and a sorption agent starting material in the form of a solid being injected into a reactor chamber of a fluidized-bed reactor, and a liquid being injected into the reactor chamber separately from the flue gas and the sorption agent starting material, the sorption agent starting material being contacted with the liquid in the fluidized-bed reactor and being converted to a sorption agent in the form of a solid.

A decomposer for an organohalogen compound, containing iron particles comprising iron and iron oxide, wherein the iron particles have a metallic iron content of 15% or more by mass, wherein the metallic iron content is a content of metallic iron in the outermost surface layer of the iron particles to which the ion beam etching has been applied twice under the following etching conditions: degree of vacuum in a chamber: 2.010.sup.2 Pa accelerating voltage of an ion gun: 10 kV emission current: 10 mA etching time: 14 seconds.
The decomposer need not contain copper and has the ability to satisfactorily decompose an organohalogen compound. A method for producing the decomposer is also provided.

An exhaust gas processing device preheats processing target exhaust gas in the presence of moisture with heat from at least either an electric heater or a heat exchanger and subsequently thermally decomposes the exhaust gas with an atmospheric pressure plasma. A device main body has a heating decomposition chamber therein. A plasma generator is installed at a top surface portion of the device main body. A reactor has a cylindrical shape and is installed within the device main body such that an upper end opening thereof is directed toward a plasma emission port of the plasma generator. A moisture supply unit is provided at an inlet side of the device main body. At least either the electric heater or the heat exchanger is disposed in a first space.

An inlet assembly includes: a combustion chamber module defining a plenum configured to supply combustion reagents to its combustion chamber, the combustion chamber module having a mount configured to interface with a common head which defines at least one gallery configured to supply the combustion reagents, the mount comprising a plurality of feed apertures positioned for fluid communication of the combustion reagents between the gallery and the plenum. In this way, a mount which is suited to its combustion chamber module interfaces with a standard or common head, which enables the combustion reagents to be supplied from the gallery of the common head via the mount and to the plenum of the combustion chamber module. This enables a common head to be used for different combustion chamber modules, which reduces the number of parts required for the assembly and maintenance of the abatement apparatus.
