Abstract

An apparatus for the recombination of hydrogen in a gas mixture, in particular for a nuclear power station, during the operation of which unintentional ignition of the gas mixture is avoided in a particularly reliable way. The apparatus contains a catalyst configuration that is disposed in a housing through which the gas mixture can flow by free convection in the operating situation and the catalyst configuration is assigned a flame retention device. In this case, a sediment trap is preferably integrated into the flame retention device, so that hot catalyst particles that become detached from the catalyst configuration are reliably prevented from flowing out counter to the direction of flow of the gas mixture.
