摘要： Methods for the heat treatment of a material flow and the cleaning of resulting exhaust gases are disclosed. The material flow may be preheated in a preheating zone, burned in a sintering zone, and cooled in a cooling zone. Exhaust gases of the sintering zone may flow through a preheater and be used for preheating the material flow. The exhaust gases leaving the preheater may be cooled at least partially in a comminuting device in interconnected operation or at least partially in a cooling device in direct operation. Exhaust gases may then be at least partly dedusted in a dust filter. A temperature of the dedusted exhaust gas may then be raised before the exhaust gas is cleaned of pollutants in at least one catalyst. A temperature at which the exhaust gases flow through the catalyst in direct operation may be higher, at least in phases, than a temperature at which the exhaust gases flow through the catalyst in interconnected operation.

摘要： A plant may include an offgas-producing treatment apparatus for mechanical and/or thermal treatment of an inorganic material, an oxidation catalyst downstream of the offgas-producing treatment apparatus in a flow direction of the offgas, a reduction catalyst downstream of the oxidation catalyst in the flow direction of the offgas, and a temperature-affecting apparatus for affecting the temperature of the offgas upstream of the oxidation catalyst and/or between the oxidation catalyst and the reduction catalyst. In some examples, the the temperature-affecting apparatus is controllable and may comprise at least one of an auxiliary preheater, a mixing-in device for a fluid, or a heat exchanger.

摘要： A method for cleaning bypass gases of the cement or mineral industry includes cooling down a removed bypass gas from a cement or mineral processing plant to a temperature of between 500° C. and 150° C., and coarsely dedusting the bypass gas, the dust burden being reduced by 30 to 95%. After the dedusting step, the gaseous constituents contained in the partly dedusted bypass gas are reduced in a reducing step. The partly dedusted bypass gas is further finely dedusted. The gaseous constituents reducing step includes at least a catalytic reduction of one or more of nitrogen oxides, hydrocarbons, and carbon monoxide.

摘要： An offgas treatment apparatus having a reduction catalyst and an oxidation catalyst downstream of the reduction catalyst may also include a temperature-affecting apparatus for the offgas positioned between the reduction catalyst and the oxidation catalyst. In some examples, the apparatus may include a second temperature-affecting apparatus for the offgas positioned upstream of the reduction catalyst. At least one of the first or second temperature affecting apparatuses may comprise a heat exchanger, a preheating apparatus, an auxiliary heater, or a mixing-in device for a fluid, for instance. In some examples, the apparatus may involve a dust filter positioned upstream of the reduction catalyst.

摘要： A method for decreasing an amount of a harmful substance of a chlorine-containing off-gas stream formed or used in a thermal treatment of a material may comprise dividing the chlorine-containing off-gas stream into a main stream and a substream, separating at least some chlorine from the main stream, lowering an amount of the harmful substance in the main stream by introducing a chlorine-containing additive into the main stream to enhance separation of the harmful substance, and filtering the substream such that a filter cake separated from the substream comprises at least part of the chlorine-containing additive.
