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.
