    摘要: The invention relates to a reformer for converting fuel and oxidising agent into a reformate, the reformer comprising an oxidising zone to which a mixture of fuel and oxidising agent is supplyable via a first fuel supply and a first oxidising agent supply and an injection and mixture formation zone disposed downstream of the oxidising zone to which further fuel is supplyable via a second fuel supply, a second oxidising agent supply being provided via which further oxidising agent is supplyable to the injection and mixture formation zone. According to the invention it is contemplated that the second oxidising agent supply is, relative to the second fuel supply, arranged so that it generates a barrier oxidising agent cushion in the area in front of the second fuel supply to prevent a heat transfer from the mixture from the oxidising zone to the second fuel supply. The invention further relates to a method for operating such a reformer.

    摘要: The invention relates to a method for regenerating a reformer fed with a mixture of fuel and an oxidant having a mean air number λ1 in continuous reformer operation, the air number being varied for the purpose of regenerating the reformer. In accordance with the invention it is provided for that regeneration occurs in a shutoff phase of the reformer in that the reformer is operated during several successive time intervals with an air number λ2 higher than in reformer operation (λ2>λ1). Again in accordance with the invention it may be provided for that regeneration occurs in a starting phase of the reformer in that the reformer is continually operated with an air number increased as compared to reformer operation λ2>λ1 until a critical temperature threshold is attained. The invention relates furthermore to a system including a reformer and a controller for implementing a method in accordance with the invention.
