Abstract: The invention generally relates to foam ceramics (3) and to filters comprising such a foam ceramic, and to a method for producing foam ceramics and filters comprising or made of such a foam ceramic. Another aspect relates to the use of the foam ceramic (3) and of a filter comprising or made of such a foam ceramic.

Abstract: The invention relates to a burner, in particular a radiant burner, for the combustion of a gas mixture of fuel gas and an oxygen carrier gas, with a burner plate with passage channels for the throughflow of the gas mixture from a mixing chamber side to a combustion side, wherein, on the combustion side, combustion channels with an enlarged cross-section compared with the passage channels connect to the passage channels, wherein flow obstacles for a contact with the combustion flame are arranged in the combustion channels and the flow obstacles are made of a material which has a higher thermal conductivity than the material of the burner plate.
