RECOMBINER ELEMENT

摘要

The invention relates to a recombiner element (4) comprising a plurality of catalyst elements (8) that are arranged in a common housing (6) and that trigger a recombination reaction with oxygen when hydrogen is carried along in a feed gas flow, the housing (6) surrounding the catalyst elements (8), which are arranged therein, in a funnel-type way in such a manner that the heat released by the recombination reaction supports the gas flow inside the housing (6) by a convection effect, which recombiner element safeguards a reliable removal of the hydrogen from the gas mixture with an especially high degree of operational safety even under comparatively extreme conditions or scenarios of said type. According to the invention, at least one of the catalyst elements (8) arranged inside the housing (6) has a predetermined ignition zone (20) in which a surface temperature of more than 560°C is produced in the convective operation at ambient conditions of approximately 1 bar and 100°C at a hydrogen concentration in the feed gas flow of more than 5% by volume.
